Description

  The present invention relates to a stop cock device.

  Conventionally, a stop cock device is known in which a cylindrical strainer is attached in a flow path provided with a stop cock member for opening and closing the flow path (see, for example, Patent Document 1). In this water stop cock device, the foreign water in the running water is removed by allowing the running water flowing into the flow path to pass from the inside to the outside of the filter medium provided on the outer periphery of the strainer.

JP 2010-221125 A

  Incidentally, a dust catch ring for collecting foreign substances is usually provided at the upstream end of the strainer provided in the water stop cock device. This dust catch ring has an annular groove that opens on the downstream side, and collects foreign matter that has fallen off from the filter medium when the strainer is removed for maintenance.

  However, in the conventional water faucet device, a large gap is formed between the water faucet member extending from the upstream side of the strainer to the inside of the strainer and the dust catch ring. Therefore, there has been a problem that the foreign matter peeled off from the filter medium when the strainer is removed enters the water stop cock.

  Therefore, in order to reliably collect foreign matter with the dust catch ring and suppress the entry of foreign matter into the stop cock, it is considered to simply reduce the gap between the stop cock member and the dust catch ring. It is done. However, in this case, there is a problem that a necessary flow rate cannot be secured due to a narrow water passage.

  This invention is made | formed in view of the above, The objective is to provide the water stop apparatus which can suppress the penetration | invasion of the foreign material into a water stop cock, ensuring a required flow volume.

In order to achieve the above object, the present invention is a water stop cock device (for example, a water stop cock device 50 described later) capable of switching between an open state and a closed state, and a first flow path (for example, a first flow path described below). A main body having a flow path 61) and a second flow path (for example, a second flow path 62 described later) communicating with the downstream side of the first flow path and extending in a direction intersecting the first flow path A filter medium (for example, described later), which is attached to the outer periphery of a portion (for example, a body portion 6 to be described later) and detachably attached to the first flow path, and flows from the upstream side of the first flow path. A cylindrical strainer (for example, a strainer 8 to be described later) that removes foreign matter in running water by passing the mesh 813 from the inside to the outside and guiding it to the second flow path, and the strainer from the upstream side of the strainer. Extending to the inside of the first flow path and proceeding in the axial direction of the first flow path. A stop cock member (for example, a stop cock member 7 to be described later) that opens and closes the first flow path, and an annular member (for example, a dust catch ring 83 to be described later) attached to the inner peripheral surface of the strainer. And the water stop cock member has a large gap formed between the annular member and the water stop cock member when the first flow path is opened by retreating to the downstream side of the first flow path. In addition, there is provided a water stop cock device configured such that the gap is formed small when the first flow path is closed by advancing upstream of the first flow path.

  The stop cock member includes a small diameter portion (for example, an upstream small diameter portion 731 described later) provided on the upstream side and a large diameter portion (for example, described below) provided on the downstream side and having a larger outer diameter than the small diameter portion. A large-diameter portion 732), and when the first passage is opened by retreating to the downstream side of the first passage, the axial position of the small-diameter portion is disposed at the position of the annular member, When the first flow path is closed by advancing upstream of the first flow path, the axial position of the large diameter portion is preferably disposed at the position of the annular member.

  When the water faucet member advances to the upstream side of the first flow path and closes the first flow path, the axial position of the upstream end of the large diameter portion is arranged at the position of the annular member. It is preferable.

Here, FIG. 3 is an exploded perspective view of the water faucet device 50 according to the present embodiment. FIG. 4 is a longitudinal sectional perspective view of the water stop cock device 50 in the open state. FIG. 5 is a longitudinal sectional view of the water stop cock device 50 in the opened state. FIG. 6 is a longitudinal sectional view of the water stop cock device 50 in the closed state. FIG. 7 is a cross-sectional view of the main body 6 of the water stop cock device 50 according to the present embodiment. FIG. 7 shows only the main body 6.

  As shown in FIG. 3, the stop cock device 50 includes a main body portion 6, a stop cock member 7, a strainer 8, and a cap 9. The water stopper member 7, the strainer 8, and the cap 9 are all disposed on the same axis X as the first flow path 61 of the main body 6 described later.

  The main body 6 includes a first flow path 61 and a second flow path 62. The first flow path 61 is configured by a substantially cylindrical pipe extending linearly in the vertical direction. The second flow path 62 is configured by a substantially cylindrical pipe that communicates with the downstream end (the upper end in FIG. 3) of the first flow path 61 and extends in the horizontal direction orthogonal to the first flow path 61. That is, the first flow path 61 and the second flow path 62 communicate with each other with their center axes X and Y orthogonal to each other.

  The upstream side (downward in FIG. 3) of the first flow path 61 is formed with a smaller outer diameter than the downstream side, and is inserted into an attachment hole (not shown) formed in the floor F. Further, a male screw portion 61a is formed on the outer periphery of the upstream end of the first flow path 61, and a female screw on the water supply source pipe (not shown) side is screwed into the male screw portion 61a. As a result, the water supply source pipe is connected to the upstream end of the first flow path 61, and the water supplied from the water supply source pipe is supplied into the first flow path 61.

  As shown in FIGS. 4 to 6, the first channel 61 includes an upstream channel 611 provided on the upstream side, a downstream channel 612 provided on the downstream side, and these upstream channels 611. And a water stop hole portion 613 provided between the downstream side flow path 612 and the downstream side flow path 612.

  The upstream channel 611 has a smaller inner diameter than the downstream channel 612 and has a constant diameter in the axis X direction. Water is supplied to the upstream channel 611 from a water supply source pipe.

  The downstream channel 612 has a larger inner diameter than the upstream channel 611. As will be described later, the strainer 8 is inserted and accommodated in the downstream channel 612 from the downstream side (downstream end) in the axis X direction along the inner peripheral surface. Therefore, the inner peripheral shape of the downstream flow path 612 is a shape along the outer peripheral shape of the strainer 8. That is, corresponding to a small-diameter portion 811 and a large-diameter portion 812 of the strainer 8 to be described later, the downstream-side channel 612 includes a small-diameter channel 612a provided on the upstream side and a small-diameter channel 612a provided on the downstream side. A large-diameter channel 612b having a large inner diameter is also provided. Thereby, only a slight gap is formed between the inner peripheral surface of the downstream flow path 612 and the outer peripheral surface of the large-diameter portion 812 of the strainer 8, and the large-diameter portion 812 of the strainer 8 exhibits a guide function. Therefore, it is possible to suppress the strainer 8 from being inclined during insertion.

  An internal thread portion 612c is formed on the inner periphery of the downstream end of the downstream channel 612. A male screw portion 9a formed on the outer periphery of the upstream end of the cap 9 connected to the downstream end of the strainer 8 described later is screwed into the female screw portion 612c.

The water stop hole 613 includes a water stop hole 613a, a valve seat 613b, and a female screw part 613c.
The water stop hole 613a is formed by a hole having a smaller diameter than the upstream flow path 611. The valve seat 613b is formed in a taper shape whose diameter is increased toward the downstream side, and a piece valve 71 provided at the front end of a water stopper member 7 described later is seated. Thereby, the water stop hole 613a is closed and water is stopped. The male screw portion 72 of the water stop cock member 7 is screwed into the female screw portion 613c.

  Here, as shown in FIG. 7, a pair of notch portions 612 f are formed in the bottom surface portion 612 e at the upstream end of the downstream flow path 612. Thereby, when the piece valve 71 of the water stop cock member 7 described later is disengaged from the valve seat 613b, the water is passed through the downstream channel 612.

  As shown in FIGS. 3 to 6, a groove 62 a is formed on the outer periphery of the downstream end of the second flow path 62. The water supply pipe 41 is connected to the second flow path 62 by fitting the water supply pipe 41 into the groove 62a. The second channel 62 is connected to and communicates with the downstream channel 612 of the first channel 61.

  As shown in FIG. 3, the water stopcock member 7 is formed in a substantially cylindrical shape as a whole. The water stopper member 7 includes a piece valve 71, a male screw portion 72, and a spindle 73. The water stopper member 7 has a function of opening and closing the first flow path 61. The length of the stop cock member 7 in the axis X direction is set longer than the length of the downstream flow path 612 in the axis X direction, and the stop cock member 7 is connected to the strainer from the upstream side of the strainer 8 described later. It extends through the inside of 8 to its downstream end.

  The piece valve 71 is provided at the front end of the water stopper member 7 and is attached to the front end of the spindle 73 by a screw 7a. When the piece valve 71 is seated on the valve seat 613b, the first flow path 61 is closed.

  The male screw portion 72 has a larger diameter than the piece valve 71 and is screwed into the female screw portion 613c of the water blocking hole portion 613 described above. As a result, the position of the stop cock member 7 in the direction of the axis X of the first flow path 61 is adjusted, and the stop cock member 7 is attached and fixed in the first flow path 61. That is, the water stopper member 7 advances and retreats in the direction of the axis X of the first flow path 61 by screwing the male screw portion 72 and the female screw portion 613c, and the piece valve 71 is seated on or removed from the valve seat 613b. The first flow path 61 is opened and closed.

The spindle 73 is formed in a substantially cylindrical shape. A groove 73 a is formed on the downstream end surface of the spindle 73. For example, a flathead screwdriver or the like is fitted in the groove 73a and rotated around the axis X in this state, whereby the water stopper member 7 is connected to the first flow path 61 via the screwing of the male screw portion 72 and the female screw portion 613c. Advancing and retreating in the X direction.
An O-ring 73 b is attached to the outer periphery on the downstream side of the spindle 73. Thereby, the sealing property of the spindle 73 and the cap 9 described later is ensured.
A more detailed structure of the spindle 73 will be described in detail later.

  The strainer 8 is inserted in the axis X direction from the downstream side (downstream end) of the first flow path 61 along the inner peripheral surface of the first flow path 61, and is detachably attached to the first flow path 61. The strainer 8 includes a strainer main body 81, a connecting portion 82, and a dust catch ring 83. The strainer 8 is formed in a cylindrical shape, and the flowing water flowing in from the upstream side of the first flow path 61 is passed from the inside to the outside (mesh 813 described later) and guided to the second flow path 62, thereby Remove foreign material.

  The strainer body 81 is formed in a substantially cylindrical shape. The strainer main body 81 includes a small diameter portion 811, a large diameter portion 812, and a mesh 813.

  The small diameter portion 811 constitutes the distal end side of the strainer 8 in the insertion direction, that is, the upstream side of the strainer body 81, and is formed in a substantially annular shape. The small diameter portion 811 has a smaller diameter than a large diameter portion 812 described later. A dust catch ring 83 described later is detachably attached to the inner periphery of the small diameter portion 811. In addition, an annular O-ring 81 a is attached to the outer periphery of the small diameter portion 811, thereby ensuring the sealing performance between the first flow path 61 and the strainer 8.

  The large diameter portion 812 constitutes the proximal end side in the insertion direction of the strainer 8, that is, the downstream side of the strainer body 81, and has a larger diameter than the small diameter portion 811 described above. More specifically, the large diameter portion 812 has a larger diameter than the outer diameter of the O-ring 81a attached to the outer periphery of the small diameter portion 811. The large diameter portion 812 has a rib 812a and an annular portion 812b.

Four ribs 812a are provided at substantially equal intervals in the circumferential direction. These ribs 812a extend in the direction of the axis X of the strainer 8, that is, the insertion direction of the strainer 8, and connect the above-described small diameter portion 811 and the annular portion 812b described later.
The annular portion 812b constitutes a large-diameter portion 812 together with the rib 812a, and has a larger diameter than the small-diameter portion 811 described above.

  Note that the inner diameter of the small diameter portion 811 and the inner diameter of the large diameter portion 812 are substantially the same. That is, the inner peripheral surface of the small diameter portion 811 and the inner peripheral surfaces of the rib 812a and the annular portion 812b of the large diameter portion 812 are formed to be connected to each other. Therefore, the rib 812a of the large diameter part 812 is thicker than before, and the strength of the strainer 8 is improved.

  Further, as shown in FIG. 5 and the like, a tapered portion 814 having a diameter increasing toward the downstream side is formed at the boundary between the small diameter portion 811 and the large diameter portion 812 of the strainer 8. As described above, the inner peripheral shape of the downstream flow path 612 constituting the first flow path 61 is a shape along the outer peripheral shape of the strainer 8. That is, the strainer 8 has an outer diameter along the inner diameter of the downstream flow path 612 of the first flow path 61. Therefore, a tapered portion 612d having the same inclination angle as that of the tapered portion 814 is formed at the boundary between the small-diameter channel 612a and the large-diameter channel 612b constituting the downstream channel 612. Thereby, when the strainer 8 is inserted, the small diameter portion 811 is easily guided on the upstream side.

  A predetermined gap is secured in the axis X direction between the tapered portion 814 of the strainer 8 and the tapered portion 612d of the downstream flow path 612. As a result, when the dust catch ring 83 is detached in the downstream channel 612 when the strainer 8 is removed as will be described later, the strainer 8 can be further pushed upstream, and the dust catch ring 83 is The strainer 8 can be fitted and taken out at the tip.

  As shown in FIG. 3, the mesh 813 is provided so as to cover the inner periphery of the four ribs 812a described above. The mesh 813 functions as a filter medium. The mesh 813 is made of resin or metal.

  The connecting portion 82 is formed in a substantially cylindrical shape, and has an outer diameter smaller than that of the strainer body 81 described above. The connecting portion 82 has an outer diameter that is substantially the same as the inner diameter of a male screw portion 9a of the cap 9 described later, and the cap 9 is attached and fixed to the strainer 8 by being fitted to the inner periphery of the male screw portion 9a. An annular O-ring 82 a is attached to the outer periphery of the connecting portion 82, so that the tightness between the strainer 8 and the cap 9 is ensured.

  The dust catch ring 83 is detachably attached to the inner periphery of the tip of the small diameter portion 811 constituting the strainer body 81. The dust catch ring 83 is formed by an annular member in which an annular groove 83a that opens to the downstream side is formed. By the dust catch ring 83, dust that peels off from the mesh 813 or the like of the strainer 8 is received by the groove 83 a, so that the entry of dust into the water blocking hole 613 or the like in the first flow path 61 is suppressed.

  The cap 9 is formed in a substantially cylindrical shape. A male screw portion 9 a is formed on the outer periphery on the upstream side of the cap 9. The male threaded portion 9a is screwed into the female threaded portion 612c of the downstream channel 612 described above. The connecting portion 82 of the strainer 8 is fitted to the inner periphery of the male screw portion 9a via an O-ring 82a.

  A groove 9b and a circular hole 9c are formed on the downstream end surface of the cap 9. For example, a minus driver or the like is fitted in the groove 9b and rotated around the axis X in this state, whereby the strainer 8 in the direction of the axis X of the first flow path 61 is engaged through the screwing of the male screw 9a and the female screw 612c. And the strainer 8 is attached and fixed in the first flow path 61. Further, the above-mentioned stop cock member 7 is inserted into the circular hole 9c, and the opening and closing of the first flow path 61 by the stop cock member 7 is performed by inserting a minus driver or the like through this circular hole 9c.

Next, the structure of the spindle 73 that is characteristic of the water faucet device 50 according to the present embodiment will be described in detail with reference to FIGS. Here, FIG. 8 is an enlarged view of a main part of FIG. FIG. 9 is an enlarged view of a main part of FIG.
The water faucet member 7 according to the present embodiment has a gap between the dust catch ring 83 and the water faucet member 7 when the first flow passage 61 is opened by retreating to the downstream side of the first flow passage 61. It is configured to be formed large. Further, when the first flow path 61 is closed by advancing upstream of the first flow path 61, the gap is formed to be small.

  As shown in FIGS. 8 and 9, the spindle 73 includes an upstream small diameter portion 731, a large diameter portion 732, a downstream small diameter portion 733, and a tapered portion 734.

  The upstream small diameter portion 731 constitutes the upstream end of the spindle 73 and is connected to the male screw portion 72 described above. The upstream small diameter portion 731 has a substantially cylindrical shape, and has a smaller diameter than a large diameter portion 732 described later.

  As shown in FIG. 8, the upstream small diameter portion 731 is configured so that the stop cock member 7 moves backward to the downstream side of the first flow path 61 to open the first flow path 61, that is, the piece valve 71 is the valve seat. When the seat 613b is disengaged and the water passing state is reached, the position in the direction of the axis X overlaps with the position of the dust catch ring 83. Thereby, when the 1st flow path 61 is an open state (water flow state), a big clearance gap is formed between the water stop cock member 7 and the dust catch ring 83, and a required flow volume is ensured now. Yes.

  The large diameter portion 732 forms a central portion of the spindle 73 in the axial direction, and is connected to the above-described upstream small diameter portion 731 and a downstream small diameter portion 733 described later. The large diameter portion 732 has a substantially cylindrical shape, and has a larger diameter than the upstream small diameter portion 731 and the downstream small diameter portion 733. The large-diameter portion 732 has an outer diameter slightly smaller than the inner diameter of the dust catch ring 83 so that the large-diameter portion 732 can be inserted through the dust catch ring 83 as the stop cock member 7 advances and retreats. It has become.

  As shown in FIG. 9, the large-diameter portion 732 is formed so that the stop cock member 7 advances to the upstream side of the first flow path 61 and closes the first flow path 61, that is, the piece valve 71 is the valve seat. When seated on 613b and the water stop state is reached, the position in the direction of the axis X overlaps with the position of the dust catch ring 83. As a result, when the first flow path 61 is in the closed state (water-stopped state), the gap between the water stop cock member 7 and the dust catch ring 83 is narrowed, so that foreign matter that peels off from the mesh 813 can enter the groove 83a. It is easy to accommodate and collect, and it can control that a foreign material penetrate | invades into a stop cock.

  The downstream small diameter portion 733 constitutes the downstream end of the spindle 73. The downstream small diameter portion 733 is substantially cylindrical, has a smaller diameter than the large diameter portion 732 described above, and has substantially the same diameter as the upstream small diameter portion 731 described above.

  The tapered portion 734 is formed over the entire circumference at the boundary between the upstream small diameter portion 731 and the large diameter portion 732 described above. More specifically, the tapered portion 734 has a position in the direction of the axis X that is downstream of the opening surface 8a on the upstream side of the strainer 8 when the water stopper device 50 is in an open state as shown in FIG. It is formed at a position upstream of the mesh 813.

  The taper portion 734 is formed in a taper shape whose diameter increases toward the downstream side, and the inclination angle is approximately 45 degrees. However, the inclination angle of the tapered portion 734 can be changed as appropriate. Further, the tapered portion 734 flows in from a pair of notches 612f formed in the bottom surface portion 612e of the downstream channel 612 when the stop cock device 50 is in the open state, and is downstream along the axis X direction. It is formed so as to protrude sufficiently outward in the radial direction so that the flowing water that flows vigorously collides directly.

Operation | movement of the water tap apparatus 50 which concerns on this embodiment provided with the above structure is demonstrated collectively with an effect.
First, for example, after removing foreign matter from the strainer 8 for maintenance, when attaching the strainer 8 to the water stop cock device 50, the cap 9 is attached to the downstream end thereof, and the dust catch ring 83 is attached to the upstream end thereof. In this state, the strainer 8 is inserted into the downstream channel 612 in the axis X direction from the downstream side (downstream end) of the first channel 61. At this time, the water stop cock member 7 is already attached to the first flow path 61, and the water stop cock device 50 is in a water stop state.

Here, as described above, in the present embodiment, the strainer 8 has a small diameter portion 811 formed on the distal end side (upstream side) in the insertion direction and a small diameter portion 811 formed on the proximal end side (downstream side) in the insertion direction. A large-diameter portion 812 having a larger outer diameter.
Accordingly, by providing the large-diameter portion 812, the gap between the first flow path 61 (downstream flow path 612) and the inner peripheral surface can be reduced, so that the large-diameter portion 812 exhibits a guide function. The strainer 8 is prevented from tilting. As apparent from FIG. 6, when the strainer 8 is inserted into the downstream channel 612 in the axial X direction from the downstream end of the first channel 61, the large-diameter portion 812 of the strainer 8. Moves along the inner peripheral surface of the downstream flow path 612. At this time, the inner peripheral shape of the downstream channel 612 is a shape along the outer periphery of the strainer 8, and is between the inner peripheral surface of the downstream channel 612 and the outer peripheral surface of the large-diameter portion 812 of the strainer 8. Only a slight gap is formed in the. Therefore, since the large diameter part 812 of the strainer 8 exhibits the function of a guide more reliably, it can suppress more reliably that the strainer 8 inclines at the time of insertion. Therefore, according to the present embodiment, the strainer 8 can be easily attached, and the assemblability is improved. The same applies to the removal, and the strainer 8 can be prevented from being tilted. Therefore, the strainer 8 can be easily removed, and the assemblability is improved.

Further, in the present embodiment, the downstream flow path 612 of the first flow path 61 to which the strainer 8 is detachably attached is provided on the downstream side of the small diameter flow path 612a and the small diameter flow path 612a. And a large-diameter channel 612b having an inner diameter larger than that of the small-diameter channel 612a. The large diameter portion 812 of the strainer 8 is configured to have an outer diameter that is larger than the inner diameter of the small diameter channel 612a and smaller than the inner diameter of the large diameter channel 612b.
Thereby, only a slight gap is formed between the inner peripheral surface of the downstream flow path 612 (large diameter flow path 612b) and the outer peripheral surface of the large diameter portion 812 of the strainer 8, and a large gap is formed. Since it can avoid, the large diameter part 812 of the strainer 8 can exhibit the function of a guide, and it can suppress that the strainer 8 inclines at the time of insertion.

  Moreover, in this embodiment, the large diameter part 812 of the strainer 8 was comprised including the some rib 812a extended in an insertion direction (axis X direction). Thereby, the guide function of the large diameter part 812 of the strainer 8 mentioned above is more reliably exhibited, and the above-mentioned effect is more reliably exhibited.

Further, conventionally, when an elastic member such as an O-ring is attached to the outer periphery of the strainer at the tip end side, the strainer is inclined at the time of attachment / detachment, so that the elastic member comes into contact with a corner or the like in the flow path and is damaged. However, there was a risk of water leakage.
On the other hand, in this embodiment, although the O-ring 81a as an annular elastic member is attached to the outer periphery of the small-diameter portion 811 of the strainer 8, it is possible to suppress the strainer 8 from being inclined when the strainer 8 is attached and detached as described above. The O-ring 81a can be prevented from coming into contact with the corners in the first flow path 61 and being damaged, and the risk of water leakage can be suppressed.

Also, conventionally, when the strainer is removed, the strainer tilts and the tip of the strainer comes into contact with the outer peripheral surface of the spindle arranged inside the strainer, so that the dust catch ring attached to the strainer tip is released and flows. Sometimes it fell into the street and left behind.
On the other hand, in this embodiment, although the water stop cock member 7 is provided extending from the upstream side to the inside of the strainer 8 relative to the strainer 8, the above-described problems can be suppressed. That is, in the present embodiment, the dust catch ring 83 as an annular member in which an annular groove 83a that opens to the downstream side is formed on the inner peripheral surface of the tip of the small diameter portion 811 is detachably attached. As described above, when the strainer 8 is removed, the strainer 8 can be prevented from tilting, so that the tip of the strainer 8 can be prevented from coming into contact with the stopcock member 7, and the dust catch ring is detached and left in the flow path. Can be suppressed.

  Further, as described above, the water faucet device 50 is closed during maintenance, and the first channel 61 and the second channel 62 are in a water-stopped state. At this time, as shown in FIG. 6, the stop cock member 7 is adjusted to a position advanced upstream, and the piece valve 71 is seated on the valve seat 613b. Therefore, the running water supplied from the water supply source pipe into the upstream flow path 611 cannot pass through the water blocking hole 613. Thereby, the 1st flow path 61 and the 2nd flow path 62 will be in a water stop state.

  At this time, as shown in FIG. 9, the large-diameter portion 732 is disposed so that the position in the axis X direction overlaps with the position of the dust catch ring 83. Thus, according to the present embodiment, when the first flow path 61 is in a closed state (water-stopped state), the gap between the water stop cock member 7 and the dust catch ring 83 is narrowed, so that the first flow path 61 is peeled off from the mesh 813. The foreign matter can be more reliably accommodated and collected in the groove 83a, and the foreign matter can be more reliably suppressed from entering the water stop cock.

In the example shown in FIG. 9, the axial position of the upstream end of the large diameter portion 732 is disposed at the position of the dust catch ring 83. Accordingly, a necessary gap (flow path) can be ensured between the dust catch ring 83 and the water stopper member 7 immediately after the first flow path 61 is in the closed state (water stop state). However, the present invention is not limited to this, and the central portion or the downstream side of the large diameter portion 732 may be disposed at the position of the dust catch ring 83.

  After attaching the strainer 8 to the stop cock device 50 as described above, as shown in FIG. 5, the stop cock device 50 is opened, and the first flow path 61 and the second flow path 62 are passed through. And Specifically, the stop cock member 7 is moved backward, and the piece valve 71 is removed from the valve seat 613b. As a result, the flowing water supplied from the water supply source pipe into the upstream flow path 611 passes through the water blocking hole 613 and a pair of notches formed in the bottom surface section 612e on the upstream side of the downstream flow path 612. It flows into the downstream flow path 612 through 612f (see FIG. 7).

  At this time, as shown in FIG. 8, the position of the upstream small diameter portion 731 overlaps the position of the dust catch ring 83 in the position in the axis X direction. Thereby, according to this embodiment, when the 1st flow path 61 is an open state (water flow state), a big clearance gap can be formed between the water stop cock member 7 and the dust catch ring 83, and a required flow volume is ensured. it can. Therefore, according to the present embodiment, entry of foreign matter into the water stop cock can be suppressed while ensuring a necessary flow rate.

  Next, the flowing water that has flowed into the downstream flow path 612 flows into the inside of the strainer 8. At this time, as shown in FIG. 8, the flowing water that flows into the inside of the strainer 8 and vigorously flows downstream along the axis X direction collides with a tapered portion 734 formed on the outer periphery of the spindle 73. Then, as shown by the black arrow in FIG. 8, turbulent flow of running water occurs in the vicinity of the tapered portion 734. Thereby, the flowing water flows downstream between the water stop cock member 7 and the mesh 813 in a state where the momentum (speed) is weakened. Then, after the flow path is bent at a substantially right angle toward the outer peripheral side, it passes through the mesh 813 and is removed from the foreign matter, and then guided to the second flow path 62. Therefore, since the momentum (speed) of flowing water has already been weakened, no turbulent flow is generated even if the flow path is bent at a substantially right angle. That is, according to the present embodiment, since no turbulent flow is generated in the vicinity of the mesh 813, damage to the mesh 813 can be suppressed.

Moreover, according to this embodiment, since a turbulent flow can be suppressed by changing the shape of the water stop cock member 7, it is not necessary to prepare a separate member or process it separately as a turbulent flow suppression measure. Therefore, the number of parts and man-hours can be reduced, the assembling property can be improved, and the cost can be reduced.
Furthermore, the upstream small-diameter portion 731 of the water stopcock member 7 must have a small diameter of a predetermined value or less in order to ensure a predetermined amount or more of flowing water. On the other hand, on the downstream side of the upstream small diameter portion 731, since the turbulent flow can be effectively suppressed by narrowing the space between the strainer 8 and the stop cock member 7, the tapered portion 734 of the present embodiment is It can be said that this is a preferable structure capable of suppressing turbulent flow while ensuring a flow rate. Further, since the diameter of the spindle 73 is increased in order to form the tapered portion 734, the strength of the water stopper member 7 can be improved.

  As described above, the water supply pipe 41 connected to the second flow path 62 is in a water passing state, and flowing water is supplied to the toilet device 100.

  It should be noted that the present invention is not limited to the above-described embodiment, and modifications, improvements, etc. within a scope that can achieve the object of the present invention are included in the present invention.

  In the said embodiment, although the 1st flow path 61 and the 2nd flow path 62 were set as the structure orthogonal to each other, it is not limited to this. What is necessary is just to mutually cross these flow paths.

  In the said embodiment, although the taper part 734 was provided as a guide part, it is not limited to this. For example, a step portion may be provided as the guide portion, and a longitudinal groove extending in the axial direction and deeper toward the upstream side may be formed on the outer periphery of the spindle.
