Here, the valve structure b will be described in detail. As shown in FIGS. 1 and 3, the valve structure b is rotatably fitted in the upper part of the storage space 18 of the stopper box 5, and the lower end of the lot 11 is joined to the upper part. At the outer end of the lower surface, a disk driver 24 having a pair of rotating power transmitting pins 23 sandwiching the rotation positioning pin 21, the center pin 22, and the center pin 22 on the left and right, and a stepped portion 2 of the storage space 18.
A cylindrical case main body 26 whose upper end is engaged with the stopper case 5 is fitted on the inner periphery of the stopper box 5 and is prevented from rotating by a stopper pin 27. ,
29, and the communication space 1 is inserted between the O-rings 28 and 29.
9, a drain groove 30 is formed through the peripheral wall, and guide grooves 31 each having a required width are vertically provided in the left and right peripheral walls from the fitting seat of the lower O-ring 29 to the lower end. A casing 34 having a small-diameter punched hole 32 having a required diameter and an arc-shaped positioning groove 33 having a required width and a required depth formed on the periphery of the upper surface, and an inner peripheral upper end of the casing body 26 of the casing 34. As shown in FIG. 4, a disc-shaped ceramic body 35 to which the upper surface is attached is represented by rectangular coordinates of the X axis and the Y axis, and one end coincides with the X axis of the first quadrant. The other end is provided with a circular arc-shaped communication hole 36 having a required width located in the middle part of the second quadrant. A movable disk 39 formed by recessing the pin holes 38 of Pressed against the upper surface to the surface, board member 4 discoid ceramic that fits in the guide groove 31 which is Tate設 the left and right guide seat 40 the casing 34 protruding from the right and left lower end
As shown in FIG. 5, the center of the guide seat 40 is represented by the X axis and the Y axis, as shown in FIG.
9 has the same phase and the same shape as the communication hole 36, one end of which coincides with the X-axis of the first quadrant, and the other end penetrates the arc-shaped water passage hole 42 located in the middle part of the second quadrant. A fixed disk 44 having a small fan shape extending in the second quadrant and the third quadrant sandwiching the X-axis vertically and having a drain groove 43 having a required depth and communicating from the upper surface to the side surface; A spring 45 has one end engaged with the lower surface, and the other end of the spring 45 is externally fitted to the neck 46 to be seated, and has a screw seat 47 screwed to the inner periphery of the lower part of the stopper box 5. And a seat board 49 having a through-hole 48 penetrating therethrough.

[0010] The operating state of the valve structure b constructed as described above will be described. As shown in FIG. 6A, the communicating hole 36 of the movable disk 39 is fixed to the fixed disk 44.
Is in the same state as the water passage hole 42 in the same state as the water passage state, and from this position, the lever handle 13 is operated clockwise to stop moving the movable disc 39 to the position shown in FIG. It is in the water state and the movable disk 39 is
The state rotated to the position shown in FIG. As described above, since the communication hole 36 of the movable disk 39 does not simultaneously communicate with the water passage hole 42 and the drain groove 43 of the fixed disk 44 during the rotation operation of the movable disk 39, there is no intermediate water leakage. .

Since the lower surface of the fixed disk 44 applies the water pressure and the elastic force of the spring 45 in the same direction as the direction in which the water pressure is applied, the joint surface between the movable disk 39 and the fixed disk 44 is also provided. Even if the (rotation sliding surface) is worn, the joining surface is always kept in close contact,
Water tightness against abrasion can be sufficiently ensured. As described above, since the water pressure and the elastic force are applied to the joint surface between the movable disk 39 and the fixed disk 44, the movable disk 3
Although the turning resistance of the lever handle 9 is large, the lever handle 1
A leverage of 3 balances this with a slight operating force.

In the antifreeze faucet column a having the above structure, the lever handle 13 is located at the right rotation end in the drainage state shown in FIG. 1, but this operation is performed on the lot 11 integrated with the spindle 12. The rotation is transmitted to the integrated disk driver 24 by the spring pin 50, and the disk driver 24 rotates the movable disk 39 to the drain position through the rotation power transmission pin 23 hanging down from the lower surface thereof. In this state, the rotation positioning pin 21 hanging at the outer end of the lower surface is engaged with one end of an arc-shaped positioning groove 33 provided around the upper surface of the casing 34, and flows into the stopper box 5 from the water inlet 10. The water that flows is fixed disk 4
4 is blocked by the lower surface of the movable disk 39, so that water is stopped. Water in the upper water passage 1 from the movable disk 39 is removed from the communication hole 3 of the movable disk 39.
6 through the drain groove 43 of the fixed disk 44, through the drain hole 30 of the casing 34, through the communication space 19 of the plug box 5, and push up the ball valves 52 of the drain passages 51 disposed at two places on the left and right sides. It is drained to the outside. At this time, as shown in FIG. 2, air is sucked in from the intake valve 14 provided in the upper part of the water passage 1, and drainage becomes smooth.

Next, in order to change from the drained state shown in FIG. 1 to the water flowing state shown in FIG.
Is rotated to the left rotation end. The rotation end has an arc-shaped positioning groove provided around a peripheral edge of the upper surface of the casing 34 with a rotation positioning pin 21 hanging down at the outer end of the lower surface of the disk driver 24. 33. At this time, the movable disk 39 is moved by a pair of rotating power transmission pins 23 hanging from the lower surface of the disk driver 24.
Is rotated to the rotation end, and the communication hole 3 of the movable disc 39 is
Reference numeral 6 designates the phase of the water passage hole 42 of the fixed disk 44 coincident with that of the water passage hole 42. The drain groove 43 is completely blocked by the lower surface of the movable disk 39, and the water flowing from the water inlet 10 without intermediate leakage is Water hole 42 of fixed disk 44
The water is supplied from the water supply port 4 through the communication hole 36 of the movable disk 39 and the water passage 1 of the riser 2.
