Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an oil amount regulator whose main purpose is to maintain a constant amount of fuel supplied to a pot-type combustion appliance or the like.

Recent oil flow regulators of this type automatically cut off the supply of fuel to combustion appliances immediately in the event of an earthquake, and the driving force for this is now obtained through the operation of a seismic device. There is. However, conventional oil flow rate regulators are not necessarily suitable for abruptly stopping fuel leakage using such a seismic sensing device.

In other words, in conventional oil flow rate regulators, the flow rate adjustment function and the flow rate stop function are handled by one valve mechanism, so when the amount of outflow is large or small, the valve body is operated until the outflow is stopped. There is a difference in the amount of movement, and special consideration must be given to the force transmission mechanism between the seismic device and the seismic device to accommodate this difference. Another problem is that one way to increase the accuracy of oil flow control is to increase the stroke of the valve body, but the stroke of the valve body is too small to cut off the oil flow with a general seismic device. Considering this point, in order to perform the flow rate adjustment function and the flow rate stop function in one valve mechanism, it is necessary to suppress the stroke of the valve body even if it sacrifices the accuracy of the outflow amount to some extent. .

For example, Utility Model Application Publication No. 48-49630 discloses a device for controlling gas supply that includes two valves in series with the gas path, namely a control valve that can adjust the flow rate and a safety valve that shuts off the gas path when an earthquake is felt. It has been disclosed that when the safety valve is closed, the control valve is also automatically closed in conjunction with the closure of the safety valve. However, with this structure, the control valve is always locked in the closed state when the safety valve is closed, so it is not possible to control the gas supply only by the safety valve while the control valve is open. That is, for example, the safety valve is closed and the control valve is set slightly open, and a timer or the like is used to open the safety valve after a predetermined time to automatically supply the amount of gas determined by the control valve. 〓〓〓〓〓
I can't. Naturally, fuel gas is dangerous and automatic supply using a timer would not be performed, but when controlling fuel oil, such automatic supply cannot be performed, so it is recommended to use timer control for combustion equipment. This is extremely disadvantageous. As described above, the device disclosed in the above publication is not suitable as an oil amount regulator.

SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide an oil amount regulator that improves the accuracy of oil flow control, is suitable for cutting off oil flow using a seismic device, and has good operability.

Another object of the present invention is to provide an oil amount regulator that is convenient for controlling on/off of a combustion appliance using a timer or the like.

The oil amount regulator according to the present invention includes an oil amount regulator body having an oil flow path, an operating knob exposed to the outside of the oil amount regulator body, and an opening degree of a relatively upstream portion of the oil flow path that can be controlled by the above-mentioned operation. A movable oil volume control valve body that controls according to the operation of a knob, a movable oil volume stop valve body that can open and close the oil flow path at a relatively downstream portion, and a movable oil volume stop valve body that urges the oil volume stop valve body in the opening direction. a spring, an oil volume stop plate whose one end is fixed to the oil volume regulator body and whose other end is in contact with the opening direction end face of the oil volume stop valve body; a force transmission device that presses the oil amount stop plate in the closing direction of the oil amount stop valve body, one end of which is exposed to the outside of the oil amount regulator main body, and the other end of which is engaged with the oil amount stop plate;
It is characterized in that it includes a movable pin that can apply a pressing force to the oil amount stop plate in the closing direction of the oil amount stop valve body in response to an operation.

The present invention will be described below using an embodiment with reference to the drawings. The oil amount regulator main body 10 has an inlet 101 and an outlet 102. Inlet 1
01 is equipped with an inflow valve mechanism 11. This inflow valve mechanism 11 serves to open and close an oil inflow path by moving a float 12 disposed inside the main body 10 up and down according to the oil level, thereby successively replenishing the inside of the main body 10 with oil.

A temporary oil sump area 103 with an open upper surface is further formed in the main body 10, and this temporary oil sump area 1
03 is communicated with the outlet 102 of the main body 10 and the float chamber 104, thereby forming an oil outlet that connects the float chamber 104 to the temporary oil sump area 103 and the outlet 102. Then, in the hole on the lower surface of the temporary oil reservoir area 103, a fifth
As clearly shown in the figure, the valve seats 13 and 14 are arranged and fixed, respectively.
From above, the oil amount adjustment valve body 15 and the oil amount stop valve body 16
and slidably inserted.

The oil amount adjustment valve body 15 has a diagonal cut portion 15 at the lower end.
1, and when this diagonal cut portion 151 is pulled up until it corresponds to the valve seat 13, a gap is created between the diagonal cut portion 151 and the valve seat 13, and oil in the float chamber 104 temporarily flows into the oil sump area 103 through this gap. learn to allow yourself to do so. At this time, it will be confirmed that when the oil amount regulating valve body 15 is pulled up by a small amount, the gap is narrow and the amount of inflow is small, and when it is pulled up greatly, the gap becomes wider and the amount of inflow increases. That is, the oil amount regulating valve body 15 controls the opening degree of a relatively upstream portion of the oil outflow path.

On the other hand, the valve seat 14 into which the oil amount stop valve body 16 is inserted is cylindrical and has a valve hole 141 at the bottom. is now open and closed. Here, when the oil amount stop valve body 16 is in the lowered position, the valve hole 141 is closed, and when it is in the raised position, the valve hole 141 is opened to allow oil to flow out from the temporary oil sump area 103 to the outlet 102. That is, the oil amount stop valve body 16 can open and close the oil outflow path at a relatively downstream portion.

Now, a control valve body guide 17 having a circular cross section is fitted and fixed to the upper end of the oil amount control valve body 15, and is urged upward by a compression coil spring 18. On the other hand, the oil amount stop valve body 16 is urged in the opening direction, that is, upward, by a compression coil spring 19, and an oil made of an elastic material is fixed at one end to the main body 10 at its upper end. The free end of the stop plate 21 is brought into contact.

Then, attach the auxiliary plate 22 from above and screw 23.
It is fixed to the main body 10 with. At this time, the regulating valve body guide 17 is rotatably inserted into a hole provided in the auxiliary plate 22, and one piece 211 of the oil amount stop plate 21 is partially projected onto the auxiliary plate 22 through the square hole 221.

A semicircular cam 25 is attached to the lower surface of the auxiliary plate 22 with an adjustment screw 24 in a slightly inclined state, and a protrusion 251 formed on the lower surface of this cam 25 (see FIG. 5) ) control valve body guide 1
〓〓〓〓〓
The upward movement of the guide protrusion 171 provided at 7 is restricted. Note that the height of the cam 25 can be adjusted using an adjustment screw 24.

Further, on the upper surface of the auxiliary plate 22, an operating knob 26 is fitted to the upper end of the regulating valve body guide 17. At this time, the inward protrusion 261 of the operation knob 26
into the slit 172 of the regulating valve body guide 17. This operation knob 26 is further provided with an outward protrusion 262, and depending on the rotational position of the operation knob 26, the outward protrusion 262 pushes the lower piece 211 of the oil amount stop plate 21 downward, thereby causing the oil The amount stop plate 21 is strongly pressed against the end face in the opening direction, that is, the upper end, of the oil amount stop valve body 16.
That is, the outward protrusion 262 and the piece 211 are
It acts as a force transmission device for pressing the oil amount stop plate 21 toward the oil amount stop valve body 19 in response to the operation of the operation knob 26 in the direction of decreasing the opening degree.

Further, the upper open portion of the main body 10 is covered with a lid body 27. At this time, the upper part of the operating knob 26 is rotatably projected from the upper surface of the lid body 27. Then, install the snap spring 28.

Note that 29 is a hollow space provided in the main body 10, 31 is an air vent hole, and 32 is a pin provided so that the oil amount stop plate 21 can be operated from the outside. Pin 32 is the main body 1
One end is exposed to the outside of 0, and the other end is substantially engaged with the oil amount stop plate 21.

In the oil amount regulator having the above structure, the outward protrusion 262 of the operation knob 26 is now connected to the oil amount stop plate 21.
The position where this piece is pushed in corresponds to the piece 211, and the outflow amount is zero, and at this time, the control valve body guide 17
The guide protrusion 171 of the cam 25 corresponds to the lowest position of the protrusion 251 of the cam 25. In this way, when the operating knob 26 is in the position where the amount of outflow is zero, the oil amount adjustment valve body 15 and the oil amount stop valve body 16 are in the lowered position and the valve hole 141 is closed. It will not leak out.

Next, by slightly rotating the operating knob 26, the outward protrusion 262 will come off the oil level stop plate 21.
The oil amount stop valve body 16 is moved upward by the spring 19 to a position where the valve hole 141 of the valve seat 14 is opened. At the same time, the control valve body guide 17 rotates,
The guide protrusion 171 of it is the protrusion 251 of the cam 25.
slide along. Here, since the cam 25 is inclined as described above, the oil amount regulating valve body 15 and the regulating valve body guide 17 are moved by the spring 18 according to the inclination.
It is moved upward by. When the oil amount adjusting valve body 15 rotates and rises and its diagonal cut portion 151 corresponds to the valve seat 13, a gap is created there, and the oil in the float chamber 104 temporarily passes through the oil sump area 103 and flows out to the outlet 102. It is leaked from.

The amount of oil flowing out is controlled according to the rotation angle of the operating knob 26. That is, as the rotation angle of the operating knob 26 increases, the amount of outflow decreases, and as the rotation angle increases, the amount of outflow increases. Also, the operation knob 26
When it returns to the above-mentioned position of zero outflow, the outward protrusion 262 pushes the piece 211 of the oil stop plate 21 downward, so the oil stop plate 21 bends downward and the flow stop valve body 16 is pressed down, thereby completely blocking oil spillage. Also at this time,
Although the operating knob 26 is only rotated, the oil amount adjustment valve body 15 moves up and down while rotating, and this, together with the fact that it has the diagonal cut portion 151 at the lower end, prevents it from becoming clogged with dirt. It can prevent poor oil flow control.

Now, when an earthquake occurs, the pin 32 is pressed down by a seismic device (not shown) (Fig. 4 shows pin 32).
2 indicates a lowered state). Then pin 3
Since the oil amount stop plate 21 is pushed downward at the lower end of the oil amount stop valve 21, the oil amount stop valve body 16 descends and closes the valve hole 141 of the valve seat 14. Thus, even under normal oil spill conditions, when an earthquake occurs, the oil spill is quickly shut off. Note that at this time, the oil amount regulating valve body 15 remains in the valve open position, so the temporary oil sump area 10
The oil level in float chamber 104 rises to a level equivalent to the oil level in float chamber 104.

In addition, when a power outage occurs during a normal oil spill, a power outage sensing device (not shown) is used to rotate the operating knob 26 to lower the oil amount regulating valve body 15 and throttle the valve, thereby reducing the amount of oil spilled. Minutely. At this time, of course, the oil amount stop valve body 16 is in the open position.

Further, according to the oil amount regulator having this structure, the oil amount adjustment valve body 15 is connected to the oil amount stop valve body 15 whether the oil amount stop valve body 16 opens or closes the oil flow path. Since it is designed to be able to be driven without being restricted, it is convenient when controlling combustion appliances on and off using a timer or the like. That is, push in the pin 32 to stop the oil amount stop valve body 16.
With the outflow path being set in a closed state, the oil amount regulating valve body 15 is set in a state where the oil outflow path is slightly open, and then the push-in of the pin 32 is released after a certain period of time has elapsed using a timer or the like. Then, it is preferable to open the oil outflow path using the oil amount stop valve body 16, thereby starting the supply of fuel oil to the combustion appliance. In this case, the amount of oil supplied to the combustion appliance is a constant value determined by the state of the oil amount regulating valve body 15, so that combustion of a desired magnitude can be automatically obtained.

As described above using the embodiments, according to the present invention, the stroke of the oil volume control valve body for adjusting the flow rate is increased to improve the precision of flow rate control, and the oil volume is stopped for stopping the flow rate. The stroke of the valve body can be made small and constant regardless of the amount of outflow, making it suitable for cutting off the flow by a seismic device, and furthermore, both valve bodies can be operated with one operating knob. It has good operability, and as is clear from the explanation using the above embodiment, it is convenient when controlling combustion appliances on and off using a timer or the like.
Therefore, a very excellent oil amount regulator is obtained.

Although the above description has been made using a specific embodiment, the present invention is not limited thereto, and of course includes various modifications.
