Abstract

PROBLEM TO BE SOLVED: To surely locate a control valve disk at the opening/closing position by moving a control rod to advance/retract the control valve disk by a lever oscillating around a shaft, and urging the lever by an urging member so as to be stopped at two positions, i.e., the rod retracting position and at the rod advancing position. SOLUTION: When the right side of a lever 36 is pressed in, a control rod 30 is urged by the lever 36, and a control valve disk 32 is seated on a seat part 28 of a diaphragm 22 to close a small hole 26. In this condition, the water pressure in an inflow passage 10 is transmitted to a control chamber 18 through a small hole 24, the inflow passage 10 is shut off from an outflow passage 12, and a valve is in a stopped condition. When the left side of the lever 36 is pressed in, a locking claw 50 pulls the control rod 30 upward, and the control valve disk 32 is separated from the seat part 28. Because the control chamber 18 is communicated with the outflow passage 12 through the small hole 26, the diaphragm 22 is separated from the seat part 20 by the water pressure from the inflow passage 10, water from the inflow passage 10 flows through the outflow passage 12, and the valve is in a water-spouting condition.

[0012]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a cross-sectional view of a manual diaphragm valve according to an embodiment, and FIG. 2 is a cross-sectional view showing a water discharge state of the valve.

A control room 18 is provided by mounting a housing cap 16 on a housing 14 having an inflow channel 10 and an outflow channel 12. In addition, outflow channel 1
The end inside the housing 2 is an annular seat portion 20 protruding toward the control room 18. This seat part 2
The diaphragm 22 is provided so as to be seated at zero. The diaphragm 22 has a control room 18 and an inflow path 1.
0 and a second small hole 26 communicating between the control room 18 and the outflow passage 12.
On the control room 18 side of the diaphragm 22, a sheet portion 28 is formed by the edge of the second small hole 26 protruding toward the control room 18.

A control rod 30 is inserted into the control chamber 18 through the housing cap 16, and a control valve 32 is provided at an end of the control rod 30 inside the control chamber 18. Note that a seal ring 3 for sealing between the inner peripheral surface of the rod and the through hole is provided on the inner peripheral surface of the insertion hole of the control rod 30 provided in the housing cap 16.
4 are arranged.

In order to move the control rod 30 forward and backward,
A lever 36 is swingably supported by the housing cap 16 via a spindle support 38 and a spindle 40. The housing cap 16 has a spring support 42 protruding from one side of a spindle support 38, and the lever 3
The hook 44 is provided on the opposite side of the back surface of the support support 40 from the spring support 42 with the support shaft 40 interposed therebetween. A tension coil spring 46 is bridged between the spring support 42 and the hook 44.

As shown in FIG. 1, the position of the hook 44 is
When it is closer to the housing cap 16 than 0, the right side of the lever 36 in FIG. 1 is urged downward. Also, the second
As shown, when the hook 44 is farther from the housing cap 16 than the support shaft 40, the left side of the lever 36 is urged downward. In FIG. 2, the left side of the lever 36 is in contact with a stopper 48 provided on the housing cap 16.

On the back surface of the lever 36, a locking claw 50 for lifting the control rod 30 is provided.

In the manual diaphragm valve constructed as described above, when the right side of the lever 36 is pushed in as shown in FIG. 1, the control rod 30 is urged downward by the lever 36 in FIG. The valve element 32 is seated on the seat portion 28 of the diaphragm 22, and the second small hole 26 is closed. In this state, the water pressure in the inflow passage 10 is transmitted to the control room 18 via the first small holes 24, and the diaphragm 22 is brought into close contact with the seat portion 20. This allows
The inflow path 10 and the outflow path 12 are shut off, and the valve is in a water stop state.

When the left side of the lever 36 is pushed in, the locking claw 5
0 raises the control rod 30, and the control valve body 32 separates from the seat portion 28. Then, the inside of the control room 18 becomes the second
Therefore, the water pressure in the control room 18 becomes lower than that of the inflow passage 10 because of communication with the outflow passage 12 through the small hole 26. As a result, the diaphragm 22 moves in a direction away from the seat portion 20 due to the water pressure from the inflow path 10, and the inflow path 10 is in direct communication with the outflow path 12. Then, the water from the inflow path 10 flows out through the outflow path 12, and the valve is in a water discharge state.

In the water discharge state shown in FIG. 2, when the right side of the lever 36 is pushed again, the diaphragm 22 is moved to the seat portion 20 while the control valve 32 closes the second small hole 26.
(In this case, water flows into the control room 18 via the first small holes 24), and the diaphragm 22 is seated on the seat portion 20 in FIG. As shown in the water stoppage state.

As described above, in the manual diaphragm valve shown in FIGS. 1 and 2, the valve can be opened and closed by pressing the end of the lever 36.

FIG. 3 is a sectional view of a manual diaphragm valve according to another embodiment, showing a closed state. FIG. 4 is a sectional view showing a state of water discharge of the valve of FIG.

In this embodiment, the housing 5
A bypass passage 58 is provided in the housing 4 and the housing cap 56, and a partition wall 60 is provided between the bypass passage 58 and the control room 18. The partition wall 60 is provided with a second small hole 62, and the control valve body 32 is provided so as to close the second small hole 62. The bypass passage 58 is provided so as to communicate the second small hole 62 with the outflow passage 12. The other configuration is the same as that of the valve in FIGS. 1 and 2, and the same parts are denoted by the same reference numerals and description thereof will be omitted.

In the manual diaphragm valve shown in FIGS. 3 and 4 as well, water can be discharged and water can be stopped by pressing the left or right side of the lever 36. In the state shown in FIG. 3, the right side of the lever 36 is pushed, and the control valve body 32 closes the second small hole 62. In this state, the water pressure in the inflow passage 10 is transmitted to the control room 18 through the first small holes 24, and the diaphragm 22 is pressed against the seat portion 20 by the water pressure to stop water. In addition, the control valve body 32 has a lever 36.
Is in close contact with the second small hole 62 by the urging force of the spring 46.

In the state shown in FIG. 3, when the left side of the lever 36 is pressed, the pressing force applied to the control valve body 32 is released, and the water pressure from the control chamber 18 causes the control valve body 32 to move to the second small position. It separates from the hole 62. As a result, the control room 18 communicates with the outflow passage 12 via the bypass passage 58, and the water pressure in the control room 18 decreases. As a result, the diaphragm 22 is pushed up by the water pressure from the inflow path 10 and separates from the seat portion 20. And the inflow channel 10
From the water directly flows out to the outflow channel 12, and the valve is in a water discharging state. When the diaphragm 22 separates from the seat portion 20, the water in the control room 18 is filled with the second small holes 62.
And, it flows out to the outflow channel 12 through the bypass channel 58.

In the water discharge state shown in FIG. 4, when the right side of the lever 36 is pushed in, the second small hole 62 is closed by the control valve body 32. Then, the diaphragm 22 gradually moves toward the seat portion 20 by the restoring force of the diaphragm 22. At this time, water gradually flows into the control room 18 through the first small holes 24. Finally, the diaphragm 22 comes into close contact with the sheet portion 20 and returns to the water-stop state shown in FIG.
