に大きな力が必要になりそれだけ使い勝手が悪くなる。In the conventional valve device employed in such a toilet flush piping facility, the auxiliary valve element 11 is always closed by the water pressure in the pressure chamber 9 of the valve body 5 (the auxiliary valve). It is urged in the direction in which it abuts against the seat 10.
Therefore, the higher the water pressure in the pressure chamber 9, the greater the force required to push the push button 14 and tilt the auxiliary valve body 11. However, the tap water pressure fluctuates, and when it is low, it is about 0.7 kg / cm2, which means that it can be operated conveniently with a small force, but when it is high (especially at night), it can reach 7 kg / cm2. It requires a lot of power to operate, and the usability becomes worse.

ある。By the way, in the conventional valve device adopted in the toilet flushing plumbing system, an operation mechanism using a rotating cam using a battery as a power source is adopted instead of the push button 14 described in FIG. Some of them are uneconomical because such a large amount of power consumption is required when a large force is required for the operation of tilting the auxiliary valve body 11.

により、流体出口通路へは水が流れ出なくなる。In the valve device according to the first aspect of the present invention, the auxiliary valve element is brought into contact with the auxiliary valve seat by the force of the spring, and the contact surface is brought into contact with the valve seat due to the fluid pressure of the pressure chamber or the weight of the valve body. In the state where the pressure is applied, the pressure of the pressure chamber is applied to the auxiliary valve body through the through passage, and the auxiliary valve body receives a force in the direction of separating from the auxiliary valve seat. Therefore, by making the force of the spring slightly larger than the water pressure received by the auxiliary valve body at this time, water does not flow out to the fluid outlet passage.

出口通路に水が流れ出る。When the other end of the valve rod is pushed in from this state, the auxiliary valve body separates from the auxiliary valve seat against the force of the spring, and accordingly, the water in the pressure chamber passes through the through passage and the fluid outlet passage. Flow to. At this time, since the auxiliary valve body receives the water pressure of the pressure chamber, the force for pushing the other end of the valve rod can be reduced by the amount corresponding to the water pressure applied to the auxiliary valve body.
Further, the amount of water flowing into the fluid outlet passage at this time is smaller than the amount of water flowing from the fluid chamber into the pressure chamber through the pores.
Therefore, the water pressure in the pressure chamber becomes lower than the water pressure in the fluid chamber, and due to the water pressure difference between the two chambers, the valve body rises against the force of the spring, the contact surface separates from the valve seat, and the fluid outlet directly from the fluid chamber. Water flows into the passage.

When the through passage is blocked in this way, the fluid continues to flow from the fluid chamber to the fluid outlet passage immediately after the blocking, so that water flows from the fluid chamber to the pressure chamber through the pores, and The contact pressure comes into contact with the valve seat depending on whether the water pressure becomes higher than the water pressure in the fluid chamber and the valve body lowers due to the water pressure difference between the chambers or the valve body lowers due to the weight of the valve body. This blocks the fluid outlet passage.

Away from the seat, the water in the pressure chamber accordingly flows out through the through passage into the fluid outlet passage. At this time, since the auxiliary valve body receives the water pressure of the pressure chamber, part of the force pushing the other end of the valve rod is covered by the water pressure of the pressure chamber.

It flows into the aisle. At this time, since the auxiliary valve body receives the water pressure of the pressure chamber, part of the force pushing the other end of the valve rod is covered by the water pressure of the pressure chamber.

用を説明する。Next, the valve device having the above-mentioned structure in which the force of the spring 37 is set to be a little larger than the force of pushing the auxiliary valve body 35 downward by the pressure of the pressure chamber 31 is installed so that its axis is vertical. The operation when used in a toilet flush piping system will be described.

る。When the rotary cam 51 is set to the non-actuated position as shown in FIG. 1, the spring 3 is moved as described above.
In the state where the auxiliary valve element 35 is in contact with the auxiliary valve seat 33 by the force of 7 and the contact surface 28 of the valve body 26 is in contact with the valve seat 24,
Water does not flow into the fluid outlet passage 23. Not in use.

２３に水が流れ出る。使用状態である。When the eccentric shaft 52 is driven to rotate the rotary cam 51 to the operating position from the non-use state, the rotary cam 51 causes the valve rod 34 to rotate in the initial stage as shown in FIG.
Since the other end portion 34a of the valve is pushed downward against the force of the spring 34, the auxiliary valve body 35 separates from the auxiliary valve seat 33 against the force of the spring 34, and accordingly the pressure chamber 31
Water flows out through the through passage 32 into the fluid outlet passage 23. When the rotary cam 51 pushes the valve rod 34 downward, the water pressure of the pressure chamber 31 is applied to the auxiliary valve body 35, so the force pushing the valve rod 34 by the rotary cam 51 is applied to the water pressure applied to the auxiliary valve body 35. Correspondingly less power is required, and the power consumption required to operate the rotary cam 51 is correspondingly lower. In addition, the fluid outlet passage 23 at this time
The amount of water flowing into the pressure chamber 31 is smaller than the amount of water flowing into the pressure chamber 31 from the fluid chamber 30 through the pore 7. Therefore, the pressure chamber 3
The water pressure of 1 becomes lower than the water pressure of the fluid chamber 30. Therefore, as shown in FIG. 3, the valve body 26 rises against the force of the spring 37 due to the water pressure difference between the chambers 31 and 30, the contact surface 28 separates from the valve seat 24, and the fluid outlet passage 23 directly from the fluid chamber 30. Water runs out to. It is in use.

使用状態である。When the eccentric shaft 52 is driven and the rotary cam 51 is rotated to the non-actuated position from this state of use, the pushing force on the valve rod 34 is released, so that the force of the spring 37 as shown in FIG. 35 abuts against the auxiliary valve seat 33 against the water pressure in the pressure chamber 31 and shuts off the through passage 32. When the through passage 32 is blocked in this way, the fluid continues to flow from the fluid chamber 30 to the fluid outlet passage 23 immediately after the blocking, so that water is flown from the fluid chamber 30 to the pressure chamber 31 through the pores 29. By flowing in, the water pressure in the pressure chamber 31 becomes higher than the water pressure in the fluid chamber 30, and the valve body 26 descends due to the water pressure difference between the two chambers 30 and 31, or due to the weight of the valve body 26. Contacts the valve seat 24. As a result, the fluid outlet passage 23 is shut off. Not in use.
