よって電磁弁部Ａは止水状態を維持するものである。The solenoid valve portion A is of a type called a pilot system, and has a feature that high pressure and large flow rate can be controlled. Fifth
The state shown in the figure shows a water stop state in which the solenoid valve portion A is off. A pilot hole 7a is formed in the center of the center plate 7 of the solenoid valve portion A, and a bleed hole 7b is formed in the peripheral portion. The pilot hole 7a is closed by the plunger 20 being pushed by the spring force of the spring 26. ing. The recess of the lid 8 of the solenoid valve portion A is filled with tap water from the water supply port 31 which has flowed through the bleed hole 7b in a water-stop state. In this state, the diaphragm 12 is pressed against the water stop projection 1a by a differential pressure between the high water supply pressure of the water supply section and the low pressure in the water stop projection 1a, so that the electromagnetic valve portion A maintains the water stop state.

る。Next, when the coil 9 of the solenoid valve section A is excited, the plunger 20 of the solenoid valve section A is sucked leftward in FIG. 5 to open the pilot hole 7a, and the pilot hole diameter is larger than the bleed hole diameter. The tap water in the recess of the lid 8 of the valve portion A gradually decreases because the amount of tap water flowing through the pilot hole 7a is larger than the amount of water flowing into the lid 8 through the bleed hole 7b. Then, the diaphragm 12 is pushed to the left by the water pressure in the channel g, and the valve seat As of the solenoid valve portion A is opened to enter a water-permeable state. When the electromagnetic valve unit A is water flow state of water waterways g reaches communicating waterway F 1 overcame water barrier projection 1a.

となる。Next, when the excitation of the coil 9 of the solenoid valve section A is stopped, the plunger 20 which has been sucked up to now is pushed back rightward in FIG. 5 by the spring 26, and the pilot hole 7a is closed. As a result, water starts to flow from the bleed hole 7b into the concave portion of the lid 8 of the solenoid valve portion A, and when the water becomes full, the diaphragm 12 is pushed rightward by water pressure and comes into contact with the water stop protrusion 1a. The water passage is closed, and the electromagnetic valve portion A is in a water stop state.

る。As shown in FIGS. 4 and 5, the structure of the pressure reducing valve portion B is such that center plates 19 are mounted on both sides of the diaphragm 11 of the pressure reducing valve portion B, and an inner plug 18 is inserted into a central hole of both of them. The nut 11 connects the diaphragm 11 of the pressure reducing valve section B to the inner plug 18. The O-ring 14 is inserted into the lower part of the inner plug 18, and the inner plug support lid 4 with the O-ring 16 inserted therein is screwed in from below the base 1, and the inner plug 18 is inserted into the inner plug support lid. 4 so as to be slidable. A T-shaped communication hole 18a is provided at the center of the inner plug 18, and the secondary pressure on the upper portion of the inner plug 18 is transmitted through the communication hole 18a to the lower portion of the inner plug 18, the O-ring 14, and the inner plug. It is led to the space 28 formed by the support lid 4 and the pressure acting on the inner plug 18 is balanced between the upper part and the lower part, so that the fluctuation of the secondary pressure when the primary pressure changes is suppressed low. on the other hand,
A lid 2 as a component 2b for fixing the diaphragm 11 is installed on the upper side of the diaphragm 11.
Is formed in series with a constituent member 2d of the vacuum break valve portion D described later, and also serves as a cover of the vacuum break valve D. This lid 2
Is provided with a cylindrical projection 2e, and the lower end of the adjustment spring 25 of the pressure reducing valve section B is formed by a center plate 19.
The upper end thereof is held by a depressurizing adjustment knob 5, and by turning the depressurizing adjusting knob 5, the set value of the secondary pressure can be changed by changing the spring force. The depressurization adjusting knob 5 has a concave cylindrical shape, has a screw on the inner circumferential surface, and is fitted with a screw on the outer circumferential surface of the cylindrical projection 2e of the lid 2. For this reason, in the event that the diaphragm 11 of the pressure reducing valve section B is broken, the bottom of the depressurization adjusting knob 5 receives the water spouting vigorously upward and kills the water and prevents the water leakage prevention wall 2a from having a cylindrical projection. Water around the toilet is prevented by providing around 2e.

Is located inside the water leakage prevention wall 2a rising from the constituent members 2b and 2d such as lids, so that even if the diaphragm 11 is unexpectedly torn and the tap water is discharged from the inside of the pressure reducing valve portion B, the tap water can be guided downward. The wall 5a is guided to flow down inside the water leakage prevention wall 2a, and the function of the conventional lid H is given to the decompression adjusting knob 5 to reduce the number of lids.

るものである。Explaining the pressure regulation principle of the pressure reducing valve portion B, the force for pushing the diaphragm 11 of the pressure reducing valve portion B upward by the secondary pressure (P 2 ) and the force for pushing the diaphragm 11 downward by the adjusting spring 25 are balanced. The flow path formed by the inner plug flange 18b of the inner plug 18 fixed to the diaphragm 11 of the pressure reducing valve portion B and the pressure reducing port 1b as the valve seat portion Bs provided on the base 1 has a certain opening degree. If the primary pressure (P 1 ) increases for some reason, the secondary pressure (P 2 ) also increases due to the increase in the primary pressure (P 1 ). As a result, the force for pushing the diaphragm 11 upward increases, and the inner plug 18 moves upward. As a result, the flow path between the inner plug collar 18b is narrowed, the flow path loss increases, the value of the secondary pressure (P 2 ) decreases, and the original value is maintained.

Since the communication water passages formed on the individual bases and communicating between the valve portions are formed integrally with the base inside the base, the communication water passages communicating between the respective valve portions are provided inside the base. It is formed integrally with the base and eliminates the need for piping between the valve parts, but does not require a bottom plate to form a communicating water channel. Further, there is an advantage that the number of parts can be significantly reduced, the workability of assembling can be enhanced, and sufficient sealing performance can be secured without the need for a large number of screws.
