When the utility model is used, it is necessary to the control machine opened and closed in valve body and with controllable relief hole 26
Structure is installed together, which can be hand-operated valve, or solenoid valve, in the present embodiment, by taking solenoid valve as an example
It illustrates, as shown in Figures 4 and 5, valve body 7 is equipped with water inlet 71 and water outlet 72, is formed between water inlet 71 and water outlet 72
There is via 73, the waterway controlling valve component of the utility model is mounted in valve body 7 and on via 73, the diaphragm body 1
Lower end 12 and the upper surface of via 73 it is in sealing contact, limited step 74 is equipped in the cavity of valve body 7,3 /V of diaphragm seat exists
So that the waterway controlling valve component of the utility model is fixedly mounted in valve body 7 on limited step 74, solenoid valve 8 is arranged on pressure
2 upper surface of lid, the water outlet of deflector hole 21 are connected by solenoid valve with the water inlet end sealing of relief hole 26, and the solenoid valve 8 is set
There are dynamic iron core and the seal head being arranged in dynamic iron core 81, the seal head 81 is used to seal relief hole 26.
The course of work：The lower end 12 of diaphragm body 1 is close so as to be played to water inlet 71 by being sealed to via 73
Envelope acts on, and water pressure balance cavity 6 can be filled full water by water by the intake tunnel of diaphragm body 1, when solenoid valve 8 is opened, electromagnetism
Valve plunger rises, the disengaging relief hole 26 of seal head 81, and the water in water pressure balance cavity 6 passes through the deflector hole 21 on diaphragm gland 2
Relief hole 26 and pressure release water stream channel 22 are flowed into, the flow channels 31 of diaphragm seat 3 are then flowed by pressure release water stream channel 22, most
The water outlet 72 of valve body 7 is flowed to by flow channels 31 afterwards, at this point, since the pressure of water pressure balance cavity 6 is drained decompression, hydraulic pressure
The pressure of counter balance pocket 6 and the intake pressure of water inlet 71 form an apparent pressure differential, and the pressure in water pressure balance cavity 6 is small
In the intake pressure of water inlet 71, under the promotion of intake pressure, diaphragm body 1 moves up, the lower end 12 of diaphragm body 1
Depart from via 73 so that the water inlet 71 of valve body 7 is connected with water outlet 72, and water route is opened completely, as shown in Figure 5；Work as electromagnetism
When valve 8 is closed, movable iron core of electromagnetic valve declines, and seal head 81 blocks relief hole 26, and same time, sub-fraction water passes through diaphragm
The intake tunnel of body 1 flows to the water inlet of water pressure balance cavity 6 and is pressurized, and the water in water pressure balance cavity 6 is nowhere drained, water pressure balance cavity 6
Interior pressure gradually increases, and diaphragm body 1 is gradually promoted to move down up to the lower end 12 of diaphragm body 1 closing via 73,
Realize that water route is closed, as shown in Figure 4.
The utility model prevents since the intake pressure of water inlet is to diaphragm ontological existence impetus or has slowed down diaphragm
Body moves down the speed of closing, effectively reduces or avoid diaphragm body because water hammer caused by quick closedown vibrates；Diaphragm
Diaphragm seat is arranged with outside body, protection and fixation are played to diaphragm body, can so improve the resistance to pressure energy of diaphragm body
Power, and it is avoided that the phenomenon that displacement of diaphragm body occurs；Diaphragm body is integrally formed the structure of part, reduces leak risk,
Its anti-pressure ability is increased by stent, centre is also avoided due to diaphragm body by the way of axle sleeve since long-time switchs water
When friction the problem of causing service life short.
Although specifically showing and describing the utility model with reference to preferred embodiment, those skilled in the art should
This is understood, in the spirit and scope for not departing from the utility model that the appended claims are limited, in form and details
On the utility model can be made a variety of changes, be the scope of protection of the utility model.
