Sealing ring.
By using technical solutions of the utility model, superposition axial seal on the basis of flat seal, during closed electromagnetic valve, as
Fruit has granule foreign to enter the sealing station between diaphragm assembly and valve seat, and makes the situation that diaphragm assembly end face seal lost efficacy
Under, sealing ring, by diaphragm assembly upper and lower cavity pressure differential effect, is forced into the endoporus of valve seat, complete independently axial seal.Therefore,
Play dual sealing functions simultaneously, thus be effectively increased sealing property.
This utility model is arranged further: the inwall at endoporus top of described valve seat and the top end wall of valve seat pass through circular arc wall
Transition.
By using technical solutions of the utility model, sealing ring more can smoothly enter in valve seat along circular arc wall
Hole is to realize axial seal.
This utility model is arranged further: be provided with the positioning boss positioning sealing ring on described extending column.
By using technical solutions of the utility model, by positioning boss, sealing ring is entered location, improve stability.
This utility model is arranged further: arrange oriented relative Electromagnetic Control mechanism opposite side direction depression in described valve body
Receive dirty cavity.
By using technical solutions of the utility model, during water purification machine controlling the water circulation, solenoid valves, diaphragm assembly lift is little, main
Runner half-open position, discharge is little, and the impulse force of water is little, and the fine particle impurity in water falls and receiving dirty cavity；When water purification machine rinses,
Solenoid valves, diaphragm lift is big, sprue full-gear, and discharge is big, and the impulse force of water is big, by miscellaneous for the granule received in dirty cavity
Matter is gone out.
This utility model is arranged further: described in receive dirty cavity and be placed in the inner opposite end of described water inlet flow channel, and described
Dirty cavity of receiving caves in relative to Electromagnetic Control mechanism opposite side direction to described water inlet flow channel.
By using technical solutions of the utility model, during water purification machine controlling the water circulation, granule foreign be more prone to be deposited in receive dirty recessed
Intracavity；And during water purification machine flushing, be more prone to go out the granule foreign received in dirty cavity.

Detailed description of the invention
See accompanying drawing 1-accompanying drawing 4, dual-seal electromagnetic valve disclosed in this utility model, include Electromagnetic Control mechanism 1, valve
Body 2 and diaphragm assembly 3, it is preferred that diaphragm assembly 3 includes diaphragm 301 and support 302 thereof, and described valve body 2 is provided with into water
Runner 201 and outlet passage 202, be provided with valve seat 203, described barrier film group at water inlet flow channel 201 and outlet passage 202 joining place
Be provided with inlet through hole 31 and water outlet through hole 32 on part 3, the expansion link of Electromagnetic Control mechanism 1 coordinate with water outlet through hole 32 realization every
Closedown and conducting between membrane module 3 with valve seat 203 coordinate, and corresponding water outlet through hole 32 position of described diaphragm assembly 3 arranges oriented
The extending column 33 that valve seat 203 direction extends, described extending column 33 is arranged with the sealing ring 4 that the endoporus with valve seat 203 matches.
By using technical solutions of the utility model, superposition axial seal on the basis of flat seal, during closed electromagnetic valve, if there being granule
Impurity enters the sealing station between diaphragm assembly 3 and valve seat 203, and in the case of diaphragm assembly 3 end face seal was lost efficacy,
Sealing ring 4, by diaphragm assembly 3 upper and lower cavity pressure differential effect, is forced into the endoporus of valve seat 203, complete independently axial seal.Cause
This, play dual sealing functions simultaneously, thus be effectively increased sealing property.The present embodiment is preferred, and inlet through hole 31 also sets up
