Summary of the invention
The deficiency existed for prior art, it is an object of the invention to provide a kind of simple in construction, is effectively improved the dual-seal electromagnetic valve of sealing property.
For achieving the above object, the technical scheme is that a kind of dual-seal electromagnetic valve, include Electromagnetic Control mechanism, valve body and diaphragm assembly, water inlet flow channel and outlet passage it is provided with on described valve body, water inlet flow channel and outlet passage joining place are provided with valve seat, inlet through hole and water outlet through hole it is provided with on described diaphragm assembly, the expansion link of Electromagnetic Control mechanism coordinates the cut out realizing between diaphragm assembly with valve seat and conducting to coordinate with water outlet through hole, described diaphragm assembly correspondence water outlet lead to the hole site arranges the extending column that oriented valve seat direction extends, the sealing ring that the endoporus with valve seat matches it is arranged with on described extending column.
By using technical solution of the present invention, superposition axial seal on the basis of flat seal, during closed electromagnetic valve, if there being granule foreign to enter the sealing station between diaphragm assembly and valve seat, and in the case of diaphragm assembly end face seal was lost efficacy, 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.
The present invention is arranged further: the inwall at the endoporus top of described valve seat and the top end wall of valve seat are by circular arc wall transition.
By using technical solution of the present invention, sealing ring can more smoothly enter the endoporus of valve seat to realize axial seal along circular arc wall.
The present invention is arranged further: be provided with the positioning boss positioning sealing ring on described extending column.
By using technical solution of the present invention, by positioning boss, sealing ring is entered location, improve stability.
The present invention is arranged further: arrange the dirty cavity of receiving of oriented relative Electromagnetic Control mechanism opposite side direction depression in described valve body.
By using technical solution of the present invention, during water purification machine controlling the water circulation, solenoid valves, diaphragm assembly lift is little, sprue half-open position, and 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, is gone out by the granule foreign received in dirty cavity.
The present invention is arranged further: described in receive dirty cavity and be placed in the inner opposite end of described water inlet flow channel, and described in receive dirty cavity and cave in relative to Electromagnetic Control mechanism opposite side direction to described water inlet flow channel.
By using technical solution of the present invention, during water purification machine controlling the water circulation, granule foreign is more prone to be deposited in be received in dirty cavity；And during water purification machine flushing, be more prone to go out the granule foreign received in dirty cavity.
