Cross screw mutually to fix, valve body runs through solenoid valve body, and the top of valve body is provided with back-moving spring, and sealing gasket is arranged on fixed cover
Between fixed lower cover, fixed between fixed cover and fixed lower cover by screw, fixed lower cover includes fixed lower cover body, entered
Liquid/gas passage and go out liquid/gas passage, enter liquid/gas passage and go out liquid/gas passage and be fixedly connected respectively with fixation lower cover body, Gu
Fix in lid body and be provided with accommodating cavity, the liquid/gas mouth that goes out for entering liquid/gas passage is stretched into accommodating cavity, enter liquid/gas passage and go out liquid/
Gas passage is connected by accommodating cavity.
After energization, valve body is descending in the presence of electromagnetic force, promote sealing gasket downwards until block in accommodating cavity feed liquor/
Gas passage goes out liquid/gas mouth, realizes sealing and bears the effect of pressure；When power is off, electromagnetic force disappears, and valve body is by resetting bullet
The effect of spring is up walked, while sealing gasket leaves the air inlet of ventilation lower cover together with valve body, plays pressure release effect.
Compared with prior art, valve body does not contact with liquid or gas, not the temperature of liquid body or gas, corrosivity and pure
Cleanliness influences, and greatly expand pressure solenoid valve uses field, use range, and improve pressure solenoid valve uses the longevity
Life.
Of the invention further to improve, described sealing gasket is structure as a whole, including center pad, extension and outer rim, center
Pad is connected by extension with outer rim, and by the outer fringe seal of sealing gasket between fixed cover and fixed lower cover, center pads
Dredged referring now to the stifled of liquid/gas mouth that go out for entering liquid/gas passage in accommodating cavity；So it is achieved that a pad uses, extension is set
The harmomegathus of center pad is avoided, improves the overall service life of sealing gasket.
Of the invention further to improve, the outer rim of described sealing gasket is provided with flange, circular hole is provided with inside center pad, in circle
The top in hole is fixedly installed annular protrusion, and the outer wall of accommodating cavity is arranged on flange bottom, and the bottom of valve body is patty valve
Head, the top of patty valve head are provided with groove, and patty valve head is sleeved in the circular hole of center pad, and annular protrusion is fastened on recessed
In groove；So, center pad is driven to block the response for going out liquid/gas mouth, shortening magnetic valve into liquid/gas passage when valve body is descending immediately
Time.
A kind of pressure solenoid valve proposed by the invention, valve body do not contact with liquid or gas, not liquid body or gas
Temperature, corrosivity and degree of purity influence, and greatly expand pressure solenoid valve uses field and use range, improves pressure
The service life of magnetic valve.

Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out clear, complete
Site preparation describes, it is clear that described embodiment is only part of the embodiment of the present invention, rather than whole embodiments.It is based on
Embodiment in the present invention, those of ordinary skill in the art are obtained every other under the premise of creative work is not made
Embodiment, belong to the scope of protection of the invention.
Referring to accompanying drawing 1-7, a kind of pressure solenoid valve, including solenoid valve body 1, valve body 2, fixed cover 3, the and of sealing gasket 4
Fixed lower cover 5, two sides of solenoid valve body 1, two sides of fixed cover 3 have some mounting holes, magnetic valve
Body 1 is arranged in fixed cover 3 and fixed by the phase of screw 6, and valve body 2 runs through solenoid valve body 1, and the top of valve body 2 is set
There is back-moving spring 7, sealing gasket 4 is arranged between fixed cover 3 and fixed lower cover 5, is passed through between fixed cover 3 and fixed lower cover 5
Screw 6 is fixed, and fixed lower cover 5 includes fixed lower cover body, enters liquid/gas passage 51 and go out liquid/gas passage 52, enters liquid/gas passage
