The sidewall of guide sleeve can notch carry out spacing to buffer gasket, prevents buffer gasket in collision process from departing from static iron core.
As preferably, described dynamic iron core is provided with the mounting hole for settling described Returnning spring towards the side of static iron core, the side of static iron core has valve port rubber dorsad.
Mounting hole can provide support to spring, ensures the stable operation of spring.
As preferably, also comprise chamber cover, described valve body is multiple, each valve body is all fixed on the sidewall of described chamber cover, and the dynamic iron core of each valve body stretches in the cover of described chamber through the sidewall that described chamber is overlapped, the sidewall of described chamber cover also seals and is fixed with some valve nozzles, each valve nozzle include the valve port end that coordinates with corresponding valve port rubber phase and be positioned at chamber overlap outside outlet side.
By the design that chamber is overlapped, multiple valve body is gathered together.
As preferably, one end of described chamber cover is provided with air input joint, and the other end is provided with plug.
During work, gas enters from air input joint, when the coil electricity of annular, producing electromagnetic force makes iron core overcome the active force of Returnning spring, and now valve port end is opened, and gas enters from valve port end and exports from outlet side, when the coil blackout of annular, dynamic plunger return under the effect of Returnning spring, valve port end is closed, and now outlet side does not have gas to export.
The beneficial effects of the utility model are: recess only includes a bottom surface and a sidewall, and in the cross section of recess, straight line corresponding to bottom surface and the straight line corresponding to sidewall form acute angle, such setting can make the space wastage of static iron core end face less, thus under square one, the electromagnetic attraction of the solenoid valve of this kind of structure can be much larger, and the design of acute angle can effectively prevent buffer gasket in collision process from departing from static iron core.
