Electromagnetism high vacuum inflation valve

The utility model relates to an electromagnetism high vacuum inflation valve, it includes electric magnetic component, armature, case, upper cover, presss from both sides cloth diaphragm, diaphragm pressure disk, diaphragm seat, filter and main part etc.. Need the breaking vacuum state as vacuum system, when filling into the air, the circular telegram of electric magnetic component, armature is inhaled upwards to the case, arouses that back pressure chamber room and working gas cavity atmospheric pressure change, makes the diaphragm seat and presss from both sides the cloth diaphragm and throw off the pipeline mouth in the main part, fills into vacuum system from filter or air cleaner incoming air. When vacuum system's vacuum drops to the predetermined value, the outage of electric magnetic component, it is downward to go up the spring force, makes clamp cloth diaphragm compress tightly the pipeline mouth in the main part, seals vacuum system. The utility model discloses an electromagnetism high vacuum inflation valve can be based on setting in advance in connecting the vacuum pipe, in time destroys or control vacuum system's vacuum.
