Working principle
1.Electromagnetic pulse valve consists of an electromagnetic pilot head,diaphragm and a valve body, a diaphragm cavity after an area larger than the front cavity area, pressure force, so that the film is in the closed position.
2.Electronic instrument input signals, so that the electromagnetic pilot head is movable column, opens the discharge hole, after the diaphragm cavity pressure gas discharge quickly, before the diaphragm cavity pressure gas lift the diaphragm, open channel, pulse valve for injection.
3.Electric pulse signal disappears, electromagnetic pilot head spring to move the column reset immediately closed unloading hole, after the diaphragm cavity gas pressure and spring force so that the diaphragm closes the passageway, valve stop blowing.
4.Diaphragm damping hole on the movable column, when the pilot head lift gas pressure unloading, the damping the effects of airflow, when unloading hole closed, so that the pressure of the gas to rapidly filled with rear cavity, the diaphragm closes the passageway, stop blowing.
