The submerged electromagnetic pulse valve seat is embedded in the air bag for installation, with low resistance, good circulation, high injection volume, increased load carrying capacity, and expanded range of gas source pressure. It is suitable for use in situations with a wide range of gas source pressures.

working principle:

The diaphragm divides the submerged electromagnetic pulse valve into two chambers, front and rear. When compressed air is connected, it enters the rear chamber through the throttle hole. At this time, the pressure in the rear chamber presses the diaphragm component tightly against the output port of the valve, and the electromagnetic pulse valve is in the "closed" state.

The electrical signal of the pulse jet control device causes the electromagnetic pulse valve armature to move backwards, the vent hole in the rear chamber of the valve opens, the rear chamber rapidly loses pressure, the diaphragm component moves backwards, compressed air is blown through the valve output port, and the electromagnetic pulse valve is in the "open" state. The electrical signal of the pulse jet controller disappears, the electromagnetic pulse valve armature resets, the rear chamber vent hole closes, and the pressure in the rear chamber increases, causing the diaphragm component to tightly adhere to the output port of the valve. The electromagnetic pulse valve is then in the "closed" state.
