submerged pulse valve

Submerged pulse valve, with the valve seat embedded in the air bag, has low resistance, good circulation, high injection volume, improves load carrying capacity, expands the range of gas source pressure, and is more suitable for use in situations with wide gas source pressure.

working principle

The diaphragm divides the 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.
