The electromagnetic pulse valve is the "switch" of the spray air path of the pulse bag filter dust cleaning system, and the key to the normal operation of the valve body inner membrane sheet. The electromagnetic pulse valve diaphragm includes a rivet head for sealing the compressed air pipeline or the outlet of the sealing valve, a venting and unloading hole, and bolt holes for fixed support around it. The electromagnetic pulse valve diaphragm divides the valve body into two chambers, front and rear. The area of the rear control is larger than that of the front control, and the air pressure force is greater.

Electromagnetic pulse valve diaphragm; Divide the pulse valve into two chambers, front and rear. When the electromagnetic pulse valve is connected to clean compressed air in the pulse bag filter cleaning system, the compressed air enters the rear chamber through the throttle hole. At this time, the pressure in the rear chamber presses the diaphragm tightly against the valve outlet, and the pulse valve is in a closed state. The pulse controller outputs a signal to move the pulse valve armature, open the valve rear chamber vent, and cause the rear chamber to lose pressure, causing the diaphragm to move backward. Compressed air is sprayed through the valve outlet, and the pulse valve is in an open state to start spraying. The electrical signal output by the pulse controller disappears, and the electromagnetic pilot head armature of the pulse valve is reset. The rear chamber vent is closed, and the pressure in the rear chamber increases, causing the pulse valve diaphragm to tightly adhere to the valve. The air outlet of the pulse valve is in the closed state, and the spraying stops, The length of the blowing time and the size of the air volume are controlled by the controller.
