DMF-Z-25 1'' Inch Diaphragm Bag Filter Dust Collector Pulse Valve
DMF-Z-25 1'' Inch Diaphragm Bag Filter Dust Collector Pulse Valve
Working Principles:
The electromagnetic pulse valve is composed of electromagnetic pilot operator, diaphragm and valve body. Due to difference of pressure acting on two sides of the diaphragm, the diaphragm is pressed closely against the outlet of valve to keep the valve stays in “closed” position.
When energized by an electric signal from the controller, the electromagnetic armature will move to open the discharge opening of back cavity. The compressed air in back cavity bursts out to relief pressure and pressurized air in front cavity pushes up the diaphragm to open the main outlet of valve, then the electromagnetic pulse valve opens and starts to blow.
When the signal disappears and the spring works immediately to send the pilot operator back to its original position and close the discharging opening. The diaphragm will close the passage by the effect of the pressure in the front cavity and the spring. The pulse valve stops blowing.
The orifice in the diaphragm damps the airflow when the armature is lifting up for releasing the pressure. When the discharge hole closed, the pressure gas will fill into the front cavity to close the passage by the diaphragm. The pulse valve stops blowing.
