Old Version DMF-Z-20 DMF-ZM-20 Pneumatic Valve Diaphragm For Dust Collector Air Valve Pneumatic Actuator 3/4 Inch FKM
The electromagnetic pulse valve (also called diaphragm valve) is the compressed air "switch" of the dust cleaning and blowing system of the pulse bag filter. Under the control of the output signal of the pulse controller, the filter bags are injected and cleaned one by one to keep the resistance of the precipitator within the set range, so as to ensure the processing capacity and dust collection efficiency of the precipitator.
The diaphragm divides the electromagnetic pulse valve into two chambers, the front chamber and the back chamber. When the compressed air is connected, the compressed air enters the back chamber through the throttle hole. At this time, the pressure of the back chamber presses the diaphragm against the output port of the valve, and the electromagnetic pulse valve is in the "closed" state.
The electric signal of the pulse controller makes the armature of the pulse valve move, the vent hole of the air chamber behind the valve opens, and the pressure of the air chamber behind the valve loses rapidly. The diaphragm moves backward and compressed air is injected through the valve output port. The pulse is on.
The electric signal of the pulse injection controller disappears, the armature of the electromagnetic pulse valve is reset, the vent hole of the rear air chamber is closed, the pressure of the rear air chamber is increased to make the diaphragm close to the valve outlet, and the electromagnetic pulse valve is in the "closed" state.
