In industrial dust removal systems, the DMF – ZM – 40 pulse valve plays a crucial role, and its efficient and stable operation relies on a unique and ingenious working principle.
From a structural perspective, the DMF – ZM – 40 pulse valve is mainly divided into two gas chambers by a diaphragm. When the entire system is connected to compressed air, the compressed air will slowly enter the rear gas chamber through the throttle hole. At this time, the pressure in the rear gas chamber gradually increases until it tightly presses the diaphragm assembly against the output port of the valve, thus putting the electromagnetic pulse valve in the initial “closed” state, like a meticulous guard, firmly controlling the flow of compressed air.
When the pulse blowing control instrument sends an electrical signal, this signal is like giving the pulse valve an “open” instruction. The electrical signal causes the armature of the electromagnetic pulse valve to move rapidly backward, thereby opening the exhaust hole of the rear gas chamber. The air in the rear gas chamber is rapidly expelled in a short period of time, and the pressure instantly drops. Under the action of the pressure difference, the diaphragm assembly moves backward, and the compressed air that was previously blocked rushes out through the valve output port at high speed. At this time, the electromagnetic pulse valve enters the “open” state, and the powerful blowing airflow cleanses the filter bag, blowing off the dust adhering to the surface of the filter bag, ensuring the efficient operation of the dust removal system.
When the electrical signal from the pulse blowing control instrument disappears, the armature of the electromagnetic pulse valve returns to its initial position under the action of the reset device, and the exhaust hole of the rear gas chamber closes. The rear gas chamber then begins to intake air through the throttle hole, and the pressure gradually rises. The diaphragm assembly re-contacts the output port of the valve again, and the electromagnetic pulse valve returns to the “closed” state, waiting for the next blowing command to arrive. This precise and efficient working mode enables the DMF – ZM – 40 pulse valve to operate stably in the dust removal and blowing system of the pulse bag dust collector, continuously contributing to the purification of industrial production environments.
