DB120 DB120/C Diaphragm For Mecair Pulse Solenoid Valve VNP220 VNP420

Brief introduction of electromagnetic pulse valve diaphragm:

DB120 ( DB120/C ) Diaphragm ( Membrane ) for Mecair pulse valve VNP220, VEM220, VNP420, VEM420, VNP424, VEM424, VNP620, VEM620, VNP720, VEM72; NBR material is standard, working temperature range is -5 to +80 ℃; material is optional, for high temperature, working temperature range is -10 to +120 ℃. On a pulse jet baghouse pulse valves (also called diaphragm valves) control the release of air pulses during the cleaning cycle. When the baghouse control board or timer board initiates a cleaning cycle it sends an electrical signal to the solenoids, when then activate the pulse valve. Inside the pulse valve, a rubber diaphragm opens and closes to release the compressed air stored in the air header tank. The air then passes through the valve into the blow pipes above the filters and then is directed down into the filters to clean them.

Working principle:

The electromagnetic pulse valve diaphragm divides the pulse valve into two air chambers. When the pressure of the rear air chamber makes the diaphragm close to the air outlet of the valve, the pulse valve is in a closed state, the pulse controller outputs a signal to move the armature of the pulse valve, the vent hole of the air chamber behind the valve is opened, and the rear air chamber quickly loses pressure, making the The diaphragm moves backward, the compressed air is blown through the outlet of the valve, the pulse valve is in the open state, the injection starts, the electrical signal output by the pulse controller disappears, the electromagnetic pilot of the pulse valve is reset, the vent hole of the rear air chamber is closed, and the back When the pressure of the air chamber rises, the diaphragm of the pulse valve is close to the air outlet of the valve, the pulse valve is in the closed state, and the injection stops. The length of the injection time is controlled by the controller.

Structural properties:

The operating temperature range and pressure range of the diaphragm itself depends on the type of rubber, fabric and structure. The diaphragm can work under the conditions of -50~100 degrees Celsius and 0.4~0.8MPa; the fluororubber and silicone rubber diaphragms can work under the conditions of -80~232 degrees Celsius. Chlorohydrin rubber diaphragm can work under the pressure of 0.4~0.8MPa, has good air tightness, anti-aging, and its life is equal to that of engine overhaul.
