Long Working Cycles Life NBR Solenoid Valve Diaphragm With 8 Mounting Hole Number

Over 1 Million Working Cycles Life NBR Solenoid Valve Diaphragm with 8 Mounting Hole Number

Electromagnetic pulse valve diaphragm is the main component of bag-type filter ash removal system, which is mainly used in pump valve, automobile industry, pneumatic components, gas equipment, electronic industry, electrical equipment, pneumatic and hydraulic industry and other industries. 

The common material of pulse valve diaphragm is rubber. Rubber diaphragm is mainly used in flow, pressure, differential, liquid level, constant temperature volume thermal compensation valves, regulating valves, automatic mechanical follow-up devices, switches and counters. Its advantages are high reliability, good complexity, long working life and low cost. Uniform elastic structure can be used in all kinds of rubber. The rubber diaphragm has a long service life and can be operated synchronously with other control components to ensure the injection of pulse compressed air. Even under extremely harsh working conditions, it can guarantee its normal work and long service life.

Operation of electromagnetic pulse valve diaphragm

The pulse valve diaphragm is the air switch of the electromagnetic pulse valve. The pressure gas controlled in front of the diaphragm lifts the diaphragm, opens the electromagnetic pulse valve channel and sprays on it, the electrical signal disappears, and the spring of the electromagnetic leader immediately resets the moving column and closes the unloading hole. Electromagnetic pulse valve diaphragm control gas pressure and diaphragm spring force after close the channel, the electromagnetic pulse valve to stop the resistance of injection on the diaphragm hole, when the guide head moving column is raised, when gas pressure unloading, electromagnetic pulse valve diaphragm have the effect of air resistance, when unloading closed cavity, after pressure gas is quickly to make the electromagnetic pulse valve diaphragm close the channel, stop blowing.

Structure performance

It is composed of single or multiple layers coated on both sides, and it is also made of rubber without fabric. Membrane pressure method according to its shape. According to the requirements of the use of different materials can be manufactured, different fabric diaphragm. The properties of the butyronitrile rubber and polysulfide rubber used for the film, the properties of the rubber used for the canvas disc film (often called diaphragm) and the properties of some silicone rubber, fluorine rubber and chlorohydrin rubber film developed in recent years are described as follows.

The operating temperature and pressure range of the diaphragm itself depends on the rubber, fabric and structure. The diaphragm can work at -50~100 c and 0.4~ 0.8mpa. Fluorine rubber and silicone rubber diaphragm can work at -80~232 c. Chlorohydrin rubber diaphragm can work under pressure of 0.4~ 0.8mpa, good air tightness, aging resistance, life and engine overhaul life is equal.
