Clean Air Working Medium NBR Pulse Valve D20 Diaphragm for Dust System
Electromagnetic valve diaphragm also known as pulse valve diaphragm is pulse bag filter ash removal system of blowing gas path "switch" and one of the components of the normal operation of the valve body. The electromagnetic pulse valve diaphragm to choose the most suitable for high quality rubber for the production of electromagnetic pulse valve diaphragm plate production, with a strong oil resistance high temperature resistant, alkali resistant features, can easily guarantee and other control components, fully synchronous operations carried out control pulse compressed air blowing. Even in extremely harsh working conditions, it can ensure its normal work and long service life. Diaphragm under the environment temperature is 20-80 ℃, under working pressure difference of 0.8 MPa, the working life is not low and 1 million times.

Diaphragm working instruction
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.
Working principles of SBFEC type Pulse Valve
Pulse valve diaphragm before and after the pulse valve is divided into two air chamber, when electromagnetic pulse valve in the pulse bag filter dust on the clean compressed air system, the compressed air through the orifice, after entering air chamber, the gas chamber pressure after the air outlet of the valve on the diaphragm is clingy, pulse valve closed, the pulse controller output signal, the pulse valve moving armature, stomatal opening after the valve chamber, rapid loss of pressure chamber, make diaphragm backward-shift, compressed air through the outlet valve injection, injection, pulse valve is fully open pulse controller output signal disappears, the electromagnetic pulse valve pilot title iron reduction, air chamber after put the stomatal closure, After the air chamber pressure increases, the pulse valve diaphragm 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.
Technical requirement of Pulse Valve Diaphram
Due to pulse valve diaphragm needs from time to time opening and closing action is a flexible mechanism to control the air circulation, has good flexibility and requirements, also demanded the sealing as high as possible, so the pulse valve diaphragm material is directly related to the service life of pulse valve diaphragm and using effect, in other words, the pulse valve diaphragm is good or bad will directly affect the working stability of pulse bag filter soot cleaning system, is directly related to the use of dust removal equipment cost, general pulse valve diaphragm has the commitment, the number of service life or actions using high-quality pulse valve diaphragm can directly reduce the cost of the use of dust removal equipment.
