Pneumatic valve diaphragm structure performance
Pneumatic valve diaphragm structure performance
It consists of a single layer or multiple layers of rubber on both sides, but there are also rubber-free fabrics. According to the shape of the membrane pressure method. According to the requirements of use can be made of different rubber, different fabric membrane. The properties of the blends of nitrile rubber and polysulfide rubber used for diaphragms, the properties of rubber compounds used to clamp canvas diaphragms (often referred to as diaphragms), and some silicone rubber, fluoroelastomers, and chlorohydrin rubbers developed in recent years. The diaphragm performance is as follows.
The operating temperature range and pressure range of the laminated film itself depend on the type of glue, fabric and structure. The diaphragm can work under -50~100 degrees Celsius and 0.4~0.8MPa. Fluoroelastomer and silicon rubber diaphragm can work at -80~232 degrees Celsius. Chlorohydrin rubber diaphragm can work under pressure of 0.4~0.8MPa, good airtightness, anti-aging, lifespan equal to engine overhaul life.
