Working principle of vacuum diaphragm valve:
Vacuum diaphragm valve uses the valve stem to directly press the rubber film onto the valve seat, which is used to cut off or connect the vacuum system. The connection forms used include looped flange connection, quick release flange connection, and welded connection. Welding type connection is divided into welding type I connection (i.e. welded at both ends) and welding type II connection (i.e. welded at one end and inserted at the other end). The working medium suitable for valves is air and non corrosive gases.
Characteristics of vacuum diaphragm valve:
Compact, simple, small in size, and aesthetically pleasing in appearance;
The switch is guided and moves smoothly;
Small closing torque, long service life, ≥ 30000 times;
The diaphragm compression can be automatically adjusted, with even compression and reliable sealing;
The diaphragm is inserted into the valve core using a push type, making it easy to replace;
Application of vacuum diaphragm valve: Used in vacuum, dairy products, wine industry, biotechnology, food, pharmaceuticals, beverages, cosmetics, and chemical industries.
