With the development of automobile industry and industrial technology, valve technology has been widely used in luxury cars, buses, trucks, commercial vehicles, rail vehicles, industrial machinery, industrial equipment and other industries in recent years. What is the point of industrial pneumatic butterfly valves?
1. Diaphragm pneumatic butterfly valve is used for sealing, and self sealing pressure is generally used, while capsule pneumatic butterfly valve is usually connected by thread, so diaphragm pneumatic butterfly valve is simple for sealing and easy for disassembly and installation. Diaphragm pneumatic butterfly valve is simple and easy to mass produce.
2. The pneumatic butterfly valve is covered by a piston, which greatly improves the elasticity of the pneumatic butterfly valve, and obtains the "S" ball valve performance curve which is reverse to the pneumatic butterfly valve.
3. The change rate of effective area of automotive pneumatic butterfly valve is smaller than that of bag type pneumatic butterfly valve. Therefore, when the auxiliary air chamber is small, the diaphragm pneumatic butterfly valve can obtain a lower natural vibration frequency. It is not easy to design a very low frequency ball valve.
