What are the significant features of membrane pneumatic ball valve
With the development of automobile industry and industrial technology, the use of high-strength nylon and kapron curtains has been widely used in the membrane pneumatic ball valve suspension of passenger cars at home and abroad in recent years. Its characteristics are:
1. At present, membrane pneumatic ball valve is used for sealing, which generally uses self sealing pressure, while capsule pneumatic ball valve is generally threaded, so membrane pneumatic ball valve is simple to seal and easy to disassemble. The membrane pneumatic ball valve is simple to manufacture and easy to mass produce.
2. It can be seen that the lower cover of the capsule pneumatic ball valve forms a piston. This change greatly improves the elasticity of the pneumatic ball valve, and the anti "S" shaped ball valve characteristic curve of the capsule pneumatic ball valve is obtained.
3. The change rate of effective area of membrane pneumatic ball valve is smaller than that of bag type pneumatic ball valve. Therefore, when the auxiliary air chamber is small, the membrane pneumatic ball valve can obtain a lower natural vibration frequency. It is not easy to design a very low frequency ball valve.
