What are the salient features of the membrane electric butterfly 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 electric butterfly valve suspension of passenger cars at home and abroad in recent years. Its characteristics are:
1. At present, membrane electric butterfly valves are used for sealing, which generally use self sealing pressure, while capsule electric butterfly valves are generally threaded, so membrane electric butterfly valves are simple to seal and easy to disassemble. The membrane electric butterfly valve is simple to manufacture and easy to mass produce.
2. It can be seen that the lower cover of the capsule electric butterfly valve forms a piston, and the formation of this change greatly improves the elasticity of the electric butterfly valve, and the inverted "S" shaped butterfly valve characteristic curve is obtained compared with the capsule electric butterfly valve.
3. The change rate of the effective area of the membrane electric butterfly valve is smaller than that of the bag electric butterfly valve. Therefore, when the auxiliary air chamber is small, the membrane electric butterfly valve can obtain a lower natural vibration frequency. It is not easy to design butterfly valve with very low frequency.
