Electric ball valve of valve is also called electric ball valve of valve pipe, flexible electric ball valve, electric ball valve, flexible electric ball valve, high pressure electric ball valve, valve shock absorber, pneumatic valve, etc. According to the connection mode, it can be divided into loose flange type, fixed flange type and threaded type; According to the structure, it can be divided into five types: single sphere, double sphere, reducer, curved sphere and wind pressure coil. The tubular valve part is composed of inner and outer rubber, cord fabric and steel ring, which is formed by vulcanization and then loosely combined with metal flange or parallel joint. This product can reduce vibration and noise, and can compensate for thermal expansion and cold contraction caused by temperature change. It is widely used in various pipeline systems.
The electric ball valve is widely used in the process of pipe connection, and has strong adaptability to various media. Most of the electric ball valves in use now are flange plates at both ends, which are used to connect with the pipeline. All the raw materials in the middle are valve raw materials. Once the pipeline has a large displacement or change, the electric ball valve is likely to be pulled, which may damage the electric ball valve directly.
