The electric ball valve is composed of two flanges and a sphere. Generally, there are two processing technologies for valve ball: hard mold and gas mold. The pneumatic model is better. Carbon steel flanges are divided into forged flanges and cast steel flanges. Forged flanges are better than cast steel flanges. The electric ball valve can be divided into loose flange type, fixed flange type and threaded type according to the connection method; According to the structure, it can be divided into five types: single sphere, double sphere, reducer, curved sphere and wind pressure coil.
The electric ball valve is a very practical pipe fitting. The electric ball valve is composed of a tubular valve part composed of inner and outer rubber, cord layer and steel wire ring, which is formed by vulcanization and then loosely combined with a metal flange or parallel joint. It has the characteristics of high pressure resistance, good elasticity, large displacement, balancing pipeline deviation, absorbing vibration, good noise reduction effect, convenient installation, etc.
The electric ball valve can reduce the vibration and noise of the pipeline, and can compensate for the thermal expansion and cold contraction caused by temperature changes. It is widely used in various pipeline systems. The time of selection depends on your own actual situation. If it is used in projects with low requirements and reasonable price, it is suggested to use the electric ball valve of cast steel air mold process. If it is a large project with high requirements for equipment conditions, forging air die is recommended. A few years ago, it was made of cast steel. When the requirements are not high, it can also be used. Yuanda advocates that customers choose different electric ball valves according to the actual situation.
