Type of pneumatic butterfly valve
Pneumatic butterfly valves belong to the category of automatic valves, which are mainly used in boilers, pressure vessels, air conditioners and solar energy pipelines. The control pressure does not exceed the specified value, which plays an important role in protecting the operation of mechanical equipment. Refining pneumatic butterfly valve is one of the important accessories of pressure vessels in petrochemical industry. It is used to control the pressure of empty containers and ensure the safety of containers. This series of pneumatic butterfly valves are closed and fully open spring pneumatic butterfly valves, that is, when the pressure of the gas medium is 3% higher than the set pressure, the opening height of the valve disc exceeds one fourth of the diameter of the valve core. Flow channel.
Structure and function of pneumatic butterfly valve The function of pneumatic butterfly valve is to protect the safe operation of pressure pipeline, pressure vessel or equipment. When the pressure rises to a certain safety pressure, it will take off automatically. Pneumatic butterfly valves are widely used in boilers, pressure pipes and containers in chemical, electric, petroleum, construction, metallurgy and other industries.
