Tips: Pneumatic butterfly valve working principle
The pneumatic butterfly valve uses a circular butterfly plate that rotates with the valve stem to open and close, and the pneumatic valve that realizes the activation action is mainly used as a cut-off valve, and can also be designed to have the function of adjustment or segment valve and adjustment. Increasing use of medium diameter pipes.
The pneumatic butterfly valve is simple in structure, small in size and light in weight. And it only needs to rotate 90° to open and close quickly, the operation is simple, and the electric valve has good fluid control characteristics. When the butterfly valve is in the fully open position, the thickness of the butterfly plate is the single resistance when the medium flows through the valve body, so the pressure drop generated by the valve is very small, so it has better flow control characteristics. Butterfly valves have two types of seals, including elastic seal and metal seal. The sealing ring can be inlaid on the valve body or attached to the periphery of the disc.
If the butterfly valve is required to be used for flow control, it is necessary to select the correct size and type of the valve. The structural principle of the butterfly valve is especially suitable for making large-diameter valves. Butterfly valves are not only widely used in general industries such as petroleum, gas, chemical, water treatment, etc., but also in the cooling water system of thermal power plants.
