Electric butterfly valve is this type of regulating valve. Its stop valve is an annular disc or disc, and its key is composed of an oil circuit board, a valve stem, a disc and a sealing ring. The oil circuit board is cylindrical, radial and short in length, and has an embedded butterfly plate. The butterfly plate of the butterfly valve is fixed on the diameter of the pipe. In the cylindrical safety passage of the butterfly valve oil circuit board, the disc-shaped butterfly plate rotates around the center line with a rotation angle of 0° to 95°. When rotated to 95°, the gate valve will fully rotate. It has been opened.
The electric butterfly valve is simple in structure, light in weight, very light, and consists of several parts. In addition, it is easy to use because it can be opened and closed quickly by just rotating 95°. At the same time, the gate valve has excellent fluid control characteristics. When the butterfly valve is in the fully open position, the frictional resistance when the material flows through the oil circuit plate is only the thickness of the butterfly plate, so the air pressure generated by the gate valve is not large and good. Flow monitoring feature. Butterfly valves have two types of seals: elastic seals and metal seals. For malleable sealed gate valves, the sealing ring can be installed in the oil circuit board or near the butterfly plate.
