Description of Butterfly valve
Butterfly valve is a common valve type with new and reasonable design, unique structure, light weight and rapid opening and closing. This kind of valve is mainly composed of main components such as valve body, butterfly plate, multi-layer valve seat, valve stem, and transmission mechanism. The butterfly plate of the clamp handle butterfly valve is installed in the diameter direction of the pipe. In the cylindrical channel of the valve body, the disc-shaped butterfly plate rotates around the axis with a rotation angle of 0°-90°. When rotated to 90°, the valve is fully open. This kind of valve is generally installed horizontally. It has the advantages of simple structure, small size and light weight. It can be opened and closed quickly by rotating 90° and is easy to operate. At the same time, the wafer handle butterfly valve has good fluid control characteristics. When it is in the fully open position, the thickness of the butterfly plate is the only resistance when the medium flows through the valve body. Therefore, the pressure drop generated by the valve is very small and has a good flow rate.
Advantages of Butterfly valve
1. Simple structure and reliable sealing;
2. Wide application range, high strength and good corrosion resistance.
3. Heavy-duty valve body, durable, the valve body is a solid body, and in terms of weight, it is a heavy-duty product;
4. Handle control, simple and convenient;
5. Complete models, multiple materials available.
