The structure of the butterfly valve is very simple. Compared with other types of valves, the butterfly valve has the advantages of small size, light weight, small operating torque, effortless and rapid switching, etc. In addition, the butterfly valve has good sealing performance, and can also be used for flow regulation, which is currently the most developed.
1. The butterfly valve has a simple structure, small size, light weight, and has a small installation space for occupying pipes. The switch operation is labor-saving and the disc only needs to rotate by 90°.
To achieve the opening and closing of the butterfly valve. The structural characteristics of the butterfly valve make the butterfly valve not only cut off or connected to the medium in the pipeline, but also can be used as a tune.
The throttle valve regulates the medium in the pipeline and has better flow control characteristics.
2. The butterfly valve is generally used in low-pressure pipelines. It can be used in pipes containing impurities such as mud, and there are few impurities accumulated in the pipeline mouth.
3, butterfly valve is energy-saving products. The streamlined butterfly plate minimizes the fluid resistance in the pipe.
4. The stem has a through-shaft structure, high strength, and good corrosion resistance and scratch resistance. When the butterfly valve is on and off, the valve stem only rotates in place horizontally
The movement of the stem at the valve stem is not easily broken and ensures the sealing performance at the filling. In addition, the valve stem is fixed with the disc plate, and the protruding part is prevented
The punch-out design prevents the valve stem from collapsing when the joint between the valve stem and the butterfly plate accidentally breaks.
5, Butterfly valve connection is diversified, there are clips, flanges, butt welds, screw connection and lug to clip connection.
