The function of the butterfly valve of the compressed air pipe handle

The functions of the handle butterfly valve in the compressed air pipeline mainly include the following aspects:

1. Cut-off and throttling: Butterfly valves can be used to control the flow of various types of fluids such as air, water, steam, various corrosive media, slurry, oil, liquid metal and radioactive media. On the compressed air pipeline, it mainly plays the role of cutting and throttling.

2. Quick opening and closing: The handle butterfly valve has the characteristics of compact structure, small size and light weight, and its disc-shaped butterfly plate rotates around the axis, and only needs to rotate 90° to quickly open and close, and the operation is simple.

3. Flow control: The butterfly valve has a large opening angle, usually 90 degrees, which makes the gas flow control more accurate. In the fully open position, the thickness of the butterfly plate is the only resistance when the medium flows through the valve body, so the pressure drop generated through the valve is very small, so it has good flow control characteristics.

4. Space advantage: Due to the small size and small space occupation of the butterfly valve, it is especially suitable for use in occasions with limited space.

5. Sealing performance: Although the sealing performance of butterfly valves is slightly worse than that of ball valves and gate valves, it can still achieve better sealing effects in some occasions where the sealing requirements are not very high, or through specific designs (such as double eccentricity and a special oblique cone oval sealing structure used in high-performance manual butterfly valves).

In summary, the handle butterfly valve in the compressed air pipeline is mainly used to control the flow of gas, which has the advantages of fast opening and closing, accurate flow control, and small space occupation, but it needs to be considered according to the specific application scenarios and requirements when choosing to use.
