Information
Butterfly valve, also called flap valve, is a kind of regulating valve with simple structure. The butterfly valve that can be used for switching control of low-pressure pipeline medium means that the closing part (disc or butterfly plate) is a disc, which rotates around the valve shaft to achieve opening and closing. A kind of valve that can be used to control the flow of various types of fluids such as air, water, steam, various corrosive media, mud, oil, liquid metal, and radioactive media. It mainly plays the role of cutting off and throttling on the pipeline. The butterfly valve opening and closing part is a disc-shaped butterfly plate, which rotates around its own axis in the valve body to achieve the purpose of opening and closing or adjustment.
The structure of the butterfly valve
It is mainly composed of valve body, valve stem, butterfly plate and sealing ring. The valve body is cylindrical with short axial length and built-in butterfly plate.
The working principle of butterfly valve
The butterfly plate is driven by the valve stem. If it is turned 90°, it can open and close once. Changing the deflection angle of the butterfly plate can control the flow of the medium.
Operating conditions and media: butterfly valves are suitable for conveying various corrosive and non-corrosive fluids in engineering systems such as generators, coal gas, natural gas, liquefied petroleum gas, city gas, hot and cold air, chemical smelting, power generation and environmental protection, building water supply and drainage, etc. On the pipeline of the medium, it is used to adjust and cut off the flow of the medium.
