A butterfly valve, also known as a flap valve, is a simple structure regulating valve that can be used for the switch control of low-pressure pipeline media. A butterfly valve refers to a valve with a disc as the closing element (valve disc or butterfly plate) that rotates around the valve axis to achieve opening and closing. The valve 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. Mainly used for cutting and throttling on pipelines. The butterfly valve opening and closing part is a disc shaped butterfly plate that rotates around its own axis within the valve body to achieve the purpose of opening, closing or adjusting.
Ultra low temperature butterfly valve structure:
Mainly composed of valve body, valve stem, butterfly plate, and sealing ring. The valve body is cylindrical in shape, with a short axial length and a built-in butterfly plate.
Working principle of ultra-low temperature butterfly valve:
The butterfly plate is driven by the valve stem, and if it is turned over 90 °, it can complete one opening and closing. By changing the deflection angle of the butterfly plate, the flow rate of the medium can be controlled.
Operating conditions and media:
Butterfly valves are suitable for pipelines conveying various corrosive and non corrosive fluid media in engineering systems such as furnaces, gas, natural gas, liquefied petroleum gas, urban gas, cold and hot air, chemical smelting, power generation, environmental protection, building water supply and drainage, etc. They are used to regulate and cut off the flow of media.
