The butterfly pneumatic valve model establishment method

butterfly pneumatic valve, pneumatic valve, also called frame is a kind of regulating pneumatic valve has simple structure, can be used in low pressure pipeline medium switch control the pneumatic butterfly valve is closed ( Pneumatic disc or disc) For disc, shaft rotation around the pneumatic valve to open and close of a pneumatic valve, pneumatic valve can be used to control air, water, steam, all kinds of corrosive medium, mud, oil, liquid metal and radioactive medium such as various types of fluid flow. Mainly in the line cut off and throttling effect. Butterfly pneumatic valve opening and closing is a disc-shaped butterfly plate, the pneumatic valve body around its own axis of rotation, so as to achieve the aim of opening and closing or adjust.
butterfly pneumatic valve structure is mainly composed of pneumatic valve, pneumatic valve stem, disc and seal ring. Pneumatic valve body is cylindrical, short axial length, built-in butterfly plate.

butterfly pneumatic valve working principle: butterfly plate driven by pneumatic valve stem, if turned °, can complete an opening and closing. Change the butterfly plate deflection Angle, can control the flow of medium.
use condition and medium: butterfly pneumatic valve is suitable for the generator, gas, natural gas, liquefied petroleum gas, city gas, cold hot air smelting, chemical industry and power generation, environmental protection, such as, building water supply and drainage engineering system in conveying all kinds of corrosive fluid pipe, non corrosive, used to adjust and block the flow of the medium.
