Adjustment of the pneumatic valve working performance

butterfly butterfly plate installed on the diameter of the pipe of pneumatic valve. In cylindrical channels of pneumatic valve pneumatic butterfly valve body and disc disc around the axis of rotation, rotation Angle for ° ~ °, rotate to °, the pneumatic valve is fully open.
butterfly pneumatic valve has simple structure, small volume, light weight, material consumption province, small installation size, small quick, ° reciprocating rotary switch, low driving torque, etc, used for truncation, connected, regulate medium in pipe has good flow control characteristics and close the sealing performance.
butterfly pneumatic valve in the fully open position, the butterfly plate thickness is medium flows through the pneumatic valve when the only resistance, so by the pneumatic valve pressure drop is small, so it has good flow control characteristics. Butterfly pneumatic valve seal and metal sealing machine has two sealing type. Elastic sealing pneumatic valve, sealing ring to be set on the pneumatic valve body or attached to the butterfly plate peripheral.
if required control pneumatic valve used as flow control, mainly is the right choice of size and type of pneumatic valve. Adjusting the structure principle of pneumatic valve is especially suitable for production of large diameter pneumatic valves. Butterfly pneumatic valve not only in the oil, gas, chemical industry, water treatment and other general industrial used widely, but also applied to the cooling water system of thermal power plants.
butterfly plate streamline design, make the loss of the fluid resistance is small, is a kind of energy-saving products.
pneumatic valve stem for stem structure, through conditioning processing, has the good comprehensive mechanical properties and corrosion resistance, abrasion resistance. Butterfly pneumatic valve open/close the pneumatic valve stem make rotation movement up and down and run, not only of pneumatic valve stem packing is not easy to damage, reliable sealing. With the butterfly plate fixed cone pin, overhanging end to prevent rushed out of the design, so as to avoid the pneumatic valve stem and disc joint pneumatic valve stem collapse accident broke out.
