Stainless steel working principle of the pneumatic flange butterfly valve

pneumatic flange butterfly valve, butterfly pneumatic valve with pneumatic actuator. Pneumatic actuators to perform relatively fast speed, and does not require hands-on workers, to a great extent, save the human resources and time. The main advantage of the pneumatic flange butterfly valve, simple structure, small volume light weight, low cost, the pneumatic disc characteristics of pneumatic valve which is particularly significant, installed in the upper air tunnel, through two five-way solenoid pneumatic valve control is easy to operate, also can adjust the flow medium. Fluid resistance is small, large diameter pneumatic drive pneumatic valve fully open effective circulation area is larger, easy opening and closing fast, disc pull rotation Angle can complete opening and closing, due to the rotation axis disc plate hand medium force nearly equal, and the torque in the opposite direction, thus opening and closing torque is small, low pressure can achieve good sealing, pneumatic valve disc sealing material with nitrile butadiene rubber, fluorine rubber, rubber, four fluorine lining so sealed performance is good, the pneumatic valve as soft hard cascading metal hard seal plate with metal hard seal and elastic sealing advantages, under low temperature circumstances has excellent sealing performance.
working principle of the pneumatic flange butterfly valve structure applicable environmental analysis
butterfly butterfly plate of pneumatic valve installed on the diameter of the pipe direction. In pneumatic flange butterfly valve pneumatic valve, cylindrical channels in the disc disc around the axis of rotation, rotation Angle for ° ~ °, rotate to °, the pneumatic valve is fully open.
control pneumatic valve has simple structure, small volume, light weight, only by a few parts. And simply rotate ° rapid opening and closing, simple operation, at the same time the electric pneumatic valve has good flow control characteristics. Pneumatic flange butterfly 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, it has good flow control characteristics. Pneumatic flange butterfly 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.
use metal sealing pneumatic valve generally live longer than elastic sealing pneumatic valve, but it is hard to be completely sealed. Metal sealing can adapt high working temperature, elastic seal has the defect of being limited by the temperature.
if required pneumatic flange butterfly valve is 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.
stainless steel flange butterfly working principle of the pneumatic valve pneumatic
stainless steel pneumatic butterfly valve is used with the rotation of the pneumatic valve orange circular disc to do, to be opened in order to realize the opening action of pneumatic pneumatic valves are used mainly for truncation of pneumatic valve, can be designed to have a adjustment or period of pneumatic valve and adjustment function, the current disc pneumatic valve on the low voltage and medium caliber pipe used more and more.
disc of the major advantages of the pneumatic valve, simple structure, small volume light weight, low cost, the pneumatic drive characteristics of the pneumatic valve is particularly significant, installed in the upper air tunnel, through two five-way solenoid pneumatic valve control is easy to operate, also can adjust flow medium. Fluid resistance is small, large diameter pneumatic drive pneumatic valve fully open effective circulation area is larger, easy opening and closing fast, disc pull rotation Angle can complete opening and closing, due to the rotation axis disc plate hand medium force nearly equal, and the torque in the opposite direction, thus opening and closing torque is small, low pressure can achieve good sealing, pneumatic valve disc sealing material with nitrile butadiene rubber, fluorine rubber, rubber, four fluorine lining so sealed performance is good, the pneumatic valve as soft hard cascading metal hard seal plate with metal hard seal and elastic sealing advantages, under low temperature circumstances has excellent sealing performance.
