Worm gear of the pneumatic valve plate installed in pipeline diameter direction.
In pneumatic valve pneumatic valve cylindrical passage, disc plate around the axis of rotation, rotation Angle for 0 ° ~ 90 °, when plate rotation to 90 °, pneumatic valve is fully open.
worm gear pneumatic valve has simple structure, small volume, light weight, only by a few parts. And only need to rotate 90 ° can rapid opening and closing, simple operation, at the same time, the pneumatic valve has good flow control characteristics. Flange pneumatic valve in the fully open position, the pneumatic valve elastic seal and metal seal two kinds of seal type. Elastic sealing pneumatic valve, sealing ring to be set on the pneumatic valve body or attached to the 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 valve used as flow control, mainly is the right choice of size and type of pneumatic valve. The structure principle of pneumatic valve is especially suitable for production of large diameter pneumatic valves. 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.
commonly used pneumatic valve has the wafer pneumatic valve and flange type pneumatic valve two kinds. The wafer pneumatic valve pneumatic valve is in the stud connection in place between two pipe flanges, the flange type pneumatic valve is pneumatic valves with flange, bolts on the pneumatic valve flange connection on the pipe flange on both ends.
in the fully open position, the 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. 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 plate peripheral.
