The structure characteristics of electric control shutter pneumatic valve

electric adjustment is automatically adjust the characteristics of pneumatic valves, by the pneumatic valve body, shutter panels, pneumatic valve shaft, connecting rod mechanism, drive the main parts, such as pneumatic valve body for welding structure, door plank is composed of several around the shutter panels of axis of rotation movement of shaft end using the flexible graphite braided packing seal, has the characteristics of high temperature resistance, self-lubrication. Working principle of the pneumatic valve is a device driver output torque through the linkage to the pneumatic valve shaft, by the pneumatic valve shaft rotation drive the respective shutter panels, to change the pipe sectional area, in order to achieve large area of cutting medium, to reduce the medium pressure or adjust the action of medium flow rate, adjust the Angle for - °. It has simple structure, small flow resistance, light weight, flexible rotation, long service life, convenient operation and maintenance.
