How many lines control the commissioning method of pneumatic high-temperature lining butterfly valve? Action principle of pneumatic butterfly valve Action principle:
a. When the electric piston actuator is double acting: the air source signal pressure of the pneumatic butterfly valve output by the double acting positioner is respectively input into the left and right two air chambers of the actuator piston. Because the air source pressures of the left and right two air chambers of the input piston are different, a pressure difference is formed, which drives the piston to make a linear motion. Through gear and rack transmission, the linear movement of the piston is converted into the rotary movement of the main shaft of the actuator until the pressure of the left and right air chambers is balanced and the movement stops. While the actuator rotates, it drives the valve rod and valve core to rotate, changing the flow area between the valve core and valve seat to achieve the purpose of adjustment.
、 Sixth, it has automatic cleaning function. What should we do if there are various irrelevant impurities in the pipeline that need to be cleaned? Please rest assured that if you buy an electric switch butterfly valve, it can easily cut off all kinds of impurities and ensure the smoothness of the pipeline.
