What electric actuator is used for pneumatic butterfly valve?
It adopts worm gear and worm reduction mechanism and has locking function. The high-strength glass lens sintering process is adopted to make the window opening more beautiful and smooth, and the electrical limit travel position makes the electrical limit adjustment more simple and accurate. It has internal servo operation, position feedback of opening signal, position indication, manual operation and other functions. Powerful function, reliable performance and simple connection. Through the input of current signal or voltage signal, the rotation angle of the ball core can be changed to achieve proportional adjustment. The channel is flat and smooth, and is not easy to deposit media. It can be transported through ball pipes, with simple structure, light weight and good sealing performance. Equipped with motor and handwheel, its working principle can be implemented: a pair of large bevel gears and small bevel gears in the reduction gearbox drive the driving pinion (Z=8), and then drive the counter to work. If the counter is adjusted according to the opening and closing position of the valve, when the counter rotates with the output shaft to the preset position (number of revolutions), the cam will rotate 90 °, forcing the microswitch to act, cutting off the power supply of the motor, and stopping the motor, so as to control the travel (number of revolutions) of the electrical equipment. At present, it has been widely used, mainly for flammable and explosive occasions, with high safety factor, strong operation function and stable performance. Electric actuator is the driving device of the valve, which can realize opening, closing or regulating control. It is suitable for making 90 ° rotary valve for butterfly valve, ball valve, plug valve and damper. Next, let me talk about its components. Electric and manual operation. It is suitable for small and medium-sized butterfly valves, ball valves, plug valves and other 90 degree steering valves and similar equipment. Equipped with travel control and torque limiting mechanism.
