Opening indicating mechanism
Input gear Driven by the counter's gear, after deceleration, the indicator plate rotates simultaneously with the switching process of the valve to indicate the switching amount of the valve. The potentiometer shaft and the indicator plate rotate synchronously for remote transmission opening indication. The number of turns can be changed by moving the turns adjustment gear. The opening indicating mechanism is equipped with a micro switch and a cam. When the electric device is running, the rotating cam periodically causes the micro switch to operate. The frequency is that the output shaft rotates once and operates once or twice, which can be used for flash signals. .
Stroke control mechanism
Yangzhou Zhongnan brand valve actuator, valve electric device stroke counter, stroke switch, limit switch.
The stroke control mechanism adopts the principle of decimal counter, also known as counter, with high control accuracy. The working principle is that a pair of large and small bevel gears in the reduction box drive the intermediate pinion, and then drive the stroke control mechanism to work. If the stroke controller has been adjusted according to the valve switch position, when the controller rotates with the output shaft to the pre-adjusted position or number of turns, the cam will rotate, forcing the micro switch to act, cutting off the power to the motor, and the motor stops, thus Realize the control of the stroke or number of turns of the electric device.
Torque control mechanism
Yangzhou Zhongnan brand valve actuator, valve electric device torque controller, torque limit switch, torque switch, overload switch, torque control mechanism.
When the output shaft receives a certain torque, the worm not only rotates but also produces axial displacement, driving the crankshaft, which drives the bracket directly (or through a bumper) to produce angular displacement. When the torque on the output shaft increases to the set torque, the displacement generated by the bracket causes the micro switch to operate, thus cutting off the power supply and the motor stops. In this way, the output torque of the electric device is controlled, thereby achieving the purpose of protecting the electric valve.
