Valve electric actuator, in short, is a device that drives the opening, closing, or regulating of valves through an electric motor. It is widely used in fluid control systems, which can accurately control the on/off state and opening degree of valves, achieving precise control of fluid media.
Electric motor drive: The core component of an electric actuator is the electric motor. After receiving the control signal, the electric motor starts to rotate, and the high-speed rotation is converted into low-speed, high torque motion suitable for valve operation through the deceleration device.
Deceleration device: The output of the electric motor is reduced in speed and increased in torque by the deceleration device, ensuring that the valve can open and close smoothly.
Transmission mechanism: The motion after deceleration is transmitted to the valve stem through the transmission mechanism, driving the opening and closing action of the valve to achieve precise control.
Control system: The electric actuator is equipped with a control system that receives external control signals and controls the start, stop, and reverse of the motor based on the signals. At the same time, the position feedback device monitors the valve position in real-time to ensure it matches the control signal.
Position feedback: High end electric actuators are equipped with position feedback devices such as potentiometers, encoders, etc., to achieve closed-loop control and ensure precise control of valve opening.
Valve electric actuators are widely used in industries such as petroleum, chemical, water treatment, and power. In these fields, it significantly improves production efficiency and system safety by precisely controlling the on/off state and opening degree of valves.
Through the introduction in this article, I believe you have gained a comprehensive understanding of the working principle of valve electric actuators and their applications in multiple industries. As a key equipment in industrial automation control, electric actuators will continue to play an important role and develop with continuous technological innovation.
