Operating principle and function of actuator of electric control valve
For electric control valve You may not be unfamiliar with it. Many people know that it is actually composed of a regulating valve body and an electric actuator. Today we will talk about the working principle and specific functions of the actuator of this electric regulating valve.
In the control of modern production process, the electric actuator plays a very important role. The electric actuator is an indispensable part of the automatic regulation system. It plays an important role in modern production process control.
Electric actuator is a very important equipment component in electric control valve and some control valve systems. This equipment can drive the valve to carry out automatic regulation mechanism. In addition to combined use with regulating valves, electric actuators can also be divided into electric motors and electric manipulators according to different structural principles and application occasions. Of course, electric regulating valves are mostly used at present, which are widely used in the flow control of fluid medium and the regulation of electronic equipment in the production process.
The electric regulating valve is composed of a pushing part (actuator) and a regulating part (valve). Since the valve is directly installed on the process pipeline, the service conditions are generally poor, such as high pressure, high temperature, deep freezing, strong corrosion, easy to use, explosive, easy to leak, easy to crystallize, high batch and even toxic. Therefore, its performance will directly affect the normal working conditions of the regulating system. At the same time, its characteristics (including actuator and valve) It is also closely related to the regulation quality of the regulation system. The characteristics of the actuator are determined by the actuator itself and the combination of the valve positioner and the actuator.
