The actuator consists of two parts: the actuator and the adjustment mechanism (also known as the control valve). The types and configurations of the adjustment mechanisms for various actuators are roughly the same, the main difference being the different actuators. The adjustment mechanism uses a variety of general purpose control valves, which are beneficial for both production and use.
The actuator is a pushing device of the actuator, which generates a corresponding thrust according to the size of the control signal, and pushes the adjusting mechanism to operate. The adjusting mechanism is an adjusting part of the actuator. Under the action of the thrust of the actuator, the adjusting structure generates a certain displacement or rotation angle, and directly adjusts the flow rate of the fluid.
Electric actuators are an important part of the electric control system. It receives the 4~20mADC signal from the output of the motor controller and converts it into an appropriate force or torque to operate the adjustment mechanism to continuously regulate the flow of fluid in the pipeline during production. Of course, electric execution can also adjust the materials, energy, etc. in the production process to achieve automatic adjustment. The electric actuator is composed of an electric actuator and an adjustment mechanism. The part that converts the control signal from the electric controller into force or torque is called an electric actuator; and various types of control valves or the like The adjustment device is collectively referred to as the adjustment mechanism.
Electric actuators are simple and versatile according to different usage requirements. The simplest is the electromagnet on the solenoid valve, in addition to the use of the motor as a power component to push the adjustment mechanism. The most common type of adjustment mechanism used is the control valve, which is identical to the control valve used in pneumatic actuators.
