In fact, electric actuator refers to a kind of drive equipment that can show parallel lines or rotate fitness exercise. It uses some kind of drive power energy and works under some kind of manipulation data signal effect. Electric actuator applies liquid, steam body, power engineering or other power energy and converts it into drive effect according to motor, cylinder or other equipment. Its basic types are as follows There are three drive methods: part turn, multi turn and linear. The basic electric actuator is used to drive the gate valve to the full open or full close position, and the electric actuator used as the pressure regulating valve can make the gate valve to all positions accurately. Although most of the electric actuators are used to open and close the valve, the design scheme of the current electric actuator far exceeds the simple power switch function, including the position magnetic induction equipment Torque magnetic induction equipment, electric level protector, logic operation equipment, digital communication control module and PID module, etc., all of which are installed in a compact cabinet.

 

As more and more processing plants choose mechanical automation, and the actual operation of manual service is replaced by mechanical equipment or automatic machinery, it is stipulated that the electric actuator can have the page effect between the automatic control system and the thermal movement of gate valve molecules, and it is also stipulated that the electric actuator can improve the safety factor and ecological environment protection characteristics in work. In some dangerous places, the electric actuator equipment of automation technology can reduce the damage of workers. Some special valves require emergency opening or closing under special circumstances. Valve actuators can prevent further spread of danger and reduce plant losses. For some high-pressure and large-scale gate valves, the output torque of the electric actuator is very large. At this time, it is necessary to improve the mechanical efficiency of the electric actuator and apply the high output motor, so as to stabilize the actual operation of large-diameter valves. For some small torque gate valves, small and medium-sized electric valves are also used. Compared with the general type, they are lighter in weight and more compact in structure In addition, it has the advantages of perfect function.
