(Summary description)Working principle of electric valve electric device 1. Choose electric actuator according to valve type 1. Angular stroke electric actuator (rotation angle "360 degrees) is suitable for butterfly valve, ball valve, plug valve and other electric actuator output shaft rotation is less than one circle, that is less than 360 Degree, usually 90 degrees, realizes the valve opening and closing process control. This kind of electric actuator is divided into direct connection type and base crank type according to the different installation interface methods.  A) Direct connection type: refers to the form where the output shaft of the electric actuator is directly connected to the valve stem. B) Base crank type: refers to the form where the output shaft is connected to the valve stem through the crank. 2. Multi-turn electric actuator (rotation angle "360 degrees) is suitable for gate valves, globe valves, etc. The rotation of the output shaft of the electric actuator is more than one circle, that is, more than 360 degrees. Generally, it takes more than one circle to realize the valve opening and closing process control.  3. Straight stroke electric actuator (linear motion) is suitable for single-seat control valves, double-seat control valves, etc. The motion of the output shaft of the electric actuator is linear motion, not rotating.
