Electric pneumatic - valve structure of its composition and the operation mode of the machine

Electric pneumatic - valve structure with the operation of the motor, electric pneumatic control valve is mainly composed of body, sleeve, disc, stem and other parts. Sleeve and the disc drive with orifice by rotary disc in the seat to change flow area, regulate traffic. With ZKJ type or other type electric quarter-turn actuators can realize remote control and automatic control. Electric pneumatic - valve widely used in feed line to adjust flow using, also can be used in the oil pipeline. Electric pneumatic control valve of the motor running internal heat can cause thermal protection, electric pneumatic regulator to stop work; Due to the motor must pass through multiple reduction to output torque, so the speed is not fast, in some requiring quick opening and closing is not applicable, big torque and high speed, is a more difficult to solve the contradiction between; Because of the moving parts, relatively prone to failure, especially in adjusting the working condition of frequent, easy to produce motor thermal protection, gear damage, module of fault, thyristor burnt under this condition, it is better to choose pneumatic pneumatic regulator is good.
