Electric gate valves, how should the wiring all standing Industrial Valves factory technician for your detailed instructions: 1, confirm the working power supply. 2, make sure the valve opens. 3, confirm the valve control mode, switch model or simulation model. 4, confirm the valve actuator wiring electric gate valve used in different places on the basis of different water pressure difference or differential pressure at the ends of the damper ( Gate valve is closed) , torque limit institutions can be appropriately adjusted. On both ends of the electric gate valve gate direction when using hydraulic pressure or low differential pressure, torque should be transferred to the lower torque limit institutions, in the use of HZ series, z series or ZB and capsule mushroom spring pod 齄 pounds fold HZ series torque limit institutions, adjust the torque value requires, the greater the vice is small. More than a few series of adjustment. In adjusting lh-zd series valve electric actuator, to remove the side cover, adjust the torque limit institutions, unscrew the adjusting nut tight set screw, unscrew the adjusting nut, loosen knob torque spring, and on the position of the loose, then adjust the set screws tighten nut, hold the adjusting nut. Pay attention to the top of the set screw must be on the shaft groove, such as the top is not just on the shaft groove, as long as the adjusting nut to the direction of the compression spring a little turn, make it on the shaft groove set screws. Then put side cover, adjust the open valve. Such as torque limit agency action, the spring is too loose the close to the action. So that we can make the torque limit agencies work under low torque, ensure that electric gate valves in the stroke control mechanism failure, or for other reasons than torque, torque limit agencies and reliable action, and to cut off the motor power, to protect the valve from damage. Method, according to the wiring diagram connected line. 5, and began to debug according to control requirements, and to measure the signal. First how electric gate valve connection: six wire electric valve with fine by small electric actuators into the switch and adjustment, and is made up of drive switch control and signal feedback control. Six of six wire switch type electric valve terminals function as follows: 1, 2, 3 for the drive control, 4, 5, 6 for signal feedback control; 1, 2, connected, the valve is opened, while keeping the 4, 5, form a loop, feedback electric Industrial Valves in position signal; 1, 3 connected, the valve closing, while keeping the 4, 6, forming circuit, signal feedback electric valve shut in place. Adjustable six of six wire electric valve terminals function as follows: 1, 2 for electric drive control, can meet AC220V or DC24V power supply voltage ( If you need 380 v voltage otherwise specified) 。 3, 4 for the input signal control, can receive 4 - Or 0 to 20 ma current signal 10 v voltage signal. 5, and 6 for the output feedback control signal, May 4 - the corresponding feedback Or 0 to 20 ma current signal 10 v voltage signal, facilitate remote control operation. The electric valve driver is commonly used motor, voltage impact resistance. Solenoid valves are quickly opened quickly shut, generally used in small flow rate and pressure, require switching frequency bigger place of electric valve and vice. Electric valve opening of the door can control, states have open, closed, half-open half off, can control the medium inside the pipeline flow and solenoid valve can not reach the requirements. For electric valve through the above introduction, everyone how had certain understanding, wiring and working principle of electric valve is becoming more and more widely in engineering application of life, the valve installation technology requires us to learn a lot, also technical master, the more the more handy in future engineering practice.
