Explosion-proof valve control box main structure and working principle 1, the main structure of the electric valve control box from the panel, control buttons, power switches, lights, AC contactor and other components. Can complete the valve opening and closing and release, clamping operation, status indication, motor overload protection and other functions. Electric eyeglass valve operation flow is: valve open valve closed 1. valve plate release in place 2. valve open in place 2
3. The valve plate is clamped in place 2. The basic principle of the explosion-proof valve control box When the valve is in the off position, turn on the power switch, the power indicator light is on, and the valve closing in-position indicator and clamping in-position indicator light at the same time. When it is necessary to open the valve, press the valve release button to loosen the forward rotation of the clamping motor, and then activate the release/clamping mechanism to release the action (clamping the position indicator off). After releasing the position, release the in-position stroke switch action ( Release indicator light is on), release the clamping motor and stop automatically after power off; then press the valve open button to open and close the motor forward rotation, drive the valve plate to turn over (the valve off indicator light goes out), the valve board opens When it is in place, the valve opens the position stroke switch action (the valve open position indicator light is on), the valve opens and closes the motor to stop running from the power off; then press the clamping button to loosen the clamping motor to reverse and drive the clamp to release the clamping mechanism Tight action (release of the in-position indicator lamp is off). After the clamp is in place, clamp the in-position stroke switch action (clamping the in-position indicator lamp on), release the clamping motor and shut off automatically to stop the operation and complete the automatic valve opening work process. Valves work from open to closed like the above.
