Valve control loop power transmission: first closing rotary switch, and the contact of rotary switch is connected, the second indicator light obtain it is electric bright,
Then indicate that valve control loop charges；
Startup power supply main contactor: start button, the coil energized action of power supply main contactor, power supply main contactor are pressed
The first normally opened contact be closed self-insurance, three main contacts of power supply main contactor are closed at, and are the contactor of valve open/close
KM1 and KM2 major loop provides power supply；Second normally opened contact of power supply main contactor is closed, and third indicator light obtains electric bright, expression electricity
Source main contactor power transmission；
It the valve opening of electrically operated valve and closes valve: closing the second control fuse, open and close valve control loop has electricity at this time, can be with
Carry out corresponding open and close valve operation:
Valve opening working principle: valve opening button is pressed, the normally opened contact closure of valve opening button, the coil of valve opening contactor obtains electric
Movement, the normally opened contact of valve opening contactor are closed self-insurance, and motor-driven valve motor obtains electric operation, and valve is rotated to open direction,
And then valve is opened, when valve is opened to fully open position, the normally-closed contact of valve opening process travel switch LS1 is disconnected, and valve opening connects
Three main contacts of the coil losing electricity of tentaculum, valve opening contactor simultaneously switch off, the stalling of motor-driven valve motor, and valve, which terminates, to be opened,
Simultaneously valve opening process travel switch LS1 normally opened contact closure, valve standard-sized sheet indicator light obtain it is electric bright, indicate electrically operated valve be in standard-sized sheet
State；If valve opening process travel switch LS1 failure, the normally-closed contact of valve opening process travel switch LS1 is not during valve opening
It can open, the coil of valve opening contactor does not turn off, and motor-driven valve motor is still operating, so that the torque on output shaft is more than
The limit switch of torque position-limit mechanism, then the valve opening torque limit switch LS3 movement on electrically operated valve, opens valve opening torque limit
The normally-closed contact for closing LS3 disconnects, and power supply main contactor power-off release, three main contacts of power supply main contactor are simultaneously switched off, opened
The major loop of valve contactor powers off, and has cut off the power supply of motor-driven valve motor, then motor stalls, and valve opening movement terminates, and plays
It transfinites to the valve opening of electrically operated valve/journey protection；
It closes valve working principle: pressing ShiShimonoseki valve button, close the coil energized action of valve contactor, close the normally opened touching of valve contactor
Point closure self-insurance, motor-driven valve motor energized action, valve start to rotate to the direction of closing, and valve is closed, when valve pass is arrived
When closed positions, valve process travel switch LS2 movement is closed, the normally-closed contact for closing valve process travel switch LS2 disconnects, and closes valve contact
The coil blackout of device, three main contacts for closing valve contactor simultaneously switch off, the stalling of motor-driven valve electric motor circuit breaking, and valve, which terminates, to close
It closes, while closing the normally opened contact closure of valve process travel switch LS2, the coil energized action of intermediate relay makes intermediate relay
The normally opened contact of device is closed, and valve closes indicator light entirely, and to obtain electric light bright, indicates that valve is in full off state；During closing valve, once
When closing valve process travel switch LS2 failure, the normally-closed contact of travel switch LS2 cannot be disconnected, and the coil for closing valve contactor is continuous
Electricity closes valve contactor and charges always, and motor-driven valve motor rotates always, closes valve torque limit switch LS4 movement, limit switch
The normally-closed contact of LS4 disconnects, and the coil blackout release of power supply main contactor, three main contacts of power supply main contactor break simultaneously
It opens, and then the major loop for closing valve contactor is made to disconnect power supply, cut off the power supply of motor-driven valve motor, motor-driven valve electric motor circuit breaking
Stalling is closed valve events and is terminated, and/journey protection of transfiniting to the pass valve of electrically operated valve is played.
Beneficial effect compared with the existing technology is that using the above scheme, the utility model passes through five installed in cabinet door
A indicator light can clear indication go out to control valve opening, the close valve state of electric cabinet electric elements inside and electrically operated valve, in order to
Staff timely understands electrically operated valve and control electric cabinet operating condition, practical；Pass through valve opening on electrically operated valve
Torque limit switch LS3 normally-closed contact closes valve torque limit switch LS4 normally-closed contact and connects with the coil of power supply main contactor company
It connects, as valve opening process travel switch LS1 or pass valve process travel switch LS2 failure, motor-driven valve motor is caused to be transported always
Turn up to the torque on output shaft to be more than the limit switch of torque position-limit mechanism, then valve opening torque limit switch LS3 or pass valve
Torque limit switch LS4 movement, the coil blackout release of power supply main contactor, three main contacts of power supply main contactor break simultaneously
It opens, is that motor-driven valve motor stops operating, to protect motor-driven valve motor, electrically operated valve is avoided to open or close the excess of stroke,
Prevent electrically operated valve from breaking down.
It should be noted that above-mentioned each technical characteristic continues to be combined with each other, the various embodiments not being enumerated above are formed,
It is accordingly to be regarded as the range of the utility model specification record；Also, it for those of ordinary skills, can be according to above stating
