Adjustment of the valve electric device

After the electric actuator is assembled with the valve, the torque controller, stroke controller, and opening indicator must be adjusted separately before use
Before adjustment, it is necessary Check whether the potentiometer on the opening indicator has been disengaged (loosen the set screw of the gear on the potentiometer shaft to prevent damage. Check the rotation direction of the motor and whether the control circuit is correct to prevent the motor from running out of control.
The torque controller, stroke controller and opening indicator of the electric actuator are the same, so the adjustment methods are the same.


Adjustment of the torque controller

Factory The torque has been adjusted according to the user's requirements, and generally no further adjustment is needed. If you need to change the setting value, you can rotate the adjustment shaft of the cam to the corresponding scale, first adjust the closing direction, and then adjust the opening direction.

Adjustment of the process controller

Adjustment of the fully closed position
)
Close the valve tightly by hand
)
Use a screwdriver to press down the push rod and The rotation is stuck, so that the driving pinion (eight gears) and the counter ones gear are completely disengaged
)
Press the closing arrow to rotate the closing adjustment shaft until the closing cam moves
)
Rotate the ejector rod to its original position so that the driving pinion (eight gears) meshes correctly with the ones gears on both sides of the counter. At this time, be sure to use a screwdriver to rotate the closing adjustment shaft to ensure its correct meshing.
Adjustment of the fully open position
)
Open the valve to the required position manually
)
Press down the ejector pin and turn it to lock the driving pinion ( Eight gears) are completely disengaged from the counter ones gear
)
Press the opening arrow to rotate the opening adjustment shaft until the opening cam moves
)
Turn the push rod back to its original position position, so that the driving pinion (eight gears) meshes correctly with the units gears on both sides of the counter. At this time, be sure to use a screwdriver to rotate the opening adjustment shaft to ensure that it meshes correctly.


Adjustment of the opening indicator

After adjusting the torque and stroke, adjust the on-site opening indicator and remote potentiometer. The adjustment method is as follows
)
Move the number of turns adjustment gear to the required number of turns position
)
Hang up the potentiometer gear, tighten the potentiometer fixing nut and determine the set screw of the potentiometer gear is loosened
)
Close the valve manually or electrically and face the indicator plate to observe the direction of rotation of the potentiometer gear
)
Turn the closing indicator plate so that the closing mark is aligned with the pointer
)
Turn the potentiometer shaft close to the end position according to the observed direction of rotation of the potentiometer gear, and tighten the set screw
)
Electrically or manually operate the valve to the fully open position, and hold The closing dial does not move, and the opening indicator dial is turned to align the opening mark with the pointer
Check the flashing light of the electrically operated valve. The red light flashes when the valve is open, and the red light stays on when it is fully open. The green light flashes when the valve is closed. , the green light stays on when it is closed in place.
