How to adjust the door closing force

Answer:

Adjustment methods and precautions: see pictures in the picture, generally in the side of the door closer to the side of the regulation of the valve is marked 1.2, speed 1 block is to adjust the door opening angle from 90 degrees to 20 degrees between the closing speed, speed 2 Block is to adjust the door opening angle from 20 degrees to 0 degrees that is the door completely closed the speed of the trip. Adjust the valve if the screw tightening (clockwise adjustment) is to slow down the speed, that is, closing the door close the door to adjust the power. If the valve screw loose (counterclockwise adjustment) is the speed becomes faster, that is, increase the closing door closing force. Adjust the amplitude must be controlled in a small range, and each adjustment are tested door fan strength is appropriate, if the amplitude is too large may screw off, resulting in door closers oil spill.

Door closers to adjust the closing speed is through the two hydraulic valve independent control of two door closers closing speed for full hydraulic control.

Adjust the closing force of the closing door is to adjust the closing speed, the strength of the fast when the speed is small, the door closers close the speed of the slow.
