Closed door closing speed regulation and the matters needing

The door closer after using for some time, the closing speed will change, are also said to be close to other strength is one thing to say. That is the strength adjusting closers closers speed regulation, and the party power is simple fast, small power is slow.
Adjust the door closers speed is generally independent of control two closed door closing speed by two for the whole hydraulic, hydraulic control to control the speed.
Door closer, speed adjustment, specific operation
1、If the valve is tightened (clockwise), it will slow down, that is to say, the door closing power will be smaller.
2、If the valve screws loosen (counterclockwise adjustment) is faster, which is increasing while increasing the strength of closed door closers closers closed speed. So we must be in the regulation of amplitude control in small amplitude, and each adjustment test of door efforts is appropriate, if the amplitude is too large may screw spin off, causing the door closer leaking.
Closed note speed regulation device
We are in a cross side door closers are marked as 1.2 regulating valves, 1 speed gear is adjusting the door open angle from 90 degrees to 20 degrees between the closing speed, speed 2 gear is regulating the door open angle from 20 degrees to 0 degrees is the door completely shut down stroke speed.
