About China slack adjuster

There is an opening on the right side of the China slack adjuster, and there is a screw to adjust the internal tightness. Use a gong knife to twist left and right to adjust the tightness of the China slack adjuster.

China slack adjuster is mainly composed of support rails, transmission gears, return springs, one-way valves, rack plungers, throttle spools and shells, end caps, sealing rings and connectors. Rod. The shell and the connecting rod play the role of fixing the China slack adjuster and connecting the door leaf and the door frame. China slack adjuster is mainly used in commercial and public buildings.

The basic components of the hydraulic China slack adjuster include support rails, transmission gears, return springs, check valves, rack plungers, throttle spools and housings, end caps, sealing rings and connecting rods. The shell and the connecting rod play the role of fixing the China slack adjuster and connecting the door leaf and the door frame.

The working principle of China slack adjuster is that when the door is opened, the door body drives the connecting rod to move, drives the transmission gear to rotate, and drives the rack plunger to move to the right. The one-way valve ball on the left side of the plunger is opened under the action of oil pressure, and the hydraulic oil in the right cavity flows into the left cavity through the one-way valve. After the door opening process is completed, due to the spring pressure during the door opening process, the accumulated elastic potential energy is released, and the plunger is pushed to the left, driving the transmission gear and the connecting rod of the China slack adjuster to rotate to close the door.

During the release of the spring, the hydraulic oil in the left cavity of the China slack adjuster is compressed and the one-way valve is closed. The hydraulic oil can only flow out through the gap between the casing and the plunger, and return to the right cavity through the small hole and two flow passages equipped with a throttle valve core. Therefore, the hydraulic oil constitutes resistance to the release of the spring, that is, it achieves a buffer effect through throttling and controls the closing speed. The variable closing speed of different stroke sections can be controlled by adjusting the throttle valve on the valve body.
