Gravity Damper
The basic structure of a gravity damper consists of a flap, a bearing, and a control rod. Among them, the flap is the main body of the windlock, made of metal or plastic. The bearing is fixed under the flap to bear the weight of the flap and gravity force. The control rod is the intermediate object connecting the bearing and the flap, mainly playing the role of support and adjustment.
Overview
Working Principle:
When the air enters the inside of the flap from the air outlet, the force of the airflow makes the flap open automatically until it reaches the maximum opening angle. When the airflow stops or decreases, the flap closes automatically due to gravity. In a closed room, the working principle of gravity air damper can be utilized to realize air circulation by controlling the opening and closing of doors and windows.
