>It is an ideal type of underground damper in coal mines in my country at present. It breaks the structural form of the old damper and cleverly uses the link balance mechanism to control the impact on the damper. The negative pressure on the door is converted into an internal force through the balancing mechanism, so that the opening of the damper is only related to the counterweight and the friction resistance of the door shaft

>Opening method: manual operation. The pressureless damper is mainly used in the connection tunnel between the inlet and return air tunnels and the main inlet and return air tunnels in coal mines. When passing through the air door, the air door can be easily opened and automatically closed after letting go, effectively avoiding the occurrence of air flow short circuit and ventilation failure, and laying the foundation for coal mine standardization and modern management.
