The pressureless damper is currently an ideal type of damper for coal mines in my country. It breaks the structural form of the old damper and cleverly uses the link balancing mechanism to convert the negative pressure acting on the damper into a negative pressure through the balancing mechanism. This kind of internal force makes the opening of the damper only related to the counterweight and the friction resistance of the door shaft.
Features of pressureless dampers
① The opening force of the damper is small, and the opening force has nothing to do with the size and direction of the wind pressure
② Two-way wind isolation, no need to install a reverse damper
③ Double-sided Sealed, small air leakage
④Smooth closing, safe and reliable
⑤Smart locking to prevent cross-wind and personnel crushing
⑥Simple system, energy saving, novel and beautiful structure.

Pressureless damper opening method is 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.
