No Pressure Ventilation Door Introduction
No Pressure Ventilation Door (Balanced pressure ventilation door) is mainly used for underground into back into
the lane and the main return air lane between each contact, which is the substitute for all air door.
The damper is an ideal air door of our country coal mine at present,
and is mainly used for underground into return air lane and the main return air lane between each contact which,
it breaks the old traditional damper structure for a long time.
It is mainly used in underground into the return airway and into the return airway main liaison between each lane,
it is breaking the long tradition of old-fashioned structure type throttle.
It cleverly put on the pressure acting on the throttle through the equilibrium structure to convert it into a force,
clearly showing the damper structure is unique, easy to use, safe and reliable by experts and users highly rated,
is the wind Lane used throttle alternatives.
No Pressure Ventilation Door Main Feature
1、The ventilation door opening force is small, and the size of the opening force of the
wind pressure and wind has nothing to do;
2、Two-way isolation, wind leakage air volume is small, no need to reverse damper;
3、Steel structure, simple structure, strong and durable;
4、Close the steady, safe and reliable;
5、Good fireproof performance, can effectively prevent the possibility of fire belt transport lane,
prevent fire and other harmful gases into the roadway;
6、Pressure balance type damper is good sound operation, also can power operation,
such as add a set of control system, can realize the air door automatically open;
7、Between two air door which can realize mutual atresia.
