No Pressure Ventilation Door (Balanced pressure ventilation door) is mainly used for underground outlet inlet lane and the main outlet inlet air lane

No Pressure Ventilation Door Introduction :

No Pressure Ventilation Door (Balanced pressure ventilation door) is mainly used for underground outlet inlet lane and the main outlet inlet 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, it breaks the old traditional damper structure for a long time.It cleverly put on the pressure acting on the throttle through the equilibrium structure to convert it into a force, fully demonstrated the unique air structure.

Non pressure air door is simple to use, safe and reliable, highly evaluated by experts and users, is currently used in the airway of an alternative.

 

No Pressure Ventilation Door Main Structure:

Non pressure air door is composed of a door frame,door leaf, connecting rod balancing mechanism and a weight  interlocking mechanical etc.

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  has nothing to do with wind 

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.

Working principle:
The two air doors were opened in two directions.To realize linkage through the connecting rod and the support arm.Change the length of the connecting rod can adjust the air tightness.
