coal minePneumatic regulated non pressure air doorIt is a key equipment in the mine ventilation system, which automatically opens and closes the air door and adjusts the air volume through a pneumatic control system. It has significant advantages such as high adjustment accuracy, fast response speed, and simple structure.

Adjust accuracy and response speed

The pneumatic non pressure regulating air door in coal mines can achieve precise adjustment of the air volume in the ventilation ducts. By adjusting the stroke of the actuator and changing the opening of the air damper, the air volume can be controlled with an accuracy of ± 1%. The response speed of this air damper is fast, which can achieve real-time adjustment of the air volume in the ventilation duct, which is of great significance for the stability and safety of the mine ventilation system.Opening form: Double fan synchronous opening and closing in opposite directions to balance wind pressure and reduce opening force

Suitable for roadway intake and return air roadway, connecting roadway, and monorail crane transportation roadway, suitable for monorail crane track penetration

Number of air door sets: One set, two channels, four fans. Common configuration, customizable

Open angle ≥ 90 ° to ensure smooth passage between the monorail crane and pedestriansAdjustable opening and closing time of 10-30s to avoid impact

structural characteristics

The structure of the pneumatic non pressure regulating air door in coal mines is relatively simple, mainly composed of components such as cylinders, pistons, and connecting rods. Easy maintenance and long service life. The door leaf is made of steel structure, with high strength, tight sealing, and low air leakage. Smooth closure, safe and reliable, bi-directional air isolation, no need to install reverse air doors. The work is simple and reliable, with both automatic and manual operation functions. The structure is simple and easy to maintain, and the two air doors can be locked through electrical means.

Scope of application

This air door is widely used in the ventilation system of coal mines, mainly in the main ventilation system, auxiliary ventilation system, local ventilation system, and gas drainage system of mines. In the main ventilation system of the mine, it can be used to adjust and control the air volume in the main ventilation duct, ensuring the stability and safety of the mine ventilation system.
