Underground coal mine anti-shock wave door Anti-shock wave door is constantly changing throughout the year, night and day are constantly changing, the pace of the times is constantly changing,,,,, (anti-shock wave door, coal mine anti-shock wave door) is passed down from generation to generation, one generation succeeds another, the development of the times This is the general trend! Shandong Sheng Coal Mining Machinery is slowly standing up in such an era! Our company has gone through ups and downs for decades! From being young and ignorant, we have stumbled to the forefront of the industry. Only we know the hardships along the way! Shandong Sheng Coal Mining Machinery only wants to make high-quality anti-shock wave doors that truly belong to you! To buy anti-shock wave doors, come to Shandong Sheng Coal Mining Machinery! Manager Wang’s mobile phone is waiting for your call!
According to their different use environments, mine doors can be divided into waterproof closed doors used in the main drainage pump room, fire-proof fence doors used in substations, and anti-shock wave doors used in warehouses! Anti-shock wave doors are divided into anti-shock wave sealed doors and anti-shock wave valves. The two sets of doors must be used together!

Anti-shock wave door is mainly used in underground material warehouses and material distribution chambers. It plays an isolation role to prevent the flames and toxic gases generated by the shock wave from spreading to the external tunnels. Return air duct discharge.
Shock wave resistant closed door consists of door frame, door leaf, leaf, locking device and other components.
The door frame is a welded frame component of unequal angle steel.
The door leaf is welded by an arc-shaped shell plate, a well-shaped rib plate and a channel steel ring beam.
The lower dumpling page is supported by one-way thrust ball bearings.
The locking device is a locking shaft and handle rotation type.
The sealing method adopts glyph cross-section rubber strip sealing.
Compared with anti-shock wave sealed doors, anti-shock wave valves are equipped with three sets of ventilation valve devices on the upper part of the door leaf, that is, there are three sets of ventilation holes with a common diameter on the bottom plate of the valve, and a valve hanging plate with an automatic opening angle is installed on the outside of the valve plate. The ventilation volume of each group of valves is , the total ventilation volume is , and the wind speed is designed according to The opening angle of the panels is fine-tuned to meet the optimal ventilation volume. Once an explosion occurs in the warehouse, after the shock wave has attenuated, as long as the residual pressure is greater than 1, the valve hanging plate will automatically close under pressure and isolate it from the outside world, preventing the explosion shock wave and the flames and toxic gases generated by the explosion from spreading to the external tunnel. It is discharged from the main return air duct.
