Anti-shock wave Shock wave doors are divided into anti-shock wave sealed doors and anti-shock wave valves. Anti-shock wave airtight doors and anti-shock wave valves are used together.
Anti-shock wave doors are mainly used in underground material warehouses and material distribution chambers. They play an isolation role to prevent flames and toxic gases generated by shock waves from spreading to external tunnels and are discharged from the main return air duct.
Shock wave resistant closed door consists of door frame, door leaf, leaf, locking device and other components.
The door frame is made of unequal angle steel assembled and welded frame components.
The door leaf is welded by an arc-shaped shell plate, a tic-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 a glyph-shaped cross-section rubber strip seal.
Compared with anti-shock wave sealed doors, the upper part of the door leaf is equipped with three sets of ventilation valve devices, that is, there are three sets of ventilation holes with a common diameter on the bottom plate of the valve, and the outside of the valve plate is equipped with a valve suspension plate with an automatic opening angle. The ventilation volume of each group of valves is /, the total ventilation volume is /, and the wind speed is designed according to /. When used, the number of ventilation valve groups can be determined according to the air volume required by the underground blasting material library and the total return air duct negative pressure value, and each group can be adjusted. The opening angle of the group valve hanging plate 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.
