Anti-shock wave sealing valve The anti-shock wave airtight copy of the middle picture copy of the anti-shock wave door is mainly used for underground material warehouses and material distribution chambers to play an isolation role to prevent the shock wave and the flames and toxic gases generated from spreading to the external tunnels and discharged from the main return duct.
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 door. The outside of the door plate is equipped with a door suspension plate with an automatic opening angle. The ventilation volume of each group of valves is/the total ventilation volume is/the wind speed is/. When using the design, 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 the valve hanging plate of each group can be adjusted. The opening angle is fine-tuned to meet the optimal ventilation volume. When an explosion shock wave occurs in the warehouse and the residual pressure after attenuation is greater than the pressure, the valve hanging plate will be automatically closed and isolated from the outside world to prevent the explosion shock wave and the flames and toxic gases generated by the explosion from spreading to the external tunnels and being discharged from the main return duct.
There are two national standard models of anti-shock wave airtight doors. The size of the anti-shock wave airtight door of the model is * The maximum pressure that can withstand shock waves is / The size of the anti-shock wave airtight door of the model is * The maximum pressure that can withstand shock waves is
