Vent window 1. It refers to the special steel window that the explosion relief bolt of the explosion relief window can fall off automatically when the air pressure difference inside and outside the building reaches a certain value, and the explosion relief window can open automatically to release gas and reduce the internal air pressure to protect the safety of people and property in the building. 2. The explosion relief window adopts steel (aluminum alloy, stainless steel) window frame and is equipped with special hinges, explosion relief devices and other hardware accessories;The window sash can automatically open under a certain pressure to discharge the pressure;The area of explosion venting window can be used as the explosion venting area, which can solve the contradiction of insufficient explosion venting wall area and explosion venting roof area in some special cases.The explosion relief window can be reused, and can be opened or closed normally after explosion relief. 3. Explosion relief windows are usually light pressure relief windows (weighing no more than 60KG/㎡) used in industrial and civil plants, boiler rooms, dangerous goods warehouses and spaces with potential explosion risks.The explosion relief pressure is usually 20-40PSF. When explosion or combustion occurs inside the building, the gas pressure in the room will rise sharply. The explosion relief window will open the window and release the pressure through the explosion relief accessories or devices to control the explosion or minimize the damage. 4. The quantitative explosion relief pressure value of the explosion relief bolt dynamically controls the release pressure. 5. There are usually thermal insulation type explosion venting windows and lighting type explosion venting windows.
6. It is generally divided into three types: A-type explosion venting window, B-type fragile explosion venting light window and C-type fragile explosion venting skylight.
