Scope of application of explosion relief doors

Explosion relief door is a door set up to block the safety needs of explosion sources. The explosion relief door system should have good explosion resistance, flexible and reliable operation, and have fire and wind resistance performance. It can resist accidental explosions of external devices in industrial buildings, ensure the safety of personnel and ensure the integrity of internal equipment in industrial buildings. It shall not be damaged by the explosion shock wave, or the accidental explosion of indoor explosives, which will prevent the continuation of the explosion hazard. The explosion relief door is mainly composed of door frame, door leaf, hand wheel lock, load-bearing hinge and door closer. It can meet the requirements of explosion resistance, shock wave resistance, fire resistance stability, and integrity. The explosion relief doors are all external doors, and the explosion relief windows on the door leaf are all open outward. The explosion relief pressure value of the explosion relief window is controlled by the explosion relief bolt. The explosion-proof bolt is composed of bolts, waterproof washers, and aluminum alloy gaskets. The strength of the aluminum alloy gasket of the explosion-proof bolt corresponds to the explosion-proof pressure value of the explosion-proof window. Under the action of explosive pressure, the window sash can be opened under the impact of explosive airflow by deforming through aluminum alloy gaskets, in order to achieve the purpose of venting the explosion.

Scope of application of explosion relief doors:

Explosion relief doors are suitable for areas with potential explosion hazards. These types of buildings can be isolated or along the exterior walls of the building, with the aim of minimizing damage to the factory building. The explosion relief door system can provide indoor explosion pressure and can instantly release the critical pressure. The system function is to automatically open when the shock wave and pressure reach the initial set opening pressure of the explosion relief window when explosion occurs. Timely release the shock wave and pressure outdoors to avoid damage to buildings and other equipment, and maintain the integrity of the building structure. After a single use, the explosion relief door can still be closed and can be reused after testing.
