Description
Technical Field
The utility model relates to a people's air defense door technical field, concretely relates to explosion vent for people's air defense.
Background
The entrance and exit of the civil air defense project are usually the weakest parts of the whole civil air defense facility, and an explosion-proof door is generally arranged at the entrance and exit of the civil air defense project to prevent the damage of shock waves generated by explosion in wartime. Explosion vents generally comprise a door frame, a door leaf, a hinge and a circular latch, the door leaf usually consisting of a front panel and a rear panel, between which a concrete block is filled. The front panel, the rear panel and the concrete block are in rigid connection, and when the front panel, the rear panel and the concrete block are subjected to a strong impact wave, the matching among the partition walls is easy to loose. When continuous explosion happens, all parts of the explosion-proof door collide with each other, so that the door leaf is damaged or even disintegrated, and the protection function is lost.
At present, the door leaf of explosion vent is used in current people's air defense is made mostly to adopt the steel sheet, and the bearing strength of people's air defense door leaf has certain requirement, but because the defect of steel sheet itself, if: the surface is easy to wear and tear, and intensity is low, and life is short to oxidation resistance is poor, can produce rust for a long time, destroys structural strength easily, reduces life, and blast shock wave resistance, leakproofness are lower and consumptive material consuming time many with high costs.
