Abstract
The utility model provides a hanging deck type explosion blast proof movable door. A doorframe wall and a movable door are formed by the reinforced concrete pouring. A hinge ear is connected to a steel doorframe and is hinged with the movable door. A ventilation hole is provided perpendicular to the movable door surface. The outside of the ventilation hole is provided with at least one hanging deck whose upper end is hinged with a hinged supporter. The movable door is provided with four to eight ventilation holes whose longitudinal sections are conical. The big end of the ventilation hole is on the inside surface of the door and the small end is on the outside surface of the door. The ventilation hole and the hanging deck are matched and sealed. The sealing surface of the hanging deck is stuck with a rubber deck which closely abuts with the movable door surface when closing. The center position of the movable door corresponding to the lap of the hanging deck is fixed with a spacing seat whose angle of spacing deck is the same with the opening angle of the hanging deck. The undersurface of the spacing plate is fixed with a rubber pad. The outside surface of the doorframe wall is wrapped with steel door frame whose four corner places are welded with anchor embedded parts. The side of the steel door frame near the doorframe hinge ear is connected with a hinge ear embedded steel deck which crosses the anchor embedded part and is anchored in the doorframe wall. The utility model solves the problems that the hanging deck air leakage is easy to happen when the ventilation hole sealing, the opening angle of the hanging deck is difficult to control, and the doorframe is easy to loose.
Description
Technical field
The utility model relates to a kind of civil air defense constructions and installations safeguard, and particularly a kind of civil air defense constructions and installations is prevented the deflagration wave valve.
Background technology
Anti-deflagration wave valve generally is installed in the ventilation oral area of civil air defense constructions and installations diffuser casing, is used for weakening wartime the shock wave invasion, avoids damaging ventilation equipment.Existing hanging deck formula is prevented the deflagration wave valve, and door frame wall and valve are built by steel concrete and formed, and connects the hinge ear on the doorframe, and hinged with valve, have gravity vent perpendicular to the valve surface, the gravity vent outside is provided with hanging deck, the hanging deck upper end is hinged with free bearing, and the hanging deck bottom is unsettled at ordinary times opens; Under the shock wave effect, hanging deck covers gravity vent, realizes sealing function.The defective of this anti-deflagration wave valve: total four rectangle gravity vents up and down on the valve, pass is of a size of 270 * 190 (mm), and the hole is big, number makes sealing difficulty increase less, occurs the problem of leaking out when hanging deck is closed easily; Its two, the opening angle of the hanging deck bottom is wayward; In addition, also has the easily loosening problem of doorframe.
The utility model content
The purpose of this utility model provides the anti-deflagration wave valve of a kind of hanging deck formula, occurs the problem of leaking out when solving the sealing of gravity vent and hanging deck easily; Solve the uppity problem of hanging deck opening angle; Also solve the easily loosening problem of doorframe.
The technical scheme of the anti-deflagration wave valve of the utility model hanging deck formula: door frame wall and valve are built by steel concrete and are formed, connect the hinge ear on the steel door frame, and it is hinged with valve, have gravity vent perpendicular to the valve surface, the gravity vent outside is equipped with at least one hanging deck, the hanging deck upper end is hinged with free bearing, it is characterized in that:
Have four to eight gravity vents on the valve, the vertical section of its gravity vent is taper, holds greatly in the door inboard, and small end is at outer side of door, gravity vent and hanging deck fitted seal, and the hanging deck sealing surface posts rubber tile, and when closing and valve surface fits tightly;
Valve is fixed with limit base with respect to the centre position of the hanging deck bottom, and the limiting plate angle of limit base is identical with the hanging deck opening angle, and the limiting plate soffit is fixed with rubber cushion;
Door frame wall is surrounded by steel door frame outward, and the steel door frame four corners position is put welding grasp built-in fitting, and steel door frame connects hinge ear pre-embedded steel slab near doorframe hinge ear one side, and hinge ear pre-embedded steel slab and grasp built-in fitting intersect and be anchored in the door frame wall.
Above-mentioned gravity vent is corner cut rectangular opening, round rectangle hole, elliptical aperture or circular hole.
Beneficial effect: the structure of gravity vent and connection and reasonable arrangement, when hanging deck places the installation site, rotate flexibly, open voluntarily, when hanging deck was closed, the valve surface fitted tightly with the hanging deck rubber tile, occurred the problem of leaking out when having solved the sealing of gravity vent and hanging deck easily.Valve is fixed with limit base with respect to the centre position of the hanging deck bottom, and the limiting plate angle of limit base is identical with the hanging deck opening angle, and the limiting plate soffit is fixed with offset plate, has solved the uppity problem of hanging deck opening angle.Doorframe hinge ear, steel door frame, grasp built-in fitting, hinge ear pre-embedded steel slab weld together securely, have solved the easily loosening problem of doorframe.
The anti-deflagration wave valve of this hanging deck formula is when wind speed 8m/s, and the dynamic load design pressure is 0.15-0.30Mpa (150-300KN/m
2), ventilation is respectively 2000,3600,5700,8000,11000,14500 (m
3/ h).The utility model is in opening at ordinary times, and do time spent and rapidly close being subjected to shock wave wartime, and shock wave energy is blocked in the outside of valve, and after shock wave disappeared, valve was opened the recovery ventilation function, is applicable to underground civil air defense constructions and installations.
