Abstract
The utility model relates to a nuclear-power airtight fireproof door which comprises a door frame and a door leaf, wherein the door frame is fixed at a door opening of a nuclear-power building; the door leaf is fixed on one side of the door frame through a hinge; a pressure-reducing valve is mounted in the middle of the door leaf; the door leaf comprises a door plate; a door jamb, the outer profile of which is greater than the inner profile of the door frame, is arranged on the periphery of the door plate; a door body, the outer profile of which is less than the inner profile of the door frame, protrudes from the door plate toward the direction of the door frame; a sealing strip is fixed on circumference of the door plate; a fireproof swelling sealing element is fixed inside the door frame; and a locking handle is arranged on one side of the door leaf away from the hinge. By adopting the structure of the nuclear-power airtight fireproof door, the demands of a nuclear power station on the airtight function of a specific door and the fireproof function are both met.
Description
Technical field
The utility model relates to a kind of special door, and the airtight labeled door of especially a kind of nuclear power belongs to nuclear power special door technical field.
Background technology
Need to use special door in the construction of nuclear power station, requirement to its function is: (1) is when unit operation, guarantee the force value (being generally the different brackets between the pressure differential 5000-500Pa) that each zone is required, when needs enter certain room, can carry out the pressure release operation and reach pressure balance; (2) when breaking out of fire, possesses 1.5 hours fire resistance property.But, the present special door that does not still have to satisfy above-mentioned requirements.
The utility model content
The purpose of this utility model is: the problem at above-mentioned prior art exists proposes the airtight labeled door of a kind of nuclear power, to satisfy the requirement of nuclear power station to the special door function.
In order to reach above purpose, the airtight labeled door of nuclear power of the present utility model comprises the doorframe that is fixed on nuclear power building door opening place, and fixes on the door leaf of this doorframe one side through hinges fixing, and reducing valve is equipped with at described door leaf middle part; Described door leaf comprises door-plate, it is characterized in that, described door-plate periphery has gabarit greater than frame wide in the doorframe, described door-plate to the doorframe direction protrude gabarit less than doorframe in wide door body; Described door-plate border is fixed with weather strip; Described doorframe inboard is fixed with the fire prevention expansion sealing element; Described door leaf is equipped with lock handle away from a side of hinge.
The unique texture fitted seal bar and the lock handle of door leaf can guarantee the pressure reduction between each room; Reducing valve can be carried out the pressure release operation; The fire prevention expansion sealing element is met thermal expansion, can play fire insulation, every cigarette, heat insulation effect.
Further, described door-plate, frame, and a door body make by fire proofing material.
Further, described frame, and the door an external side composite fireproof plate is housed respectively.
Again further, described doorframe is surrounded by angle steel, the anchor that peripheral intervals distributes and welds with it.
Again further, described doorframe both sides are respectively equipped with upper, middle and lower three place's anchors, and described doorframe is respectively equipped with place's anchor up and down; The outer end bifurcated of described anchor forms swallowtail-shaped structure, is cast in nuclear power building door opening place.
Again further, described doorframe is also fixedlyed connected with the U-shaped connector that is cast in nuclear power building door opening place.
Again further, described lock handle has three, lays respectively at top, middle part, and the bottom of door leaf.
Adopt structure of the present utility model, not only can satisfy the requirement of nuclear power station, also can satisfy the fire-proof function of nuclear power station requirement the special door tight function.
Description of drawings
Below in conjunction with accompanying drawing the utility model is further described.
Fig. 1 is the structural representation of the utility model embodiment.
Fig. 2 bows to sectional view for Fig. 1's.
The specific embodiment
Embodiment
As shown in Figure 1, 2, the airtight labeled door of the nuclear power of present embodiment comprises the doorframe 1 that is fixed on nuclear power building door opening place, and is fixed on the door leaf 2 of these doorframe 1 one sides through hinge 3, and reducing valve 4 is equipped with at door leaf 2 middle parts; Door leaf 2 comprises door-plate 2-1, and door-plate 2-1 periphery has gabarit greater than frame 2-2 wide in the doorframe 1, door-plate 2-1 to doorframe 1 direction protrude gabarit less than doorframe 1 in a wide body 2-3; Door-plate 2-1 border is fixed with weather strip 5; Doorframe 1 inboard is fixed with fire prevention expansion sealing element 1-1; Door leaf 2 is equipped with lock handle 6 away from a side of hinge 3.
Door-plate 2-1, frame 2-2, and a door body 2-3 make by fire proofing material; Frame 2-2, and the door body 2-3 outside composite fireproof plate 2-4 is housed respectively.
Fire prevention expansion sealing element, fire proofing material, composite fireproof plate that present embodiment adopts are commercially available product.
During use, fasten door leaf by lock handle, the weather strip compression is played sealing function between door leaf and doorframe; The operation reducing valve carries out pressure release, and balance pressure reduction after external and internal pressure is identical, can be opened door leaf.When running into breaking out of fire, the fire prevention expansion sealing element is met thermal expansion, plays fire insulation, every cigarette, heat insulation effect.
The experiment proved that the tightness of present embodiment product is under pressure reduction is different brackets between the 5000-500P, air leakage rate is less than 10Nm
3/ h; Fire-protection rating is 1.5 hours.
In addition to the implementation, the utility model can also have other embodiments.All employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop on the protection domain of the utility model requirement.
