Abstract
The utility model relates to a nuclear power air tight door, which belongs to the technical field of special nuclear power facilities. The nuclear power air tight door comprises a door frame fixed at a door opening of a nuclear power building, a door leaf is mounted on one side of the door frame via hinges, a pressure reducing valve is mounted in the middle of the door leaf, a frame with the outer profile larger than the inner profile of the door frame is arranged on the periphery of a door panel of the door leaf, a door body which is protruded towards the direction of the door frame is disposed in the frame, the outer profile of the door body is smaller than the inner profile of the door frame, sealing strips are fixed on the periphery of the door body, and a locking handle is mounted on one side, which is far away from the hinges, of the door leaf. During usage, the door leaf is tightly closed via the handle, and the sealing strips are compressed and have sealing effect between the door leaf and the door frame. The pressure reducing valve can release pressure, balances pressure difference and leads the inner pressure and the outer pressure of the door to be identical basically, and accordingly requirements of nuclear power construction to the air tight door are feasibly met.
Description
Technical field
The utility model relates to a kind of hermatic door, and especially a kind of nuclear power air tight door belongs to the extraordinary facility technology of nuclear power field.
Background technology
Understand according to the applicant, nuclear power station needs to be provided with air tight door between each zone, and its major function is when guaranteeing unit operation, and each regional required force value (pressure differential is that 5000-500Pa does not wait usually) meets standard, and can carry out pressure release by reducing valve, reach pressure balance.
Existing product is difficult to satisfy nuclear power construction development a large amount of nuclear power stations has been accepted by present China of standard-required that air tight door improves constantly, air tight door is according to designing requirement in the special door, when for example pressure reduction is controlled at 5000-500Pa pressure reduction at different levels, air leakage rate is less than 10Nm3/h, after the logical limit pressurizing valve pressure release of door leaf simultaneously, should open conveniently.
The utility model content
The purpose of this utility model is: propose a kind of nuclear power air tight door that is exclusively used in nuclear power station, thereby satisfy the standard-required that nuclear power construction development improves constantly air tight door with simple and practical structure.
In order to reach above purpose, the utility model comprises the doorframe that is fixed on nuclear power building door opening place, and described doorframe one side is equipped with door leaf by hinge; Reducing valve is equipped with at the middle part of described door leaf; The door-plate periphery of described door leaf has gabarit greater than frame wide in the doorframe, inside have by protrude towards the doorframe direction and gabarit less than door body wide in the doorframe; Described door body border is fixed with weather strip; Described door leaf is equipped with lock handle away from a side of hinge.
During use, fasten door leaf by handle, the weather strip compression is played sealing function between door leaf and doorframe.Reducing valve can pressure release, and balance pressure reduction makes an external and internal pressure basic identical, thereby satisfies the nuclear power construction conscientiously to the air tight door requirement.
Description of drawings
Below in conjunction with accompanying drawing this product is further described.
Fig. 1 is the structural representation of an embodiment of the utility model.
Fig. 2 is the side sectional view of Fig. 1.
Fig. 3 bows to sectional view for Fig. 1's.
The specific embodiment
The nuclear power air tight door of present embodiment as shown in Figure 1, 2, 3, by the rectangle doorframe 1 that angle steel surrounds, the steel plate anchor 2 that the peripheral intervals of this doorframe 1 distributes and welds with it, particularly, its both sides are respectively equipped with upper, middle and lower three place's anchors 2, are respectively equipped with place's anchor up and down.The outer end bifurcated of steel plate anchor 2, thus swallowtail-shaped structure formed, can firmly build in nuclear power building door opening place.One side of doorframe 1 is equipped with door leaf 4 by the upper, middle and lower hinge 3 corresponding with homonymy anchor position.
Reducing valve 5 is equipped with at the middle part of door leaf 4, and the door-plate 4-1 periphery of door leaf 4 has gabarit greater than frame 4-2 wide in the doorframe, inside have by protrude towards the doorframe direction and gabarit less than door body 4-3 wide in the doorframe.Therefore the horizontal inner skeleton 4-4 spaced apart that has some between door-plate 4-1 and the door body 4-3 has the characteristics of light weight good rigidly.Door body 4-3 border is fixed with weather strip 6.Door leaf 4 is equipped with away from a side of hinge and is positioned at the upper, middle and lower lock handle 7 corresponding with homonymy anchor position, can constitute the locking relation with the bolt 8 of doorframe 1 correspondence position.
After the installation, close and when locking door leaf, weather strip plays desirable sealing function by compression between door leaf and doorframe by handle.Manually pressure release of reducing valve, the pressure reduction of balance door leaf inside and outside.Remove locking, door leaf just can be opened easily, very suitablely is applied to the nuclear power construction.
Except that above-mentioned enforcement, this product 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 this product invention requirement.
