Description
Technical field
The present invention relates to a kind of fire resistant doorsets, more particularly to a kind of fire resistant doorsets smog retracting device.
Background technology
From three miles of island accidents of last century the eighties to the Chernobyl accident of the nineties, and in March, 2011 hair
Raw Fukushima, Japan the first nuclear power station leakage accident, people progressively recognize the importance of nuclear safety.Along with the generation of fire,
A large amount of flue gases with radioactive substance can be produced, this can produce grave danger to the life security of people.Fire resistant doorsets are a kind of
Very important fire equipment, can effectively prevent spreading for the intensity of a fire, but the smog for leaking cannot be played and hindered completely
Every effect, it is therefore necessary to study it is a kind of can be to the device that be reclaimed of smog revealed from nuclear power station fire resistant doorsets.
The content of the invention
It is an object of the invention to provide a kind of nuclear power station fire resistant doorsets smog retracting device, enhance between door leaf and doorframe
Sealing, prevents the leakage of smog.
The object of the present invention is achieved like this：A kind of nuclear power station fire resistant doorsets smog retracting device, including doorframe, on doorframe
The door leaf opened in being provided with, the outside of doorframe is provided with range hood, and the range hood offers external groove towards the side of doorframe,
The bottom of the range hood is connected with turbocharger, and the smoking pipeline of the worm wheel pressure booster is connected with the external groove,
The smoke discharging pipe of worm wheel pressure booster is connected on air accumulator, and range hood is divided into outer frame body and internal frame body by the external groove, described
Outer frame body is fitted in doorframe lateral surface, and the surface of internal frame body, the external groove and doorframe medial surface are fitted in during door leaf closing
Between form smoking gap.
When nuclear power station occurs accident smog leakage occurs, smog can be leaked from crack between a door and its frame, and the smog of leakage can be from
Smoking gap enters external groove（Smoking passage）, now worm wheel pressure booster siphons away the smog in smoking passage, and is stored in
In gas tank.Compared with prior art, the beneficial effects of the present invention are, the present invention by the outside of doorframe install range hood,
Enhance the sealing between door leaf and doorframe, even if while have a small amount of smog leakage also can by turbocharger absorb walk storage
Exist in air accumulator, improve the security that fire resistant doorsets are used.The present invention can be used in nuclear power station.
In order to further enhance sealing when range hood is used, offered on the doorframe and external groove cooperation
Inner groovy, the width of the inner groovy is equal with the width of outer frame body, and doorframe lateral surface is divided into inside casing and outer by the inner groovy
Frame, the width of the inside casing is equal with the width of external groove, and the outer frame body insertion inner groovy is set, and inside casing insertion external groove sets
Put.The sealing of range hood is further enhanced by setting labyrinth seal face.
In order to ensure that smog can be siphoned away in time, the depth of the inner groovy is less than external groove.To ensure the smog of leakage
Can enter in external groove.
In order to further enhance the sealing between range hood and door leaf, the internal frame body surface of the range hood is provided with close
Strip of paper used for sealing.
Brief description of the drawings
Fig. 1 is schematic structural view of the invention.
Fig. 2 is doorframe structure schematic diagram in the present invention.
Fig. 3 is front view of the present invention.
Fig. 4 for this along Fig. 3 A-A to sectional view..
Wherein, 1 doorframe, 1a inner groovies, 2 door leafs, 3 range hoods, 3a outer frame bodies, 3b external grooves, 3c internal frame bodies, 4 turbines increase
Depressor, 5 air accumulators, 6 smoking gaps.
Specific embodiment
A kind of nuclear power station fire resistant doorsets smog retracting device as Figure 1-4, including doorframe 1, are provided with interior opening on doorframe 1
Door leaf 2, the outside of doorframe 1 is provided with range hood 3, and range hood 3 offers external groove 3b, range hood 3 towards the side of doorframe 1
Bottom be connected with turbocharger 4, the smoking pipeline of worm wheel pressure booster is connected with external groove 3b, the smoke evacuation of worm wheel pressure booster
Pipeline is connected on air accumulator 5, and range hood 3 is divided into outer frame body 3a and internal frame body 3c by external groove 3b, offered on doorframe 1 with outward
The depth of the inner groovy 1a that groove 3b coordinates, inner groovy 1a is less than external groove 3b, the width of inner groovy 1a and the width of outer frame body 3a
Degree is equal, and the lateral surface of doorframe 1 is divided into inside casing and housing by inner groovy 1a, and the width of inside casing is equal with the width of external groove 3b, outward
Framework 3a insertion inner groovies 1a is set, and inside casing insertion external groove 3b is set, and the table of internal frame body 3c is fitted in during the closing of door leaf 2
Face, forms smoking gap 6 between external groove 3b and the medial surface of doorframe 1, the internal frame body 3c surfaces of range hood 3 are provided with sealing strip.
When nuclear power station occurs accident smog leakage occurs, smog can be leaked from crack between a door and its frame, and the smog of leakage can be from
Smoking gap 6 enters external groove 3b（Smoking passage）, now worm wheel pressure booster siphons away the smog in smoking passage, and is stored in
In air accumulator 5, the smoking gap 6 between external groove 3b and the medial surface of doorframe 1 is effectively guaranteed smog when leaking, can
Into smoking passage so that turbocharger 4 can in time siphon away smog；The inner groovy 1a of setting causes outer frame body 3a in insertion
During inner groovy 1a, the sealing that labyrinth seal passage further enhances range hood 3 is formed.
The invention is not limited in above-described embodiment, on the basis of technical scheme disclosed by the invention, the skill of this area
Art personnel are according to disclosed technology contents, it is not necessary to which performing creative labour just can make one to some of which technical characteristic
A little to replace and deform, these are replaced and deform within the scope of the present invention.
