The invention discloses a kind of nuclear power station fire resistant doorsets smog retracting devices in fire resistant doorsets field, including doorframe, the door leaf opened in being equipped on doorframe, the outside of doorframe is equipped with range hood, the bottom of range hood is connected through flue with the input terminal of turbocharger, the output terminal of turbocharger is connected with air accumulator and is connected, range hood is " mouth " character form structure, the outline border size of range hood is more than doorframe channel size, the inside casing size of range hood is less than doorframe channel size, door leaf is fitted at closing time on range hood medial surface, the present invention in the outside of doorframe by installing range hood, enhance the leakproofness between door leaf and doorframe, simultaneously even if having a small amount of smog leakage also can by turbocharger absorb walk to be stored in air accumulator, improve the security that fire resistant doorsets use, available in nuclear power station.
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
It is sent out from three miles of island accidents of last century the eighties to the Chernobyl accident of the nineties and in March, 2011
Raw Fukushima, Japan the first nuclear power station leakage accident, people progressively recognize the importance of nuclear safety.With the generation of fire,
A large amount of flue gases for carrying radioactive substance can be generated, this can generate grave danger to the life security of people.Fire resistant doorsets are a kind of
Very important fire equipment, can effectively prevent the sprawling of the intensity of a fire, but can not play complete resistance for the smog of leakage
Every effect, it is therefore necessary to study a kind of device that can be recycled to the smog revealed from nuclear power station fire resistant doorsets.
The content of the invention
The object of the present invention is to provide a kind of nuclear power station fire resistant doorsets smog retracting devices, enhance between door leaf and doorframe
Leakproofness 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 equipped with, the outside of doorframe are equipped with range hood, and the one side of the range hood towards doorframe offers external groove,
The bottom of the range hood is connected with turbocharger, and the smoking pipeline of the turbocharger is connected with the external groove,
The smoke discharging pipe of turbocharger 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 formed smoking gap.
When accident, which occurs, for nuclear power station smog leakage occurs, smog can leak at crack between a door and its frame, and the smog of leakage can be from
Smoking gap enters external groove（Smoking passage）, turbocharger siphons away the smog smoked in passage at this time, 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 leakproofness between door leaf and doorframe, while even if there is a small amount of smog leakage also can absorb storage by turbocharger
There are the securities in air accumulator, improving fire resistant doorsets and using.The present invention can be used in nuclear power station.
In order to further enhance leakproofness when range hood uses, 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 is set
It puts.By the way that labyrinth seal face is set to further enhance the leakproofness of range hood.
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
It can enter in external groove.
In order to further enhance the leakproofness 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.

Fig. 2 is doorframe structure schematic diagram in the present invention.
Fig. 3 is front view of the present invention.
Fig. 4 is this sectional view along A-A along Fig. 3..
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 shown in Figs 1-4 including doorframe 1, is equipped with interior open on doorframe 1
Door leaf 2, the outside of doorframe 1 is equipped with range hood 3, and the one side of range hood 3 towards doorframe 1 offers external groove 3b, range hood 3
Bottom be connected with turbocharger 4, the smoking pipeline of turbocharger 4 is connected with external groove 3b, the row of turbocharger 4
Smoke 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
The depth of the inner groovy 1a of external groove 3b cooperations, inner groovy 1a are less than external groove 3b, and the width of inner groovy 1a is with outer frame body 3a's
Width is equal, and 1 lateral surface of doorframe is divided into inside casing and outline border by inner groovy 1a, and the width of inside casing is equal with the width of external groove 3b,
Outer frame body 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 1 medial surface of external groove 3b and doorframe, and the internal frame body 3c surfaces of range hood 3 are provided with sealing strip.
When accident, which occurs, for nuclear power station smog leakage occurs, smog can leak at crack between a door and its frame, and the smog of leakage can be from
Smoking gap 6 enters external groove 3b（Smoking passage）, turbocharger siphons away the smog smoked in passage at this time, and is stored in
In air accumulator 5, the smoking gap 6 between 1 medial surface of external groove 3b and doorframe is effectively guaranteed smog when leaking, can
Into smoking passage so that turbocharger 4 can siphon away smog in time；The inner groovy 1a of setting causes outer frame body 3a being inserted into
During inner groovy 1a, the leakproofness that labyrinth seal passage further enhances range hood 3 is formed.
