Abstract
The utility model relates to a fireproof door which has strong fire resistance and can effectively obstruct the spread of a fire. The fireproof door comprises a door frame and a plate-typed door body which is cooperated with the door frame; one side of the door body is hinged to the door frame via hinges, and the door frame and the door body are specially and respectively provided with a cavity; the door frame and the door are respectively provided with an inflow port for door frame cavity and an outflow port for door body cavity, and the tops of the door frame cavity and the door body cavity are respectively provided with a micropore which is communicated with external.
Description
The utility model relates to a kind of door.
Existing panel door is made of doorframe and the panel door body that cooperates with doorframe usually, and a side of door body is articulated on the doorframe by hinge.This panel door has certain theftproof performance.But when breaking out of fire, if flame combustion is near this panel door, then this gate pole easily damages under the baking of flame, thereby allows flame wear door and mistake causes fire spread.
The purpose of this utility model provides a kind of labeled door that stops fire spread.
The panel door body that labeled door of the present utility model has doorframe and matches with doorframe, one side of door body is articulated on the doorframe by hinge, doorframe and door body have cavity especially respectively, on doorframe and door body, be respectively arranged with doorframe cavity inflow port and door body cavity inflow port, be respectively arranged with micropore at doorframe cavity top and door body cavity top with exterior.When near the utility model labeled door during breaking out of fire, can inject a tap water to doorframe and door body by a doorframe and a door body cavity inflow port, make water level in doorframe and the door body cavity reach position near cavity top micropore.In case when flame toasted, makes a doorframe and a door body temperature degree to rise to a doorframe and a door surface, the tap water of splendid attire also heated up in a doorframe and the body cavity thereupon.When the water body in the cavity was warming up to boiling, water promptly was vaporized into steam, and the micropore ejection from cavity top forms steam fog.In the vaporescence of water, doorframe and door body promptly roughly remain on about 100 ℃ because of the water vapor consumption of calorie stops to heat up, and this temperature can not make doorframe and door body damage.In fire, as long as in doorframe and door body, replenish the water yield that consumes because of evaporation by manual or Automatic water valve in good time, can constantly have water body to be vaporized into steam in doorframe and the door body cavity sprays from micropore, thereby make doorframe and the unlikely intensification of door body too high, avoid doorframe and door body in fire, to damage, stop fire spread effectively.When using labeled door of the present utility model, in time in doorframe and door body cavity, inject cooling water during in order to ensure breaking out of fire, can in advance doorframe cavity inflow port and door body cavity inflow port be connected with user's water supply pipe.In addition, pipeline when making this labeled door of user installation connects comparatively easy, also can the doorframe cavity be set and head piece, and allow this go out between head piece and the door body cavity inflow port to be connected with fire-resistant flexible pipe (as refractory fibre pipe or metallic elastic bellows) on doorframe of the present utility model top.Like this, the user only needs the doorframe inflow port is linked to each other with water supply pipe, can use this labeled door.During when breaking out of fire and to the labeled door water filling, current are introduced into the doorframe cavity.When doorframe cavity water level rose to the doorframe cavity and goes out head piece, current can go out head piece from this and overflow, by door body cavity inflow port access door body cavity, opposite house body cavity water-filling.
Compare with aforementioned existing panel door, labeled door of the present utility model has the advantages that anti-firepower is strong, can effectively intercept fire spread.Doorframe and Men Tike are made by steel, aluminium, copper, stainless steel and the materials such as timber after fire-proof flame-retarded agent soaks in this labeled door, have with material characteristics widely.
Content of the present utility model further illustrates with the following Examples, but content of the present utility model is not limited only to content related among the embodiment.
Fig. 1 is the structural representation of labeled door among the embodiment.
As shown in Figure 1, the steel panel door body 2 that the labeled door among the embodiment has steel door frame 1 and matches with doorframe, a side of door body 2 is articulated on the doorframe 1 by hinge 3.Doorframe and door body have cavity 4,5 respectively.Doorframe is provided with cavity inflow port 6 and goes out head piece 7, and the door body is provided with cavity inflow port 8.The doorframe cavity goes out head piece 7 and is arranged at doorframe top, and this goes out head piece 7 and is connected with door body cavity inflow port 8 by metallic elastic bellows 9.Herein, the doorframe cavity goes out near the hinged hinge 3 that head piece 7 and a door body cavity inflow port 8 all be arranged on doorframe and a body.Be respectively arranged with micropore 10,11 with exterior at the top of doorframe cavity 4 and door body cavity 5.When using the labeled door of present embodiment, the tap water pipe line of doorframe inflow port 6 with the user can be joined, and relative set automatic or manual water supply control valve door.In case breaking out of fire, after water valve unlatching artificial or control automatically, current promptly enter doorframe cavity 4 by inflow port 6.Treat that the water level in the doorframe cavity rises to out head piece 7 places, the current that continue to enter overflow from going out head piece 7, through bellows 9 access door body cavitys 5, and opposite house body cavity water-filling, water level reaches near micropore 11 places in door body cavity.At this moment, water valve can cut out, labeled door promptly is in the water-cooled state.If flame is to doorframe and door body baking, when making in doorframe and the door body cavity water boiling, water promptly begins to be vaporized into steam, and top micropore 10, the 11 ejection formation aerosols from doorframe cavity and door body cavity stop doorframe and door body to continue to heat up simultaneously, prevent that doorframe and door body from damaging, and causes fire spread.
Claims (3)
1, a kind of aerosol labeled door, the panel door body that has doorframe and match with doorframe, one side of door body is articulated on the doorframe by hinge, it is characterized in that doorframe and door body have cavity respectively, on doorframe and door body, be respectively arranged with doorframe cavity inflow port and door body cavity inflow port, be respectively arranged with micropore at doorframe cavity top and door body cavity top with exterior.
2, labeled door as claimed in claim 1 is characterized in that being provided with the doorframe cavity on doorframe top goes out head piece, and this doorframe cavity goes out between head piece and the door body cavity inflow port and is connected by fire-resistant flexible pipe.
