In order to make object of the present invention, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the present invention is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the present invention, be not intended to limit the present invention.
Stream guidance air discharge fire damper provided by the invention, comprise the panel being provided with air inlet, be located at described panel side and the guide pipe be communicated with air inlet and be articulated with the fireproof cover plate that described guide pipe exports, be provided with between described fireproof cover plate with described panel and described fireproof cover plate put down guide pipe described in shutoff when fire and export and recover relative for described fireproof cover plate described guide pipe to export under normal conditions to open and the fixation kit fixed.In the present invention, when fire, fireproof cover plate is put down guide pipe outlet described in shutoff by fixation kit, and recover relatively described for described fireproof cover plate guide pipe outlet open and fix under normal conditions, such stream guidance air discharge fire damper is reusable, overcome existing fuse or fuse link fusing to disconnect and fireproof cover plate is fallen capping guide pipe export disposable fire prevention action, reduce replacement cost, use more convenient, quick.
In the present invention, the structure of fixation kit can have multiple, describes in detail below in conjunction with accompanying drawing.
First embodiment
With reference to Fig. 1, Fig. 2, it is the schematic diagram of stream guidance air discharge fire damper structure in first embodiment of the invention.Described stream guidance air discharge fire damper is located at the air inlet place of common exhaust duct for dwelling.Described stream guidance air discharge fire damper comprises the panel 100 being provided with air inlet 110, be located at the guide pipe 200 that is communicated with inside panel 100 and with air inlet 110 and to be located on guide pipe 200 and can capping guide pipe 200 export 210 fireproof cover plate 300.Panel 100 is provided with installing hole 120, by being fixed in exhaust duct by panel through installing hole 120 by screw.Fireproof cover plate 300 is articulated with on guide pipe 200 by jointed shaft 310, therefore the outlet 210 of its relative guide pipe 200 is opened or close.
In the present embodiment, between fireproof cover plate 300 and panel 200, be provided with fixation kit 400.The second connector 420 that fixation kit 400 is fixed on the first connector 410 inside panel 100 and is located at outside fireproof cover plate 300.The right-hand member of the first connector 410 has the first hook portion 411, the left end of the second connector 420 has the second hook portion 421, first hook portion 411 and the second hook portion 421 mutually hook are connected together, thus during fireproof cover plate 300 is exported relative to guide pipe 200 210 in opened condition.Certainly, the first connector 410 and the second connector 420 also can adopt other structure hook to be connected together.In the present embodiment, the second connector 420 that fireproof cover plate 300 sets firmly adopts thermometal or two-way memory alloy to make.Certainly, the first connector 410 panel 100 set firmly also can adopt thermometal or two-way memory alloy to make.When fire occurs, the second connector 420 is heated in dynamic second hook portion 421 of upper shipper pole and moves, and the second hook portion 421 is come off with curved first hook portion 411, and fireproof cover plate 300 falls the outlet 210 of capping guide pipe 200, reaches the technique effect intercepting fire spread.In Fig. 2, dotted line represents the working condition signal under fire condition, and when under recovery normal temperature, the second connector 420 recovers ortho states.At this moment with pushing away fireproof cover plate 300 on hand, the first hook portion 411 on the first connector 410 and the second hook portion 421 clasp joint on the second connector 420 can be made, recovering the normality that fireproof cover plate 300 is opened.
Particularly, in the present embodiment, the shape of the first connector 410 and the second connector 420 can be sheet band shape, circle strip or spring-like.Certainly, also other shape can be designed to according to actual needs.
In the present embodiment, the first connector 410 can adopt be welded and fixed, screw fixes or rivet is fixed on panel 100, same, the second connector 420 also can adopt be welded and fixed, screw fixes or rivet is fixed in fireproof cover plate 300.
Second embodiment
With reference to Fig. 3, Fig. 4, it is the schematic diagram of stream guidance air discharge fire damper structure in second embodiment of the invention.The present embodiment and the first embodiment difference are, the second connector 420 is set up the positioning screw 500 of the clasp joint depth.Certainly, positioning screw 500 also can be located on the first connector 410, by the adjustment of screw 500 of transposing, thus controls the distance that effectively breaks off relations more accurately, reaches more precision maneuver requirement, and in Fig. 4, dotted line represents the working condition under fire condition.The present embodiment and the first embodiment something in common do not repeat them here.
3rd embodiment
With reference to Fig. 5, Fig. 6, it is the schematic diagram of stream guidance air discharge fire damper structure in third embodiment of the invention.The present embodiment and the first embodiment difference are, the first connector 410 right-hand member first hook portion 411 changes rectangular through-hole 412 into, certainly, also can change the second hook portion 421 of the second connector 420 left end into rectangular through-hole, and hook hinge form can be a variety of in a word.In Fig. 6, dotted line represents the working condition under fire condition.The present embodiment and the first embodiment something in common also repeat no more at this.
4th embodiment
With reference to Fig. 7, Fig. 8, it is the schematic diagram of stream guidance air discharge fire damper structure in fourth embodiment of the invention.The present embodiment and the first embodiment difference are, the structure of fixation kit 400 is different.In the present embodiment, fixation kit 400 is fixed on the first connector 410 inside panel 100 except comprising, to be located at outside fireproof cover plate 300 and can with the second connector 420 of the first connector 410 clasp joint, also comprise the top/draw piece 430 of the below being positioned at the second connector 420, top/draw piece 430 adopts thermometal or two-way memory alloy to make.Certainly, top/draw piece 430 also can be located at the below of the first connector 410, is heated to produce lower pulling force to the first connector 410, and the first hook portion 411 and the second hook portion 421 are departed from; Certainly, top/draw piece 430 also can be located at the top of the first connector 410 or the second connector 420, and pull-up of being heated or lower top make the first hook portion 411 and the second hook portion 421 depart from.When the present embodiment fire occurs, top/draw piece 430 is heated action, upwardly the second connector 420, thus the second hook portion 421 and the first hook portion 411 depart from, and fireproof cover plate 300 falls the outlet 210 of capping guide pipe 200 after rise, prevents fire spread.When recovering normal temperature, top/draw piece 430 returns to normal, and at this moment, pushes away fireproof cover plate 300 manually, the second hook portion 421 on the second connector 420 and the first hook portion 411 clasp joint of the first connector 410.In the present embodiment, the sheet of top/draw piece 430 in bending is banded, and it also can be spring-like or other any shape certainly.Top/draw piece 430 also can set firmly on panel 100.Top/draw piece 430 is heated action, no matter be back down or pull open, effect is all to make the second hook portion 421 and the first hook portion 411 break off relations.Certainly, also can on the first connector 410, or the second connector 420, or top/draw piece 430 is arranged in positioning screw 500(diagram not shown).Top/draw piece 430 also can adopt be welded and fixed, screw fixes or rivet is fixed.The present embodiment and the first embodiment something in common also repeat no more at this.
These are only preferred embodiment of the present invention, not in order to limit the present invention, all any amendments done within the spirit and principles in the present invention, equivalent replacement and improvement etc., all should be included within protection scope of the present invention.
