Water conservancy diversion exhaust fire-closing valve provided by the invention, comprise the panel that is provided with suction port, be provided with when fire between the fire prevention cover plate of being located at described panel one side and the guide pipe that is communicated with suction port and being articulated in the outlet of described guide pipe, described fire prevention cover plate and described panel described fire prevention cover plate is put down the described guide pipe outlet of shutoff and recovers under normal conditions the relative described guide pipe of described fire prevention cover plate is exported the fixing-assembly of opening and fixing.In the present invention, the fixing-assembly cover plate of preventing fires puts down the outlet of the described guide pipe of shutoff when fire, and recover under normal conditions the relatively described guide pipe outlet of described fire prevention cover plate is opened and fixed, water conservancy diversion exhaust fire-closing valve is reusable like this, having overcome the fusing of existing fus or fuse link disconnects the cover plate of prevent fires and falls the disposable fire prevention of capping guide pipe outlet and move, reduce replacement cost, use more convenient, quick.
In the present invention, the structure of fixing-assembly can have multiple, describes in detail below in conjunction with accompanying drawing.
The first embodiment
With reference to Fig. 1, Fig. 2, be the schematic diagram of water conservancy diversion exhaust fire-proof valve structure in first embodiment of the invention.Described water conservancy diversion exhaust fire-closing valve is located at the suction port place of common exhaust duct for dwelling.Described water conservancy diversion exhaust fire-closing valve comprises the panel 100 that is provided with suction port 110, but is located at the inboard and guide pipe 200 that is communicated with suction port 110 of panel 100 and is located on guide pipe 200 and capping guide pipe 200 exports 210 fire prevention cover plate 300.Panel 100 is provided with mounting hole 120, by screw being passed mounting hole 120, panel is fixed in air outlet flue.Fire prevention cover plate 300 is articulated on guide pipe 200 by hinging shaft 310, therefore the outlet 210 of its relative guide pipe 200 is opened or sealed.
In the present embodiment, be provided with fixing-assembly 400 between fire prevention cover plate 300 and panel 200.The second link 420 that fixing-assembly 400 is fixed in the first link 410 of panel 100 inboards and is located at fire prevention cover plate 300 outsides.The right-hand member of the first link 410 has the first hook portion 411, the left end of the second link 420 has the second hook portion 421, the first hook portion 411 and the second mutual clasp joint of hook portion 421 in together with, thereby make fire prevention cover plate 300 with respect in guide pipe 200 outlets 210 in opened condition.Certainly, the first link 410 and the second link 420 also can adopt other structure clasp joint in together with.In the present embodiment, the second link 420 that sets firmly on fire prevention cover plate 300 adopts temperature sensitive metal or two-way memory alloy to make.Certainly, the first link 410 that sets firmly on panel 100 also can adopt temperature sensitive metal or two-way memory alloy to make.When fire occured, the second link 420 was heated and moves on moving the second hook portion 421 of upper shipper pole, and the second hook portion 421 is come off with curved the first hook portion 411, and the outlet 210 of fire prevention cover plate 300 whereabouts capping guide pipes 200 reaches the technique effect that intercepts fire spread.In Fig. 2, dotted line represents the working condition signal under fire condition, and under recovery normal temperature, the second link 420 recovers ortho states.At this moment the available fire prevention cover plate 300 that pushes away on hand, make the first hook portion 411 and the second hook portion 421 clasp joints on the second link 420 on the first link 410, the normality that the cover plate 300 that recovers to prevent fires is opened.
Particularly, in the present embodiment, the shape of the first link 410 and the second link 420 can be sheet band shape, circle strip or spring-like.Certainly, also can be designed to according to actual needs other shape.
In the present embodiment, the first link 410 can adopt and be welded and fixed, screw is fixed or rivet is fixed on panel 100, and is same, and the second link 420 also can adopt and be welded and fixed, screw is fixed or rivet is fixed on fire prevention cover plate 300.
The second embodiment
With reference to Fig. 3, Fig. 4, be the schematic diagram of water conservancy diversion exhaust fire-proof valve structure in second embodiment of the invention.The present embodiment and first embodiment's difference are, set up the positioning screw 500 of the clasp joint depth on the second link 420.Certainly, positioning screw 500 also can be located on the first link 410, by the adjusting of positioning screw 500, thereby controls more accurately effective unhook distance, reaches more precision maneuver requirement, and in Fig. 4, dotted line represents the working condition under fire condition.The present embodiment and first embodiment's something in common do not repeat them here.
The 3rd embodiment
With reference to Fig. 5, Fig. 6, be the schematic diagram of water conservancy diversion exhaust fire-proof valve structure in third embodiment of the invention.The present embodiment and first embodiment's difference be, first link 410 right-hand member the first hook portions 411 change rectangular through-hole 412 into, certainly, also can change the second hook portion 421 of the second link 420 left ends 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 first embodiment's something in common also repeat no more at this.
The 4th embodiment
With reference to Fig. 7, Fig. 8, be the schematic diagram of water conservancy diversion exhaust fire-proof valve structure in fourth embodiment of the invention.The present embodiment and first embodiment's difference are, the structure difference of fixing-assembly 400.In the present embodiment, fixing-assembly 400 except comprise the first link 410 of being fixed in panel 100 inboards, be located at fire prevention cover plate 300 outsides and can with the second link 420 of the first link 410 clasp joints, top/the draw piece 430 that also comprises the below that is positioned at the second link 420, top/draw piece 430 adopts temperature sensitive metal or two-way memory alloy to make.Certainly, top/draw piece 430 also can be located at the below of the first link 410, is heated the first link 410 is produced lower pulling force, and the first hook portion 411 and the second hook portion 421 are broken away from; Certainly, top/draw piece 430 also can be located at the top of the first link 410 or the second link 420, draws on being heated or push up down the first hook portion 411 and the second hook portion 421 are broken away from.When the present embodiment fire occured, top/draw piece 430 action of being heated upwards promoted the second link 420, thus the second hook portion 421 and the first hook portion 411 disengagings, and the outlet 210 of the cover plate 300 falling capping guide pipes 200 of preventing fires prevents fire spread.When recovering normal temperature, top/draw piece 430 returns to normal, and at this moment, pushes away the second hook portion 421 on cover plate 300, the second links 420 of preventing fires and the first hook portion 411 clasp joints of the first link 410 on manually.In the present embodiment, top/draw piece 430 is the sheet band shape of bending, and it also can be spring-like or other any shape certainly.Top/draw piece 430 also can be installed on panel 100.Top/draw piece 430 action of being heated, no matter be to back down or pull open, effect is all in order to make the second hook portion 421 and the first hook portion 411 unhook.Certainly, also can be on the first link 410, or the second link 420, or arrange in positioning screw 500(diagram not shown on top/draw piece 430).Top/draw piece 430 also can adopt and be welded and fixed, screw is fixed or rivet is fixed.The present embodiment and first embodiment's something in common also repeat no more at this.
These are only preferred embodiment of the present invention, not in order to limiting the present invention, all any modifications of doing within the spirit and principles in the present invention, be equal to and replace and improvement etc., within all should being included in protection scope of the present invention.
