Particularly, for the integrity of flange-interface 600 with panel 100, flange-interface 600 also can outwards be stretched by panel 100 and form.
Particularly, four jiaos of panel 100 are provided with mounting hole 130, its valve can be fixedly installed on the exhaust duct by mounting hole 130.
Preferably, in the present embodiment, panel 100, guide pipe 200, fire prevention cover plate 300 all adopts metallic material to make, and guide pipe 200 is fixed on the metal surface 100 by fastening piece or is welded on the metal surface 100.
Preferably, in the present embodiment, fus 400 is selected fuse link for use, and the fuse link cost is low.
In the embodiment of the invention, guide pipe 200 is to contain panel 100 suction ports 110 by a notch plate and panel 100 to surround and form, its cross section is rectangular, and the cross section also can be circle or other shape certainly, and guide pipe also can be formed by connecting by the suction port 110 of a bend pipe lower end and panel 100.
In the embodiment of the invention, fire prevention cover plate 300 is flat type, and the cover plate 300 of preventing fires certainly also can have other forms such as recessed formula, convex surface.
In the embodiment of the invention, 500 of gravity drop hammers have embodied a kind of geometrical shape, can certainly adopt other geometrical shape.
Second embodiment
With reference to Fig. 3, Fig. 4, be the schematic representation of embodiment of the invention fire prevention exhaust structure, present embodiment and first embodiment's difference is, gravity drop hammer 500 changes and is made as elastic force and hammers 510 into shape.
Particularly, elastic force hammer 510 is made for metal spring, and elastic force hammer 510 is fixed on the panel 100 by fixed block 520, certainly, also can be fixed on the cover plate 300 of preventing fires.Need to prove that elastic force hammer 510 is made by at least one metal spring, also can be made by at least one metal clips.
Particularly, symmetrical openings 220 on guide pipe 200 both sides, fire prevention cover plate 300 bottoms are provided with first rotating shaft (not marking among the figure), are articulated in the symmetrical openings 220 of guide pipe 200 two sides by first rotating shaft.
Further, the outside of panel 100 is provided with the safety check 700 that is communicated with suction port 110, and safety check 700 is last inclined to one side gas-discharging type safety check in the present embodiment.State when wherein, dotted line represents that the non-return sheet of safety check 700 is opened among Fig. 4.Certainly, also can select down inclined to one side gas-discharging type safety check for use.Present embodiment and first embodiment's something in common do not repeat them here.
Certainly, for strengthening plugging effect, gravity drop hammer 500 and elastic force hammer 510 can be set simultaneously also herein.
The 3rd embodiment
With reference to Fig. 5, Fig. 6, be the schematic representation of embodiment of the invention fire prevention exhaust structure.Present embodiment and first embodiment's difference is, guide pipe 200 outlet end are established a normally closed non-return sheet 800, when induced draft fan in the pipeline during exhaust, normally closed non-return sheet 800 is opened, when stopping in the pipeline exhaust, normally closed non-return sheet 800 deadweights fall after rise closes, and the passage of capping guide pipe 200 prevents that the gas in the pipeline from pouring in down a chimney out.Among Fig. 6, dotted line is represented state under the unlatching of normally closed non-return sheet 800.
Particularly, guide pipe 200 two side symmetries offer circular hole 230, and two ends are established the second rotating shaft (not shown) and are articulated in circular hole 230 on the normally closed non-return sheet 800.
In the present embodiment, normally closed non-return sheet 800 is made for metal.Certainly, normally closed non-return sheet 800 also can be plastics and makes.
Particularly, establish a convex-concave band 240 in guide pipe 200 perisporiums, normally closed non-return sheet 800 and convex-concave band 240 superimposed sealing guide pipe 200 passages reach the purpose that prevents that effectively gas pours in down a chimney out in the pipeline.Other is identical with first embodiment, does not give unnecessary details herein.
The 4th embodiment
With reference to Fig. 7, Fig. 8, be the schematic representation of embodiment of the invention fire prevention exhaust structure.Present embodiment and the 3rd embodiment's difference is, guide pipe 200 outer periphery one Venturi effect plate 900, here the Venturi effect plate 900 of She Zhiing, its objective is that Venturi effect plate 900 and guide pipe 200 are surrounded forms the transformation space, like this, when upward flow passes through in the pipeline, this space produces transformer action, play the positive pressure that reduces this place's suction port 110, even reach negative pressure state, play a kind of fixed structure form and prevent that gas pours in down a chimney measure in the pipeline.Simultaneously, by transformer action, induced draft fan blast pressure value and suction port 110 place's force value value differences are increased, thereby increase the air displacement in the pipeline, simultaneously, the induced draft fan exhaust enters the transformation space, form the rising jet qigong effect is pulled out in the generation of pipeline lower floor, make system exhaust unimpeded.In the present embodiment, Venturi effect plate 900 adopts metallic material to make, and it is by fastening piece or be fixedly welded on the panel 100, and Venturi effect plate 900 also can adopt plastics or other material to make certainly.Repeat no more with the 3rd embodiment's something in common.
The 5th embodiment
With reference to Fig. 9, the generalized section of the fire prevention exhaust structure that provides for the embodiment of the invention.Present embodiment and the 3rd embodiment's difference is, panel 100 is provided with opening 140, being provided with in the guide pipe 200 can be from opening 140 extractions and the normally closed check device 810 that inserts, normally closed check device 810 can be extracted cleaning, the replacing of convenient normally closed check device 810 out from the opening 140 of panel 100.Dotted line is represented the following state of non-return sheet unlatching of normally closed check device 810 among Fig. 9.Certainly, normally closed check device 810 can be made by plastics or metal.Its function is not given unnecessary details with the 3rd embodiment herein.
Need to prove, more than among each embodiment, fire prevention cover plate 300 is all greater than guide pipe 200 outlets 210, certainly, fire prevention cover plate 300 can not given unnecessary details the concrete grammar of shutoff guide pipe 200 passages under this type of situation at this less than guide pipe 200 outlets 210 yet.
Below only be 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., all should be included within protection scope of the present invention.
