Embodiment

The utility model is described in further detail with specific embodiment below in conjunction with the accompanying drawings.

In the accompanying drawings, a kind of airproof fire valve, is specifically included：Valve body framework (valve body framework top frame 1 and valve body framework Body side frame 4) its surrounding fixed by corner brace 6, executing agency 2, extension spring 16, blade assembly, wherein, blade assembly two ends are set respectively First baffle 21 and second baffle 18 are equipped with, executing agency 2 is fixed on the valve body framework 1, and axle is provided with valve body framework 1 Support 5 and link assembly, and one end of link assembly is fixed with case 17, the one end of extension spring 15 is by nut 19 and valve body framework It is fixedly connected, one end connection of the other end and link assembly；Multiple sealing devices are additionally provided with blade assembly.

Wherein, blade assembly include multiple blades 10 and multiple sharfs 11, multiple blades 10 by multiple sharfs 11 according to Minor tick is connected；Link assembly includes connecting rod 13 and multiple connecting rod racks 12, and connecting rod 13 is fixed on the multiple connecting rod rack 12 On；And multiple connecting rod racks 12 are fixed up by many rivets 14, and one end of link assembly is fixed with case 17, and even Copper sheathing 7 is provided between bar 13 and second baffle 18；Sealing device is the combination of sealing reed 8 and reed briquetting 9, seals reed 8 are arranged between blade 10 and reed briquetting 9, and the shape of reed briquetting 9 can be square or circular for rectangle.

Especially, when not installing cone block heat detector 3 in the executing agency of the fire valve, then the fire valve is discharged fume to be a kind of Valve；When in the executing agency of the fire valve install cone block heat detector 3 when, wherein, if the cone block heat detector 3 when reaching 70 DEG C just Start fusing, be then fire resisting damper, if the cone block heat detector 3 just starts fusing when reaching 280 DEG C, for smoke exhaust fire damper, be Label 20 can be set on fire-fighting valve body framework by distinguishing this several fire valve.The principle to these three fire valves does letter below Illustrate.

Especially, fire valve can be selected according to the condition of a disaster situation, if only smog, then using exhaust smoke valve, specifically, works as row When the executing agency 2 of cigarette valve senses smoke signal, then the actuating mechanism of exhaust smoke valve 2 releases drag-line by its draw-gear, Bracing strut 5 therein is rotated, so that connecting rod 13 starts transmission the blade in fire resisting damper is closed, is prevented smog through ventilation shaft Channel to other regions of building.

When there is the condition of a fire, when the cone block heat detector 3 in fire resisting damper reaches 70 DEG C, cone block heat detector 3 starts fusing, performs Mechanism 2 releases drag-line by its draw-gear, and bracing strut 5 therein is rotated, and causes so that connecting rod 13 starts transmission in fire resisting damper Blade close, prevent flare from channeling to other regions of building through ventilation shaft.

When the intensity of a fire is very big, the cone deblocking temperature device in anti-fire smoke expelling valve is when temperature reaches 280 DEG C, and cone block heat detector 3 is opened Begin to fuse, drag-line is released by its draw-gear in executing agency 2, bracing strut 5 therein is rotated, so that connecting rod 13 starts transmission So that the blade in fire resisting damper is closed, prevent big fire from channeling to other regions of building through ventilation shaft.

Due to being mounted with sealing device between above-mentioned fire valve blade assembly so that the sealing property of the fire valve is more preferable, So as to reduce inleakage well.

Above-described embodiment is only intended to clearly illustrate the description that the utility model is made, and the not limit to embodiment It is fixed, to those of ordinary skill in the art, other various forms of changes can also be made on the basis of the above description Or change, there is no necessity and possibility to exhaust all the enbodiments, and the obvious change thus amplified out Or among changing still in protection domain of the present utility model.
