Description
Technical field
The utility model relates to a kind of fire resisting damper, particularly relates to the high fire-resistant fire resisting damper of high-air-tightness in a kind of fire-fighting system being applied in the ventilation shafts such as building, basement and tunnel.
Background technology
Applied fire resisting damper in current fire-fighting ventilating system, while running into fire, in set point of temperature and in the time, general equal can realization closed automatically, play isolated burning things which may cause a fire disaster, the effect of blocking-up flue gas, but existing common fire resisting damper only depends on valve block and valve block, sealing between valve block and valve body, sealing property is generally not good, and along with fire time duration, temperature constantly raises, make blade produce distortion, there is larger gap, leaking cigarette amount increases, the effective time of fire resisting damper is shorter, high-temperature flue gas sharply spreads along pipeline by the gap of fire resisting damper, can cause very large disaster.
Utility model content
For overcoming above-mentioned defect; the utility model aims to provide the fire-resistant fire resisting damper of a kind of high airtight height; this fire resisting damper allows in very long high-temperature duration; by using simple mechanism and not expensive expense; stop flame to spread in air channel, guarantee between the local place of need protection and outside, effectively to separate.
For achieving the above object, the utility model solves the technical scheme that its technical problem adopts: the fire-resistant fire resisting damper of a kind of high airtight height, comprise two vertical frame plates and the two rectangle valve bodies that crossing frame plate surrounds by positioned opposite, several valve blocks, a meltable bar and an execution machine, described valve block is rotationally connected by sharf and two crossing frame plates, the inner side of described vertical frame plate is respectively equipped with a baffle plate, the inner side of described two crossing frame plates is respectively equipped with blade rack and spring case, described valve block comprises a blade, described blade is provided with three road reinforcements, the reinforcement of described centre is connected with sharf, the reinforcement protrusion direction on described two limits is contrary, in the opposite direction of the reinforcement projection on described two limits, be respectively provided with a reinforced sheet, the contact position of described adjacent two blades is provided with sealing reed, described sealing reed protrudes from the end of blade.
Between described two vertical frame plates, be also provided with one or more center frame plate, the middle-end of described sharf is passed center frame plate and is rotationally connected with center frame plate, on two end faces up and down of described center frame plate, is respectively equipped with blade rack and spring case.
Adopt the fire-resistant fire resisting damper of the airtight height of height of the present utility model, by adding spring case and sealing reed, make between valve block and valve body, between valve block and valve block, there is better sealing, meanwhile, by add reinforcement and reinforced sheet on valve block, can make valve block indeformable under the hot environment that stands the long period, increase the effective time of fire resisting damper, given the longer escape time of evacuation personnel.

Detailed description of the invention
As shown in Figure 1-Figure 3, the utility model discloses the fire-resistant fire resisting damper of a kind of high airtight height, comprise two vertical frame plates 5 and the two rectangle valve bodies 1 that crossing frame plate 15 surrounds by positioned opposite, several valve blocks 2, a meltable bar 3 and an executing agency 4, described valve block 2 is rotationally connected by sharf 12 and two crossing frame plates 15, when normality, fire resisting damper is all opened, when fire, in the time arriving design temperature, control centre is to 4 one executive signals of execution machine, execution machine 4 operates valve block 2 and cuts out, fire resisting damper is blocked ventilation shaft, prevent that flue gas from entering, if breaking down, execution machine 4 cannot normally close valve block 2, in the time reaching a higher design temperature, meltable bar 3 fuses, under the effect of spring force, valve block 2 is closed automatically. in sum, basically identical with existing common fire-proof valve structure.
The innovative point of the fire-resistant fire resisting damper of the airtight height of height of the present utility model is mainly that described valve block 2 comprises a blade 9, described blade 9 is provided with three road reinforcements, the reinforcement of described centre is connected with sharf 12, the reinforcement protrusion direction on described two limits is contrary, in the opposite direction of the reinforcement projection on described two limits, be respectively provided with a reinforced sheet 10, by compacting reinforcement, can improve the rigidity of blade 9, make blade 9 be not easy to distortion, simultaneously, by adding reinforced sheet 10, the protrusion direction of common described reinforced sheet 10 is contrary with the protrusion direction of reinforcement, make reinforced sheet 10 positions there is a circular structure, there is high rigidity, can prevent that blade 9 is indeformable under the hot environment of certain hour,
The contact position of described adjacent two blades 9 is provided with sealing reed 11, described sealing reed 11 protrudes from the end of blade 9, in the time that valve block 2 is closed, adjacent two blades 9 partially overlap, sealing reed 11 is positioned at blade 9 overlapping positions just, clamped by two blades 9, further increased the air-tightness of 9, blade, prevent from leaking out;
The inner side of described vertical frame plate 5 is respectively equipped with a baffle plate 6, and in the time of practical operation, described plate washer 6 is converted into by " L " shape steel plate, and in the time that valve block 2 is closed, valve block 2 ends and baffle plate 6 partially overlap, and prevent from leaking out;
The inner side of described two crossing frame plates 15 is respectively equipped with blade rack 7 and spring case 8, blade rack 7 is mainly used to connect sharf 12, when described spring case 8 normality, it is protruding state, when valve block 2 is closed, spring case 12 is subject to blade extruding, projection flattens, and forms sealing with blade, prevents from leaking out.
For the fire resisting damper of large-size, in order to ensure rigidity and the intensity of its valve block 2, another innovative point of the fire-resistant fire resisting damper of the airtight height of height described in Ben Biming is to be also provided with one or more center frame plate 25 between described two vertical frame plates 5, the middle-end of described sharf 12 is passed center frame plate 25 and is rotationally connected with center frame plate 25, on two end faces up and down of described center frame plate 25, is respectively equipped with blade rack 7 and spring case 8.
