Abstract
The utility model relates to an automatic resetting fireproof tuyer, which is characterized in that one end of a tension spring which is used for starting and closing a vane of a thin fireproof valve is fixed to a linkage rod of the vane and the other end is fixed to an outer frame board. A fireproof actuating mechanism is formed by that a thermosensitive spring of shape-memory alloy of 70 DEG C is sheathed on a slide shaft rod, and is fixed between a bracket of the vane and the outer frame board. Compared with a traditional fireproof tuyere, the utility model has the advantages of repeated use of the thermosensitive spring by myriad times without failure and sensitive and reliable actions. An electromagnet, a micro motor, a temperature fuse, etc., in the traditional fireproof tuyere are not required. The automatic resetting fireproof tuyer simplifies design, provides convenience for maintenance, and saves expenses. The utility model is suitable for fireproof tuyeres of various buildings.
Description
The utility model relates to the firebreak device that uses in the building, particularly a kind of fire prevention air port that is used for constructure ventilation air-conditioning system return air duct.
At present, in some important buildings, generally need the fire prevention air port be set in the side and the end of the return air duct of ventilation and air conditioning system.Fire prevention air port 70 ℃ of fusible alloy fuse link mineral wool executing agencies of normal employing.Often open at ordinary times in the fire prevention air port, when breaking out of fire, and the fusing of temperature fusible alloy sheet, the slim fire resisting damper blade of parts in fire prevention air port is closed under the effect of extension spring, with blocking-up flame, prevents that the intensity of a fire from entering return air duct and spreading; But after the fire, when the slim fire resisting damper blade of needs is opened once more, need pull down aluminium alloys branch style grid, change temperature fusible alloy sheet again, and need manually open the fire prevention air port.
The purpose of this utility model is, design applying shape memory alloy temperature sensing spring is as fire prevention executing agency, by fire-protection valve blade linkage, automatically the unlatching of the slim fire-protection valve of control is closed, and unlatching automatically resets, with the raising degree that is active in one's movements, need not to change the fusible alloy sheet, do not need manually to open fire resisting damper and reset, to save the maintaining expense.
The fire prevention air port that automatically resets of the present utility model, form by aluminium alloys branch style grid, slim fire resisting damper, the extension spring that opens and closes slim fire resisting damper blade and fire prevention executing agency, it is characterized in that, be provided with gangbar between the support of blade, one end of the extension spring that blade opens and closes is fixed on the gangbar, and other end support is fixed on the exterior deckle board that is parallel to blade rotor; Fire prevention executing agency is enclosed within on the sliding shaft rod by 70 ℃ of marmem temperature sensing springs and constitutes, end at temperature sensing spring is provided with the adjusting nut that is fixed on the sliding shaft rod, one end of sliding shaft rod is fixed on picking out on the bar of blade rack, and the other end passes the upper end hole that is fixed on the support on the exterior deckle board.
Using method of the present utility model is, during normal temperature, the extension spring power that blade opens and closes is greater than the faint rigidity of 70 ℃ of marmem temperature sensing springs, and the blade that drives slim fire resisting damper is in opening; When fire takes place, 70 ℃ of marmem temperature sensing springs produce the variation of shape and recovery stress along with variation of temperature, and shape and recovery stress variation are to change according to given temperature rule, this moment, temperature sensing spring can overcome extension spring power, and the blade that drives slim fire resisting damper is closed; After the fire, after fire prevention air port air themperature of living in dropped to normal temperature, 70 ℃ of marmem temperature sensing springs recovered faint rigidity, at this moment, extension spring power overcomes the faint rigidity of 70 ℃ of marmem temperature sensing springs again, and the blade that drives slim fire resisting damper resets to opening; Use so repeatedly, 70 ℃ of marmem temperature sensing springs can not lose efficacy yet.
The utility model has the advantages that: compare with the disposable 70 ℃ of fusible alloy fuses in traditional fire prevention air port, because 70 ℃ of marmem temperature sensing springs can use up to ten thousand times repeatedly, can not damage,, need not change the fusible alloy sheet so being active in one's movements of fire prevention executing agency is reliable; At normal temperatures, the blade of slim fire resisting damper is opened voluntarily, when the fire fire took place, valve was closed automatically, after the fire, after air themperature drops to normal temperature, valve automatically resets to the entire work process of opening again, does not need electricity consumption, need not adopt critical element DC electromagnet in the tradition fire prevention air port, micro machine parts, gear reduction unit, retaining mechanism, temperature fuse etc., simplify design, saved user's maintaining expense.Be applicable to the fire prevention air port of various buildings.
Below in conjunction with drawings and Examples, the utility model is further described.
Fig. 1 be automatically reset the fire prevention air port structural representation.
Fig. 2 be automatically reset the fire prevention air port lateral view
Fig. 3 is an extension spring mounting structure schematic diagram.
Fig. 4 is 70 ℃ of marmem temperature sensing spring mounting structure schematic diagrames.
As seen from the figure, the fire prevention air port automatically resets, form by aluminium alloys branch style grid 2, slim fire resisting damper 1, the extension spring 4 that opens and closes slim fire resisting damper blade 6 and fire prevention executing agency 3, it is characterized in that, be provided with gangbar 7 between the support 8 of blade, one end of the extension spring that blade opens and closes is fixed on the gangbar 7, and other end support 9 is fixed on the exterior deckle board 5 that is parallel to blade rotor; Fire prevention executing agency is enclosed within on the sliding shaft rod 13 by 70 ℃ of marmem temperature sensing springs 3 and constitutes, end at temperature sensing spring is provided with the adjusting nut 12 that is fixed on the sliding shaft rod, one end of sliding shaft rod is fixed on picking out on the bar 14 of blade rack 10, and the other end passes the upper end hole of the support 11 that is fixed on the exterior deckle board.
