Abstract
The utility model relates to a high-air-tight plate type smoke-exhausting gate, which is composed of a valve buckle, blade plates, sealing strips, steel cables, an executive mechanism, and electric lines. The utility model is characterized in that the edge of the circumference of the blade plates is provided with pressing plates and embedded with silicon rubber sealing strips; cross-sections of the sealing strips are in an omega shape; one end of the pressing plates is folded into a groove shape used for holding one side of the sealing stripes; the other end of the pressing plates is in a hemming shape and holds the other side of the sealing strips with the edge of the blade plates. Compared with other plate type flue gas exhausts, the utility model has the advantages that when the valves are closed, the utility model has high gasproof performance and soundproof function. The utility model is suitable for being installed on the plate type flue gas exhausts of the fume exhaust systems of various buildings.
Description
The utility model belongs to the firebreak device that building uses, and particularly relates to a kind of board-like smoke evacuation air-supply arrangement with height air-tightness.
In some important buildings, generally be provided with automatic fire alarm system, need be in the room or the ceiling in corridor etc. locate to be provided with board-like exhaust opening, and controlled by the automatic fire alarm center.Existing board-like exhaust opening, as form by valve buckle, impeller, steel cable, executing agency and electric wiring.When fire took place, control centre sent the signal of telecommunication by fire, by executing agency, steel cable, made the impeller opened smoke-discharging, with support personnel's life security.Existing board-like exhaust opening, sealing strip is arranged on the inboard of valve buckle, because impeller is opened, when closing running clearance need be arranged, therefore at the inboard place of the valve buckle at impeller turning cylinder two ends, sealing strip can not be set, when board-like exhaust opening was normally closed, the inleakage between impeller and the valve buckle was bigger, influences smoke discharging effect.
The purpose of this utility model is, designs and produces a kind of novel board-like exhaust opening, and sealing strip is arranged on the impeller edge, when exhaust opening is normally closed, has high air-tightness, to improve use value.
The airtight board-like exhaust opening of height of the present utility model, form by valve buckle, impeller, sealing strip, steel cable, executing agency and electric wiring, it is characterized in that, pressing plate build-in silastic sealing strip is set in the impeller edge, the sealing strip section is Ω shape, and pressing plate one end is converted into flute profile, a limit of clamping sealing strip, the other end of pressing plate is flanging shape, with the another side of impeller edge clamping sealing strip.
The course of work of the airtight board-like exhaust opening of height of the present utility model is, board-like exhaust opening is normally closed at ordinary times, and the silastic sealing strip at impeller edge produces strain, blocks the running clearance between whole impeller and the valve buckle, reaches high-air-tightness.When fire took place, fire control centre sent the signal of telecommunication, and DC electromagnet and magnetic core adhesive affect the lever hook to throw off, and rope sheave rotates under the effect of unlatching torsionspring, discharges steel cable, and impeller is opened simultaneously, and the exhaust opening start signal is exported in smoke evacuation.When employing is manual, press hand push button, affect the lever hook to throw off, rope sheave rotates under the effect of unlatching torsionspring, discharges steel cable, while impeller opened smoke-discharging, output exhaust opening start signal.Behind the fire, impeller is closed in hand-reset, and the sealing strip at impeller edge is compressive state, pushes against the valve buckle inboard and reaches high-air-tightness.
The utility model has the advantages that: during valve closing, high air-tightness is arranged, and deadening is arranged, be better than the board-like exhaust opening of other pattern.Be applicable to the board-like exhaust opening that is arranged on all kinds of building smoke evacuation systems.
Below in conjunction with drawings and Examples, the utility model will be further described:
Fig. 1 is the organigram of high airtight board-like exhaust opening
Fig. 2 is the A-A profile of Fig. 1
Fig. 3 is the B-B profile of Fig. 1
Fig. 4 is the working state schematic representation of the sealing strip of high airtight board-like exhaust opening
Fig. 5 is the section structure schematic diagram of the sealing strip of high airtight board-like exhaust opening
Fig. 6 is the organigram of the executing agency of high airtight board-like exhaust opening
As seen from the figure, the airtight board-like exhaust opening of height of the present utility model, by valve buckle, impeller, sealing strip, steel cable, executing agency and electric wiring are formed, support 1 is fixed on the valve buckle 2, support 3 is fixed on the impeller 4, be connected with turning cylinder 5 between support 1 and the support 3, be with on the turning cylinder and open torsionspring 6, opening torsionspring one end is fixed on the valve buckle support, the other end is fixed on the impeller support, is fixed with on the valve buckle to open vibration damping limiting block 7 and close positive stop 8, and pressing plate 10 build-in silastic sealing strips 9 are set in the impeller edge, the sealing strip section is Ω shape, pressing plate one end is converted into flute profile, a limit of clamping sealing strip, and the other end of pressing plate is flanging shape, be fixed on the impeller, with the another side of impeller edge clamping sealing strip.One end of steel cable 11 is fixed on the top of impeller, and the other end is fixed on the rope sheave 13 in the executing agency 12, and the guide rope device 14 of steel cable is arranged on the valve buckle, be provided with DC electromagnet 15 in the executing agency, manually opened button 16, microswitch 17, lever hook 18, hand-reset button 19.
