Description

Technical Field

[0001] This utility model belongs to the field of fire damper technology, and in particular relates to a fire damper that facilitates cleaning of the valve plate. Background Technology

[0002] A fire damper is a type of valve controlled by a shape memory alloy, closing using gravity and a spring mechanism. Newer products also utilize the deformation of the shape memory alloy to close the valve. Its function is as follows: when the smoke temperature reaches 280℃, most people have already evacuated, smoke extraction is no longer practical, and the smoke already contains fire; the valve automatically closes to prevent the fire from spreading. Fire dampers control the rotation of multiple shafts, which in turn rotate valve plates, thus controlling the valve's opening and closing. Over time, dust accumulates on the valve plates, requiring regular cleaning for optimal performance. This cleaning necessitates disassembling the valve plates from the shafts; however, existing valve plates are either directly welded to the shafts or secured with multiple bolts, making disassembly and cleaning inconvenient. Utility Model Content

[0003] The purpose of this utility model is to provide a fireproof valve that facilitates the cleaning of the valve plate. The valve plate is fixed to the rotating shaft by a fixing mechanism, which solves the problem that the existing valve plate is directly welded to the rotating shaft or fixed to the rotating shaft by multiple bolts, making disassembly and cleaning inconvenient.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figure 1-5 This utility model is a fireproof valve that facilitates cleaning of the valve plate. It includes a fireproof valve body 1, and multiple rotating shafts 4 are connected inside the fireproof valve body 1. A valve plate 5 is placed on one side of each of the multiple rotating shafts 4. A fixing mechanism is provided between the valve plate 5 and the rotating shaft 4 on both sides. The valve plate 5 can be fixed on the rotating shaft 4 by the fixing mechanism.

[0026] The fixing mechanism includes a plate 10 and a hole 11. The hole 11 is opened on one side of the valve plate 5. The plate 10 is fixed on one side of the rotating shaft 4. The side wall of the plate 10 passes through the hole 11 and extends outward. Limiting mechanisms 8 are provided on both sides of the plate 10. The plate 10 can be vertically limited by passing through the hole 11, and the limiting mechanism 8 can be horizontally limited, thereby fixing the valve plate 5.

[0027] Among them, such as Figure 1-3 As shown, both sides of the fire damper body 1 are fixed with annular plates 2, and each of the four corners of the two annular plates 2 is provided with mounting holes 3. By using bolts to pass through the mounting holes 3 and then fixing them to the wall, the fire damper body 1 can be fixed to the wall.

[0028] Among them, such as Figure 1-3 As shown, side plates 6 are fixed on both sides of the valve plate 5, and the two side plates 6 are placed on both sides of the rotating shaft 4 respectively. Rubber pads 7 are fixed on the side walls of the two side plates 6. By placing the two side plates 6 on both sides of the rotating shaft 4, the valve plate 5 can be placed on one side of the rotating shaft 4 more stably.
