Description

Technical Field

[0001] The invention relates to the technical field of smoke exhaust fire dampers, in particular to a smoke exhaust fire damper with high sealing performance. Background Art

[0002] The smoke exhaust fire damper is a fire protection component installed on the smoke exhaust system pipe. It is usually open at normal times. When the gas temperature in the pipe reaches 280°C, it will automatically close to prevent smoke and fire. The main function of the smoke exhaust fire damper is to automatically close through the temperature sensing mechanism when a fire occurs to prevent the fire from spreading through the smoke exhaust pipe. It is usually made of carbon steel, galvanized sheet or stainless steel and has a certain fire resistance integrity and smoke isolation ability. In addition, the smoke exhaust fire damper needs to undergo various tests to test its performance before leaving the factory to ensure that it can be closed normally during a fire, and the manual operation should be convenient, flexible and reliable.

[0003] Conventional smoke exhaust fire dampers use metal partitions to achieve closed separation of the internal space. On the one hand, the metal partitions may be damaged by moisture corrosion, and on the other hand, the sealing of the structure is relatively limited, and structural leakage may occur.

[0004] Therefore, in view of this, the existing structure and defects are studied and improved, and a high-sealing smoke exhaust fire damper is proposed. Summary of the invention

[0005] The object of the present invention is to provide a smoke exhaust fire damper with high sealing performance to solve the problems raised in the above-mentioned background technology.

[0007] Furthermore, the first seal and the second seal are symmetrically installed at the front and rear ends in the middle of the main valve body, and the second through groove passes through the middle end of the second seal on the lower side of the main valve body, and the flange structure and the main valve body are arranged as an integral structure.

[0008] Furthermore, the winding assembly includes an upper electric winding roller, a support pile, a fixed frame and a remote controller. Support piles are vertically installed at the bottom of the left and right ends of the upper electric winding roller, and the bottom of the support piles is connected to the fixed frame. One end of the upper electric winding roller is connected to the remote controller.

[0009] Furthermore, the fixing frame is welded to the side of the main valve body, and the upper electric winding roller is horizontally arranged above the first through groove.

[0010] Furthermore, the fireproof component includes a closed soft board, a flame retardant coating, a reinforcement sheet, a connecting seal block and a pull ring. The outer surface of the closed soft board is sprayed with a flame retardant coating, and the surfaces of the front and rear sides of the closed soft board are arranged and covered with reinforcement sheets. A connecting seal block is installed in the middle of the bottom end of the closed soft board, and a pull ring is connected to the bottom of the connecting seal block.

[0011] Furthermore, the closed soft plate and the reinforcement plate are both made of flexible fireproof materials, the inner surface structure of the first through groove matches the outer surface structure of the fireproof component, the outer surface structure of the connecting sealing block matches the inner surface structure of the second through groove, and the first seal and the second seal are tightly fitted to the side surface of the fireproof component.

[0012] Furthermore, the traction assembly includes a lower electric winding roller, a fixed pile, a traction rope and a traction ring, the tops of both ends of the lower electric winding roller are vertically connected to the fixed piles, and the middle surface of the lower electric winding roller is wound with a traction rope, and the end of the traction rope away from the lower electric winding roller is connected to the traction ring.

[0013] Furthermore, the traction rope is made of metal material, and the traction ring and the pull ring are sleeved with each other.

[0014] The present invention provides a highly sealed smoke exhaust fire damper, which has the following beneficial effects:

[0015] 1. The present invention provides an upper sealing block on the top of the outer part of the main valve body, and at the same time, cooperates with the first sealing strip and the second sealing strip on the inner surface of the main valve body, so that when the fireproof component with the connecting sealing block installed at the bottom is vertically spread and the interior of the valve body component, as the connecting sealing block is vertically embedded in the second through groove at the bottom of the main valve body, at the same time, both sides of the entire fireproof component will be tightly fitted with the upper sealing block, the first sealing strip and the second sealing strip on the surface, thereby forming a good structural seal, thereby forming an effective structural seal for the front and rear ends of the interior of the valve body assembly. In addition, by providing sealing rings inside the flange structures on the front and rear sides of the main valve body, the pipeline and the valve body assembly themselves have sufficient structural seal after being connected and combined, and leakage is minimized as much as possible, thereby ensuring the structural seal of the device to the greatest extent. The closed soft board with a reinforcing sheet on the surface is made of flexible fireproof material, which not only ensures the structural strength but also facilitates the structural storage. At the same time, combined with the flame retardant coating sprayed on the surface, the smoke exhaust and fire prevention effects can be ensured to the greatest extent.

[0016] 2. The present invention installs a winding assembly and a traction assembly on the upper and lower sides of the valve body assembly respectively, wherein the upper end of the winding assembly is connected to the surface of the upper electric winding roller, and the bottom end of the fire protection assembly is connected to the traction ring at one end of the traction rope through the pull ring at the bottom of the connecting sealing block. By utilizing the cooperative operation of the winding assembly and the traction assembly, when the fire protection assembly needs to be vertically spread and inserted into the winding assembly, the traction rope is wound up by rotating the upper electric winding roller, so that the entire winding assembly enters the interior of the valve body assembly from top to bottom from the first through groove until the connecting sealing block enters the interior of the second through groove. The structure inside the valve body assembly forms a closed structure, and at this time, the appropriate rotation of the upper electric winding roller and the winding of the lower electric winding roller can tighten the winding assembly. When storing the winding assembly, as the upper electric winding roller reels the winding assembly, the lower electric winding roller properly unwinds the traction rope to complete the operation of storing the winding assembly. In addition, the use of the remote controller can be used in conjunction with an external controller connected to it, which can avoid the inconvenience of manual operation and the inability to timely unfold the winding assembly, resulting in the inability to timely block the smoke, thereby improving the operating convenience and flexibility of the device.

[0025] like Figures 1 to 5As shown, the winding assembly 2 includes an upper electric winding roller 201, a supporting pile 202, a fixing frame 203 and a remote controller 204. The supporting piles 202 are vertically installed at the bottom of the left and right ends of the upper electric winding roller 201, and the bottom of the supporting pile 202 is connected to the fixing frame 203.
