Description

Technical Field

[0001] This utility model relates to the field of anti-leakage structure technology, specifically, to an anti-gas leakage structure for a gas generator. Background Technology

[0002] Gas generators are core equipment used in industrial sectors such as chemical, metallurgical, and building materials industries to produce gas. Their safe operation is directly related to production continuity and the safety of personnel and the environment. Gases, such as water gas, semi-water gas, and coke oven gas, are flammable, explosive, and toxic. Once a leak occurs, it can easily lead to explosions, poisoning, fires, and even environmental pollution accidents. According to statistics, gas leak accidents account for more than 30% of industrial gas accidents, and equipment sealing failure is one of the main causes. Therefore, developing efficient and reliable gas leak-proof structures is a key aspect of the safety design of gas generators.

[0003] When traditional gas generators are used to connect pipelines, the gas leakage prevention structure often uses flanges for fixed connection to ensure excellent sealing. However, flange connections are often not suitable for narrow pipelines and require multiple pairs of bolts and nuts for fixing. Pipeline connection structures generally require regular maintenance, and the installation or disassembly maintenance is relatively complicated, reducing the practicality of the sealing structure. Utility Model Content

[0004] To overcome the above-mentioned defects, this utility model provides a gas leak prevention structure for a gas generator. It solves the problem that in the existing technology, when the gas leak prevention structure of the traditional gas generator is applied to the pipeline connection, most of them use flanges for fixed connection to ensure good sealing performance. However, flange connection is often not suitable for narrow pipelines, and multiple pairs of bolts and nuts are required for fixing. The pipeline connection structure generally requires regular maintenance, and the installation or disassembly maintenance is relatively complicated, which reduces the practicality of the sealing structure.

[0005] According to one aspect, at least one embodiment of the present invention provides a gas leak prevention structure for a gas generator, including a first connecting assembly, and further comprising:

[0006] The second connecting component has one end slidably inserted and fixed to the opposite end of the first connecting component;

[0007] A metal spiral wound gasket, wherein the metal spiral wound gasket is disposed between the connection point of the first connecting component and the second connecting component;

[0008] A fixing component is rotatably connected to the outer surface of the first connecting component.

[0009] Preferably, the first connecting component includes a first annular connecting block, and a first annular locking block is fixedly welded to one end of the inner side of the first annular connecting block, and a sealing groove is formed at one end of the first annular locking block near the edge.

[0010] Preferably, two positioning grooves are formed at one end of the first annular connecting block near the edge, and a first fixing short rod is fixedly welded to the outer surface of the first annular connecting block near the edge of the positioning groove. A first limiting block is fixedly welded to the opposite end of each of the two first fixing short rods.

[0011] Preferably, the second connecting component includes a second annular connecting block, a second annular locking block is fixedly welded to the inner edge of the second annular connecting block near one end, a second fixing short rod is fixedly welded to the outer surface of the second annular locking block, the second fixing short rod is fitted into the positioning groove, and a second limiting block is fixedly welded to the opposite end of each of the two second fixing short rods.

[0012] Preferably, the metal spiral wound gasket is placed inside the sealing groove and engaged by a second annular locking block.

[0013] Preferably, the fixing component includes a first clamping block and a second clamping block, and two of each are provided. A through hole is provided on the opposite side of the first clamping block and the second clamping block. The first clamping block and the second clamping block are rotatably connected to the first fixing rod through the through hole. The first clamping block is located on the inner side, and the second clamping block is located on the outer side, and the first clamping block and the second clamping block are arranged opposite to each other.

[0014] Preferably, the top of the front side of the first clamping block and the second clamping block near the through hole are both provided with clamping grooves, and the front side of the first clamping block and the second clamping block near the clamping groove are both provided with opening grooves. The clamping grooves and opening grooves are slidably fitted with the second fixed short rod, and the bottom of the front side of the first clamping block and the second clamping block near the through hole are both fixedly connected with half bolts.

[0015] Preferably, a matching groove is provided on one side of the two second clamping blocks near the edge of the half bolt, an arc-shaped handle is fixedly connected between the opposite sides of the two first clamping blocks near the bottom edge, and a fastening nut is threaded between the outer surfaces of the two opposite half bolts.

[0016] The beneficial effects of the embodiments of this utility model are as follows:

[0017] In this utility model, by fitting and connecting the first connecting component and the second connecting component, the first clamping block and the second clamping block can be rotated and closed simultaneously by bending the arc handle inward. With the clamping groove, the second fixed short rod will be pushed into the first annular connecting block, thereby causing the second annular block to squeeze the metal spiral wound gasket placed inside the sealing groove. Under the elastic action of the metal spiral wound gasket, it will deform, thereby improving the sealing performance. When the fitting groove and the half bolt fixed on the second clamping block are combined, the threaded grooves on the surfaces of the two half bolts can be threaded with a fastening nut to complete the fixation.

[0018] Conversely, during disassembly, by turning the arc-shaped handle, the second fixed short rod, the second annular connecting block, and the second annular locking block can be driven out from the inside of the first annular connecting block through the clamping groove. This eliminates the need for excessive bolts and nuts during the docking process, improving the convenience of installation, disassembly, and maintenance. Attached Figure Description

[0033] like Figures 1-6 As shown, it illustrates a gas leak prevention structure for a gas generator according to an embodiment of the present invention, including a first connecting assembly 1, and further comprising:

[0034] The second connecting component 2 has one end slidably inserted and fixed to the opposite end of the first connecting component 1;

[0035] Metal spiral wound gasket 3 is disposed between the connection point of the first connecting component 1 and the second connecting component 2;

[0036] Fixing component 4 is rotatably connected to the outer surface of the first connecting component 1.

[0037] In this embodiment, the rotation of the fixing component 4 can drive the second connecting component 2 to connect relative to the first connecting component 1. When the right-angle rotation is completed so that the fixing component 4 is in contact with one side of the first connecting component 1, the tightness of the first connecting component 1 and the second connecting component 2 is achieved. The metal spiral wound gasket 3 provides good resilience and excellent sealing performance, and is resistant to high temperature and high pressure.

[0038] like Figures 1-4 As shown, it illustrates a first connecting component 1, a second connecting component 2, and a metal spiral wound gasket 3 in another embodiment of the present invention. The first connecting component 1 includes a first annular connecting block 11. A first annular locking block 12 is fixedly welded to one end of the inner side of the first annular connecting block 11. A sealing groove 13 is provided at one end of the first annular locking block 12 near the edge. Two positioning grooves 14 are provided opposite to each other at one end of the first annular connecting block 11 near the edge. A first fixing short rod 15 is fixedly welded to the outer surface of the first annular connecting block 11 near the edge of the positioning groove 14. A first limiting block 16 is fixedly welded to the opposite end of each of the two first fixing short rods 15.

[0039] The second connecting component 2 includes a second annular connecting block 21. A second annular locking block 22 is fixedly welded to the inner edge of the second annular connecting block 21 near one end. A second fixing short rod 23 is fixedly welded to the outer surface of the second annular locking block 22. The second fixing short rod 23 is fitted into the positioning groove 14. A second limiting block 24 is fixedly welded to the opposite end of each of the two second fixing short rods 23. The metal spiral wound gasket 3 is placed inside the sealing groove 13 and engaged by the second annular locking block 22.

[0040] In this embodiment, the first annular locking block 12 and the sealing groove 13 provide a slot for installing the metal spiral wound gasket 3. When the first annular connecting block 11 and the second annular connecting block 21 are installed together, the metal spiral wound gasket 3 can be squeezed by the engagement of the second annular locking block 22 and the sealing groove 13, thereby increasing the sealing performance. The positioning groove 14 and the second fixing short rod 23 are engaged to achieve the positioning effect, thereby improving the stability of the connection between the first connecting component 1 and the second connecting component 2.

[0041] like Figures 1-6 As shown, a fixing component 4 is shown in another embodiment of the present invention. The fixing component 4 includes a first clamping block 41 and a second clamping block 42. Two of each of the first clamping block 41 and the second clamping block 42 are provided. A through hole 43 is provided on the opposite side of the first clamping block 41 and the second clamping block 42. The first clamping block 41 and the second clamping block 42 are rotatably connected to the first fixing short rod 15 through the through hole 43. The first clamping block 41 is provided on the inner side and the second clamping block 42 is provided on the outer side, and the first clamping block 41 and the second clamping block 42 are arranged opposite to each other.

[0042] The first clamping block 41 and the second clamping block 42 are both provided with clamping grooves 44 through the top of the front side near the through hole 43. The first clamping block 41 and the second clamping block 42 are both provided with opening grooves 45 through the front side near the clamping grooves 44. The clamping grooves 44 and the opening grooves 45 are slidably fitted with the second fixed short rod 23. The first clamping block 41 and the second clamping block 42 are both fixedly connected with half bolts 46 at the bottom of the front side near the through hole 43. The two second clamping blocks 42 are provided with fitting grooves 47 at the edge of the half bolts 46 on one side. The two first clamping blocks 41 are fixedly connected with arc-shaped handles 48 at the bottom edge between the opposite sides of the two first clamping blocks 41. The outer surfaces of the two opposite half bolts 46 are threaded with fastening nuts 49.

[0043] In this embodiment, the through hole 43 allows both the first clamping block 41 and the second clamping block 42 to be rotatably connected to the outer surface of the first fixed short rod 15. The first limiting block 16 prevents the first clamping block 41 and the second clamping block 42 from demolding during rotation. During installation, the first clamping block 41 and the second clamping block 42 are first laid flat at a 180° angle, aligning the openings 45 on the first clamping block 41 and the second clamping block 42. The second fixed short rod 23 is then pushed into the clamping groove 44 through the opening 45. The arc-shaped handle 48 allows the first clamping block 41 and the second clamping block 42 to rotate inwards and close simultaneously. The clamping groove 44 provides space for the second fixed short rod 23. The force pushing the first annular connecting block 11 into the interior causes the second annular locking block 22 to compress the metal spiral wound gasket 3 placed inside the sealing groove 13. Under the elastic action of the metal spiral wound gasket 3, deformation occurs, thereby improving the sealing performance. When the half bolt 46 fixed on the first clamping block 41 merges with the half bolt 46 fixed on the second clamping block 42 through the mating groove 47, the threaded grooves on the surfaces of the two half bolts 46 can be threaded with a fastening nut 49 to complete the fixation. Conversely, when disassembling, by turning the arc-shaped handle 48, the second fixing short rod 23, the second annular connecting block 21, and the second annular locking block 22 can be driven out from the interior of the first annular connecting block 11 through the clamping slide groove 44. The installation and disassembly methods are simple and convenient, and the sealing performance is strong.

[0044] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
