[0003] When performing pressurized sealing of leaking gas pipelines, it is difficult to repair the rupture due to the pressure of the gas. Usually, it is necessary to use sealing components to temporarily seal the pipeline. However, the sealing effect of existing sealing components is limited and the sealing effect is poor. Utility Model Content

[0004] The purpose of this utility model embodiment is to provide a special component for gas leak sealing, which aims to solve the problems mentioned in the background art.

[0005] This utility model embodiment is implemented as follows: a special component for gas leak sealing includes a gas pipeline, two clamps that are interlocked and installed on the outside of the gas pipeline, and a leak sealing unit installed on one of the clamps. The gas pipeline has a hole on its surface. Fixing plates are fixedly installed on both sides of the clamps. A sealing groove is opened on the inner side of the clamps. The sealing groove is filled with sealant. Multiple glue injection grooves are fixedly opened on the fixing plates. The glue injection grooves are connected to the sealing grooves. Multiple fixing holes are fixedly opened in the fixing plates. A mounting base is fixedly installed on the surface of one of the clamps. A vent hole is opened in the mounting base. The leak sealing unit includes a leak sealing bolt, which is movably installed in the vent hole.

[0006] As a further embodiment of this utility model: the sealing groove includes an arc-shaped groove and a straight groove, the arc-shaped groove is formed at both ends inside the clamping plate, and the straight groove is formed at both sides inside the clamping plate.

[0007] As a further embodiment of this utility model: the arc-shaped groove is configured as a groove with a semi-circular cross-section, and the straight groove is configured as a groove with a 90° sector cross-section.

[0008] As a further embodiment of this utility model: positioning blocks and positioning grooves are symmetrically arranged on the fixing plates on both sides of the clamping plate, the positioning blocks and positioning grooves are the same size, and the positioning blocks and positioning grooves on the clamping plate are respectively engaged in the positioning grooves and positioning blocks on the other clamping plate.

[0009] As a further embodiment of this utility model: the leak-sealing unit further includes an air guide bolt, which includes a bolt body and an air guide tube, and the external dimensions of the bolt body are the same as those of the leak-sealing bolt.

[0010] As a further embodiment of this utility model: the air guide hose is movably installed inside the bolt body, the air guide hose is made of elastic material, the air guide hose is a tubular structure, the bolt body is provided with an air guide hole corresponding to the air guide hose, and the lower end of the air guide hose corresponding to the gas pipeline surface is set as an arc surface.

[0011] The beneficial effects of this utility model are as follows:

[0012] 1. This utility model provides a special component for sealing gas leaks. Two clamping plates interlock and are secured to the surface of a gas pipeline using bolts and nuts via fixing holes. Sealant is injected into the sealing groove through an injection groove. After the sealant solidifies, it fills and seals all gaps in the clamping plates, resulting in a better sealing effect compared to existing leak-sealing devices. The leak-sealing bolt is then screwed into the vent hole to complete the sealing of the gas pipeline leak. During installation, the vent hole can be aligned with the leak, so that the leaked gas mainly exits from the vent hole, reducing the impact on the solidification of the sealant.

[0013] 2. The gas leak sealing component provided in this embodiment of the utility model uses positioning grooves and positioning blocks on two clamping plates to interlock with each other, which facilitates the positioning and installation of the clamping plates, thereby ensuring that the sealing grooves and glue injection grooves on the two clamping plates can fit well together.

[0014] 3. The gas sealing component provided in this embodiment of the present invention, by means of a gas guide bolt, can be installed into the vent hole when injecting adhesive into the sealing groove. The gas guide tube squeezes the outer area of ​​the rupture hole, so that the rupture hole can and can only vent through the gas guide tube and the gas guide hole, which greatly reduces the influence of gas pressure on the solidification of the sealant.

The leak-sealing unit 3 includes a leak-sealing bolt 31, which is movably installed in the vent hole 26.

[0022] In one embodiment of this utility model, two clamping plates 2 are interlocked and fixed to the surface of the gas pipeline 1 at the hole 11 using bolts and nuts, and sealant is injected into the sealing groove 22 through the injection groove 23. After the sealant solidifies, it fills and seals all gaps in the clamping plates 2. Compared with existing leak-stopping devices, the sealing effect is better. Then, the leak-stopping bolt 31 is screwed into the vent hole 26 to complete the sealing of the gas pipeline leak. During installation, the vent hole 26 can also be aligned with the hole 11. At this time, the leaked gas is mainly discharged from the vent hole 26, reducing the impact on the solidification of the sealant.

[0023] like Figure 2 and Figure 3As shown, in another embodiment of the present invention, the sealing groove 22 includes an arc-shaped groove 221 and a straight groove 222. The arc-shaped groove 221 is formed at both ends inside the clamping plate 2, and the straight groove 222 is formed at both sides inside the clamping plate 2.

[0024] Specifically, the arc-shaped groove 221 is configured as a groove with a semi-circular cross-section, and the straight groove 222 is configured as a groove with a 90° sector cross-section.

[0025] In one embodiment of this utility model, by setting the straight groove 222 as a groove with a cross-section of 90° sector, after the two clamping plates 2 are engaged with each other, the straight grooves 222 in the upper and lower clamping plates 2 fit together to form a groove with a cross-section of semi-circular. Through the set arc groove 221 and straight groove 222, all gaps connecting the clamping plate 2 to the outside are covered, leaving only the vent hole 26, thereby facilitating the sealing effect by sealing the vent hole 26.

[0026] like Figure 2 As shown, in another embodiment of the present invention, positioning blocks 27 and positioning grooves 28 are symmetrically arranged on the fixing plates 21 on both sides of the clamping plate 2. The positioning blocks 27 and positioning grooves 28 are the same size. The positioning blocks 27 and positioning grooves 28 on the clamping plate 2 are respectively engaged in the positioning grooves 28 and positioning blocks 27 on another clamping plate 2.

[0027] In one embodiment of this utility model, the positioning grooves 28 and positioning blocks 27 provided on the two clamping plates 2 engage with each other, which facilitates the positioning and installation of the clamping plates 2, thereby ensuring that the sealing grooves 22 and the glue injection grooves 23 on the two clamping plates 2 can fit well together.

[0028] like Figure 2 and Figure 3 As shown, in another embodiment of the present invention, the leak-sealing unit 3 further includes an air guide bolt 32, which includes a bolt body 321 and an air guide tube 322. The external dimensions of the bolt body 321 are the same as those of the leak-sealing bolt 31.

[0029] Specifically, the air guide hose 322 is movably installed inside the bolt body 321. The air guide hose 322 is made of elastic material and has a tubular structure. The bolt body 321 has an air guide hole 3211 corresponding to the air guide hose 322. The lower end of the air guide hose 322 is set as an arc surface on the surface of the gas pipeline 1.

[0030] In one embodiment of this utility model, by means of the provided air guide bolt 32, when injecting adhesive into the sealing groove 22, the air guide bolt 32 can be installed into the vent hole 26, and the air guide tube 322 squeezes the outer area of ​​the contact hole 11, so that the hole 11 can and can only vent through the air guide tube 322 and the air guide hole 3211, which greatly reduces the influence of gas pressure on the solidification of sealant.
