It is explicitly and implicitly understood by those skilled in the art that the embodiments described in the present application can be combined with other embodiments.

[0029] In the related art, when the gas pipeline has defects such as pinholes or cracks, the common repair method is welding repair, but welding repair consumes a long time and has a certain operation difficulty.

[0030] Based on this, the embodiments of the present application provide a gas pipeline repair structure to solve the above technical problems. The gas pipeline repair structure provided by the embodiments of the present application is introduced below.

[0031] As shown in Figs. 1 to 3 The present application provides a gas pipeline repair structure, which comprises a sticking part 10, a repair panel 20 and a fixing part 30.

[0032] The sticking part 10 is used for sticking the gas pipeline, and the sticking part 10 comprises a protective layer 11, a filler layer 12, a sticking layer 13 and a release layer 14. The thickness of the protective layer 11 is set to be between 3mm-8mm, for example, the thickness of the protective layer 11 can be 5mm, so that it has a certain protective property and is beneficial to increase the strength of the sticking part 10. The protective layer 11 is made of fluororubber material. Fluororubber has chemical resistance and heat resistance, which can have good resistance to most chemicals (acid, alkali, solvent, oil), and fluororubber can be used for a long time at a temperature as high as 250°C, and can withstand higher temperature for a short time, so that the protective layer 11 will not deform when the filler layer 12 is heated.

[0033] The adhesive layer 13 is connected to the protective layer 11, and the adhesive layer 13 is made of hot melt adhesive material, so that the adhesive layer 13 and the gas pipeline are bonded in a short time, realizing rapid repair, and the bonding strength of the hot melt adhesive is high. Specifically, the adhesive layer 13 can use polyester or polyethylene and other hot melt adhesives with a melting point usually between 100°C and 150°C.

[0034] The filler layer 12 is arranged between the protective layer 11 and the adhesive layer 13, and the filler layer 12 protrudes away from the protective layer 11, and the filler layer 12 is filled with filler, and the filler is made of thermosetting material, for example, the filler layer 12 is made of epoxy resin material, and the epoxy resin has a certain viscosity at room temperature, and is in a state of paste or viscous liquid, and has fluidity. The position where the adhesive layer 13 and the filler layer 12 are connected is provided with a cut, specifically, the cut is usually formed during use, that is, the adhesive layer 13 is cut by a sharp object during use, and the length of the cut can be set to between 5mm and 20mm, and should not be too large. In addition, the cut is a linear cut or a cross-shaped cut.

[0035] The thickness of the adhesive layer 13 is set to between 1mm and 3mm, and the thickness of the filler layer 12 is set to between 3mm and 12mm, for example, the thickness of the adhesive layer 13 is 3mm, and the thickness of the filler layer 12 is 10mm, so that the filler layer 12 protrudes away from the protective layer 11, so that the filler can flow out after being extruded. In addition, the remaining connection positions of the adhesive layer and the protective layer 11 can be bonded by glue, so as to avoid the filler entering between the adhesive layer and the protective layer 11 when the filler layer 12 is extruded.

[0036] The protruding height of the filler layer 12 is 3mm-5mm, and the filler layer 12 is located in the central area of the protective layer 11, so that the filler layer 12 can be uniformly stressed, and flow to the periphery of the cut, so as to better fill the pinholes or cracks.

[0037] The release layer 14 is connected to the adhesive layer 13, and the release layer 14 can be a plastic film, which is removed during use.

[0038] The repair panel 20 has a predetermined thickness, for example, the thickness of the repair panel 20 is 5mm, and the repair panel 20 is an arc-shaped plate, and the repair panel 20 is used to cover the adhesive part 10. The side of the repair panel 20 away from the adhesive part 10 is provided with a plurality of cut grooves 22 extending along the length direction of the repair panel 20, so as to form a plurality of ribs 21 on the repair panel 20, and the depth of the cut groove 22 is at least half of the thickness of the repair panel 20, so as to facilitate the bending of the repair panel 20, so that it can be attached to the adhesive part 10, and can match other sizes of gas pipelines.

[0039] The repair panel 20 is made of stainless steel or titanium alloy material, so that the repair panel 20 has high strength and toughness, and can improve the corrosion resistance of the repair panel 20.

[0040] The fixing part 30 at least comprises a first hoop 31 and a second hoop 32, the first hoop 31 and the second hoop 32 are sleeved on the gas pipeline and cover the repair panel 20, so as to fix the repair panel 20 on the gas pipeline. Specifically, the first hoop 31 and the second hoop 32 can be respectively arranged at two ends of the repair panel 20.

[0041] In addition, the fixing part 30 further comprises a third hoop 33, the third hoop 33 is sleeved on the gas pipeline and covers the position on the repair panel 20 corresponding to the filler layer 12. The third hoop 33 can increase the extrusion force of the repair panel 20 on the filler layer 12, so that the filler can plug the pinhole or the crack. Specifically, the width of the third hoop 33 can be greater than that of the first hoop 31 and the second hoop 32.

[0042] The implementation principle of the gas pipeline repair structure of the embodiment is as follows:

[0043] When repairing the pipeline, the release layer 14 is removed, a cut is arranged at the position of the adhesive layer 13 corresponding to the filler layer 12, the protruding filler layer 12 is aligned with the pinhole or the crack of the gas pipeline, and the adhesive layer 13 covers the gas pipeline. Then, the repair panel 20 is covered on the protective layer 11, the first hoop 31 and the second hoop 32 are fixed at two ends of the repair panel 20, and the third hoop 33 is arranged at the position of the repair panel 20 corresponding to the filler layer 12, i.e. the middle position of the repair panel 20. The filler in the filler layer 12 flows out from the cut after being extruded by the repair panel 20, so as to plug the pinhole or the crack. Then, the adhesive layer 13 and the filler layer 12 are heated, the adhesive layer 13 is bonded to the gas pipeline after being heated, and the filler is solidified after being heated, so as to plug the pinhole or the crack and achieve the repair. The repair structure has a simple operation process, and can quickly and easily repair the gas pipeline.

[0044] The above is only a specific implementation of the present application, and those skilled in the art can clearly understand that, for the convenience and brevity of description, the specific working process of the above-described system, module and unit can refer to the corresponding process in the foregoing method embodiments, which will not be described here.
