Description

Technical Field

[0001] This application relates to the field of pipeline repair technology, and more specifically, to a gas pipeline sealing structure. Background Technology

[0002] With the acceleration of urbanization, the demand for urban gas is constantly increasing, as are the number and length of gas pipelines. However, due to factors such as geological environment, urban construction, and improper use by users, gas leaks can occur during the operation of natural gas pipelines.

[0003] Traditional pipeline repair methods involve depressurizing and venting the leaking section of the pipeline before performing hot work such as cutting, welding, and drilling. Since the pipeline contains gas with a certain pressure and concentration, the construction process inevitably poses many safety hazards to the workers and also pollutes the environment. Utility Model Content

[0004] The purpose of this application is to provide a gas pipeline sealing structure to improve the reliability and safety of gas pipelines.

[0005] This application provides a gas pipeline sealing structure, which adopts the following technical solution:

[0006] A gas pipeline sealing structure includes a repair agent layer, a first protective layer, and a reinforcing layer. The repair agent layer is used to seal leaks in the pipeline. The first protective layer is wrapped around the outside of the pipeline and covers the repair agent layer. An adhesive layer is provided between the first protective layer and the pipeline. The reinforcing layer is disposed outside the first protective layer.

[0007] Preferably, the sealing structure further includes a second protective layer, which includes waterproof tape and two rubber gaskets. The waterproof tape covers the first protective layer and the reinforcing layer. The rubber gaskets are disposed on the outer wall of the pipe. The first protective layer is located between the two rubber gaskets. The end of the waterproof tape is connected to the rubber gasket.

[0008] Preferably, the repair agent layer is made of quick-setting steel glue rod.

[0009] Preferably, the first protective layer is formed by winding multiple layers of glass fiber cloth, and an adhesive layer is provided between two adjacent layers of glass fiber cloth.

[0010] Preferably, the adhesive layer is an epoxy resin liquid.

[0011] Preferably, the reinforcing layer is a strapping band.

[0012] Preferably, an adhesive layer is provided between the reinforcing layer and the first protective layer.

[0013] Compared with the prior art, the beneficial effects of this application are as follows:

[0014] The sealing structure provided in this application first seals the leak point with a repair agent when repairing a pipeline. Then, a first protective layer is wrapped around the outside of the pipeline, which improves the sealing effect at the sealing point. An adhesive layer is provided between the first protective layer and the pipeline, which improves the stability of the connection between the first protective layer and the pipeline. Then, a reinforcement layer is used to reinforce the first protective layer, which further improves the stability of the connection between the first protective layer and the pipeline.

[0027] Example

[0028] like Figure 1-4 As shown in the embodiment of this application, the gas pipeline sealing structure includes a repair agent layer 1, a first protective layer 2, and a reinforcing layer 3. The repair agent layer 1 is used to seal the leakage point of the pipeline 8. The first protective layer 2 is wrapped around the outside of the pipeline 8 and covers the repair agent layer 1. An adhesive layer 4 is provided between the first protective layer 2 and the pipeline 8. The reinforcing layer 3 is provided outside the first protective layer 2.

[0029] When repairing pipe 8, the leak point is first sealed with a repair agent, then the first protective layer 2 is wrapped around the outside of pipe 8, and an adhesive layer 4 is set between the first protective layer 2 and pipe 8. Then, the first protective layer 2 is reinforced with a reinforcing layer 3 to achieve the purpose of rapid leak sealing. Finally, a leak detector or other relevant equipment is used to detect leaks to ensure the reliability and effectiveness of the sealing effect.

[0030] In this embodiment, to further improve the sealing strength and pressure resistance, a second protective layer 5 is also provided. The second protective layer 5 includes a waterproof tape 6 and two rubber gaskets 7. The waterproof tape 6 covers the first protective layer 2 and the reinforcing layer 3. The rubber gaskets 7 are set on the outer wall of the pipe 8 and are bonded to the outer wall of the pipe 8 with adhesive. The rubber gaskets 7 are formed by bonding the ends of rubber strips together. The first protective layer 2 is located between the two rubber gaskets 7. The end of the waterproof tape 6 is connected to the rubber gaskets 7.

[0031] After the reinforcement layer 3 is installed, the rubber gasket 7 is first installed on the pipe 8, and then the waterproof tape 6 is wrapped around it. The waterproof tape 6 is used to reinforce the first protective layer 2. After the installation of the waterproof tape 6 is completed, a closed area is formed between the waterproof tape 6 and the rubber gasket 7, which reduces the possibility of water seepage in the closed area and improves the protective effect of the sealing part.

[0032] In this embodiment, the repair agent layer 1 is made of quick-setting steel glue rod. The quick-setting steel glue rod does not require professional tools and can be operated by hand, making it suitable for emergency repairs. After curing, the quick-setting steel glue rod has high strength, high temperature resistance, corrosion resistance, and can bond tightly to metal.

[0033] In this embodiment, the first protective layer 2 is formed by winding multiple layers of fiberglass cloth. In specific implementation, at least five layers are wound. The fiberglass cloth is used to enhance the pipe structure and has high temperature resistance and insulation properties. An adhesive layer 4 is provided between two adjacent layers of fiberglass cloth. The adhesive layer 4 is used to improve the stability of the fiberglass cloth and ensure the sealing effect of the pipe 8.

[0034] In this embodiment, the adhesive layer 4 is an epoxy resin liquid, which has the functions of structural reinforcement and pipe waterproofing.

[0035] In this embodiment, the reinforcing layer 3 is a strapping strap, which can quickly bind the first protective layer 2 to reinforce the first protective layer 2.

[0036] In this embodiment, an adhesive layer 4 is provided between the reinforcing layer 3 and the first protective layer 2. The adhesive layer 4 is used to improve the stability of the connection between the reinforcing layer 3 and the first protective layer 2.

[0037] The above are merely preferred embodiments of this application and are not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
