Description

Technical Field

[0001] The utility model relates to the technical field of repair airbags, and in particular to a heating airbag capable of assisting the curing of CIPP local repair resin. Background Art

[0002] Pipeline is a device connected by pipes, pipe connectors and valves for transporting gas, liquid or fluid with solid particles. Pipeline is widely used, mainly in water supply, drainage, heating, gas supply, long-distance transportation of oil and natural gas, agricultural irrigation, hydraulic engineering and various industrial devices. Therefore, the sealing of pipeline is very important. When there is a leak in the inner wall of the pipeline, it is necessary to use a repairer to repair the inner wall of the pipeline.

[0003] The existing fixer has the following problems:

[0004] Current repair devices all use a repair airbag to wrap glass fiber cloth around its exterior, place the repair airbag at the leak, inflate it to press the glass fiber cloth against the inner wall of the pipe, and use the resin inside the fiber cloth to solidify at the leak to complete the repair of the pipe. However, in winter, due to the influence of the outside temperature, the solidification time of the resin is prolonged, which increases the time for pipe repair, resulting in low construction efficiency. In addition, the air pressure inside the airbag needs to remain unchanged while the resin is solidifying so that the glass fiber cloth can continue to cling to the inner wall of the pipe. After solidification is completed, the gas filled inside needs to be completely released before it can be removed to reduce the wear of the repair airbag.

[0005] In view of the above problems, we propose a heating airbag that can assist the curing of CIPP local repair resin. Utility Model Content
