[0023] The technical solution of the present invention will be clearly and completely described below in conjunction with the drawings in the present invention. In addition, the forms of the various structures recorded in the following embodiments are merely illustrative. The pressure pipeline inspection tool involved in the present invention is not limited to the various structures recorded in the following embodiments. All other implementations obtained by ordinary technicians in this field without making creative work belong to the scope of protection of the present invention.

[0024] Reference Figure 1-5The utility model provides a pressure pipeline inspection tool, including a sealing component, the sealing component includes a sealing airbag 1, two sealing airbags 1 are arranged side by side and at intervals, an inflation tube 2 is fixedly installed in the middle of each sealing airbag 1, and one end of each inflation tube 2 penetrates the sealing airbag 1 on the corresponding side and extends between the two sealing airbags 1, and the other end of each inflation tube 2 is connected to a connecting tube 12, and at the same time, the ends of the two connecting tubes 12 away from the inflation tube 2 are connected to a first air supply tube 3, a pressure gauge 4 is installed on the first air supply tube 3, and the end of the first air supply tube 3 away from the inflation tube 2 is connected to an external air compressor, and the sealing airbag 1 is equipped with an inflation component, and the inflation of the sealing airbag 1 is achieved by the inflation component.

[0025] When in use, first insert two sealing airbags 1 from both ends of the pipe to be tested, and then use the inflatable component to inflate the sealing airbags 1. The inflated sealing airbags 1 will fill the inner wall of the pressure pipe, thus achieving the sealing of the inside of the pressure pipe. Then let the air compressor inflate the first air supply pipe 3. At this time, high-pressure air will be filled into the pressure pipe through the connecting pipe 12 and the inflation pipe 2 until the pressure value displayed on the pressure gauge 4 reaches the test requirement. Observe whether there is any leakage on the surface of the pressure pipe. In this way, the entire inspection work can be completed.

[0026] The sealing airbag 1 is conical and made of elastic material. A mounting groove 5 is provided around the outer wall of the sealing airbag 1. An elastically stretchable sealing ring 6 is embedded in the mounting groove 5. This ensures that the sealing airbag 1 can completely seal the pressure pipe.

[0027] The inflatable component includes a sub-cavity 7, which is opened in the tube wall of the inflation tube 2. An air outlet hole 8 is opened on the surface of the inflation tube 2, and the air outlet hole 8 is connected to the sub-cavity 7. An air injection tube 9 is fixedly installed on the inflation tube 2, and the air injection tube 9 is connected to the sub-cavity 7. The air outlet hole 8 is only opened on the surface of the inflation tube 2 inside the sealed airbag 1. At the same time, there are multiple air outlet holes 8, which are linearly and evenly arranged. The ends of the two air injection tubes 9 away from the inflation tube 2 are connected to the second air supply tube 10, and the end of the second air supply tube 10 away from the air injection tube 9 is connected to an external air compressor. In this way, only an external air compressor is needed to inflate the second air supply tube 10, and high-pressure air will enter the sealed airbag 1 from the air injection tube 9 through the sub-cavity 7 and the air outlet hole 8 to make the sealed airbag 1 inflate.

[0028] The second air supply pipe 10 is fixedly provided with a second valve 11, which controls the on-off of the second air supply pipe 10. Thus, closing the second valve 11 can keep the sealing airbag 1 pressurized to maintain the closed state of the pressure pipe.

[0029] A first valve 13 is fixedly installed on the first air supply pipe 3, and the first valve 13 controls the on-off of the first air supply pipe 3. In this way, by closing the first valve 13, the air pressure inside the pressure pipe can be kept constant. The pressure gauge 4 is located between the first valve 13 and the connecting pipe 12.

[0030] Therefore, the complete usage process is to first insert two sealing air bags 1 from both ends of the pipeline to be tested, then start the external air compressor to inflate the second air supply pipe 10, and open the second valve 11. At this time, high-pressure air will enter the sealing air bag 1 from the air injection pipe 9 through the air chamber 7 and the air outlet 8 to make the sealing air bag 1 swell. The inflated sealing air bag 1 will fill the inner wall of the pressure pipe. In this way, the sealing of both ends of the pressure pipe is achieved. Then close the second valve 11, and let the air compressor inflate the first air supply pipe 3, and open the first valve 13 at the same time. At this time, high-pressure air will pass through the connecting pipe 12 and the inflation pipe 2 to fill the inside of the pressure pipe until the pressure value displayed on the pressure gauge 4 reaches the test requirement, and then close the first valve 13. At this time, observe whether there is any leakage on the surface of the pressure pipe through the pressure gauge 4. In this way, the entire inspection work can be completed.

[0031] In summary, during the entire use process, the sealing airbag 1 is inserted into the two ends of the pipe to seal the two ends of the pressure pipe. Under this structure, it can be ensured that the surface of the sealing airbag 1 is in contact with the smooth inner wall of the pipe. In this way, it can be effectively compatible with various pipes with uneven ends, thereby greatly improving the applicability of the entire tooling.

[0032] At the same time, during the entire use process, the user can change the volume of the sealing airbag 1 by changing the gas pressure injected into the inner wall of the second air supply pipe 10. In this way, it can effectively be compatible with a variety of pipes with different diameters, thereby further improving the applicability of the entire tooling.

[0033] In addition, since the components of the entire tooling are mostly soft pipes and elastic sealing airbags 1, the entire tooling can change its shape freely to a certain extent, which will be compatible with different usage terrains and further improve the applicability of the entire tooling.

[0034] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
