[0022] In this embodiment, as Figure 2 As shown, the sealing assembly 6 includes an outer cylinder 7, a gas inlet 8, a telescopic rod 9, a triangular connecting block 10, an internal hose 11, a sliding groove 12, a central shaft 13, a triangular clamping block 14, a sealing round block 15, an inflatable rubber ring 16, a first hose perforation 17, a second hose perforation 18, a gas nozzle 19, and a dispersing net 20. The outer cylinder 7 is detachably connected to the upper outer surface of the special plate valve 3. The upper outer surface of the outer cylinder 7 has a gas inlet 8. The upper inner surface of the outer cylinder 7 is fixedly connected to the telescopic rod 9, and the lower outer surface of the telescopic rod 9 is fixedly connected to the triangular connecting block 10. The telescopic rod 9 can drive the triangular connecting block 10 to move from top to bottom inside the outer cylinder 7. When the triangular connecting block 10 is about to reach the bottom of the inner wall of the gas pipeline 1, the two sets of triangular clamping blocks 14 and sealing round blocks 15, which are movably connected to the triangular connecting block 10, move simultaneously towards both ends of the gas pipeline 1, thereby forming two seals on the gas pipeline 1 and improving the sealing effect of the gas pipeline 1.

[0023] In this embodiment, as Figures 3-4As shown, the inner cavity of the telescopic rod 9 is movably fitted with a built-in flexible hose 11. A sliding groove 12 is formed on the outer surface of one front end of the triangular connecting block 10. There are two sets of sliding grooves 12. A central shaft 13 is movably connected to the inner cavity of the two sets of sliding grooves 12. A triangular clamping block 14 is movably fitted onto the outer wall of the central shaft 13. A sealing round block 15 is fixedly connected to the outer surface of one end of the triangular clamping block 14. An inflatable rubber ring 16 is fixedly fitted onto the outer wall of the sealing round block 15. First flexible hose perforations 17 are formed on both outer surfaces of the triangular connecting block 10. A second flexible hose perforation 18 is formed on one outer surface of the sealing round block 15. An air nozzle 19 is fixedly connected to the outer wall of the sealing round block 15. There are several sets of air nozzles 19. The nozzle 19 has a fixedly connected dispersion net 20 inside. It can move easily inside the outer cylinder 7 and the gas pipeline 1 through two sets of smaller sealing blocks 15. The gas-filled rubber ring 16 on the outer wall of the sealing block 15 can seal the inside of the gas pipeline 1 more tightly after being inflated. When the sealing block 15 enters the designated position inside the gas pipeline 1, the gas is delivered from the gas inlet 8 through the built-in hose 11 into the sealing block 15 and sprayed into the inflatable rubber ring 16 through the gas nozzle 19. The multiple sets of gas nozzles 19 and dispersion net 20 can deliver the gas into the inflatable rubber ring 16 more evenly, so that the inflatable rubber ring 16 can expand more evenly.

[0024] Working principle:

[0025] When using this product, the telescopic rod 9 can drive the triangular connecting block 10 to move from top to bottom inside the outer cylinder 7. When the triangular connecting block 10 is about to reach the bottom of the inner wall of the gas pipeline 1, the two sets of triangular clamping blocks 14 and the sealing round blocks 15, which are movably connected to the triangular connecting block 10, move simultaneously towards both ends of the gas pipeline 1, thereby forming two seals on the gas pipeline 1, which can improve the sealing effect of the gas pipeline 1. In addition, the two sets of smaller sealing round blocks 15 can be easily moved between the outer cylinder 7 and the inside of the gas pipeline 1. Furthermore, the inflatable rubber ring 16 installed on the outer wall of the sealing block 15 can more tightly seal the inside of the gas pipeline 1 after being inflated. When the sealing block 15 enters the designated position inside the gas pipeline 1, the gas is delivered from the gas inlet 8 through the built-in hose 11 into the sealing block 15, and sprayed into the inflatable rubber ring 16 through the gas nozzle 19. The multiple sets of gas nozzles 19 and the dispersion net 20 can deliver the gas into the inflatable rubber ring 16 more evenly, so that the inflatable rubber ring 16 can expand more evenly.
