Technical Field

[0001] This utility model relates to the field of pipe end sealing technology, and in particular to a leak-proof oil pipe end sealing component. Background Technology

[0002] Oil pipe seals are critical components used at the connections of oil pipelines, valves, and equipment interfaces. They prevent leakage of media such as oil and natural gas through physical isolation and elastic deformation, ensuring the safe operation of the system. Oil pipe seals include elastic seals, metal seals, and packing seals.

[0003] Existing oil pipe nozzle seals use a sleeve to connect two pipe bodies, and a metal sealing ring is set between the pipe body end face and the sleeve to prevent leakage. However, the sleeve is prone to deformation, and deformation at one end of the sleeve will cause the nozzle seal to fail, resulting in inconvenience and high cost of nozzle seals.

Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0030] Example 1

[0031] Please see Figure 1-5 This utility model provides a technical solution: a leak-proof oil pipe nozzle seal, comprising:

[0032] The first sealing assembly 1 includes a first inner sealing ring 11, a first rubber gasket 12, and a first sealing seat 13. The first inner sealing ring 11 is provided with a first annular groove 111. The end of the first tube 9 is inserted into the first annular groove 111. The first sealing seat 13 is fitted on the outside of the first inner sealing ring 11. The end of the first inner sealing ring 11 extends out of the first sealing seat 13 to form a first annular protrusion 112. The first rubber gasket 12 is disposed between the first inner sealing ring 11 and the first sealing seat 13. The first sealing seat 13 is provided with a first locking bolt 14. The first locking bolt 14 is threadedly connected to the first sealing seat 13, and the end of the first locking bolt 14 contacts the surface of the first tube 9.

[0035] The locking piece 4 is located on the outside of the first sealing seat 13. The end of the locking piece 4 extends to the outside of the second sealing assembly 2. The first locking bolt 14 passes through the locking piece 4 and is threaded onto the first sealing seat 13. The second locking bolt in the second sealing assembly 2 fixes the locking piece 4 in the same way as the first locking bolt 14.

[0036] The structure of the second sealing assembly 2 is the same as that of the first tube 9. The installation of the second sealing assembly 2 and the second tube 8 is the same as the installation of the first sealing assembly 1 and the first tube 9.

[0037] To improve the connection between the first inner sealing ring 11 and the first tube body 9, an interference fit can be used. The same principle applies to the fit between the second sealing assembly 2 and the second tube body 8.

[0038] The first sealing seat 13 is provided with three circumferentially arranged first locking bolts 14.
