[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0021] Reference Figure 1-Figure 3The utility model provides an embodiment of a PVC double-sealed pipe, comprising a pipe body 1, a sleeve 2 being provided on the pipe body 1, a first sealing ring 3 being provided on the sleeve 2, a sleeve 2 being provided on the first sealing ring 3, a sleeve 2 being provided on the first sealing ring 3, a second sealing ring 5 being provided on the sleeve 2 4, and a pipe opening 6 being provided on the second sealing ring 5. Through the double-sealing structure design of the pipe body 1, that is, the combined use of the first sealing ring 3 and the second sealing ring 5, the sealing performance of the pipeline is significantly improved, which not only enhances the resistance of the pipeline to external environmental erosion and internal medium corrosion, but also ensures the stability and reliability of the pipeline during long-term operation. Compared with traditional one-way sealing ring pipes, the service life of the pipe body 1 can be extended by more than fifteen years. The double-sealing design of the pipe body 1 ensures a good sealing effect without the need for tedious pressure testing during installation of the pipe body 1, which not only simplifies the installation process but also improves the installation efficiency.

[0022] The outer diameter of the tube body 1 is set to 80 cm, the outer diameter of the sleeve 2 is set to 84 cm, the length of the sleeve 2 is 10 cm, the outer diameter of the first sealing ring 3 is set to 94 cm, the length of the first sealing ring 3 is 5 cm, the outer diameter of the sleeve 2 4 is set to 84 cm, the length of the sleeve 2 4 is 8 cm, the outer diameter of the second sealing ring 5 is set to 94 cm, the length of the second sealing ring 5 is 5 cm, the outer diameter of the pipe mouth 6 is set to 84 cm, the length of the pipe mouth 6 is 8 cm, the shape of the second sealing ring 5 and the first sealing ring 3 is conical, the second sealing ring 5 and the first sealing ring 3 are symmetrically arranged, the sleeve 2 4 is arranged between the first sealing ring 3 and the second sealing ring 5, the tube body 1, sleeve 1 2, the first sealing ring 3, sleeve 2 4, the second sealing ring 5 and the pipe mouth 6 are integrally formed.

[0023] Working principle: When installing the pipe body 1, the double sealing structure of the first sealing ring 3 and the second sealing ring 5 used on the pipe body 1 effectively improves the sealing performance and durability of the pipeline, so that the pipeline can better resist the erosion of the external environment and the corrosion of the internal medium during long-term use, thereby extending the service life of the pipeline. The service life of the double-sealed pipe can be extended by more than fifteen years compared with the one-way sealing ring pipe. Due to its unique double-sealing design, the pipe body 1 does not require a pressure test during the installation process to ensure a good sealing effect, which not only simplifies the installation process and reduces the installation cost, but also improves the installation efficiency.
