Description

Technical Field

[0001] This utility model relates to the field of PVC-C liner technology, and in particular to a multi-segment spliced ​​PVC-C liner. Background Technology

[0002] PVC-C piping systems (known internationally as CPVC) have high mechanical strength at high temperatures, making them suitable for pressure applications. They can operate at temperatures up to approximately 90 degrees Celsius and have a lifespan of up to 50 years. They are safe and easy to use, and are commonly used for the protection of high-voltage cables. However, existing PVC-C liner systems have at least the following drawbacks: 1. Existing PVC-C liner systems are not easy to splice into multiple sections; 2. Existing PVC-C liner systems are prone to friction with cables during the support and protection process. Therefore, we have introduced a new multi-section splicing type PVC-C liner system. Utility Model Content

[0025] Please see Figure 1-4 This utility model provides a technical solution:

[0026] A multi-segment spliced ​​PVC-C liner includes a support pipe 1, a connecting pipe 2 sleeved at the upper end of the support pipe 1, a corrosion-resistant layer 4 installed on the outer surface of both the support pipe 1 and the connecting pipe 2, a number of connecting screws 3 interlaced in a ring array between the support pipe 1 and the connecting pipe 2, a second connecting ring 6 fixedly sleeved on the lower part of the outer surface of the support pipe 1, and a first connecting ring 5 fixedly sleeved on both the upper and lower parts of the outer surface of the connecting pipe 2.

[0027] In this embodiment, the support tube 1 includes a first tube body 11. A third connecting ring 14 is fixedly sleeved on the upper part of the outer surface of the first tube body 11. A first annular groove 13 is opened on the upper part and the lower part of the inner tube wall of the first tube body 11. A plurality of insert rods 12 are fixedly connected to the upper end of the first tube body 11 in an annular array. The first tube body 11 is fixedly connected to the connecting tube 2. The plurality of insert rods 12 are all inserted and connected to the connecting tube 2.

[0028] The above solution involves setting two annular slots 13 and several insert rods 12 on the support pipe 1, with the insert rods 12 all inserted and connected to the connecting pipe 2, thereby strengthening the connection between the connecting pipe 2 and the support pipe 1.

[0029] In this embodiment, the connecting pipe 2 includes a second pipe body 21. The upper part and the lower part of the inner wall of the second pipe body 21 are both provided with a second annular groove 22. A splicing ring 23 is inserted and connected to the inner wall of the lower second annular groove 22. The second pipe body 21 is fixedly connected to the first connecting ring 5. The splicing ring 23 is inserted and connected to the upper first annular groove 13. A rubber layer 24 is installed on the inner annular walls of both the second pipe body 21 and the first pipe body 11.

[0030] The above scheme involves interlocking the splicing ring 23 with the lower second annular groove 22 on the connecting pipe 2 and the upper first annular groove 13 on the support pipe 1, and connecting the support pipe 1 and the connecting pipe 2 together by interlocking several connecting screws 3 with the lower first connecting ring 5 and third connecting ring 14, thereby extending the PVC-C liner and improving stability. The rubber layer 24 installed inside the support pipe 1 and the connecting pipe 2 can provide wear-resistant protection for the cable support process.

[0031] It should be noted that this utility model is a multi-segment splicing PVC-C liner. In use, the PVC-C liner consists of a support pipe 1 and a connecting pipe 2, which are connected by a splicing ring 23. The splicing ring 23 is inserted into the first annular groove 13 on the upper part of the support pipe 1 and the second annular groove 22 on the lower part of the connecting pipe 2. This design allows different segments of the liner to be tightly connected together, forming a continuous and stable pipeline system. The splicing ring 23 is then inserted into the second annular groove 22 on the lower part of the connecting pipe 2 and the first annular groove 13 on the upper part of the support pipe 1, and then the connecting pipe 2 is... The second pipe body 21 on the connector 2 is sleeved with several insertion rods 12, and several connecting screws 3 pass through the first connecting ring 5 and the third connecting ring 14 at the bottom to connect the support pipe 1 and the connecting pipe 2 together, so as to extend the connection of the PVC-C liner and improve stability. In order to enhance the wear resistance protection of the liner for the cable, a rubber layer 24 is provided inside the support pipe 1 and the connecting pipe 2. The rubber layer 24 has good elasticity and wear resistance, which can provide effective buffering and support when the cable passes through the liner, reduce the friction and wear between the cable and the inner wall of the liner, thereby extending the service life of the cable and the liner.
