Technical Field

[0001] This utility model relates to the technical field of compensators, specifically a corrosion-resistant corrugated sleeve complementary compensator. Background Technology

[0002] An expansion joint, also known as a compensator or expansion valve, is a device used to absorb displacement and deformation of pipes, containers, and other components caused by factors such as temperature changes and mechanical vibration. It mainly consists of bellows, flanges, and seals, utilizing the elastic deformation of the bellows to compensate for thermal expansion and contraction, mechanical displacement, and vibration in the pipeline system, thereby ensuring the normal operation of the pipeline system.

[0003] Existing compensators are fixed with bolts during use, and many are directly exposed to the external environment. Long-term exposure to wind and rain causes the bolts to corrode, affecting later disassembly and maintenance. To address these issues, the existing equipment needs to be improved.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figure 1-4 This utility model provides a technical solution: a corrosion-resistant corrugated sleeve complementary compensator, based on... Figure 1 , Figure 2 and Figure 4 As shown, one end of the inlet pipe 1 is detachably connected to one end of the bellows 3, and the other end of the bellows 3 is connected to one end of the drain pipe 5 via a connecting seal 4. A second positioning seat 6 is provided on the outer side of the middle of the drain pipe 5. A buffer spring 7 is sleeved between the connecting seal 4 and the second positioning seat 6 on the outer side of the drain pipe 5. The buffer spring 7 allows the bellows 3 to return to its original position after being stretched by fluid impact. A first positioning seat 2 is provided on the outer side of the connection between the inlet pipe 1 and the bellows 3. The bellows 3, the connecting seal 4, and the drain pipe 5 are located inside the protective cylinder 8. The sealing element 4 includes a sealing seat 401, which is located in the middle of the protective cylinder 8. A connecting pipe 402 is provided in the middle of the sealing seat 401. Both ends of the connecting pipe 402 are detachably connected to one end of the corrugated pipe 3 and the drain pipe 5, respectively. The connection between the corrugated pipe 3, the connecting pipe 402 and the drain pipe 5 and the sealing seat 401 is filled with sealing filler 403. At the same time, a sealing cap 404 is provided on the upper end of the sealing seat 401 outside the corrugated pipe 3. By connecting the sealing element 4, the connection between the corrugated pipe 3 and the drain pipe 5 has a high sealing performance and is not prone to leakage.

[0021] To further explain, the inlet pipe 1, the corrugated pipe 3, and the outlet pipe 5 are all coated with a nano-coating both inside and out, and the inlet pipe 1, the corrugated pipe 3, and the outlet pipe 5 are all made of metal, which further improves the service life of the inlet pipe 1, the corrugated pipe 3, and the outlet pipe 5 and avoids corrosion damage.

[0022] according to Figure 1 , Figure 2 and Figure 3 As shown, the protective cylinder 8 has symmetrical mounting flanges 9 at both ends. The inner middle of the two mounting flanges 9 is respectively engaged with the first positioning seat 2 and the second positioning seat 6. Limiting seats 11 and limiting cover plates 12 are respectively provided on both sides of the two mounting flanges 9.

At the same time, the two ends of the connecting rods 10 are magnetically connected to the first magnetic sleeve 1101 and the second magnetic sleeve 1201 respectively provided on the limiting seat 11 and the limiting cover plate 12. The two limiting cover plates 12 are respectively sleeved on the outer side of the liquid inlet pipe 1 and the liquid outlet pipe 5, and the two limiting cover plates 12 are slidably connected to the outer side of the liquid inlet pipe 1 and the liquid outlet pipe 5. Through the connecting rods 10, the corresponding first magnetic sleeve 1101 and the second magnetic sleeve 1201 are magnetically connected, so that the limiting seat 11 and the limiting cover plate 12 are connected to the mounting flanges 9, thereby limiting the connection between the liquid inlet pipe 1 and the liquid outlet pipe 5 and the protective cylinder 8, improving the protection of use.

[0023] To further explain, the protective cylinder 8 has a rectangular structure, and two symmetrical linear slide rails 801 are arranged on both sides inside the protective cylinder 8. The two linear slide rails 801 are respectively connected to the middle of the two sides of the sealing seat 401. By moving the linear slide rails 801, the sealing seat 401 moves with high stability and is not easy to deviate, thus improving its practicality. An inspection door 802 is installed in the middle of the front of the protective cylinder 8, and the position of the inspection door 802 corresponds to the position of the connecting sealing element 4. By opening the inspection door 802, it is convenient to inspect the connecting sealing element 4, thus improving its practicality.
