[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0019] Please see Figures 1-4In this embodiment of the present invention, a quick connection device for insulated pipes with a compensation structure includes two insulated pipes 1. A compensation mechanism is installed between the connecting flanges of the two insulated pipes 1 that are close to each other. The compensation mechanism includes a fixing component, a telescopic component, and a limiting component. An installation flange 3 is integrally formed at the ends of the fixing component and the telescopic component that are far apart from each other. The fixing component also includes a fixing pipe 2 welded to one end of one installation flange 3. A fixing plate 4 is welded to the outer periphery of the fixing pipe 2. The telescopic component also includes a telescopic pipe 5 welded to one end of the other installation flange 3. One end of the telescopic pipe 5 is inserted into the inner cavity of the fixing pipe 2. A clamping cavity 9 is formed between the inner periphery of the fixing pipe 2 and the outer periphery of the telescopic pipe 5.

[0020] In this embodiment: First, before installing the compensation mechanism to one end of the fixed insulation pipe 1 at the construction site, the compensation mechanism is first assembled in the factory, and then the assembled compensation mechanism is transported to the construction site. Then, the mounting flange 3 at one end of the fixed pipe 2 is connected to the connecting flange at one end of the fixed insulation pipe 1. After the connection, bolts and nuts are used to fix it. At this time, the fixed pipe 2 and the fixed insulation pipe 1 are connected. After the installation is completed, the other unfixed insulation pipe 1 is connected to the mounting flange 3 at one end of the telescopic pipe 5.

[0021] Please refer to this carefully. Figure 2 and Figure 3 The limiting component includes a connecting plate 6 sleeved on the outer periphery of the telescopic tube 5. A sealing ring 7 protruding outward is integrally formed at one end of the connecting plate 6 near the inner cavity of the fixed tube 2. The sealing ring 7 is inserted into one end of the inner cavity of the clamping cavity 9. The limiting component also includes a limiting ring 10 welded to the inner wall of the fixed tube 2 away from the telescopic tube 5. The limiting ring 10 has multiple through holes 11 circumferentially opened inside. The limiting component also includes a sliding ring 8 installed on the telescopic tube 5 at one end inside the fixed tube 2 by bolts. The clamping cavity 9 and the limiting ring 10 are used to limit the maximum displacement distance of the sliding ring 8.

[0022] In this embodiment: When assembling the compensation mechanism in the factory, firstly, the connecting plate 6 and the sealing ring 7 are fitted onto the outer wall of the telescopic tube 5. Then, one end of the telescopic tube 5 is inserted into the inner wall of the fixed tube 2 until one end of the telescopic tube 5 passes through the fixed tube 2 and extends to the outside of the telescopic block 5. Then, the sliding ring 8 is connected to one end of the telescopic tube 5. Then, a bolt is passed through the round hole inside the sliding ring 8 and threadedly connected to the threaded hole inside the telescopic tube 5 until the bolt is fully tightened. Then, the telescopic tube 5 is pulled again, and the telescopic tube 5 slides into the inner cavity of the fixed tube 2. Then, the limiting ring 10 is welded to one end of the inner wall of the fixed tube 2.

[0023] Before welding the limiting ring 10 and after the sliding ring 8 is fixed, the connecting plate 6 is pushed, and the connecting plate 6 drives the sealing ring 7 to be inserted into the clamping cavity 9. Then, the connecting plate 6 and the fixing plate 4 are connected with bolts and nuts. At this time, the sealing ring 7 limits the front end of the sliding ring 8, and the welded limiting ring 10 limits the rear end of the sliding ring 8.

[0024] The compensation mechanism assembled in this way achieves internal sliding limit, eliminating the need for external structural limit. Therefore, during assembly, no external limit adjustment is required; only the installation position needs to be adjusted, thus improving on-site installation efficiency.

[0025] After the compensation mechanism is connected to the insulation pipe 1, and during the use of the insulation pipe 1, the telescopic pipe 5 slides relative to the fixed pipe 2 during the thermal expansion and contraction process. When the sliding ring 8 slides towards the limiting ring 10, some high-temperature steam moves through the through hole 11, which can reduce resistance.

[0026] Please refer to this carefully. Figure 3 A sealing ring is installed at the contact position between the clamping cavity 9 and the fixed tube 2 and the telescopic tube 5, and a sealing ring is installed between the outer circumference of the sliding ring 8 and the inner circumference of the fixed tube 2.

[0027] In this embodiment: the above design can effectively ensure the sealing performance of the connection and avoid the problem of poor sealing.

[0028] Please refer to this carefully. Figure 2 , Figure 3 The fixing plate 4 and the connecting plate 6 are fixedly connected by bolts and nuts, and the connecting flange and the mounting flange 3 are fixedly connected by bolts and nuts.

[0029] In this embodiment, the sealing ring 7 can be installed quickly using this method.

[0030] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
