Description

Technical Field

[0001] This utility model relates to the technical field of metal corrugated compensators, specifically to a metal corrugated compensator with adaptive adjustment function. Background Technology

[0002] In industries such as petroleum, chemical, power, and heating, pipeline systems often experience thermal expansion and contraction, and displacement deviations due to factors such as changes in medium temperature, fluctuations in external ambient temperature, and equipment vibration during operation. If these displacements cannot be effectively compensated, they can lead to enormous stress inside the pipeline, resulting in serious problems such as pipeline cracking, joint leaks, and even equipment damage. Therefore, metal bellows compensators, as a key component capable of absorbing pipeline displacement and alleviating pipeline stress, are widely used in various pipeline systems.

[0003] Currently, most commercially available metal bellows compensators consist of a basic structure including a bellows and connecting pipes (top and bottom pipes), relying on the elastic deformation of the bellows to achieve displacement compensation. However, traditional metal bellows compensators have significant limitations in practical applications: Firstly, the connection structure of traditional compensators is mostly a fixed design, unable to be flexibly adjusted according to the actual displacement of the pipeline and installation requirements. When there is a large displacement deviation in the pipeline or a slight error in the installation position, the compensator is difficult to fit precisely, which not only reduces the compensation effect but may also cause additional stress on the bellows due to forced installation, shortening its service life. Secondly, traditional compensators lack reliable positioning and locking mechanisms. During long-term operation, the connection parts are prone to loosening due to factors such as medium pressure and vibration, leading to a decrease in the stability of the connection between the compensator and the pipeline and increasing the risk of leakage. Utility Model Content

[0004] Technical problems to be solved

[0005] In view of the above-mentioned shortcomings of the existing technology, the present invention provides a metal corrugation compensator with adaptive adjustment function, which can effectively solve the problems in the existing technology.

[0006] Technical solution

[0007] This utility model provides a metal corrugated compensator with adaptive adjustment function, including: a top tube and a bottom tube, the bottom tube and the top tube being connected and fixed by a corrugated tube, a positioning ring being fixed on the outer side of the top tube, a positioning hole being opened on the outer side of the positioning ring, and a compensation structure being fixed on the outer side of the bottom tube, the compensation structure including two sets of side plates, a connecting block disposed in the side plates and a screw disposed in the connecting block, the end of the screw being disposed in the positioning ring.

[0008] Furthermore, a locking nut is fitted and fixed on the outside of the positioning hole of the screw.

[0009] Furthermore, the side plate has symmetrical grooves on the outside of the bottom tube, and the two sets of connecting blocks are engaged in the grooves.

[0010] Furthermore, a threaded hole is provided in the middle of the connecting block, the screw engages in the threaded hole, and a mating nut is sleeved and fixed on this side.

[0011] Furthermore, the two side panels are grouped together, and both side panels have an L-shaped structure.

[0012] Beneficial effects

[0013] In this invention, the metal corrugated compensator features a compensation structure comprising a side plate, a connecting block, and a screw on the outer side of the bottom pipe. The end of the screw is positioned within a positioning ring on the outer side of the top pipe. Simultaneously, a threaded hole is formed in the center of the connecting block to engage with the screw. Rotating the screw moves the connecting block within the groove of the side plate, thereby adjusting the relative position between the top and bottom pipes and achieving adaptive adjustment of pipeline displacement. Compared to traditional fixed-structure compensators, this design more accurately matches the displacement of the pipeline caused by temperature changes or vibration, effectively alleviating pipeline stress, improving compensation performance, and extending the service life of both the pipeline and the compensator.

[0014] In this device, a locking nut is fitted and fixed to the outside of the positioning hole of the screw in the compensation structure. After the position adjustment is completed, the screw and the positioning ring can be firmly fixed by tightening the locking nut to prevent the screw from loosening due to vibration or other factors during operation. At the same time, the side plate has an L-shaped structure and is symmetrically arranged on the outside of the bottom pipe. The connecting block is stuck in the groove of the side plate. This structural design can limit the movement direction of the connecting block, ensure the stability of the adjustment process, further enhance the connection reliability between the top pipe and the bottom pipe, significantly reduce the risk of pipeline medium leakage, and improve the safety of industrial pipeline system operation.

[0021] The present invention will be further described below with reference to the embodiments.

[0022] Example: A metal corrugated compensator with adaptive adjustment function, see attached figure. Figure 1 - Appendix Figure 3 The system includes a jacking pipe 2 and a bottom pipe 1, which are connected and fixed by a corrugated pipe 3. A positioning ring 21 is fixed on the outside of the jacking pipe 2, and a positioning hole 22 is opened on the outside of the positioning ring 21. A compensation structure 4 is fixed on the outside of the bottom pipe 1. The compensation structure 4 includes two sets of side plates 41, a connecting block 42 set in the side plate 41, and a screw 43 set in the connecting block 42. The end of the screw 43 is set in the positioning ring 21. The metal corrugated compensator sets a compensation structure 4 including a side plate 41, a connecting block 42 and a screw 43 on the outside of the bottom pipe 1, and the end of the screw 43 is set in the positioning ring 21 on the outside of the jacking pipe 2. At the same time, a threaded hole that meshes with the screw 43 is opened in the middle of the connecting block 42. By rotating the screw 43, the connecting block 42 can be moved in the groove of the side plate 41, thereby adjusting the relative position between the jacking pipe 2 and the bottom pipe 1, and realizing adaptive adjustment of pipe displacement. Compared to traditional fixed-structure compensators, it can more accurately match the displacement of pipelines caused by temperature changes or vibrations, effectively relieve pipeline stress, improve compensation effect, and extend the service life of pipelines and compensators.

[0023] A locking nut 45 is fitted and fixed on the outside of the positioning hole 22 of the screw 43; in the compensation structure 4, a locking nut 45 is fitted and fixed on the outside of the positioning hole 22 of the screw 43. After the position adjustment is completed, the screw 43 and the positioning ring 21 can be firmly fixed by tightening the locking nut 45 to prevent the screw 43 from loosening due to vibration and other factors during operation; at the same time, the side plate 41 has an L-shaped structure and is symmetrically arranged on the outside of the bottom pipe 1. The connecting block 42 is stuck in the groove of the side plate 41. This structural design can limit the movement direction of the connecting block 42, ensure the stability of the adjustment process, further enhance the connection reliability between the top pipe 2 and the bottom pipe 1, significantly reduce the risk of pipeline medium leakage, and improve the safety of industrial pipeline system operation.

[0024] The side plates 41 have symmetrically formed grooves on the outer side of the bottom pipe 1, and two sets of connecting blocks 42 are fitted into these grooves. A threaded hole is formed in the middle of each connecting block 42, and a screw 43 engages within this threaded hole. A mating nut 44 is also fitted and fixed to this side. The side plates 41 are arranged in pairs, and both side plates 41 have an L-shaped structure. All components of the compensation structure 4 (side plates 41, connecting blocks 42, screws 43, locking nuts 45, and mating nuts 44) are modularly designed. The symmetrical arrangement and groove structure of the side plates 41 facilitate the installation and movement of the connecting blocks 42. The threaded engagement between the screws 43 and the connecting blocks 42 is simple to operate, requiring no complex tools for adjustment and fixation. Furthermore, the connections between the components are clear, making disassembly and assembly easy when maintenance or replacement is needed. This significantly reduces the difficulty of installation and maintenance, saves manpower and time costs, and meets the needs of efficient operation and maintenance of industrial pipeline systems.

[0025] By adjusting the rotation of screw 43, compensation for different displacements between the jacking pipe 2 and the bottom pipe 1 can be achieved, adapting to the displacement requirements of the pipeline under different working conditions. Whether it is a small-range displacement due to thermal expansion and contraction or a positional deviation caused by installation errors, it can be effectively adjusted through the compensation structure 4. At the same time, this structural design is not overly restricted by factors such as pipe diameter and medium type, and the dimensions of each component can be flexibly adjusted according to the actual pipeline specifications. It is suitable for industrial pipeline systems in multiple fields such as petroleum, chemical, power, and heating, and has broad application prospects.
