Description

Technical Field

[0001] This utility model relates to the field of compensator technology, specifically to a compensator with an elastic mechanism. Background Technology

[0002] In industrial production and various pipeline transportation systems, pipelines are prone to axial, lateral, or angular displacement due to factors such as changes in medium temperature, pressure fluctuations, and foundation settlement. If these displacements cannot be effectively compensated, excessive stress can occur at pipeline connections, leading to leaks, ruptures, and other safety accidents, seriously affecting the stable operation of the system and production safety. To solve this problem, compensators, as a key component capable of absorbing pipeline displacement, are widely used.

[0003] While traditional compensators can compensate for pipeline displacement to a certain extent, they have significant limitations in terms of elastic adjustment. Once the elastic components of most traditional compensators are installed, their elastic force remains fixed, making it difficult to flexibly adjust according to changes in actual working conditions. This results in low applicability and hinders the stable operation of pipeline systems under complex and variable conditions. Therefore, this invention proposes a compensator with an elastic mechanism to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide a compensator with an elastic mechanism to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a compensator with an elastic mechanism, comprising a bellows, with a first connecting pipe and a second connecting pipe fixedly connected to both ends of the bellows, a fixed ring plate fixed on the first connecting pipe, a plurality of elastic mechanisms being provided between the fixed ring plate and the second connecting pipe, and an adjustment mechanism for adjusting the elastic mechanism being provided on the fixed ring plate, the adjustment mechanism being able to push the elastic component in the elastic mechanism to achieve adjustment.

[0006] Preferably, the elastic mechanism includes a fixed block fixedly installed on the second connecting pipe, one end of the fixed block is fixedly connected to a sliding rod, a connecting spring serving as an elastic component is sleeved on the sliding rod, and the other end of the sliding rod slides through the fixed ring plate.

[0007] Preferably, the adjustment mechanism includes a connecting slide plate that slides through the fixed ring plate, one end of which is fixedly connected to a pushing slide plate, and the pushing slide plate is slidably connected to a sliding rod.

[0008] Preferably, a sliding insert plate is slidably connected to the fixed ring plate, a connecting plate is fixedly connected to the upper end of the sliding insert plate, and a return spring is sleeved on the sliding insert plate. One end of the return spring is connected to the connecting plate, and the other end of the return spring is connected to the fixed ring plate.

[0009] Preferably, the connecting slide plate has multiple positioning slots for the sliding insert plate to extend into. By cooperating with different positioning slots, the position of the connecting slide plate can be fixed, thereby fixing the pushing state of the connecting spring by the sliding slide plate.

At the same time, the setting of the adjustment mechanism solves the problem of fixed elastic force of traditional compensators. The connecting slide plate drives the sliding plate to slide along the sliding rod, which can flexibly adjust the extension and contraction of the connecting spring, thereby changing the elastic force to adapt to the pipe displacement requirements under different working conditions, making it highly applicable.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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 to 4This utility model provides a technical solution: a compensator with an elastic mechanism, including a bellows 2, which serves as the core displacement compensation component. The bellows 2 has a first connecting pipe 1 and a second connecting pipe 3 fixedly connected to its two ends by welding. A fixing ring plate 4 is welded and fixed to the first connecting pipe 1. Multiple sets of elastic mechanisms 6 are arranged between the fixing ring plate 4 and the second connecting pipe 3. The multiple sets of elastic mechanisms 6 are evenly distributed along the circumference of the bellows 2, which allows the compensator to experience more balanced force when subjected to displacement. The fixing ring plate 4 is provided with an adjustment mechanism 5 for adjusting the elastic mechanisms 6. The joint mechanism 5 can push the elastic component in the elastic mechanism 6 to adjust the elastic force, thereby adapting to the pipeline displacement requirements under different working conditions. Through the synergistic effect of the bellows 2 and multiple sets of elastic mechanisms 6, the stress at the pipeline connection is effectively reduced, ensuring the stable operation of the system. At the same time, the setting of the adjustment mechanism 5 solves the problem of fixed elastic force of traditional compensators. The connecting slide plate 52 drives the sliding slide plate 51 to slide along the sliding rod 61, which can flexibly adjust the extension and contraction of the connecting spring 62, thereby changing the elastic force to adapt to the pipeline displacement requirements under different working conditions, making it highly applicable.

[0020] like Figure 2 as well as Figure 3 As shown, the elastic mechanism 6 includes a fixed block 63 that is fixedly installed on the outer wall of the second connecting pipe 3 by welding. A sliding rod 61 is welded to one end of the fixed block 63. A connecting spring 62, which serves as an elastic component, is sleeved on the sliding rod 61. The other end of the sliding rod 61, away from the fixed block 63, slides through a sliding hole opened on the fixed ring plate 4.

[0021] like Figure 3 as well as Figure 4 As shown, the adjustment mechanism 5 includes a connecting slide plate 52 that slides through a guide hole on the fixed ring plate 4. The guide hole guides the sliding of the connecting slide plate 52. A push slide plate 51 is welded and fixed to one end of the connecting slide plate 52 near the elastic mechanism 6. The push slide plate 51 has a through hole that matches the sliding rod 61. The push slide plate 51 is slidably connected to the sliding rod 61 through the through hole to ensure the stability of the push slide plate 51 when it slides along the sliding rod 61.

[0022] like Figure 3 as well as Figure 4 As shown, a sliding insert plate 54 is slidably connected to the fixed ring plate 4 through a groove. The groove can limit and guide the sliding of the sliding insert plate 54. A connecting plate 56 is fixedly connected to the upper end of the sliding insert plate 54 by welding. A return spring 55 is sleeved on the sliding insert plate 54. One end of the return spring 55 is welded to the connecting plate 56, and the other end is welded to the upper surface of the fixed ring plate 4. The welding fixation can ensure that the connection between the two ends of the return spring 55 will not loosen when it is stretched or contracted under force.

[0023] like Figure 4As shown, the connecting slide plate 52 has multiple positioning slots 53 at the end facing the sliding insert plate 54, into which the sliding insert plate 54 extends. These positioning slots 53 are evenly distributed along the sliding direction of the connecting slide plate 52. Through the cooperation of the sliding insert plate 54 with the different positioning slots 53, the position of the connecting slide plate 52 can be precisely fixed, thereby fixing the pushing state of the sliding slide plate 51 on the connecting spring 62, ensuring stable and reliable elastic force after adjustment. Figure 2 As shown, one end of the connecting spring 62 is welded and fixed to the push slide plate 51, and the other end is welded and fixed to the fixing block 63. During the extension and retraction process, the connection is kept stable, and the elastic force is precisely adjusted.

[0024] In actual use, the push plate 51 of the adjusting mechanism 5 is located on the sliding rod 61 and connected to one end of the connecting spring 62. When the pipeline is displaced due to temperature changes, the first connecting pipe 1 and the second connecting pipe 3 move relative to each other, and the bellows 2 expands and contracts to compensate for the displacement. At the same time, the sliding rod 61 slides in the fixed ring plate 4, and the connecting spring 62 is stretched or compressed, which, together with the bellows 2, buffers the force brought by the displacement. If it is necessary to adjust the elastic force, the connecting plate 52 of the adjusting mechanism 5 can be moved to drive the push plate 51 to slide along the sliding rod 61, thereby changing the expansion and contraction of the connecting spring 62. During the adjustment process, the sliding insert plate 54 on the fixed ring plate 4 can be inserted into different positioning slots 53 on the connecting plate 52 under the action of the return spring 55. The position of the sliding insert plate 54 is fixed by the connecting plate 56, thereby fixing the position of the connecting plate 52 and the push plate 51, realizing the stable adjustment of the elastic force of the connecting spring 62, and ensuring that the compensator adapts to the pipeline displacement compensation needs under different working conditions.
