Description

Technical Field

[0001] The utility model relates to the technical field of bellows compensators, in particular to a bellows compensator with an adjustable structure. Background Art

[0002] The bellows compensator is an expansion joint made of a metal bellows. It can expand and contract along the axial direction and allows a small amount of bending. It is used on the pipeline for axial length compensation. In order to prevent the compensation amount from exceeding the allowable amount, protective pull rods or protective rings are provided at both ends of the bellows. It is generally used on pipelines with low temperature and pressure and short length.

[0003] In the prior art, the bellows compensator is connected to the external connection pipe through a flange. When the specifications and sizes of the flange do not match, it will cause certain inconveniences to the subsequent installation.

[0004] The existing patent (Announcement No.: CN220037823U) discloses a bellows compensator with an adjustable structure. The user aligns the center point of the docking plate with the center point of the external pipe flange to be fixed, and then tightens the first butterfly hand-tightening seat. The first butterfly hand-tightening seat drives the first threaded bolt to rotate together through the connecting rod. Since the first threaded bolt is engaged with the threaded groove, the rotation of the first threaded bolt drives the connecting rod to move downward together. Since the connecting rod is rotatably connected to the fixing plate through the through hole, the fixing plate slides tightly downward along the inner wall of the empty groove until the clamping pad on the inner side of the fixing plate abuts against the edge of the external flange. The three groups of fixing plates are adjusted in sequence so that they clamp and fix the flange, and then tighten the second butterfly hand-tightening seat. The second butterfly hand-tightening seat drives the second threaded bolt to rotate. Since the second threaded bolt is engaged with the threaded hole, the second threaded bolt drives the extrusion plate to move inward until the extrusion pad abuts against the surface of the external flange, further improving the fixing effect of the external flange.

[0005] In response to the above problems, although the solution provided by the existing patent can achieve a fixing effect when the bellows and the external flange are in contact through the cooperation of components such as the first butterfly-shaped hand-tightening seat, in actual use, multiple manual adjustments are required to achieve the tightening effect, and the operation is relatively cumbersome and troublesome. Summary of the invention

Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] The utility model provides a technical solution:

[0027] See also Figures 1 to 3A bellows compensator with an adjustable structure includes a compensating tube body 1, connecting plates 2 are fixed at both ends of the compensating tube body 1, and an adjusting mechanism 3 is arranged on one side of the outer wall of the compensating tube body 1; the adjusting mechanism 3 includes a threaded rod 302, two threaded rods 302 are respectively rotatably connected to the opposite outer walls of the two connecting plates 2, a rotating rod 301 is fixed to one end of the threaded rod 302 away from the connecting plate 2, a collar 303 is slidably connected to the outside of the threaded rod 302, a connecting block 304 is fixed to the top of the collar 303, and the connecting rod 301 is fixed to the outer side of the threaded rod 302. A connecting block 305 is fixed on the upper outer wall of the connecting block 304, and a slot 306 is provided at one end of the connecting block 305 away from the connecting block 304, and a sealing plate 307 is slidably connected inside the slot 306. The ring 303 is threadedly connected to the threaded rod 302, and a sliding structure is formed between the ring 303 and the threaded rod 302. A sleeve 4 is sleeved on the outside of the two rotating rods 301, and a threaded head 6 is fixed on one end of the rotating rod 301 that passes through the sleeve 4, and a connecting hole 5 is provided on the inner wall of the sleeve 4 at a position corresponding to the threaded head 6.

[0028] By adopting the above technical scheme, the compensation tube body 1 is first connected to the external flange through the connecting plate 2, and then the rotating rod 301 is manually twisted to make the threaded rod 302 rotate accordingly, so as to push the ring 303 to drive the connecting block 304 and the connecting block 305 to slide, and the blocking plate 307 slides along the slot 306 to avoid being limited and unable to move, until the connecting block 304 and the connecting block 305 are in contact with the connecting plate 2, and the blocking plate 307 slides and fits on one side of the flange, and then the rotating rod 301 is reversely twisted, so that the connecting plate 2 and the flange can be fixed, and the fixation is convenient and quick to avoid multiple operations being too troublesome. The threaded heads 6 fixed by the two rotating rods 301 are inserted into the sleeve 4 and are threadedly connected to the connecting hole 5, so that the positions of the two rotating rods 301 are adjusted by rotating the sleeve 4, so that after the length of the compensation tube body 1 to be adjusted is adjusted according to the needs, it contacts the connecting plate 2 to avoid resetting.

[0029] Specifically, Figure 1 and Figure 4As shown, a stabilizing mechanism 7 is provided on the other side of the outer wall of the compensation tube body 1, and the stabilizing mechanism 7 includes a first connecting rod 701, which is fixed on one side of the outer wall of the connecting plate 2, and a connecting tube 702 is sleeved on the end of the first connecting rod 701 away from the connecting plate 2, and a second connecting rod 703 is passed through one side of the first connecting rod 701 inside the connecting tube 702, and the stabilizing mechanism 7 also includes a sliding ring 704, which is slidably connected to the outer wall of the second connecting rod 703, and a reinforcing rod 705 is fixed between the sliding ring 704 and the sleeve ring 303, and a rubber scraper 706 is installed on the reinforcing rod 705 facing the outer wall of the compensation tube body 1, and the first connecting rod 701 passes through the interior of the connecting tube 702, and a sliding structure is formed between the first connecting rod 701 and the connecting tube 702, and the rubber scraper 706 forms a sliding structure with the compensation tube body 1 through the sliding ring 704, and the rubber scraper 706 fits tightly with the compensation tube body 1.

[0030] By adopting the above technical solution, when the length of the compensation tube body 1 and the connecting plate 2 is adjusted, the first connecting rod 701 and the second connecting rod 703 slide inside the connecting tube 702 to avoid distortion or dislocation of the compensation tube body 1. The ring 303 drives the reinforcement rod 705, and the two reinforcement rods 705 respectively drive the corresponding sliding ring 704 to slide along the first connecting rod 701 or the second connecting rod 703, thereby improving the stability of the sliding process of the ring 303 and avoiding rotation with the threaded rod 302. At the same time, the rubber scraper 706 follows the reinforcement rod 705 to scrape away dust from the compensation tube body 1. Each compensator is provided with two adjustment mechanisms 3 and two stabilization mechanisms 7 to form a symmetrical form to ensure the stability of the adjustment process.

[0031] Working principle: The compensating tube body 1 is connected to the external equipment through the connecting plate 2 and the flange. The threaded rod 302 is rotated by rotating the rotating rod 301, so that the collar 303 drives the connecting block 304 to slide toward the connecting plate 2 until the connecting block 305 fits the connecting plate 2, and the blocking plate 307 slides through the slot 306 and snaps on one side of the flange. Then, the rotating rod 301 is twisted in the opposite direction to reset the collar 303 so that the connecting plate 2 and the flange are fixed. The connecting hole 5 of the sleeve 4 is threadedly connected with the threaded heads 6 of the two rotating rods 301 to facilitate the adjustment of the length. The distance between the two connecting plates 2 can be adjusted according to the needs of the compensator. The length of the compensation tube body 1 can be adjusted. The other end of the reinforcement rod 705 fixed by the collar 303 is sleeved on the corresponding first connecting rod 701 or the second connecting rod 703 through the sliding ring 704 to prevent the collar 303 from rotating with the rotation of the threaded rod 302. When the reinforcement rod 705 moves with the collar 303, the rubber scraper 706 fits the compensation tube body 1 to scrape and absorb dust. At the same time, the first connecting rod 701 and the second connecting rod 703 passing through the inside of the connecting tube 702 form a telescopic rod and are connected inside the two connecting plates 2, and the length is adjusted according to the required length of the following adjustment mechanism 3 and the compensator.

[0032] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not make the essence of the corresponding technical solution deviate from the scope of the technical solution of the embodiments of the utility model.
