Description

Technical Field

[0001] This utility model relates to the field of compensator technology, and in particular to a composite damping bellows compensator. Background Technology

[0002] A bellows compensator is a compensating element that utilizes the elastic deformation characteristics of a bellows. Through the effective expansion and contraction deformation of the bellows, it can absorb dimensional changes in pipelines, conduits, and containers caused by thermal expansion and contraction, and at the same time compensate for the displacement of pipelines, conduits, and containers.

[0003] A Chinese patent with announcement number CN216590534U discloses a compound integrated vibration damping bellows compensator. The key technical features are: it includes a bellows compensator body; a first connecting pipe is provided on the upper side of the bellows compensator body; a connecting ring is fixedly installed on the upper side of the first connecting pipe; a first bellows is fixedly installed on the lower side of the first connecting pipe; a second connecting pipe is fixedly installed on the lower side of the first bellows; an upper flange is sleeved on the outer wall of the second connecting pipe; a second bellows is fixedly installed on the lower side of the second connecting pipe; a third connecting pipe is fixedly installed on the lower side of the second bellows; a fourth connecting pipe is fixedly installed on the lower side of the third bellows; and a fourth bellows is fixedly installed on the lower side of the fourth connecting pipe. The overall device structure is simple, and the vibration damping effect is better through the interlocking of several bellows, thus extending the overall service life and improving stability and practicality.

[0004] Existing technologies often have the following drawbacks: In existing composite damping bellows compensators, when pipelines, conduits, or containers undergo dimensional changes due to thermal expansion and contraction, the stability of their angular deformation is improved by setting connecting plates. However, the presence of connecting plates often affects the lateral deformation of the bellows compensator, thus hindering its compensation effect.

[0005] Therefore, this utility model provides a composite damping bellows compensator. Utility Model Content

[0006] The purpose of this invention is to address the shortcomings of existing technologies where the connecting plate affects the lateral deformation of the bellows compensator, thus impacting the compensating effect. A composite damping bellows compensator is proposed to address these shortcomings.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: a compound integrated shock-absorbing bellows compensator, comprising a first connecting pipe, one end of which is fixedly connected to a first bellows, the other end of which is fixedly connected to a second connecting pipe, the other end of which is fixedly connected to a second bellows, and the other end of which is fixedly connected to a third connecting pipe; a first connecting plate is mounted on the side of the first connecting pipe, and a second connecting plate is mounted on the side of the third connecting pipe; a third connecting plate is rotatably connected to the upper surface of the first connecting plate, and a fourth connecting plate is rotatably connected to the upper surface of the second connecting plate; a sliding rod is mounted on the side of the third connecting plate near the fourth connecting plate, and a sleeve rod is mounted on the side of the fourth connecting plate near the third connecting plate; the sleeve rod is sleeved on the surface of the sliding rod.

[0008] The effect achieved by the above components is that by setting the third connecting plate, the fourth connecting plate, the sleeve rod and the slide rod, the stability of the bellows compensator's angular deformation can be guaranteed as much as possible while avoiding affecting the lateral deformation of the bellows.

[0009] Preferably, two first clamping plates are fixedly connected to the side of the third connecting plate near the fourth connecting plate, and a first rotating plate is rotatably connected to the side of the two first clamping plates that are close to each other.

[0010] The effect achieved by the above components is that by setting the first clamping plate, the first rotating plate can be connected to the third connecting plate, and the first rotating plate, which is rotatably connected to the first clamping plate, can rotate.

[0011] Preferably, two second clamping plates are fixedly connected to the side of the fourth connecting plate near the third connecting plate, and a second rotating plate is rotatably connected to the side of the two second clamping plates that are close to each other.

[0012] The effect achieved by the above components is that by setting the second clamping plate, the second rotating plate can be connected to the fourth connecting plate, and the second rotating plate, which is rotatably connected to the second clamping plate, can rotate.

[0013] Preferably, a first rectangular block is fixedly connected to the side of the first rotating plate away from the third connecting plate, and a first rotating ball is rotatably connected to the inner wall of the first rectangular block, and the first rotating ball is fixedly connected to the slide rod.

[0014] The above components achieve the following effects: by setting the first rectangular block, the slide bar can be connected to the third connecting plate; by setting the first rotating ball, the stability of the slide bar's movement can be improved.

[0015] Preferably, a second rectangular block is fixedly connected to the side of the second rotating plate away from the fourth connecting plate, and a second rotating ball is rotatably connected to the inner wall of the second rectangular block, and the second rotating ball is fixedly connected to the sleeve rod.

[0016] The above components achieve the following effects: by setting the second rectangular block, the sleeve rod can be connected to the fourth connecting plate; by setting the second rotating ball, the stability of the sleeve rod movement can be improved.

[0017] Preferably, the sides of the first connecting pipe and the third connecting pipe are fixedly connected with a U-shaped plate, and the two U-shaped plates are respectively sleeved on the surfaces of the first connecting plate and the second connecting plate. The inner walls of the two U-shaped plates are slidably connected with limit rods.

[0018] The aforementioned components achieve the following effect: by setting the U-shaped plate and the limiting rod, the first connecting plate and the second connecting plate can be easily installed and disassembled, thereby facilitating the recycling of the bellows compensator when it is damaged.

[0019] Preferably, a pull plate is fixedly connected to the end of the limiting rod away from the molded plate, and a spring is sleeved on the surface of the limiting rod, with the two ends of the spring fixedly connected to the molded plate and the pull plate respectively.

[0020] The above components achieve the following effects: by setting up the pull plate, the spring can be easily installed; by setting up the spring, the position of the limit rod can be restricted.

[0021] In summary:

[0022] In this invention, by setting a third connecting plate and a fourth connecting plate, the sliding rod and the sleeve rod can be connected to the first connecting pipe and the third connecting pipe respectively. By setting the sliding rod and the sleeve rod, the first connecting plate and the second connecting plate can move closer or further apart, thereby maximizing the effect of lateral deformation of the bellows compensator. By setting a first clamping plate, a first rotating plate, a second clamping plate, a second rotating plate, as well as a first rotating bead and a second rotating bead, the first connecting plate and the second connecting plate can better adapt to the angular deformation of the bellows compensator, while maximizing the smoothness of the sliding rod sliding on the inner wall of the sleeve rod. By setting a return plate and a limiting rod, the first connecting plate and the second connecting plate can be easily recycled and reused, reducing the replacement cost of the bellows compensator.

[0029] Reference Figure 1 As shown, this utility model provides a technical solution: a compound integrated shock-absorbing bellows compensator, including a first connecting pipe 1, one end of which is fixedly connected to a first bellows 4, the other end of which is fixedly connected to a second connecting pipe 2, the other end of which is fixedly connected to a second bellows 5, and the other end of which is fixedly connected to a third connecting pipe 3. A first connecting plate 6 is installed on the side of the first connecting pipe 1, and a second connecting plate 7 is installed on the side of the third connecting pipe 3. A third connecting plate 8 is rotatably connected to the upper surface of the first connecting plate 6, and a fourth connecting plate 9 is rotatably connected to the upper surface of the second connecting plate 7. A sliding rod 17 is installed on the side of the third connecting plate 8 near the fourth connecting plate 9, and a sleeve rod 18 is installed on the side of the fourth connecting plate 9 near the third connecting plate 8. The sleeve rod 18 is sleeved on the surface of the sliding rod 17. By setting the third connecting plate 8, the fourth connecting plate 9, the sleeve rod 18, and the sliding rod 17, the stability of the bellows compensator's angular deformation can be ensured as much as possible while minimizing the impact on the lateral deformation of the bellows.

[0030] The following is a detailed explanation of its overall setup and function.

[0031] Reference Figures 1-5As shown in this embodiment: Two first clamping plates 10 are fixedly connected to the side of the third connecting plate 8 near the fourth connecting plate 9, and a first rotating plate 11 is rotatably connected to the side of the two first clamping plates 10 that are close to each other. By setting the first clamping plates 10, the first rotating plate 11 can be connected to the third connecting plate 8, and the first rotating plate 11 rotatably connected to the first clamping plates 10 can rotate. Two second clamping plates 13 are fixedly connected to the side of the fourth connecting plate 9 near the third connecting plate 8, and a second rotating plate 14 is rotatably connected to the side of the two second clamping plates 13 that are close to each other. By setting the second clamping plates 13, the second rotating plate 14 can be connected to the fourth connecting plate 9, and the second rotating plate 14 rotatably connected to the second clamping plates 13 can rotate. A first rectangular block 12 is fixedly connected to the side of the first rotating plate 11 away from the third connecting plate 8, and a first rotating bead 16 is rotatably connected to the inner wall of the first rectangular block 12. The first rotating bead 16 is fixedly connected to the sliding rod 17. By setting the first rectangular block 12, the slide bar 17 can be connected to the third connecting plate 8. By setting the first rotating bead 16, the stability of the slide bar 17 movement can be improved.

[0032] A second rectangular block 15 is fixedly connected to the side of the second rotating plate 14 away from the fourth connecting plate 9. A second rotating bead 19 is rotatably connected to the inner wall of the second rectangular block 15, and the second rotating bead 19 is fixedly connected to the sleeve rod 18. By setting the second rectangular block 15, the sleeve rod 18 can be connected to the fourth connecting plate 9, and by setting the second rotating bead 19, the stability of the movement of the sleeve rod 18 can be improved. A U-shaped plate 20 is fixedly connected to the sides of both the first connecting pipe 1 and the third connecting pipe 3. The two U-shaped plates 20 are respectively sleeved on the surfaces of the first connecting plate 6 and the second connecting plate 7, and the inner walls of both U-shaped plates 20 are slidably connected to limit rods 21. By setting the U-shaped plates 20 and the limit rods 21, the first connecting plate 6 and the second connecting plate 7 can be easily installed and disassembled, thus facilitating the recycling of the bellows compensator when it is damaged. A pull plate 22 is fixedly connected to the end of the limiting rod 21 away from the molded plate 20. A spring 23 is sleeved on the surface of the limiting rod 21, and the two ends of the spring 23 are fixedly connected to the molded plate 20 and the pull plate 22, respectively. By setting the pull plate 22, the spring 23 can be easily installed, and by setting the spring 23, the position of the limiting rod 21 can be restricted.

[0033] Working principle: When installing the first connecting plate 6 and the second connecting plate 7, pulling the pull plate 22 on the first connecting pipe 1 and the third connecting pipe 3 causes the limiting rod 21 to slide on the inner wall of the molded plate 20, so that the pull plate 22 moves away from the molded plate 20. Then, the first connecting plate 6 and the second connecting plate 7 are moved closer to the molded plate 20. When the pull plate 22 is released, under the action of the spring 23, the limiting rod 21 moves closer to the first connecting plate 6 and the third connecting plate 8, restricting the position of the first connecting plate 6 and the third connecting plate 8, thus completing the installation of the first connecting plate 6 and the third connecting plate 8. When the first corrugated pipe 4 and the second corrugated pipe 5 undergo lateral deformation, the first connecting plate 6 and the second connecting plate 7 respectively drive the third connecting plate 8 and the fourth connecting plate 9 to move closer or further away from each other. At this time, the first rotating plate 11 and the second rotating plate 14 rotate on the surfaces of the first clamping plate 10 and the second clamping plate 13 respectively, while the first rotating ball... 16 and the second rotating bead 19 rotate on the inner walls of the first rectangular block 12 and the second rectangular block 15 respectively, causing the slide rod 17 and the sleeve rod 18 to move closer to or away from the second connecting pipe 2. The slide rod 17 slides on the inner wall of the sleeve rod 18. By setting the third connecting plate 8 and the fourth connecting plate 9, the slide rod 17 and the sleeve rod 18 can be connected to the first connecting pipe 1 and the third connecting pipe 3 respectively. By setting the slide rod 17 and the sleeve rod 18, the first connecting plate 6 and the second connecting plate 7 can move closer to or away from each other, thereby ensuring the effect of lateral deformation of the bellows compensator as much as possible. By setting the first clamping plate 10, the first rotating plate 11, the second clamping plate 13, the second rotating plate 14, and the first rotating bead 16 and the second rotating bead 19, the first connecting plate 6 and the second connecting plate 7 can better adapt to the angular deformation of the bellows compensator, while ensuring the smoothness of the slide rod 17 sliding on the inner wall of the sleeve rod 18 as much as possible.
