Description

Technical Field

[0001] The utility model relates to the technical field of compensators, in particular to an impact-resistant metal bellows compensator. Background Art

[0002] In modern industry, pipeline systems are widely used to transport various fluid media. However, due to factors such as temperature changes, equipment vibrations, and pipeline installation errors, pipelines will have problems such as thermal expansion and contraction, displacement, and vibration. To compensate for these deformations, bellows compensators came into being.

[0003] In the prior art, once a failure occurs in the actual application of the bellows compensator, the repair and replacement work is usually relatively complicated. During the repair, the pipeline media at both ends of the bellows compensator are lost due to untimely plugging, resulting in economic losses. Summary of the Invention

[0004] In view of this, the purpose of the present utility model is to propose an impact-resistant metal bellows compensator to solve the problem of pipeline media loss during the repair and replacement of the compensator.

[0005] Based on the above purpose, the present utility model provides an impact-resistant metal bellows compensator, including: a first flange and a fixed pipe fixedly installed at one end of the first flange. The end of the fixed pipe away from the first flange is fixedly connected to a second flange. A sealing support is fixedly installed inside the first flange on one side of the fixed pipe. A sealing disk is rotatably installed on the sealing support. A sliding groove is formed on one side of the sealing disk. A sliding pin is slidably installed on the sliding groove. The sliding pin is fixedly installed on a sliding push block. One side of the sliding push block is fixedly connected to a push rod, and the push rod is slidably connected to the second flange.

[0006] As an optional implementation manner, a slider support seat is fixedly connected to the side of the fixed pipe away from the second flange. The sliding push block is slidably connected to the slider support seat. A high-strength spring is fixedly connected to the end of the sliding push block away from the push rod, and the end of the high-strength spring away from the sliding push block is fixedly connected to the first flange.

[0007] As an optional implementation manner, a compensator fixing disk is fixedly connected to one side of the second flange through a fixing bolt, and the compensator fixing disk is in contact with the push rod. The compensator fixing disk is fixedly installed at both ends of the bellows.

[0008] As an optional implementation manner, a plurality of uniformly distributed adjusting rod fixing seats are fixedly installed on the compensator fixing disk, and an adjusting rod is slidably installed between the adjusting rod fixing seats.

[0009] As an alternative embodiment, fixing nuts are threadedly connected to both ends of the adjusting rod, and the fixing nuts are used for positioning the fixing plate of the compensator. An adjusting nut is threadedly connected to the side of the adjusting rod away from the fixing nut and is used for limiting the fixing plate of the compensator.

[0010] As an alternative embodiment, a plurality of uniformly distributed support seats are fixedly installed on the fixed pipe between the first flange and the second flange.

[0011] As an alternative embodiment, a length adjusting rod is fixedly installed between the support seats, and the length adjusting rod is used for positioning the distance between the fixed pipes.

[0012] Advantages of the present utility model:

[0013] In the present utility model, a high-strength spring applies a force to the sliding push block to make the sliding push block slide to one side, thereby pulling the sealing disc to rotate on the fixed pipe, completely closing the fixed pipe by the sealing disc, and completely closing the pipe connected to the first flange on one side of the fixed pipe. Operators do not need to perform complex manual plugging operations, reducing the work intensity and technical requirements, saving the time for preparatory work, thus accelerating the overall progress of replacing the compensator. At the same time, it prevents a large amount of liquid or gas in the pipe from flowing out, reducing economic losses, avoiding the leakage of the medium in the pipe during the replacement process, and preventing possible personal injuries and environmental pollution.

[0014] When the bellows compensator needs to be replaced, the length adjusting rod is installed on the support seats. By adjusting the length of the length adjusting rod, a supporting force is exerted on both ends of the bellows compensator by the fixed pipes. At the same time, the fixing nuts at both ends of the adjusting rod are tightened to make the bellows contract inward under the extrusion force. Under the supporting force of the length adjusting rod and the locking force of the fixing nuts, the overall length of the bellows compensator is less than the distance between the pipes installed at both ends, creating more external space for the disassembly operation, enabling tools and equipment to operate more freely, reducing the difficulty of inconvenient operation caused by narrow space, greatly shortening the disassembly time, and reducing the impact on production caused by maintenance shutdown.

[0022] In order to make the objectives, technical solutions and advantages of the present utility model more clear and understandable, the present utility model will be further described in detail below in conjunction with specific embodiments.

[0024] Such as Figures 1 - 4As shown in the figure, an impact-resistant metal bellows compensator includes: a first flange 1 and a fixed pipe 12 fixedly installed at one end of the first flange 1. The end of the fixed pipe 12 far from the first flange 1 is fixedly connected to a second flange 10. On one side of the fixed pipe 12 and inside the first flange 1, a sealing support 7 is fixedly installed. A sealing disc 2 is rotatably installed on the sealing support 7. A sliding groove 17 is formed on one side of the sealing disc 2. A sliding pin 16 is slidably installed on the sliding groove 17. The sliding pin 16 is fixedly installed on a sliding push block 8. One side of the sliding push block 8 is fixedly connected to a push rod 13. The push rod 13 is slidably connected to the second flange 10.

[0025] In this way, a high-strength spring 15 applies a force to the sliding push block 8 to make the sliding push block 8 slide to one side, thereby pulling the sealing disc 2 to rotate on the fixed pipe 12, making the sealing disc 2 completely seal the fixed pipe 12, and completely sealing the pipeline connected to the first flange 1 on one side of the fixed pipe 12. Operators do not need to perform complex manual plugging operations, reducing the work intensity and technical requirements, saving the time for preparatory work, thus accelerating the overall progress of replacing the compensator. At the same time, it prevents a large amount of liquid or gas in the pipeline from flowing out, reduces economic losses, avoids the leakage of the medium in the pipeline during the replacement process, and prevents possible personal injuries and environmental pollution.

[0026] As an optional implementation manner, as Figures 1 - 4 shown, a slider support seat 9 is fixedly connected to the side of the fixed pipe 12 far from the second flange 10. A sliding push block 8 is slidably connected to the slider support seat 9. One end of the sliding push block 8 far from the push rod 13 is fixedly connected to a high-strength spring 15. One end of the high-strength spring 15 far from the sliding push block 8 is fixedly connected to the first flange 1;

[0027] On one side of the second flange 10, a compensator fixing disc 4 is fixedly connected by a fixing bolt 6, and the compensator fixing disc 4 is in contact with the push rod 13. The compensator fixing disc 4 is fixedly installed at both ends of the bellows 5;

[0028] A number of uniformly distributed adjusting rod fixing seats 19 are fixedly installed on the compensator fixing disc 4. An adjusting rod 20 is slidably installed between the adjusting rod fixing seats 19;

[0029] Both ends of the adjusting rod 20 are threadedly connected with fixing nuts 18, and the fixing nuts 18 are used for positioning the compensator fixing disc 4. One side of the adjusting rod 20 far from the fixing nut 18 is threadedly connected with an adjusting nut 14, and is used for limiting the compensator fixing disc 4.

[0030] Thus, when installing the fixed pipes 12 at both ends of the compensator fixed disk 4, the compensator fixed disk 4 pushes the push rod 13 to push open the sealing disk 2, and the conveyed material in the pipeline flows out through the corrugated pipe 5. By adjusting the distance of the adjusting nut 14 on the adjusting rod 20, the intensity of the impact force on the compensator fixed disk 4 from the inside of the pipe is changed. A reasonable distance setting can make the stress distribution in the pipeline more uniform during operation, improve the compensation ability and stability of the compensator, reduce local stress concentration, and lower the risk of pipeline damage.

[0031] As an alternative implementation, as Figures 1 - 4 shown, a number of uniformly distributed support seats 11 are fixedly installed on the fixed pipe 12 between the first flange 1 and the second flange 10;

[0032] A length adjusting rod 3 is fixedly installed between the support seats 11, and the length adjusting rod 3 is used to position the distance between the fixed pipes 12.

[0033] Thus, when it is necessary to replace the corrugated pipe compensator, the length adjusting rod 3 is installed on the support seats 11. By adjusting the length of the length adjusting rod 3, the fixed pipes 12 provide a supporting force at both ends of the corrugated pipe compensator. At the same time, the fixing nuts 18 at both ends of the adjusting rod 20 are tightened so that the corrugated pipe 5 shrinks inward after being squeezed. Under the supporting force of the length adjusting rod 3 and the locking force of the fixing nuts 18, the overall length of the corrugated pipe compensator is less than the distance between the pipes installed at both ends, creating more external space for disassembly operations, enabling tools and equipment to operate more freely, reducing the difficulty of inconvenient operation caused by narrow space, greatly shortening the disassembly time, and reducing the impact of maintenance downtime on production.

[0034] In this embodiment, as Figures 1 - 4As shown in the figure, when installing the fixed pipes 12 at both ends of the compensator fixed disk 4, the compensator fixed disk 4 pushes the push rod 13 to push open the sealing disk 2, and the conveyed material in the pipeline flows out through the corrugated pipe 5. By adjusting the distance of the adjusting nut 14 on the adjusting rod 20, the intensity of the impact force on the compensator fixed disk 4 from the inside of the pipe can be changed. A reasonable distance setting can make the stress distribution in the pipeline more uniform during operation, improve the compensation ability and stability of the compensator, reduce local stress concentration, and lower the risk of pipeline damage. When it is necessary to replace the corrugated pipe compensator, install the length adjusting rod 3 on the support seat 11. By adjusting the length of the length adjusting rod 3, a supporting force is exerted on both ends of the corrugated pipe compensator by the fixed pipes 12. At the same time, tighten the fixing nuts 18 at both ends of the adjusting rod 20 to make the corrugated pipe 5 contract inward after being squeezed. Under the supporting force of the length adjusting rod 3 and the locking force of the fixing nuts 18, the overall length of the corrugated pipe compensator is less than the distance between the pipelines installed at both ends, creating more external space for disassembly operations, enabling tools and equipment to operate more freely, reducing the difficulty of inconvenient operation caused by narrow space, greatly shortening the disassembly time, and reducing the impact on production caused by maintenance shutdown. At the same time, the high-strength spring 15 exerts a force on the sliding block 8 to make the sliding block 8 slide to one side, thereby pulling the sealing disk 2 to rotate on the fixed pipe 12, completely closing the fixed pipe 12, and completely closing the pipeline connected to the first flange 1 on one side of the fixed pipe 12. The operator does not need to perform complex manual plugging operations, reducing the work intensity and technical requirements, saving the time for preparatory work, thus accelerating the overall progress of replacing the compensator. At the same time, it prevents a large amount of liquid or gas in the pipeline from flowing out, reducing economic losses, avoiding the leakage of the medium in the pipeline during the replacement process, and preventing possible personal injuries and environmental pollution.
