Description

Technical Field

[0001] This utility model relates to the field of corrugated compensator technology, and in particular to a novel anti-torsion direct-buried corrugated compensator. Background Technology

[0002] A corrugated compensator, also known as a corrugated joint or corrugated expansion joint, is a device used to absorb deformation caused by thermal expansion and contraction or other mechanical vibrations in a pipeline system. In some underground pipeline facilities, it is necessary to protect the pipeline from stress and deformation caused by thermal expansion and contraction, ground settlement, and other deformations. A direct-buried corrugated compensator is needed to protect pipelines buried underground.

[0003] In practical applications, existing direct-buried corrugated compensators often use simple gaskets for sealing. When connecting pipelines to the compensator via flanges, this sealing method is difficult to ensure the tightness of the connection. During long-term use, the gaskets are prone to aging and deformation due to fluctuations in pipeline medium pressure and changes in the external environment, leading to media leakage. To address these issues, a new type of anti-torsion direct-buried corrugated compensator is proposed. Utility Model Content

[0004] To overcome the above deficiencies, this utility model provides a novel anti-torsion direct-buried corrugated compensator, which aims to improve the problem in the prior art where the sealing gasket is prone to aging and deformation, leading to media leakage and greatly affecting the sealing and integrity of media transmission in the pipeline system.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0027] Reference Figures 1 to 2 This utility model provides one embodiment: a novel anti-torsion direct-buried corrugated compensator, including an outer sleeve 1, which serves as the external protective structure for the entire compensator, protecting the internal components from physical damage by the external environment, while also helping to maintain the stability of the overall structure and withstand certain external pressures. A corrugated pipe 2 is fixedly connected inside the outer sleeve 1, which is a key component for compensating for pipeline thermal expansion and contraction displacement. It has a stretchable corrugated structure that can absorb axial, lateral, or angular displacements caused by temperature changes in the pipeline through its own deformation, ensuring the normal operation of the pipeline system and preventing pipeline damage due to displacement.

[0028] The outer sleeve 1 is externally fixedly connected to a flange ring 3, which is used to connect with other pipeline components or equipment, providing an interface for the connection between the compensator and the pipeline system, ensuring the strength and stability of the connection, and facilitating the installation and disassembly of the compensator. The flange ring 3 is internally detachably connected to a sealing ring 4, which serves a sealing function to prevent media leakage from the flange connection, ensuring the airtightness of media transmission within the pipeline system, and avoiding problems such as media loss or environmental pollution due to leakage.

[0029] Flange ring 13 is externally detachably connected to flange ring 25, which works in conjunction with flange ring 13 to connect the compensator to other piping components, further enhancing the stability of the connection and ensuring its reliability under different operating conditions. Internally, flange ring 25 is internally detachably connected to sealing ring 26, which works in conjunction with sealing ring 14 to strengthen the sealing effect, improve the sealing performance at the connection, and prevent media leakage.

[0030] The sealing collar 4 is detachably connected to a connecting semicircular plate 7. The internal receiving groove 9 of this plate 7 mates with the outer surfaces of the sealing collar 4 and the second sealing collar 6, providing auxiliary sealing and enhancing connection stability, while also distributing stress at the connection point to some extent. The sealing collar 4 is also detachably connected to a connecting semicircular plate 8, which functions similarly to the connecting semicircular plate 7. Together, they act on the outside of the sealing collar 4, using the receiving groove 9 to enhance the sealing and connection effect and distribute stress at the connection point.

[0031] The sealing collar 26 is externally equipped with a fixing component, which includes multiple bolts 12 for passing through the flange ring 13, sealing collar 4, and related components. These bolts, in conjunction with nuts 13, tightly secure the components together, ensuring a robust connection and preventing loosening during operation of the compensator. The external threads of the bolts 12 connect to the interior of the flange ring 13 and sealing collar 4. Two nuts 13 are also connected to these external threads. Tightening the nuts 13 generates a tightening force, tightly connecting the flange ring 13, sealing collar 4, and other components, ensuring the stability and sealing of the connection.

[0032] Both the connecting semicircular plate 7 and the connecting semicircular plate 8 have internal receiving grooves 9 to accommodate the external parts of the sealing rings 4 and 6, allowing for better fit between the connecting semicircular plates and the sealing rings, thus enhancing the sealing and connection effect. Both the connecting semicircular plates 7 and 8 have external grooves 10 to provide a location for the installation of the elastic ring 11, facilitating its function and further improving the sealing performance. The external parts of the sealing rings 4 and 6 are in contact with the inner wall of the receiving grooves 9. An elastic ring 11 is detachably connected to the outside of the groove 10, using its own elasticity to generate pressure, compressing the connection between the sealing ring and the connecting semicircular plate, enhancing the sealing effect and preventing media leakage from the connection.

[0033] Reference Figures 3 to 4The bellows 2 is internally equipped with an anti-torsion component, which includes an inner sleeve 17. This component provides internal support for the bellows 2, enhancing its structural strength and acting as a guide to direct the flow of the medium within the pipe, reducing erosion and wear on the inner wall of the bellows 2. The inner sleeve 17 is externally and fixedly connected to one side of the inner wall of the bellows 2. Multiple base plates 14 are fixedly connected to both the left and right sides of the inner sleeve 1, providing a mounting base for the reinforcing rod 15. This allows the reinforcing rod 15 to be stably installed inside the outer sleeve 1 and also helps to enhance the stability of the internal structure of the outer sleeve 1.

[0034] Two base plates 14 are rotatably connected to adjacent sides with reinforcing rods 15. When the pipeline is subjected to torsional force, these rods, through their own rotation and contact with the outside of the bellows 2, disperse and offset the torsional force, protecting the bellows 2 from torsional damage and extending the service life of the compensator. Two auxiliary support plates 16 are fixedly connected to the outside of the base plates 14, enhancing the structural stability of the base plates 14 and thus improving the stability of the entire anti-torsion assembly. These support plates work in conjunction with the reinforcing rods 15 to disperse the torsional force, ensuring the reliability of the anti-torsion effect.

[0035] The outside of the reinforcing rod 15 is in contact with the outside of the bellows 2. The end of the bellows 2 away from the flange ring 3 is fixedly connected to the end pipe 18, which is used to connect with other pipe components to form a complete pipe system, ensuring the continuity of the pipe system and enabling the medium to be smoothly transmitted throughout the system. The outside of the end pipe 18 is in contact with the inner wall of the bellows 2.

[0036] Working principle: Before installation and use, ensure that all components are undamaged, clean, and free of impurities, oil, or other substances that may affect the connection and sealing performance. First, process the sealing-related components. Install sealing ring 1-4 inside flange ring 1-3, and sealing ring 2-6 inside flange ring 2-5. Connecting semicircular plate 1-7 and connecting semicircular plate 2-8 are installed outside sealing ring 1-4. Their internal receiving grooves 9 are used to fit the outside of sealing ring 1-4 and sealing ring 2-6 to further seal and connect. At the same time, install elastic rings 11 in the grooves 10 opened on the outside of connecting semicircular plate 1-7 and connecting semicircular plate 2-8. Elastic rings 11 can provide a certain elastic pressure to enhance the sealing effect and prevent media leakage.

[0037] The flange ring 25 is connected to the flange ring 3, which has the sealing sleeve 4 and related components installed. Multiple bolts 12 are used to pass through the flange ring 3, sealing sleeve 4 and flange ring 25 in sequence. Two nuts 13 are threaded on the outside of the bolts 12. By tightening the nuts 13, the flange ring 3 and flange ring 25 are tightly connected together, realizing the reliable connection of the compensator with other pipeline components, while ensuring the sealing of the connection. Inside the bellows 2, the inner sleeve 17 is fixedly connected to one side of the inner wall of the bellows 2, which plays a supporting and guiding role. Multiple base plates 14 are fixedly connected to the left and right sides inside the outer sleeve 1. Two base plates 14 are rotatably connected to the side of the two base plates 14 that are close to each other. Two auxiliary support plates 16 are fixedly connected to the outside of the base plates 14 to enhance the structural stability.

[0038] When the compensator is subjected to torsional force, the reinforcing rod 15 will contact the outside of the bellows 2. Through its own rotation and structural characteristics, it will disperse and cancel the torsional force, preventing the bellows 2 from being damaged due to excessive torsion. When the pipeline is torsion due to ground settlement or other external forces, the reinforcing rod 15 will rotate and be subjected to force according to the direction and degree of torsion. The auxiliary support plate 16 will also work together to ensure the stable operation of the entire anti-torsion assembly. The end of the bellows 2 away from the flange ring 3 is fixedly connected to the end pipe 18. The outside of the end pipe 18 is in contact with the inner wall of the bellows 2. The end pipe 18 is used to connect with other pipeline components to form a complete pipeline system.

[0039] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
