Abstract
Description
Technical Field
[0001] This utility model relates to the field of pipeline leak sealing technology, and in particular to a leak sealing device for thermal pipelines. Background Technology
[0002] In thermal energy transmission systems, thermal pipelines serve as crucial carriers for transporting high-temperature, high-pressure media (such as steam and hot water), and their safe and stable operation is paramount. However, due to the harsh environment of high temperature, high pressure, and corrosion from complex media, thermal pipelines inevitably suffer damage such as cracks and perforations on their surfaces. If this damage is not addressed promptly and effectively, it will lead to leakage of the thermal medium, resulting not only in energy waste and increased operating costs but also potentially causing serious safety accidents.
[0003] While leak sealing technology for thermal pipelines has made some progress, existing technologies still have many shortcomings. Traditional leak sealing methods, such as welding repair, not only require downtime, disrupting production continuity, but are also cumbersome, demanding high levels of operator skill, and may lead to stress concentration issues after repair, affecting the long-term reliability of the pipeline. Another common leak sealing method is clamp sealing, but this method often requires custom-made clamps based on the specific size of the crack, resulting in poor versatility. Furthermore, the installation and disassembly of these clamps are complex and time-consuming. In emergencies, such as sudden pipeline leaks, clamp sealing is difficult to respond quickly and cannot meet the need for rapid leak sealing. In addition, existing leak sealing components often use a fixed design, unable to be flexibly adjusted according to the specific shape and size of the crack. If the leak sealing component does not match the crack, it will severely affect the sealing effect and may even lead to leak sealing failure.
[0004] Therefore, this application provides a device for sealing leaks in thermal pipelines to solve the above-mentioned technical problems. Utility Model Content
[0005] The technical problem to be solved by this utility model is to provide a thermal pipeline sealing device to solve the problem that existing sealing devices mostly adopt a bundled structure, which requires multiple bolt tightening operations and is cumbersome.
[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution:
[0007] A leak-sealing device for a thermal pipeline includes a positioning semi-ring. Two positioning seats are symmetrically fixed on the inner side of the positioning semi-ring. A vertical movable column is rotatably mounted on one end of the positioning semi-ring. A support frame is rotatably mounted on the top end of the movable column. The support frame extends directly above the opening of the positioning semi-ring. A stud is threaded into the top end of the support frame. The lower end of the stud protrudes from the lower end face of the support frame and is rotatably mounted on a base plate. A leak-sealing plate for adapting to cracks in the thermal pipeline is detachably mounted on the lower end of the base plate.
[0008] Optionally, each of the two positioning seats has a slot at its top, and a rubber pad is fixedly engaged in the slot.
[0009] Optionally, a T-shaped protrusion is fixed in the middle of the lower end face of the substrate, and a T-shaped groove is provided on the top of the plugging piece, wherein the T-shaped groove and the T-shaped protrusion are horizontally slidably inserted into each other.
[0010] Optionally, a sealing gasket is fixed to the lower end face of the plugging piece.
[0011] Optionally, the top of the stud extends beyond the upper surface of the support frame and is symmetrically fixed with two levers.
[0012] Optionally, the top of the support frame is fixed with a threaded cylinder through which the stud thread passes.
[0013] Optionally, a fastening nut is fitted onto the stud, and the fastening nut is located outside the top of the threaded cylinder.

[0015] In the above solution, the tight fit between the sealing gasket and the plugging plate effectively prevents leakage of the thermal medium, resulting in a good leak-sealing effect. Furthermore, the detachable design of the plugging plate allows for quick replacement based on the crack condition, offering flexibility in use. Additionally, the locking stud is secured with a tightening nut to prevent loosening and ensure a long-lasting leak-sealing effect.

[0029] like Figure 1-4 As shown, an embodiment of this utility model provides a leak-sealing device for thermal pipelines, including key components such as a positioning semi-ring 1, a movable column 2, a support frame 3, a stud 5, a base plate 501, and a leak-sealing plate 6. The specific implementation method is as follows:
[0030] The positioning half-ring 1 is the basic component of this device. Two positioning seats 101 are symmetrically fixed on the inner side of the positioning half-ring 1 for initial positioning and fitting against the surface of the heat pipe. A slot is opened at the top of the positioning seat 101 to engage and fix a rubber pad 102. The two positioning seats 101 allow the positioning half-ring 1 to be adapted to more pipe specifications, and the rubber pad 102 can prevent wear on the pipe, thus ensuring pipe safety.
[0031] The positioning semi-ring 1 has a vertical movable column 2 rotatably mounted at one end, and a support frame 3 rotatably mounted at the top of the movable column 2. The support frame 3 extends directly above the opening of the positioning semi-ring 1, allowing it to be easily moved to the side above the opening of the positioning semi-ring 1 during use. This facilitates the quick fitting of the positioning semi-ring 1 to the heat pipe, and then the support frame 3 can be moved to the side of the heat pipe away from the positioning semi-ring 1. This allows for adjustment of the position of the leak-sealing piece 6 to align with the crack for leak sealing.
[0032] In specific implementation, a stud 5 is threaded into the top of the support frame 3, and the lower end of the stud 5 protrudes from the lower end face of the support frame 3, and a base plate 501 is rotatably mounted thereon. A leak-stopping plate 6 for adapting to cracks in the thermal pipeline is detachably mounted on the lower end of the base plate 501. The contact pressure between the leak-stopping plate 6 and the pipeline crack can be adjusted by rotating the stud 5. In this embodiment, the leak-stopping plate 6 and the sealing gasket 7 are as follows: The top of the leak-stopping plate 6 has a T-shaped groove 601, which slides horizontally into the T-shaped protrusion 502 on the lower end face of the base plate 501, facilitating quick replacement of the leak-stopping plate 6. A sealing gasket 7 is fixed to the lower end face of the leak-stopping plate 6 to enhance the leak-stopping effect.
[0033] In addition, in this embodiment, the top of the stud 5 extends beyond the upper surface of the support frame 3, and two levers 503 are symmetrically fixed thereon for easy manual rotation of the stud 5. A threaded cylinder 4 is fixed at the top of the support frame 3 for the threaded stud 5 to pass through, ensuring stable rotation of the stud 5. A fastening nut 504 is fitted on the stud 5, located outside the top of the threaded cylinder 4, for locking the stud 5 and preventing loosening.
[0034] The working principle of this utility model is as follows: the thermal pipeline leak-sealing device utilizes a positioning semi-ring 1 to fit against the thermal pipeline. Then, through the cooperation of the movable column 2 and the support frame 3, the leak-sealing piece 6 is quickly positioned above the crack. The rotating and pressing action of the stud 5 ensures that the leak-sealing piece 6 tightly adheres to the pipeline crack, achieving efficient leak sealing in conjunction with the sealing gasket 7. Simultaneously, the leak-sealing piece 6, through the insertion and engagement of the T-shaped protrusion 502 and the T-shaped groove 601, can be quickly replaced to adapt to different cracks, further improving the leak-sealing effect.
[0035] In summary, this device effectively prevents the leakage of thermal media through the tight fit between the sealing gasket 7 and the plugging plate 6, resulting in a good leak-sealing effect. Furthermore, thanks to the detachable design of the plugging plate 6, it can be quickly replaced according to the crack condition, offering flexibility in use. In addition, the locking stud 5 is secured with the fastening nut 504 to prevent loosening and ensure a long-lasting leak-sealing effect. This utility model features a compact design, simple operation, rapid leak location and sealing, and can flexibly adapt to different specifications of thermal pipes and cracks, resulting in excellent overall performance.

Furthermore, to avoid unnecessary confusion regarding the essence of this utility model, well-known methods, processes, procedures, components, and circuits are not described in detail.
[0037] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
