Description

Technical Field

[0001] The utility model relates to the technical field of pipelines, in particular to a pipeline for a heating and cooling system. Background Art

[0002] Pipes used in heating and cooling systems are typically made from various steel alloys to adapt to diverse environmental conditions and transmission requirements. These pipes must not only withstand extreme high and low temperatures but also possess sufficient corrosion resistance and thermal insulation to ensure long-term, stable operation.

[0003] Existing heating and cooling pipes are usually composed of a protective pipe, a working pipe and an insulation layer. The protective pipe is placed on the outside of the working pipe and the insulation layer. At the same time, brackets are added to both ends of the pipe, and the working pipe and the protective pipe are welded and fixed to ensure that the working pipe will not deviate or shake in the protective pipe. Although this connection method is more stable, if the working pipe is damaged during actual use, the welded bracket needs to be cut off and the working pipe needs to be pulled out for repair, which is inconvenient for subsequent pipeline maintenance.

[0018] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0019] See also Figure 1-6The utility model provides a technical solution: a pipeline for a heating and cooling system, comprising a protection tube 1 and a working tube 2. The outer wall of the protection tube 1 is provided with a protective layer 3, and the inner wall of the protection tube 1 is provided with a plurality of guide grooves 4 in an array. Grooves 5 are provided at both ends of the guide grooves 4. An insulation layer 6 is bonded to the outer wall of the working tube 2. An annular block 7 is fixedly connected to the outer wall of each end of the working tube 2. A limiting groove 8 is provided in an array on one side of the annular block 7. An extrusion spring 9 is fixedly connected to the inner wall of the top end of the limiting groove 8. The bottom end of the extrusion spring 9 is fixedly connected to a limiting block 10. The side of the limiting block 10 away from the limiting groove 8 is fixedly connected to a limiting shaft 11. The limiting shaft 11 is corresponding to the limiting groove 8. A threaded section 12 is fixedly connected to both ends of the working tube 2. A threaded sleeve 13 with a threaded connection is sleeved on the threaded section 12. An extrusion ring 14 is fixedly connected to one side of the threaded sleeve 13. The protection tube 1 is sleeved on the outside of the working tube 2, and the limiting shaft 11 is corresponding to the limiting groove 8.

[0020] The threaded sleeve 13 is fixedly connected to a symmetrically arranged handle 15, the handle 15 is designed as a non-slip structure, the extrusion ring 14 is designed as a wedge-shaped structure, and the bottom end of the limit shaft 11 is designed as a wedge-shaped structure, which is convenient for rotating the threaded sleeve 13 through the handle 15, and then driving the extrusion ring 14 to extrude the limit shaft 11 through the threaded sleeve 13. The top of the limit shaft 11 is designed as a semicircular structure, and the cross-section of the groove 5 is designed as a semicircular structure, which is convenient for the top of the limit shaft 11 to be engaged with the groove 5. The limit block 10 is designed as a T-shaped structure, and the cross-section of the limit groove 8 is T-shaped, which is convenient for the limit groove 8 to limit the limit block 10.

[0021] Specifically, when using the present invention, after aligning the limit shaft 11 with the guide groove 4, the working tube 2 is inserted into the protective tube 1. After adjusting to the appropriate position, the threaded sleeve 13 is rotated by the handle 15, and the threaded sleeve 13 moves from the threaded section 12 toward the working tube 2. At the same time, the threaded sleeve 13 squeezes the limit shaft 11 through the extrusion ring 14, and the squeezed limit shaft 11 moves in the direction away from the axis of the working tube 2. When the limit shaft 11 is engaged with the groove 5, the rotation of the threaded sleeve 13 is stopped. At this time, the working tube 2 remains stable under the limiting action of the limit shaft 11. When the working tube 2 needs to be dismantled for maintenance, the threaded sleeve 13 is rotated in the opposite direction, and the threaded sleeve 13 drives the extrusion ring 14 to move in the direction away from the working tube 2. At the same time, the extrusion spring 9 squeezes the limit block 10, and the squeezed limit block 10 drives the limit shaft 11 to move toward the axis of the working tube 2. At this time, the limit shaft 11 is separated from the groove 5, and the working tube 2 can be pulled out.
