Description

Technical Field

[0001] The utility model relates to the technical field of pipeline thermal insulation, in particular to an easily detachable pipeline thermal insulation sleeve. Background Art

[0002] Pipelines are used to transport oil, natural gas, water or other flowing liquids. Pipelines can withstand certain high pressures and temperatures, and are corrosion-resistant, acid-resistant and alkali-resistant. Compared with other modes of transportation, pipeline transportation has the advantages of low cost and low failure rate. In some fields, pipeline transportation is an excellent choice.

[0003] In the use of hot water pipes, the hot water inside the pipes needs to be insulated to prevent the hot water from cooling down quickly. The current pipe insulation devices do not have the feature of easy disassembly. When the pipes need to be repaired, it is troublesome to remove the insulation devices. Secondly, the insulation devices cannot be well aligned and installed during the installation process, and there are no positioning and temporary fixing devices. Finally, the insulation devices need to be connected, and they also need to be easy to disassemble. It is also necessary to be able to connect the insulation devices to insulate the pipes to form a sealed environment to avoid the temperature loss of the transported hot water and external rainwater from entering between the pipes and the insulation devices. Therefore, an easily detachable pipe insulation cover is proposed to address the above problems. Utility Model Content

[0022] See also Figure 1-3 , the utility model provides a technical solution:

[0023] A pipe insulation sleeve that is easily disassembled comprises an upper shell 1, a lower shell 2 and an insulation layer 3, wherein the insulation layer 3 is fixedly connected inside the upper shell 1, a positioning rod 4 is fixedly connected to the outer side of the upper shell 1, a connecting plate 5 is fixedly connected to the outer side of the upper shell 1 near the edge, a positioning groove 6 is provided on the outer side of the lower shell 2, a vertical plate 7 is fixedly connected to the outer side of the lower shell 2 near the edge, a horizontal axis 8 is fixedly connected between the two vertical plates 7, a fixed block 9 is rotatably connected to the outer side of the horizontal axis 8, one end of the fixed block 9 is fixedly connected to a screw rod 10, a nut 11 is threadedly connected to the outer side of the screw 10, one end of the upper shell 1 is fixedly connected to a connecting pipe 12, an annular groove 13 is provided on the outer side of the connecting pipe 12, and a rubber ring 14 is fixedly connected to the outer side of the connecting pipe 12.

[0024] The end of the upper shell 1 away from the connecting pipe 12 is fixedly connected to the main pipe 15, and the outer side of the main pipe 15 is fixedly connected to the shell 16. The top of the shell 16 is provided with a through hole 17 penetrating the shell 16, and the through hole 17 is provided inside a pin 18. The outer side of the pin 18 is fixedly connected to a baffle 19, the top of the baffle 19 is provided with a spring 20, and the top of the pin 18 is fixedly connected to a pull ring 21; the cross-sectional shape of the upper shell 1 and the lower shell 2 is a semicircle with equal diameter; the number of the positioning rods 4 and the positioning grooves 6 are both four; the outer diameter of the rubber ring 14 and the connecting pipe 12 is slightly smaller than the inner diameter of the main pipe 15.

[0025] Workflow: When it is necessary to insulate the pipeline, first select a suitable insulation device according to the diameter of the pipeline. Before wrapping the pipeline with the insulation device, remove the debris on the outside of the pipeline manually, and then put the upper shell 1 on the top of the pipeline, and the insulation layer 3 is in direct contact with the pipeline. After the upper shell 1 is placed, the lower shell 2 is attached to the outside of the pipeline from the bottom of the pipeline, and the positioning rod 4 on the upper shell 1 enters the positioning groove 6 on the lower shell 2, and then slide the upper shell 1 toward the main pipe 15. The positioning rod 4 will be engaged with the positioning groove 6, so that the upper shell 1 and the lower shell 2 can be accurately connected together, and the engagement of the positioning rod 4 and the positioning groove 6 can temporarily fix the insulation device on the outside of the pipeline, and then, screw the nut 11 to a position away from the fixing block 9, and rotate the screw 10 around the horizontal axis 8 through the fixing block 9. The screw 10 enters the groove of the connecting plate 5, and the installer can directly tighten the nut 11 by hand. Under the action of the connecting plate 5 and the vertical plate 7, the upper shell 1 and the lower shell 2 are connected. The shell 2 is tightly fixed together. When it is necessary to repair or inspect the pipeline, the nut 11 can be loosened to separate the upper shell 1 and the lower shell 2, so that the pipeline insulation device can be easily disassembled. After a single insulation device is installed, the connecting pipe 12 of a group of insulation devices can be inserted into the main pipe 15 of a group of insulation devices next door. The pull ring 21 above the shell 16 can be pulled upward to pull the pin 18 in the through hole 17. The spring 20 is compressed under the action of the baffle 19. When the rubber ring 14 on the outer side of the connecting pipe 12 is against the inner wall of the main pipe 15, the pull ring 21 is released, and the pin 18 is stuck in the inside of the annular groove 13 under the elastic force of the spring 20, so that the connecting pipe 12 and the main pipe 15 are connected, and the two-to-two connection between the insulation devices is realized. The rubber ring 14 can prevent external rainwater from entering between the insulation device and the pipeline through the gap at the connection, affecting the use of the pipeline. The device as a whole adopts a convenient disassembly design, which can reduce the tools and time required for disassembly and reduce unnecessary cost output.
