Description

Technical Field

[0001] This utility model belongs to the technical field of pipeline insulation components, specifically relating to an insulation sleeve for a tee joint. Background Technology

[0002] In automotive development, pipes connecting heat sources are primarily used to transfer heat or cooling media to achieve functions such as engine cooling and cabin heating. However, to prevent heat from damaging other automotive components, these heat-generating pipes in critical locations require heat insulation. During the insulation process, the insulation of the T-joint location is challenging due to the complex structure of the pipe joint. Current methods typically involve wrapping multiple layers of insulation film or pads around the T-joint. This approach presents the following technical problems:

[0003] (1) Manual winding requires adjusting the tightness of each turn, which is cumbersome and depends on the worker's experience, resulting in poor consistency during mass production.

[0004] (2) Under high temperature conditions (such as the engine compartment being at 80-120℃ for a long time, or even exceeding 120℃ in some places), the multi-layered insulation material is prone to displacement and detachment between the layers due to thermal expansion and contraction, or damage due to interlayer friction caused by vibration, thus losing its insulation function.

[0005] (3) The entire winding layer needs to be removed for later maintenance, which has poor reusability and may damage the insulation material, increasing maintenance costs.

[0006] Therefore, there is a need to provide an improved technical solution that addresses the shortcomings of the existing technology. Utility Model Content

[0007] The purpose of this utility model is to provide a heat insulation sleeve for a tee joint, so as to solve the problems of low installation efficiency, poor reliability and high maintenance cost in the existing heat insulation treatment of tee joints.

[0008] To achieve the above objectives, the heat-insulating sleeve at the tee joint of this utility model provides the following technical solution:

[0009] A heat-insulating sleeve for a tee joint includes a first rectangular wrapping area, with both ends of the first wrapping area detachably fixedly connected to form a sleeve structure for wrapping a pipe; a second wrapping area and a third wrapping area are spaced apart on one side of the first wrapping area along its length extension direction, the length extension directions of the second and third wrapping areas being perpendicular to the length extension direction of the first wrapping area; both ends of the second and third wrapping areas are detachably fixedly connected to form sleeve structures for wrapping pipes; a connecting area is integrally provided between the second and third wrapping areas, and the second and third wrapping areas are integrally fixedly connected to the first wrapping area through the connecting area; the connecting area is used to protect the central area of ​​the tee joint.

[0010] As a further optimized technical solution, the second and third parcel areas are respectively provided with cutting marks at the end near the first parcel area, so as to facilitate the disconnection of the second and third parcel areas from the first parcel area.

[0011] As a further optimized technical solution, the two ends of the first package area are provided with first movable connectors to achieve detachable connection between the two ends of the first package area; the two ends of the second package area are provided with second movable connectors to achieve detachable connection between the two ends of the second package area; and the two ends of the third package area are respectively provided with third movable connectors to achieve detachable connection between the two ends of the third package area.

[0012] As a further optimized technical solution, the first movable connector, the second movable connector and the third movable connector are all push-button type snap fasteners.

[0013] As a further optimized technical solution, at least one set of the first movable connector is arranged, and the first movable connector is arranged at intervals along the length and / or width direction of the first package area.

[0014] As a further optimized technical solution, at least one set of the second movable connector is arranged, and the second movable connector is arranged at intervals along the length and / or width direction of the second wrapping area.

[0015] As a further optimized technical solution, at least three sets of the third movable connector are arranged, and the third movable connector is arranged at intervals along the length and / or width of the third wrapping area.

[0016] As a further optimized technical solution, the first movable connector, the second movable connector, and the third movable connector are all Velcro fasteners. The Velcro fasteners extend along the length of the first wrapping area, the second wrapping area, and the third wrapping area to adjust the tightness of the connection.

[0017] As a further optimized technical solution, the heat insulation sleeve at the tee joint is provided with at least an insulation layer and a protective layer from the side facing the pipe to the side away from the pipe.

[0018] As a further optimized technical solution, the protective layer is aluminum foil or tin foil, and the insulation layer is insulation fiber or insulation cotton.

[0019] Beneficial effects:

[0020] (1) This utility model wraps a pipe with the first wrapping area, the second and third wrapping areas correspond to the other two pipes, and the connecting area is used to protect the central area of ​​the tee joint, thereby realizing that the cut integrated heat insulation sleeve is directly wrapped on the outside of the tee joint without multiple layers of wrapping, which significantly improves assembly efficiency and consistency and effectively improves operation efficiency.

[0021] (2) The integral structure fixes the relative positions of each wrapping area through the connection area. Compared with the multi-layer arrangement in the prior art, it reduces the displacement, detachment or wear between the multi-layers caused by thermal expansion and contraction or vibration under high temperature environment, and extends the thermal insulation life.

[0022] (3) The detachable connection design allows for the separate disassembly of the local wrapping area for maintenance without damaging the overall structure, which effectively improves the reusability of the sheath and reduces maintenance losses. Attached Figure Description

[0034] Example 1

[0035] This utility model provides a heat-insulating sleeve for a tee joint, such as Figure 1 As shown, the heat insulation sleeve includes a first wrapping area 1, a second wrapping area 2, a third wrapping area 3, and a connecting area 4. The first wrapping area 1 is rectangular, with detachable fixed connections at both ends, allowing for convenient and quick wrapping of a pipe to form a sleeve structure that fits snugly against the outer wall of the pipe. On one side of the first wrapping area 1, two equally rectangular second wrapping areas 2 and 3 are spaced apart, their lengths perpendicular to the first wrapping area 1. The ends of the second and third wrapping areas 2 and 3 are also detachable fixed connections, enabling them to respectively form sleeve structures for wrapping the remaining two pipes. An integrally formed connecting area 4 is provided between the second and third wrapping areas 2 and 3. This connecting area is also integrally fixedly connected to the first wrapping area 1, ensuring the stability and continuity of the overall structure. Furthermore, the connecting area 4 precisely covers and protects the central area of ​​the tee connector 5.

[0036] To facilitate disconnecting the second parcel area 2 and the third parcel area 3 from the first parcel area 1, cutting marks 6 are respectively set at the ends of the second parcel area 2 and the third parcel area 3 near the first parcel area 1.

[0037] like Figure 2 As shown, to facilitate the detachable connection of the two ends of the first packaging area 1, the second packaging area 2, and the third packaging area 3, a first movable connector 7 is arranged at both ends of the first packaging area 1, a second movable connector 8 is arranged at both ends of the second packaging area 2, and a third movable connector 9 is arranged at both ends of the third packaging area 3. Thus, the two ends of the first packaging area 1 are connected by the first movable connector 7 to form a sleeve structure; similarly, the two ends of the second packaging area 2 are connected by the second movable connector 8 to form a sleeve structure, and the two ends of the third packaging area 3 are connected by the third movable connector 9 to form a sleeve structure.

[0038] In this embodiment, the first movable connector 7, the second movable connector 8, and the third movable connector 9 are all push-button type snap fasteners. Specifically, taking the first movable connector 7 as an example, the male snap fastener of the first movable connector 7 is fixedly disposed at one end of the first wrapping area 1, and the female snap fastener of the first movable connector 7 is fixedly disposed at the other end of the first wrapping area 1. When it is necessary to wrap the pipe, the two ends of the first wrapping area 1 are bent relative to each other and wrapped around the outer wall of the pipe, and then the male and female snap fasteners are fastened together. The installation methods of the second movable connector 8 and the third movable connector 9 are similar to those of the first movable connector 7, and will not be described in detail here.

[0039] In this embodiment, a set of the first movable connector 7, the second movable connector 8, and the third movable connector 9 are all provided. In actual production, this utility model is available in different models to suit pipe diameters of different sizes.

[0040] In this embodiment, the heat insulation sleeve at the tee joint is provided with at least an insulation layer and a protective layer from the side facing the pipe to the side away from the pipe. The protective layer is made of aluminum foil or tin foil, which can efficiently reflect heat and reduce heat transfer to the outside. The insulation layer is made of insulation fiber or insulation cotton, which has good heat insulation performance and can effectively prevent heat loss and further improve the heat insulation effect.

[0041] In practical use, firstly, wrap the first wrapping area 1 around one of the pipes, accurately aligning and pressing the snap-fit ​​couplings at both ends of the first wrapping area 1 to quickly form a tightly wrapped sleeve structure. Then, wrap the second wrapping area 2 around one of the pipes perpendicular to the one wrapped by the first wrapping area 1, similarly snapping the snap-fit ​​couplings at both ends of the second wrapping area 2 to complete the wrapping of that pipe. Finally, wrap the third wrapping area 3 around the last pipe, snapping the snap-fit ​​couplings at both ends of the third wrapping area 3. During this process, the connecting area 4 will naturally and tightly cover the central area of ​​the tee connector 5, completing the installation of the entire thermal insulation sleeve. This installation method is simple and convenient, requiring no complicated adjustment steps, effectively improving installation efficiency.

[0042] Example 2

[0043] like Figure 4 As shown, the main difference between this embodiment and Embodiment 1 is the different numbers of the first movable connector 7, the second movable connector 8, and the third movable connector 9 installed. In this embodiment, multiple sets of the first movable connector 7 are arranged, and the first movable connector 7 are spaced apart along the length and width of the first wrapping area 1. Multiple sets of the second movable connector 8 are arranged, and the second movable connector 8 are spaced apart along the length and width of the second wrapping area 2. Multiple sets of the third movable connector 9 are arranged, and the third movable connector 9 are spaced apart along the length and width of the third wrapping area 3. It should be noted that multiple sets of male and female buckles in the width direction of any wrapping area refer to the same number of female and male buckles, while multiple sets of male and female buckles along the length direction can refer to the same number of female and male buckles being engaged separately, or multiple sets of female buckles and one set of female buckles or multiple sets of female buckles and one set of female buckles having multiple engagement positions, thereby forming sleeve structures of different pipe diameters. In this way, multiple sets of male and female couplings arranged along the width direction can ensure the strength of the connection, while the male and female couplings arranged along the length direction can adjust the inner diameter of the sleeve structure during the fitting process. This makes the present invention more flexible to adapt to pipes of different diameters and can meet the thermal insulation installation requirements of various specifications of pipes.

[0044] Example 3

[0045] The main difference between this embodiment and Embodiment 2 is that the number of the first movable connector 7, the second movable connector 8, and the third movable connector 9 installed is different. In this embodiment, multiple sets of the first movable connector 7 are arranged at intervals along the length of the first wrapping area 1, multiple sets of the second movable connector 8 are arranged at intervals along the length of the second wrapping area 2, and multiple sets of the third movable connector 9 are arranged at intervals along the length of the third wrapping area 3. At this time, only the inner diameter of the sleeve structure can be adjusted, so that this utility model can adapt to pipes of different diameters.

[0046] Example 4

[0047] The main difference between this embodiment and Embodiment 2 lies in the different quantities of the first movable connector 7, the second movable connector 8, and the third movable connector 9. In this embodiment, multiple sets of the first movable connector 7 are arranged at intervals along the width direction of the first packaging area 1, multiple sets of the second movable connector 8 are arranged at intervals along the width direction of the second packaging area 2, and multiple sets of the third movable connector 9 are arranged at intervals along the width direction of the third packaging area 3. At this time, when the snap fasteners are engaged, the firmness of the connection between the two ends of the packaging area can be guaranteed.

[0048] Example 5

[0049] like Figure 5 As shown, the main difference between this embodiment and Embodiment 1 lies in the specific implementation methods of the first movable connector 7, the second movable connector 8, and the third movable connector 9. In this embodiment, the first movable connector 7, the second movable connector 8, and the third movable connector 9 are all Velcro fasteners. The Velcro fasteners extend along the length of the first wrapping area 1, the second wrapping area 2, and the third wrapping area 3, allowing for flexible adjustment of the Velcro fastening position according to the diameter of the main pipe, thus adjusting the tightness of the connection.

[0050] It is understood that the above description is merely exemplary and the embodiments of this application do not limit the scope of the application.

[0051] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be within the scope of protection of the pending claims of the present utility model.
