Description

Technical Field

[0001] This utility model relates to the field of thermal insulation pipe technology, and in particular to a high-temperature resistant rubber and plastic thermal insulation pipe. Background Technology

[0002] Rubber and plastic insulation pipes are widely used in many fields due to their excellent insulation, moisture-proof, and corrosion-resistant properties. They are made from rubber and plastics (such as PVC and NBR) through a foaming process. These pipes are bonded to the surface of equipment or pipes using glue or tape. However, existing rubber and plastic insulation pipe designs are quite rudimentary. During installation, the pipe needs to be wrapped around the pipe surface. The inner wall of the pipe is made of rubber and plastic material with high friction resistance, and the pipe surface often has rough rust. Therefore, the friction resistance between the pipe and the inner wall of the insulation pipe is very high, making it difficult to easily fit the insulation pipe onto the pipe surface. Utility Model Content

[0003] The problem this invention aims to solve is that the frictional resistance between the pipe and the inner wall of the rubber-plastic insulation pipe is very high, making it difficult to easily attach the rubber-plastic insulation pipe to the pipe surface.

[0004] To solve the above-mentioned technical problems, this utility model provides a high-temperature resistant rubber and plastic insulation pipe, including an insulation pipe body. The insulation pipe body includes a high-temperature resistant layer and a rubber and plastic pipe layer. The high-temperature resistant layer is disposed on the outer surface of the rubber and plastic pipe layer. Multiple conveying plates are slidably connected inside the rubber and plastic pipe layer and are arranged along the length direction of the rubber and plastic pipe layer. Both ends of the multiple conveying plates are provided with connecting rods that are slidably connected to the insulation pipe body to drive the conveying plates to move between the inside of the rubber and plastic pipe layer and the inner wall surface. Multiple arc conveying blocks are equidistantly arranged at one end of the conveying plate near the inside of the rubber and plastic pipe layer in the length direction.

[0005] Preferably, the high-temperature resistant layer includes an aluminum foil layer, a fiberglass mesh, and a high-temperature resistant coating. The high-temperature resistant coating is disposed on the outer surface of the rubber-plastic tube layer, the fiberglass mesh is disposed on the outer surface of the high-temperature resistant coating, and the aluminum foil layer is disposed on the outer surface of the fiberglass mesh.

[0006] Preferably, the inner wall of the rubber-plastic tube layer is provided with a groove that is slidably connected to the conveyor plate.

[0007] Preferably, the plurality of the grooves are arranged at equal intervals along the radial direction of the insulation pipe body.

[0008] Preferably, the plurality of the grooves are arranged at equal intervals along the length of the insulation pipe.

[0009] Preferably, the high-temperature resistant layer and the rubber-plastic tube layer have a through-hole for mounting, and a fixing shell that is slidably connected to the connecting rod is provided inside the mounting hole.

[0010] Preferably, the fixing shell is an annular structure, the inner wall of the fixing shell is provided with a first limiting part, and the surface of the connecting rod is provided with a second limiting part that engages with the first limiting part.

[0011] Preferably, the end of the mounting hole away from the outer surface of the insulation pipe is connected to the sliding groove.

[0012] Preferably, the end of the connecting rod away from the conveying plate extends to the outside of the insulation pipe body and is provided with a joint.

[0013] Preferably, the outer surface of the aluminum foil layer is provided with a plurality of square embossed blocks.

[0014] Compared with the prior art, this utility model provides a high-temperature resistant rubber and plastic insulation pipe, which has the following characteristics:

[0015] Beneficial effects:

[0016] 1. This utility model incorporates a high-temperature resistant layer, a rubber-plastic pipe layer, a conveying plate, an arc-shaped conveying block, and a connecting rod. The high-temperature resistant layer, located on the outer surface of the rubber-plastic pipe layer, increases its high-temperature resistance, thereby improving the high-temperature resistance of the insulation pipe body. The arc-shaped conveying block, positioned at the upper end of the conveying plate along the length of the rubber-plastic pipe layer, reduces friction on the inner wall of the rubber-plastic pipe layer, thus lowering the frictional resistance between the outer surface of the pipe and the inner wall of the rubber-plastic pipe layer. This facilitates the installation of the insulation pipe body on the outer surface of the pipe. The connecting rod, slidably connected to the insulation pipe body, moves the conveying plate between the inside of the rubber-plastic pipe layer and its inner wall surface. After the pipe and the rubber-plastic insulation pipe are installed, the pipe and the inside of the rubber-plastic pipe layer are in full contact, reducing the convection space between the outer surface of the pipe and the rubber-plastic pipe layer, reducing heat conduction, and improving the insulation effect of the pipe. This solves the problem of excessive frictional resistance between the pipe and the inner wall of the rubber-plastic insulation pipe, which makes it difficult to easily fit the rubber-plastic insulation pipe onto the pipe surface.

[0023] This utility model relates to a high-temperature resistant rubber and plastic insulation pipe, such as Figure 1-5 As shown, the device includes an insulated pipe body 1, which comprises a high-temperature resistant layer 101 and a rubber-plastic pipe layer 102. The high-temperature resistant layer 101 is disposed on the outer surface of the rubber-plastic pipe layer 102. Multiple conveying plates 2 are slidably connected inside the rubber-plastic pipe layer 102, arranged along its length. Connecting rods 3 are slidably connected to both ends of the multiple conveying plates 2, which in turn move the conveying plates 2 between the inside of the rubber-plastic pipe layer 102 and its inner wall surface. Multiple arc-shaped conveying blocks 4 are equidistantly spaced along the length of one end of the conveying plate 2 near the inside of the rubber-plastic pipe layer 102. By setting the high-temperature resistant layer 101 and the rubber-plastic pipe layer 102, and by placing the high-temperature resistant layer 101 on the outer surface of the rubber-plastic pipe layer 102, the high-temperature resistance of the outer surface of the rubber-plastic pipe layer 102 is increased, thereby improving the high-temperature resistance of the insulated pipe body 1. The arrangement of the conveying plates 2 and the arc-shaped conveying blocks further enhances the insulation's overall performance. The conveying block 4, located on the upper end of the conveying plate 2, is arranged along the length of the rubber-plastic pipe layer 102. This reduces the frictional force on the inner wall of the rubber-plastic pipe layer 102, thereby reducing the frictional resistance between the outer surface of the pipe and the inner wall of the rubber-plastic pipe layer 102. This facilitates the installation of the insulation pipe body 1 on the outer surface of the pipe. A connecting rod 3 is provided and slidably connected to the insulation pipe body 1, causing the conveying plate 2 to move between the inside of the rubber-plastic pipe layer 102 and the inner wall surface. After the pipe and the rubber-plastic insulation pipe are installed, the pipe and the inside of the rubber-plastic pipe layer 102 are in full contact, reducing the convection space between the outer surface of the pipe and the rubber-plastic pipe layer 102, reducing heat conduction, and improving the insulation effect of the pipe. This solves the problem that the frictional resistance between the pipe and the inner wall of the rubber-plastic insulation pipe is too high, making it difficult to easily fit the rubber-plastic insulation pipe onto the pipe surface.

[0024] In an embodiment of this utility model, the high-temperature resistant layer 101 includes an aluminum foil layer 111, a fiberglass mesh 112, and a high-temperature resistant coating 113. The high-temperature resistant coating 113 is disposed on the outer surface of the rubber-plastic tube layer 102, the fiberglass mesh 112 is disposed on the outer surface of the high-temperature resistant coating 113, and the aluminum foil layer 111 is disposed on the outer surface of the fiberglass mesh 112. By disposing of the aluminum foil layer 111, the fiberglass mesh 112, and the high-temperature resistant coating 113, the high-temperature resistant coating 113 improves the high-temperature resistance of the rubber-plastic tube layer 102 and fixes the fiberglass mesh 112 to the outer surface of the rubber-plastic tube layer 102. The fiberglass mesh 112 improves the structural strength of the high-temperature resistant layer 101, and the aluminum foil layer 111 improves the waterproof, anti-fouling, and surface protection capabilities of the insulation tube body 1.

[0025] In an embodiment of this utility model, a groove 5 is provided on the inner wall of the rubber-plastic tube layer 102 to slide and connect with the conveyor plate 2. By providing the groove 5, the conveyor plate 2 can slide between the inside of the rubber-plastic tube layer 102 and the inner wall surface, thereby improving the stability of the movement of the conveyor plate 2.

[0026] In this embodiment of the utility model, multiple sliding grooves 5 are arranged at equal intervals along the radial direction of the insulation pipe body 1. By arranging multiple sliding grooves 5 at equal intervals along the radial direction of the insulation pipe body 1, it is convenient for the arc conveying block 4 to make uniform contact with the pipe surface.

[0027] In this embodiment of the utility model, multiple sliding grooves 5 are equidistantly arranged along the length of the insulation pipe body 1. By equidistantly arranging multiple sliding grooves 5 along the length of the insulation pipe body 1, the conveying plate 2 is segmented, which facilitates the control of the movement of the conveying plate 2, thereby facilitating full contact between the arc conveying block 4 and the outer surface of the pipe, and also facilitating the segmented installation of the insulation pipe body 1.

[0028] In an embodiment of this utility model, a mounting hole 6 is provided through the interior of the high-temperature resistant layer 101 and the rubber-plastic tube layer 102. A fixing shell 7 is provided inside the mounting hole 6 and is slidably connected to the connecting rod 3. By providing the mounting hole 6 and the fixing shell 7, the fixing shell 7 is fixed inside the heat insulation tube 1 through the mounting hole 6. The fixing shell 7 facilitates the connecting rod 3 to move back and forth along the tangential direction inside the heat insulation tube 1.

[0029] In this embodiment of the utility model, the fixing shell 7 is a ring-shaped structure. The inner wall of the fixing shell 7 is provided with a first limiting part 8, and the surface of the connecting rod 3 is provided with a second limiting part 9 that engages with the first limiting part 8. By providing the first limiting part 8 and the second limiting part 9, and by engaging the first limiting part 8 with the second limiting part 9, the connecting rod 3 is fixed to the fixing shell 7, and the arc conveying block 4 is fixed to the inner wall surface of the rubber and plastic tube layer 102.

[0030] In this embodiment of the utility model, the end of the mounting hole 6 away from the outer surface of the insulation pipe body 1 is connected to the slide groove 5. By setting the end of the mounting hole 6 away from the outer surface of the insulation pipe body 1 to be connected to the slide groove 5, it is convenient for the connecting rod 3 to move back and forth inside the slide groove 5 and the mounting hole 6.

[0031] In this embodiment of the utility model, the connecting rod 3 extends to the outside of the insulation pipe body 1 at the end away from the conveying plate 2 and is provided with a joint 10. By providing the joint 10, it is convenient for the user to push and pull the connecting rod 3. By pushing the connecting rod 3 into the insulation pipe body 1, the first limiting part 8 and the second limiting part 9 are engaged, and the connecting rod 3 is fixed to the fixed shell 7, so that the arc conveying block 4 is on the inner wall surface of the rubber and plastic pipe layer 102. When the connecting rod 3 is pulled away from the insulation pipe body 1, the first limiting part 8 and the second limiting part 9 are separated, and the arc conveying block 4 is placed inside the slide groove 5.

[0032] In an embodiment of this utility model, a plurality of square embossed blocks 11 are provided on the outer surface of the aluminum foil layer 111. By providing square embossed blocks 11, the structural strength of the aluminum foil layer 111 is improved and the friction of the aluminum foil layer 111 is increased.

[0033] In use, firstly, a high-temperature resistant layer 101 and a rubber-plastic pipe layer 102 are set. The high-temperature resistant layer 101 is set on the outer surface of the rubber-plastic pipe layer 102 to increase the high-temperature resistance of the outer surface of the rubber-plastic pipe layer 102. Secondly, a conveyor plate 2 and an arc-shaped conveyor block 4 are set. The arc-shaped conveyor block 4 is set on the upper end of the conveyor plate 2, so that the arc-shaped conveyor block 4 is set along the length of the rubber-plastic pipe layer 102, reducing the frictional force on the inner wall of the rubber-plastic pipe layer 102. This reduces the frictional resistance between the outer surface of the pipe and the inner wall of the rubber-plastic pipe layer 102, thus facilitating the installation of the insulation pipe body 1 on the outer surface of the pipe. Push the connecting rod 3 into the interior of the insulation pipe body 1. At this time, the first limiting part 8 and the second limiting part 9 are engaged, and the connecting rod 3 is fixed to the fixed shell 7, so that the arc conveying block 4 is on the inner wall surface of the rubber and plastic pipe layer 102. Pull the connecting rod 3 away from the insulation pipe body 1. At this time, the first limiting part 8 and the second limiting part 9 are separated, so that the arc conveying block 4 is in the sliding groove 5. After the pipe and the rubber and plastic insulation pipe are installed, the pipe and the interior of the rubber and plastic pipe layer 102 are in full contact, reducing the convection space between the outer surface of the pipe and the rubber and plastic pipe layer 102, reducing heat conduction, and making the pipe insulation effect better.
