Description

Technical Field

[0001] This utility model relates to the field of sealing device technology, and in particular to a high-temperature resistant sealing device. Background Technology

[0002] When a pipe leaks, a sealing device is needed for repair. The pipe sealing device, also known as a clamp, uses a pair of clamps to fix the damaged part of the pipe in order to repair the pipe.

[0003] The existing sealing devices have open ends on both sides of the clamp, and the rubber liner is in contact with the external environment. After long-term use, the rubber liner will age. When used in pipelines that transport high-temperature liquids or steam, the rubber liner is prone to deformation due to thermal expansion and contraction, thus losing its sealing function and the sealing performance is not stable enough.

[0004] Existing sealing devices do not have heat preservation functions. When high-temperature liquids or steam pass through the sealed area, energy will be lost due to cooling.

[0005] Therefore, a high-temperature resistant sealing device is proposed to solve the above problems. Utility Model Content

[0006] The purpose of this invention is to solve the problems of unstable sealing performance and lack of heat preservation function in existing sealing devices, and to propose a high-temperature resistant sealing device.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] A high-temperature resistant sealing device includes a clamp and a pipe. The clamp has an internal insulation component, connecting ears on both sides, extension pipes at both ends, a rubber liner on the inner wall, and sealing components at both ends.

[0009] Preferably, the inner wall of the clamp is provided with a groove for matching the rubber liner, the groove is fixedly connected to one side of the rubber liner, and the outer wall of the clamp is provided with a first mounting groove for matching the thermal insulation component.

[0010] Preferably, the extension tube has second mounting grooves at both ends for matching sealing components.

[0011] Preferably, the insulation component includes a plurality of square tubes, the bottom of which is fixedly connected to the surface of the first mounting groove, and a sealing plate is fixedly connected to the top of which.

[0012] Preferably, a vacuum layer is provided between the sealing plate and the first mounting groove.

[0013] Preferably, the sealing assembly includes a sealing ring, which is placed in a second mounting groove. A compression ring is provided on one side of the sealing ring, and one side of the compression ring is fixedly connected to one end of the extension tube. A pressure block matching the second mounting groove is fixedly connected to the bottom of the compression ring.

[0014] Preferably, the top of the sealing ring has a break, which is bonded together with adhesive.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] 1. This utility model, by setting up a heat insulation component, blocks the transfer of heat through a vacuum layer, thus preventing heat loss. By setting up multiple square tubes, the structural strength can be improved. When the pipe expands due to heat, the square tubes resist the expansion and wrap around it. When the pipe contracts, the square tubes pull it, thus preventing the vacuum layer from being damaged, achieving the effect of heat insulation and thus avoiding energy loss.

[0017] 2. This utility model utilizes the combined action of an extension tube and a sealing component. The extension tube seals both ends of the clamp, preventing the rubber liner from contacting the external environment. The sealing ring further seals both ends of the clamp. By setting a second mounting groove, the pressure block squeezes the sealing ring into the second mounting groove. This increases the sealing performance while preventing the sealing ring from contacting the external environment, thus avoiding corrosion of the sealing ring by the external environment and achieving the effect of improving sealing performance.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0026] Reference Figure 1-6 A high-temperature resistant sealing device includes a clamp 1 and a pipe 2. The clamp 1 has an internal heat insulation component, connecting ears 3 on both sides of the clamp 1, extension pipes 4 at both ends of the clamp 1, a rubber liner 5 on the inner wall of the clamp 1, and sealing components at both ends of the clamp 1.

[0027] It should be noted that there are two clamps 1, which are fixedly connected to each other by connecting ears 3, and the extension tube 4 is integrally formed with the clamp 1.

[0028] Furthermore, the inner wall of the clamp 1 is provided with a groove 6 that matches the rubber liner 5, and the groove 6 is fixedly connected to one side of the rubber liner 5. The outer wall of the clamp 1 is provided with a first mounting groove 7 that matches the thermal insulation component.

[0029] Furthermore, the two ends of the extension tube 4 are provided with second mounting grooves 8 for matching sealing components.

[0030] Furthermore, the insulation component includes multiple square tubes 9, the bottom of which is fixedly connected to the surface of the first mounting groove 7, and a sealing plate 10 is fixedly connected to the top of the square tubes 9. A vacuum layer 11 is provided between the sealing plate 10 and the first mounting groove 7.

[0031] The further advantage of adopting the above is that the heat transfer is blocked by the vacuum layer 11, thus avoiding heat loss. By setting multiple square tubes 9, the structural strength can be improved. When the pipe 2 expands due to heat, the square tubes 9 counteract the expansion. When the pipe 2 contracts, the square tubes 9 pull, thus preventing the vacuum layer 11 from being damaged.

[0032] Furthermore, the sealing assembly includes a sealing ring 12, which is placed in the second mounting groove 8. A compression ring 13 is provided on one side of the sealing ring 12. One side of the compression ring 13 is fixedly connected to one end of the extension tube 4. A pressure block 14 matching the second mounting groove 8 is fixedly connected to the bottom of the compression ring 13. A break 15 is provided on the top of the sealing ring 12, and the break 15 is bonded with glue.

[0033] The further advantage of the above-mentioned method is that by sealing both ends of the clamp 1 with the extension tube 4, the rubber liner 5 is prevented from contacting the external environment. The two ends of the clamp 1 are further sealed by the sealing ring 12. By setting the second mounting groove 8, the pressure block 14 squeezes the sealing ring 12 into the second mounting groove 8, which increases the sealing performance and prevents the sealing ring 12 from contacting the external environment, thereby preventing the sealing ring 12 from being corroded by the external environment.

[0034] During installation, the clamp 1 is installed near the damaged area of ​​the pipe 2. Then, the clamp 1 is moved along the pipe 2 to the damaged area so that the rubber liner 5 corresponds to the damaged area of ​​the pipe 2. Finally, the bolts at the connecting lugs 3 are tightened to seal the clamp 1. The sealing ring 12 is unfolded through the break 15 and placed on the pipe body at both ends of the clamp 1. The sealing ring 12 is glued from the break 15. After the glue solidifies, the sealing ring 12 is pushed into the second mounting groove 8. The compression ring 13 is joined along the pipe 2 to the area near the second mounting groove 8 and connected to the extension pipe 4 with bolts. After connection, the bolts are tightened. During the tightening process, the bolts drive the compression ring 13 to move toward the second mounting groove 8. At the same time, the pressure block 14 squeezes the sealing ring 12 into the second mounting groove 8.

[0035] In use, this invention blocks heat transfer through the vacuum layer 11, preventing heat loss. Multiple square tubes 9 enhance structural strength. When the pipe 2 expands due to heat, the square tubes 9 counteract the expansion; when the pipe 2 contracts, the square tubes 9 pull, preventing damage to the vacuum layer 11 and achieving insulation, thus avoiding energy loss. The extension tube 4 seals both ends of the clamp 1, preventing the rubber liner 5 from contacting the external environment. The sealing ring 12 further seals both ends of the clamp 1. The second mounting groove 8 is provided, and the pressure block 14 presses the sealing ring 12 into the second mounting groove 8, increasing sealing performance while preventing the sealing ring 12 from contacting the external environment, thus preventing corrosion of the sealing ring 12 and improving sealing performance.

[0036] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
