[0002] Perfluoroether is a terpolymer. In many structures, in order to improve the sealing performance, perfluoroether sealing rings are used to seal the structures, so as to ensure that gases or liquids will not leak. During long-term use, due to long-term extrusion and high temperature, the sealing rings need to be replaced. However, perfluoroether sealing rings often have external support structures, etc. This requires replacing both the external support structure and the perfluoroether sealing ring when replacing the perfluoroether sealing ring, which leads to waste.

[0020] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0021] As Figures 1 to 5 shown, the present utility model provides a perfluoroether high-temperature resistant sealing ring, which includes a support shell 1. A fixed threaded ring 2 is movably connected to the top end of the support shell 1. A threaded rod 3 is threadedly connected to the inner cavity of the fixed threaded ring 2. A moving threaded ring 5 is threadedly connected to the bottom of the threaded rod 3. A support fixing ring 6 is fixedly sleeved on the outer surface of the moving threaded ring 5. A sealing ring 7 is fixedly connected to the surface of the support fixing ring 6;

[0022] After the sealing ring 7 has been used for a long time, the user pinches the rotating piece 4 to rotate the threaded rod 3, so as to drive the threaded rod 3 to disengage from the inner cavity of the moving threaded ring 5. Then, the support fixing ring 6 is separated, and further the sealing ring 7 is separated. Then, the sealing ring 7 is taken out from the inner cavity of the support shell 1, so as to disassemble the sealing ring 7 that needs to be replaced. Then, a new sealing ring 7 is placed into the inner cavity of the support shell 1. Then, the rotating piece 4 is rotated so that the rotating piece 4 meshes with the moving threaded ring 5, so as to fix the support fixing ring 6, and further fix the new sealing ring 7, thus realizing the separate and rapid disassembly of the sealing ring 7 without causing waste of other components.

[0023] Wherein, a heat-conducting and heat-dissipating fin 10 is fixedly connected to the top end of the support fixing ring 6, and the heat-conducting and heat-dissipating fin 10 passes through the sealing ring 7 and is located outside;

[0024] Through the heat-conducting and heat-dissipating fin 10 at the top end of the support fixing ring 6, part of the heat received by the sealing ring 7 is transferred to the air, so that the sealing ring 7 can be quickly cooled, avoiding the situation that the sealing ring 7 has a high temperature for a long time, which may lead to a reduction in the service life of the sealing ring 7 and an increase in the replacement frequency.

[0025] Wherein, a rotating piece 4 is fixedly connected to the top end of the threaded rod 3. There are two threaded rods 3, and the two threaded rods 3 are located inside the left and right sides of the support shell 1;

[0026] Through the rotating piece 4 at the top end of the threaded rod 3, the user can hold the rotating piece 4 and rotate the threaded rod 3 to rotate, so that the threaded rod 3 can be screwed out or screwed into the inner cavity of the moving threaded ring 5, so that the sealing ring 7 can be installed or separated. And through the arrangement of the two threaded rods 3, the installation stability of the sealing rings 7 is improved.

[0027] Among them, installation grooves 11 are formed on both the left and right sides of the sealing ring 7, and the threaded rod 3 is located in the inner cavity of the installation groove 11;

[0028] Through the installation grooves 11 on both sides of the sealing ring 7, the installation grooves 11 can wrap the threaded rod 3, so that after the threaded rod 3 leaves the inner cavity of the moving threaded ring 5, it can be separated from the support fixing ring 6, thereby disassembling the sealing ring 7.

[0029] Among them, the support fixing ring 6 is circular, and the support fixing ring 6 is fixedly connected to the bottom of the inner cavity of the sealing ring 7;

[0030] Since the support fixing ring 6 is circular, the support fixing ring 6 can fixedly support the sealing ring 7 in all directions, thereby preventing the sealing ring 7 from deforming when subjected to side impacts.

[0031] Among them, there are multiple heat-conducting and heat-radiating fins 10, and the multiple heat-conducting and heat-radiating fins 10 are all arranged in the inner cavity of the sealing ring 7;

[0032] Through the arrangement of the multiple heat-conducting and heat-radiating fins 10, the heat-conducting and heat-radiating fins 10 can transfer the heat absorbed by the sealing ring 7 to the air for heat conduction and dissipation, and through the arrangement of the multiple heat-conducting and heat-radiating fins 10, it is ensured that the heat of the sealing ring 7 can be completely dissipated.

[0033] Among them, an asbestos heat-insulating cylinder 8 is fixedly connected to the inner cavity of the support shell 1, and a support cylinder 9 is fixedly connected to the inner cavity of the asbestos heat-insulating cylinder 8;

[0034] Through the asbestos heat-insulating cylinder 8 in the inner cavity of the support shell 1, the asbestos heat-insulating cylinder 8 can conduct heat insulation, and then through the support cylinder 9 to stably support the inner cavity of the sealing ring 7, thereby ensuring the sealing performance of the sealing ring 7.

[0035] The working principle and usage process of the present utility model: The sealing ring 7 is located in the inner cavity of the support shell 1. Then, the threaded rod 3 is screwed into the inner cavities of the fixed threaded ring 2 and the moving threaded ring 5 to fix the support fixing ring 6, and then through the support fixing ring 6 to support and fix the sealing ring 7. Then, during the use process, most of the heat is insulated by the asbestos heat-insulating cylinder 8;

[0036] Then, the heat of the sealing ring 7 is transferred to the air through the heat-conducting and heat-radiating fins 10, so as to quickly dissipate the heat received by the sealing ring 7, and the overall stability of the sealing ring 7 is improved through the support fixing ring 6;

[0037] When the sealing ring 7 needs to be replaced, pinch the rotating piece 4 by hand to rotate the threaded rod 3. Through the rotation of the threaded rod 3, the threaded rod 3 leaves the inner cavity of the moving threaded ring 5, and then separates from the support fixing ring 6, so that the sealing ring 7 can be taken out, and thus the support fixing ring 6, the sealing ring 7, and the heat-conducting and heat-radiating fin 10 can be replaced.
