Description
Technical Field
[0001] The present application relates to the technical field of heating pipes, and more specifically, to a heating pipe connector. Background Art
[0002] Heating pipes are a system of pipes used to transport hot water or steam to the interior of a building. These pipes are usually installed in the walls, floors or underground, and provide heating by transferring heat to the interior of the building. Heating pipes are usually made of metal materials such as steel or copper, but plastic or other materials can also be used, depending on the environment and needs. These pipes are connected to the central heating system or boiler and transport hot water or steam to the areas that need heating through a circulation pump. In the heating pipe system, devices such as valves, radiators or radiators are also installed to control and regulate the distribution and output of heat.
[0003] Existing heating pipe joints are usually connected and assembled through one-piece welding, which has too high requirements on welding technology. If the quality of one-piece welding does not meet the standards, there may be tiny defects or cracks at the joints, which may cause gas or liquid to leak at the joints, resulting in reduced thermal insulation performance of the heating pipes. In addition, the air around the leaking joints may infiltrate into the pipe system, further affecting the temperature of the medium in the pipe. Utility Model Content

DETAILED DESCRIPTION
[0030] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application; obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments, and all other embodiments obtained by ordinary technicians in this field based on the embodiments in the present application without making creative work are within the scope of protection of the present application.
[0031] Reference Figure 1-Figure 5A heating pipe connector comprises a first pipe 1, a second pipe 2 is arranged on one side of the first pipe 1, a first butt joint ring 6 and a second butt joint ring 7 are arranged on one side of the first pipe 1 and the second pipe 2, and a sealing assembly is arranged inside the first butt joint ring 6 and the second butt joint ring 7;
[0032] The sealing assembly includes a thermal expansion block 13, which is located inside the first docking ring 6. A first sealing ring 14 is provided on one side of the thermal expansion block 13. A second sealing ring 15 is provided inside the second docking ring 7. One end of the first sealing ring 14 contacts the second sealing ring 15. The first sealing ring 14 and the second sealing ring 15 are used to seal when the first pipe 1 and the second pipe 2 are connected.
[0033] By setting up the sealing assembly, the gap at the connection between the first pipe 1 and the second pipe 2 can be effectively filled to prevent the heating liquid or gas from leaking through these gaps, ensure the good sealing performance of the heating pipe, reduce the possibility of temperature drop of the medium in the pipe, and maintain the stability and efficiency of the heating pipe.
[0034] When the first pipe 1 and the second pipe 2 of the heating pipe are connected, the first sealing ring 14 and the second sealing ring 15 are abutted against each other. When the temperature of the pipe rises, the heat expansion block 13 absorbs the heat of the pipe to expand, and then squeezes the first sealing ring 14, making it more tightly abutted against the second sealing ring 15, which can further enhance the sealing performance of the pipe connection.
[0035] Reference Figure 3-Figure 5 The outer walls of the first pipe 1 and the second pipe 2 are respectively fixedly connected with a first connecting ring 3 and a second connecting ring 4. One side of the first connecting ring 3 is fixedly connected with a threaded inner ring 12. One side of the second connecting ring 4 is fixedly connected with a threaded outer ring 16. The threaded inner ring 12 is threadedly connected with the threaded outer ring 16.
[0036] When the first pipeline 1 and the second pipeline 2 are connected, the threaded inner ring 12 and the threaded outer ring 16 are rotatably connected to facilitate installation.
[0037] Reference Figure 3-Figure 4 The outer sides of the first docking ring 6 and the second docking ring 7 are fixedly connected to the first connecting ring 3 and the second connecting ring 4 respectively. The first connecting ring 3 and the second connecting ring 4 are both provided with an insulation layer 11 inside. The outer side of the insulation layer 11 is provided with a heat insulation layer 10, and the heat insulation layer 10 is made of stainless steel.
[0038] The insulation layer 11 can be made of rock wool, which can effectively reduce heat conduction and reduce heat loss, thereby maintaining a stable temperature inside the heating pipe and improving the energy efficiency of the heating system. Rock wool is soft and bendable, easy to process, and can adapt to the requirements of various pipe shapes and sizes.
[0039] The heat insulation layer 10 is made of stainless steel, has good high temperature resistance, can effectively prevent heat conduction and loss, and has excellent corrosion resistance.
[0040] Reference Figure 3-Figure 4 The outer walls of the first connecting ring 3 and the second connecting ring 4 are fixedly connected with a fixing ring 9, wherein a plurality of threaded holes are opened inside one of the fixing rings 9, a threaded rod 5 is threadedly connected inside the plurality of threaded holes, and a fixing bolt 8 is threadedly connected at one end of the plurality of threaded rods 5.
[0041] After the first pipeline 1 and the second pipeline 2 are connected, the threaded rod 5 of the fixing ring 9 on one side is inserted into the threaded hole, and then fixed by the fixing bolt 8, so as to further ensure the tight connection between the first pipeline 1 and the second pipeline 2, and further reduce the leakage or water leakage of the first pipeline 1 and the second pipeline 2 at the connection point.
[0042] Reference Figure 1-Figure 5 The thermal expansion block 13 is made of fluororubber, and the first connecting ring 3 and the second connecting ring 4 have the same diameter.
[0043] Fluororubber has a high thermal expansion coefficient, so it will expand when heated. As the temperature rises, the fluororubber material will expand and occupy a larger space, and this expansion can be used to squeeze the first sealing ring 14 and the second sealing ring 15 to be connected more tightly.
[0044] Working principle: When in use, firstly, the threaded inner ring 12 of the first pipe 1 is rotationally connected with the threaded outer ring 16 of the second pipe 2. After the connection is completed, the threaded rod 5 of the fixing ring 9 on one side is inserted into the threaded hole, and then fixed by the fixing bolt 8, so as to further ensure the tight connection between the first pipe 1 and the second pipe 2. At this time, the first sealing ring 14 and the second sealing ring 15 are abutted. When the temperature of the pipe rises, the heat expansion block 13 absorbs the heat of the pipe to expand, and then squeezes the first sealing ring 14, so that it abuts against the second sealing ring 15 more closely, which can further enhance the sealing performance of the pipe connection.
[0045] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
