It has good specific thermal shock performance, good heat-insulating performance, and good resistance to aluminum infiltration. By designing a multi-layer structure to reduce heat conduction, the temperature of the fluid can be maintained, energy loss can be reduced, and the energy-saving requirements of engineering applications can be met.

The traditional single-sealing-ring design may require the entire diversion pipe to be disassembled to replace the sealing ring, which often means that more components need to be disassembled, increasing the complexity and time of replacement. The single sealing ring reduces the service life. For this reason, we propose a lightweight heat-insulating diversion pipe. Content of the Utility Model

[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] Embodiment 1:
[0022] Please refer to the attached Figure 1 -attached Figure 4, a lightweight heat-insulating diversion pipe, comprising a diversion structure 1. The diversion structure 1 includes a diversion pipe 11 and a limiting pipe 12. Inner threads are respectively arranged on the inner walls at both ends of the diversion pipe 11. One end of the diversion pipe 11 is the water inlet end, and the other end is the water outlet end. The number of the limiting pipes 12 is two. External threads are arranged on the outer wall of one end of the limiting pipe 12, and internal threads are arranged at one end of the inner wall of the limiting pipe 12 far from the external threads. The external threads of the limiting pipe 12 are matched with the internal threads of the diversion pipe 11. An adjusting structure 2 is arranged inside the diversion pipe 11. The adjusting structure 2 includes a rotating shaft 21. The rotating shaft 21 is rotatably installed inside the diversion pipe 11. One end of the rotating shaft 21 passes through the diversion pipe 11 and extends to the outside of the diversion pipe 11. The rotating shaft 21 is rotatably connected with the inner wall of the diversion pipe 11. A turntable 22 is fixedly installed at the top end of the rotating shaft 21. A partition plate 23 is fixedly installed on the rotating shaft 21. The number of the partition plates 23 is set to two. Sealing rings 24 are detachably installed on both sides of the rotating shaft 21 inside the diversion pipe 11. The partition plates 23 are in contact with the sealing rings 24. The end of the limiting pipe 12 abuts against the sealing rings 24. A first connection structure 3 is arranged at the water inlet end of the diversion pipe 11. The first connection structure 3 includes a first connection sleeve 31 and a first connection head 32. The first connection sleeve 31 and the first connection head 32 are fixedly connected. External threads are arranged on the outer wall of the first connection head 32. External threads are arranged on the outer wall of one end of the first connection sleeve 31 far from the first connection head 32. The external threads of the first connection head 32 are matched with the internal threads of the limiting pipe 12. A second connection structure 5 is arranged at the water outlet end of the diversion pipe 11. The second connection structure 5 includes a second connection sleeve 51 and a second connection head 52. The second connection sleeve 51 and the second connection head 52 are fixedly connected. External threads are arranged on the outer wall of the second connection head 52. External threads are arranged on the outer wall of one end of the second connection sleeve 51 far from the second connection head 52. The external threads of the second connection head 52 are matched with the internal threads of the limiting pipe 12.
[0023] Water is passed into the first connecting sleeve 31. The water enters the limiting pipe 12 and the diversion pipe 11 from the first connecting sleeve 31 and the first connector 32, and then flows out from the second connecting sleeve 51 and the second connector 52. The turntable 22 is rotated, and the rotating shaft 21 is driven by the turntable 22 to rotate on the diversion pipe 11. The partition plate 23 is driven to rotate by the rotating shaft 21, and the flow space inside the diversion pipe 11 is controlled by the rotation of the partition plate 23, thereby controlling the rate and flow of the water flow. Since the partition plate 23 contacts the sealing ring 24, the water tightness is improved through the sealing ring 24. However, after long-term use, the partition plate 23 will wear the sealing ring 24, resulting in water leakage. At this time, only need to unscrew the first connecting sleeve 31 from the limiting pipe 12, and then unscrew the limiting pipe 12 from the diversion pipe 11. Because there are two sealing rings 24, the two sealing rings 24 can be removed and replaced respectively. After replacing the sealing ring 24, screw the limiting pipe 12 into the diversion pipe 11. Since the end of the limiting pipe 12 contacts the sealing ring 24, when the limiting pipe 12 is screwed into the diversion pipe 11, it will drive the sealing ring 24 to move until the sealing ring 24 is installed in place. Then screw the first connecting sleeve 31 and the second connecting sleeve 51 onto the limiting pipe 12 respectively, which reduces the impact on other components during the replacement process. Using two sealing rings 24 can provide a double sealing effect and reduce the risk of leakage.
[0024] Embodiment 2:
[0025] Please refer to the attached Figure 1 - attached Figure 4, one end of the first connection structure 3 is provided with a water inlet structure 4. The water inlet structure 4 includes a water inlet head 41 and a water inlet pipe 42. The water inlet head 41 and the water inlet pipe 42 are fixedly connected. An internal thread is provided inside the water inlet head 41. The water inlet head 41 is threadedly connected to the first connection sleeve 31. One end of the second connection structure 5 is provided with a water outlet structure 6. The water outlet structure 6 includes a water outlet head 61 and a water outlet pipe 62. The water outlet pipe 62 is fixedly connected to the water outlet head 61. An internal thread is provided inside the water outlet head 61. The water outlet head 61 is threadedly connected to the second connection sleeve 51. Plugging structures 7 are respectively provided inside the water inlet head 41 and the water outlet head 61. The plugging structure 7 includes a fixing frame 71. The fixing frame 71 is fixedly installed inside the first connection sleeve 31 and the second connection sleeve 51 respectively. A guide rod 72 is slidably installed on the fixing frame 71. A floating ball 74 is fixedly installed at one end of the guide rod 72. A spring 73 is sleeved on the guide rod 72. One end of the spring 73 is fixedly connected to the fixing frame 71. The other end of the spring 73 is fixedly connected to the floating ball 74. The diameter of the floating ball 74 is slightly larger than the inner diameters of the water inlet pipe 42 and the water outlet pipe 62. When the sealing ring 24 needs to be disassembled and replaced, when the first connection sleeve 31 and the second connection sleeve 51 are loosened, at this time, the first connection sleeve 31 and the second connection sleeve 51 move in the water inlet head 41 and the water outlet head 61 respectively. At the same time, the fixing frame 71 is driven to move through the first connection sleeve 31 and the second connection sleeve 51. The fixing frame 71 drives the floating ball 74 to move through the guide rod 72 and the spring 73. When the floating ball 74 contacts the water inlet pipe 42 and the water outlet pipe 62, the water inlet pipe 42 and the water outlet pipe 62 are blocked by the floating ball 74, so that the water in the water inlet pipe 42 and the water outlet pipe 62 flows back into the diversion pipe 11 and the limit pipe 12, facilitating the replacement of the sealing ring 24 by the personnel. The floating ball 74 blocks the water inlet pipe 42 and the water outlet pipe 62. The maintenance personnel do not need to additionally close the water source of the entire system, which greatly simplifies the process of disassembling and replacing the sealing ring 24, effectively preventing water leakage during the disassembly process, and reducing the wet working environment and water leakage accidents caused by uncontrolled water flow.
[0026] Working principle of the present utility model: The present utility model is a lightweight heat-insulating diversion pipe. When the first connecting sleeve 31 and the second connecting sleeve 51 are loosened, at this time, the first connecting sleeve 31 and the second connecting sleeve 51 move in the water inlet head 41 and the water outlet head 61 respectively. At the same time, the fixing frame 71 is driven to move through the first connecting sleeve 31 and the second connecting sleeve 51. The fixing frame 71 drives the floating ball 74 to move through the guide rod 72 and the spring 73. When the floating ball 74 contacts the water inlet pipe 42 and the water outlet pipe 62, the water inlet pipe 42 and the water outlet pipe 62 are blocked by the floating ball 74. At this time, the first connecting sleeve 31 and the second connecting sleeve 51 are disengaged from the limit pipe 12, and then the limit pipe 12 is unscrewed from the diversion pipe 11. Since there are two sealing rings 24, the two sealing rings 24 can be removed and replaced respectively. After the sealing ring 24 is replaced again, the limit pipe 12 is screwed into the diversion pipe 11. Because the end of the limit pipe 12 contacts the sealing ring 24, when the limit pipe 12 is screwed into the diversion pipe 11, it will drive the sealing ring 24 to move until the sealing ring 24 is installed in place, and then the first connecting sleeve 31 and the second connecting sleeve 51 are screwed onto the limit pipe 12 respectively.
[0027] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not used to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included in the protection scope of the present utility model.
