They are key components to ensure the stability and safety of fluid transmission.

[0003] Specifically, aluminum flanges are mainly used for connecting pipelines in pipeline engineering. They can achieve connections with different pipe diameters and pressure levels, and have the advantages of simple structure and easy installation. At the same time, aluminum flanges are also suitable for connecting and fixing various containers, such as storage tanks, reactors, etc. Their good corrosion resistance allows them to be used for a long time in harsh environments.

[0004] In the process of implementing the solution, the inventors found that the following problems in the prior art have not been well solved: traditional aluminum flanges are usually connected by bolt assemblies, and the number of bolts is large. The bolt assemblies need to be calibrated multiple times during installation. After long-term use, the bolt and nut connections are exposed to the outside and eroded by wind and rain, and are easily difficult to disassemble after rusting. For this, rust removers are needed, and even cutting equipment is needed to cut them off. In summary, traditional aluminum flanges assembled by bolt assemblies are troublesome to install and inconvenient to disassemble after rusting. Utility Model Content

[0026] Specifically, the main plug-in blocks 11 are respectively inserted into the interior of the main slots 21, and the outer diameters of the main plug-in blocks 11 match the inner diameters of the main slots 21, and the ends of the outer plug-in blocks 14 away from the inner plug-in blocks 13 are respectively connected to the through-cavities 17, and the ends of the outer plug-in blocks 14 passing through the through-cavities 17 are respectively inserted into the interior of the auxiliary slots 22 and contact the side close to the inner plug-in block 26, and the outer diameters of the outer plug-in blocks 14 match the inner diameters of the through-cavities 17 and the auxiliary slots 22, so that the flange 1 1 and the flange 2 2 have the technical effect of convenient installation and disassembly.

[0027] Specifically, the outer diameter of the inner block 26 matches the inner diameter of the auxiliary slot 22, the outer diameter of the outer block 27 matches the inner diameter of the outer slot 23, the inner block 26 is integral with the outer block 27 and the outer blocking ring 28, and the inner block 26, the outer block 27 and the outer blocking ring 28 are all made of butyl rubber, the outer dimensions of the outer blocking ring 28 match the inner dimensions of the annular groove 1 24, and the outer dimensions of the annular protrusion 25 match the inner dimensions of the annular groove 29, which can better seal the auxiliary slot 22 and the outer slot 23 to prevent the penetration of rainwater and humid gas.

[0028] Specifically, one end of the inner plug-in block 13 away from the outer plug-in block 14 is in contact with the spring 16, and the external thread teeth 19 on the outer wall of the inner plug-in block 13 are threadedly connected with the internal thread 18 in the inner receiving groove 12. When disassembling, the inner plug-in block 13 is pushed deep into the inner receiving groove 12, and through the threaded connection of the external thread teeth 19 and the internal thread 18, the external plug-in block 14 can be stably received inside the outer plug-in block 14, so that it is convenient to be pulled out from the main slot 21 later.

[0029] Working principle:

[0030] After the flange 1 and the flange 2 are fitted together, the main plug-in block 11 will be inserted into the main slot 21, and the inner plug-in block 13 will drive the outer plug-in block 14 to be pushed out from the position of the through cavity 17 through the spring 16, so as to be inserted into the auxiliary slot 22 of the main slot 21. By inserting the main plug-in block 11 into the main slot 21 and the outer plug-in block 14 into the auxiliary slot 22, not only the flange 1 and the flange 2 are conveniently assembled, but also a good anti-rotation effect is achieved, which avoids the traditional bolt assembly connection method that is easy to cause the thread to be withdrawn under vibration. In the case of a gap at the connection between flange 1 and flange 2, the inner block 26 is inserted into the auxiliary slot 22 after passing through the outer slot 23, and its inserted end contacts the end of the outer plug-in block 14 away from the inner plug-in block 13, while the outer block 27 is inserted into the outer slot 23. The inner block 26 and the outer block 27 can block the auxiliary slot 22 and the outer slot 23 to prevent the problem of corrosion caused by the entry of rainwater from the outside and the difficulty in disassembly. After the outer block 27 is inserted into the outer slot 23, the outer blocking ring 28 is embedded in the annular groove 24, and the annular convex The block 25 will be embedded in the inside of the annular groove 29, which increases the sealing. Even if moist air penetrates into the auxiliary slot 22, since the external plug-in block 14 used for limiting and the auxiliary slot 22 are only connected through an interlaced relationship, the external plug-in block 14 can be easily hammered from the auxiliary slot 22 into the through cavity 17 by tapping a screwdriver. Compared with the disassembly method after the bolt is rusted, it also has the effect of convenient disassembly. When disassembling, you only need to pull out the external block 27 and the internal block 26 from the external slot 23 and the auxiliary slot 22, and use a flat screw to The screwdriver is inserted into the slot 15 and pressed down, so that the outer plug-in block 14 can be pushed from the auxiliary slot 22 into the interior of the through cavity 17, and the inner plug-in block 13 will also follow the downward movement, and the inner plug-in block 13 is driven to rotate by rotating the screwdriver, so that the outer thread 19 on the outer wall is threadedly connected with the inner thread 18 on the inner wall of the inner receiving groove 12, so that the outer plug-in block 14 can be stably located in the through cavity 17, and then the flange 1 and the flange 2 are horizontally separated, so that the main plug-in block 11 can be driven to be pulled out from the main slot 21, thereby achieving the effect of convenient disassembly.
