Description

Technical Field

[0001] This utility model relates to the field of flange structure technology, and in particular to a flange structure that can be loaded in multiple stages. Background Technology

[0002] Flanges, as a common connecting element, are typically used to connect the ends of pipes. Multi-stage flange structures can provide more flexible and adjustable connection solutions, suitable for piping systems under different pressures, temperatures, and operating environments. Multi-stage flange structures usually employ multiple sealing designs, allowing the flange to withstand pressure in stages under different loads, which typically enhances pressure resistance. By distributing pressure, the flange can be used under higher pressures and is less prone to damage.

[0003] When the operating pressure of the pipeline exceeds the flange's bearing capacity, the flange's sealing surface will be compressed, deformed, and broken. The flange structure is equipped with gaskets, which lose their elasticity when compressed, thus affecting the sealing performance. Therefore, it is particularly important to design a flange structure that can be loaded in multiple stages. Utility Model Content

[0004] The purpose of this invention is to provide a flange structure that can be loaded in multiple stages, in order to solve the problem mentioned in the background art that the flange structure is equipped with a gasket, and the gasket loses its elasticity after being compressed, thereby affecting the sealing performance.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1-4 This utility model provides a technical solution for a flange structure capable of multi-stage loading:

[0022] Example 1:

[0023] like Figure 1-3 As shown, a multi-stage loading flange structure includes a pressure plate 1, positioning blocks 2 on both sides of the pressure plate 1, a first flange 3 on the top of the pressure plate 1, arc-shaped blocks 4 on both sides of the first flange 3, a first gasket 7 on the top of the first flange 3, abutment rods 5 on the top of the two arc-shaped blocks 4, a reinforcing ring 10 on the top of the first gasket 7, a flange ring 6 at the bottom of the reinforcing ring 10, a second gasket 12 on the top of the reinforcing ring 10, and a second flange 13 on the top of the reinforcing ring 10. The second gasket 12 is located between the reinforcing ring 10 and the second flange 13, providing a seal to prevent fluid leakage. The first gasket 7 is located between the first flange 3 and the flange ring 6, further enhancing the sealing performance of the flange structure. The combined use of the flange ring 6, the reinforcing ring 10, and the second flange 13 achieves the purpose of multi-stage loading and improves the robustness of the flange structure for pipeline connections.

[0024] Example 2:

[0025] Based on Example 1, such as Figure 1 and Figure 4As shown, L-shaped blocks 9 are fixedly installed on both sides of the reinforcing ring 10. One end of each of the two abutting rods 5 is fixedly connected to the top of the two arc-shaped blocks 4. Auxiliary rods 8 are fixedly installed at the bottom of each of the two L-shaped blocks 9. One end of each of the two auxiliary rods 8 is fixedly connected to the other end of each of the two abutting rods 5. The reinforcing ring 10 and the first flange 3 are fixed together by the two abutting rods 5 and the two auxiliary rods 8, thereby enhancing the stability of the reinforcing ring 10. After one end of the limiting bolt 14 is inserted into the threaded hole 11, the two are threadedly connected.

[0026] Working Principle: Flanges, as common connecting elements, are typically used to connect the ends of pipes. Multi-stage loading flange structures offer more flexible and adjustable connection options, suitable for piping systems under different pressures, temperatures, and operating environments. Multi-stage loading flange structures usually employ multiple sealing designs, allowing the flange to withstand pressure in stages under different loads, typically enhancing pressure resistance. By distributing pressure, the flange can be used at higher pressures without easily being damaged. When the operating pressure of the pipeline exceeds the flange's capacity, the flange sealing surface will be compressed, deformed, and fractured. The flange structure includes gaskets; when compressed, the gaskets lose elasticity, thus affecting sealing performance. Therefore, designing a multi-stage loading flange structure is particularly important. The bottom of the second flange 13 and the top of the reinforcing ring 10... The components fit together, and the pipe is inserted into the interior of the second flange 13 and the first flange 3 to achieve combination. The second gasket 12 is located between the reinforcing ring 10 and the second flange 13, which plays a sealing role to prevent fluid leakage. The first gasket 7 is located between the first flange 3 and the flange ring 6, which further enhances the sealing performance of the flange structure. The combined use of the flange ring 6, the reinforcing ring 10 and the second flange 13 achieves the purpose of multi-stage loading and improves the firmness of the flange structure for pipe connection. The reinforcing ring 10 and the first flange 3 are fixed by two abutment rods 5 and two auxiliary rods 8, thereby enhancing the stability of the reinforcing ring 10. After one end of the limiting bolt 14 is embedded into the threaded hole 11, the two are threadedly connected, so the reinforcing ring 10 and the second flange 13 can be limited and fixed.
