Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of pipeline connection, and particularly relates to a flange for pipeline connection with a compression-resistant structure. Background Art
[0002] In modern industrial and civil fields, pipeline systems are widely used. As a key component for pipeline connection, the performance of the flange for pipeline connection directly affects the reliability and safety of the entire pipeline system.
[0003] Currently, traditional pipeline flange connections mainly rely on gaskets to achieve the sealing function. However, in actual use, over time, the gaskets will gradually age. After aging, the gaskets lose their elasticity and cannot effectively fill the gap between the flanges, resulting in leakage problems at the pipeline connection. Such leakage not only causes waste of resources but may also pollute the environment. Even in some specific situations, such as pipeline systems involving flammable, explosive or toxic media, leakage may even trigger serious safety accidents.
[0004] In summary, the existing flanges for pipeline connection have obvious deficiencies in terms of sealing performance, and there is an urgent need for a new type of flange for pipeline connection with a compression-resistant structure to solve these problems. Content of the Utility Model
[0005] The utility model designs a flange for pipeline connection with a compression-resistant structure to solve the above-mentioned existing problems.
[0006] In order to achieve the above technical purposes and reach the above technical effects, the utility model is realized through the following technical solutions:
[0007] A flange for pipeline connection with a compression-resistant structure includes a flange. A clamping groove is formed on the left side wall surface of the flange. A connecting seat is provided on the right side wall of the flange. A groove is formed on the left side wall surface of the connecting seat. A convex seat is provided on the inner wall of the groove. A fixing seat is provided on the right side wall of the connecting seat. A spring is clamped on the outer wall of the convex seat and sleeved on the inner wall of the groove.
[0008] A support plate is embedded in the clamping groove. A connecting plate is provided on the right side wall surface of the support plate. The left end of the spring is clamped on the outer wall of the connecting plate.
[0009] It further includes a gasket. Circular grooves are formed on both the left and right side wall surfaces of the gasket.
[0010] Furthermore, the left end of the convex seat penetrates through the flange and the connecting plate and extends into the support plate.
[0011] Furthermore, the fixing seat, the convex seat, the connecting plate and the support plate are interconnected.
[0012] Furthermore, a plurality of through holes are provided on the outer walls of the flange and the gasket, and they are arranged in opposite positions.
[0013] The beneficial effects of the present utility model are as follows:
[0014] Through a unique design, this new type of flange effectively solves the leakage problem caused by gasket aging. Even when the gasket loses its elasticity after long-term use, it can still maintain a good sealing effect, greatly reducing the risk of resource waste and environmental pollution. At the same time, it also reduces the possibility of safety accidents caused by leakage.
[0015] Adopting a mechanical structure ensures more reliable sealing at the pipe connection, can adapt to various complex working environments and medium conditions, which greatly improves the reliability of the pipeline system, extends the service life of the pipeline, reduces the maintenance cost and downtime of the pipeline system, and improves production efficiency.

[0022] Refer to Figure 1-2As shown in the figure, a flange for pipeline connection with a compressive structure includes a flange 1. A clamping groove 2 is formed on the left wall surface of the flange 1. A connecting seat 3 is provided on the right wall of the flange 1. A groove 4 is formed on the left wall surface of the connecting seat 3. A convex seat 5 is provided on the inner wall of the groove 4. A fixing seat 6 is provided on the right wall of the connecting seat 3. A spring 7 is clamped on the outer wall of the convex seat 5 and sleeved on the inner wall of the groove 4.
[0023] A support plate 8 is embedded in the clamping groove 2. A connecting plate 9 is provided on the right wall surface of the support plate 8. The left end of the spring 7 is clamped on the outer wall of the connecting plate 9.
[0024] It further includes a sealing gasket 10. Circular grooves 11 are formed on both the left and right wall surfaces of the sealing gasket 10.
[0025] Furthermore, the left end of the convex seat 5 penetrates through the flange 1 and the connecting plate 9 and extends into the support plate 8.
[0026] Furthermore, the fixing seat 6, the convex seat 5, the connecting plate 9 and the support plate 8 are connected and communicated with each other.
[0027] Furthermore, a plurality of through holes are formed on the outer walls of the flange 1 and the sealing gasket 10, and the positions are arranged opposite to each other.
[0028] The detailed connection means are well-known technologies in the art. All components in this solution are common standard parts or components known to those skilled in the art.

[0029] A specific application of this embodiment is as follows:
[0030] During use, the pipeline is connected to the outer wall of the fixing seat 6 by interference fit or welding. The flanges 1 on the two pipelines are butted against each other, and the sealing gasket 10 is placed in the middle part. The part of the support plate 8 protruding outside the flange 1 is placed in the circular groove 11. When the two flanges 1 are butted and fixed, the two support plates 8 are squeezed into the circular groove 11, and the spring 7 is compressed outward. The spring 7 gives a reverse thrust to the support plate 8 and the connecting plate 9. When the sealing gasket 10 loses elasticity and ages and becomes thinner, the elastic force of the spring 7 pushes the two support plates 8 to tightly squeeze in the circular groove 11, preventing a gap from being generated between the support plate 8 and the sealing gasket 10, thereby improving the sealing performance between the two flanges 1.
