Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of flanges, and specifically relates to a high-strength high-neck aluminum flange structure. Background Technique
[0002] In the field of pipeline connection, the flange structure is one of the commonly used connection methods. Especially in industrial environments with high pressure and high temperature, stricter requirements are imposed on the strength and sealing performance of flanges. Traditional flange structures are mostly made of steel. Although they have high strength, they are heavy, costly, and may have corrosion problems in certain specific environments (such as chemical industry, food, etc.). Therefore, aluminum flanges have gradually gained favor due to their advantages such as light weight, corrosion resistance, and good thermal conductivity. However, the strength of aluminum materials is relatively low. Especially in the design of high-neck flanges, how to ensure both the strength and sealing performance of the flanges has become a technical problem.
[0003] Existing aluminum high-neck flange structures often have deficiencies in sealing performance. Especially at the pipeline connection, due to the tiny gaps between the pipeline and the flange, it is easy to cause medium leakage. In addition, traditional sealing methods such as gasket sealing are prone to failure during long-term use or under large pressure, affecting the stability and safety of the connection. Content of the Utility Model
[0004] The purpose of the utility model is to provide a high-strength high-neck aluminum flange structure to solve the problems raised in the above background technique.
[0005] To achieve the above purpose, the utility model provides the following technical solution: A high-strength high-neck aluminum flange structure, including a high-strength high-neck aluminum flange plate. Bolt holes are provided on the surface of the high-strength high-neck aluminum flange plate. A sealing sleeve is sleeved outside the pipe body of the high-strength high-neck aluminum flange plate. A rubber gasket is provided on the outer ring surface of the sealing sleeve. A rubber plug ring is provided on the surface of the rubber gasket. One end of the rubber plug ring is inserted into the bolt hole.
[0006] Preferably, the bolt holes are in a round hole structure. There are multiple bolt holes, and the multiple bolt holes are arranged in a circular pattern at equal distances and of equal size.
[0007] Preferably, the sealing sleeve is in a "T"-shaped round pipe structure. One end plate surface of the sealing sleeve leans against one side of the plate body of the high-strength high-neck aluminum flange plate.
[0008] Preferably, an arc-shaped groove is provided on the outer ring surface of the sealing sleeve. The arc-shaped groove and the bolt holes correspond one by one. The rubber gasket is integrally formed on the surface of the arc-shaped groove.
[0009] Preferably, the rubber gasket is in the shape of an annular plate. The inner diameter of the rubber gasket is smaller than the diameter of the bolt hole. A picking groove is formed on the side of the rubber gasket away from the sealing sleeve, and the picking groove faces the end plate of the high-strength high-neck aluminum flange.
[0010] Preferably, the rubber plug ring is integrally formed in the inner ring of the rubber gasket. The outer diameter of the rubber plug ring is equal to the diameter of the bolt hole, and the tube length of the rubber plug ring is smaller than the depth of the bolt hole.
[0011] Compared with the prior art, the beneficial effects of the present utility model are as follows:
[0012] For the high-strength high-neck aluminum flange structure proposed by the present utility model, by sleeving a sealing sleeve on the outer side of the flange coil body and using the part of the sealing sleeve extending into the pipeline to be clamped between the flange coil body and the inner wall of the pipeline, the gap between the pipeline and the flange is effectively reduced, and the sealing performance of the connection is significantly improved. At the same time, the end plate of the sealing sleeve is also clamped between the end plate of the flange and the pipeline, further enhancing the sealing effect.
[0013] The design of the sealing sleeve not only improves the sealing performance, but also increases the contact area between the flange and the pipeline through its "T" - shaped structure, enhancing the stability of the connection. In addition, the design of the rubber gasket and the rubber plug ring enables more effective prevention of screw loosening after the bolts are tightened, ensuring the long-term stability of the connection.

The sealing sleeve 3 is in a "T"-shaped round pipe structure, and one end plate surface of the sealing sleeve 3 abuts against one side of the plate body of the high-strength high-neck aluminum flange plate 1. The reason for sleeving the sealing sleeve 3 on the pipe body of the high-strength high-neck aluminum flange plate 1 is that after the pipe body of the high-strength high-neck aluminum flange plate 1 is inserted into the end of the pipeline, the part of the sealing sleeve 3 extending into the pipeline is clamped between the pipe body of the high-strength high-neck aluminum flange plate 1 and the inner wall of the pipeline, improving the sealing performance of the connection between the high-strength high-neck aluminum flange plate 1 and the pipeline. Moreover, the end plate body of the sealing sleeve 3 is clamped between the end plate body of the high-strength high-neck aluminum flange plate 1 and the pipeline, improving the sealing performance after the connection between the high-strength high-neck aluminum flange plate 1 and the pipeline.
[0023] A rubber gasket 5 is provided on the outer ring surface of the sealing sleeve 3. A notch 4 is provided on the outer ring surface of the sealing sleeve 3. The notch 4 is in an arc-shaped groove. The notch 4 corresponds to the bolt hole 2 one by one. The rubber gasket 5 is integrally formed on the surface of the notch 4. The rubber gasket 5 is in a circular ring plate structure. The inner ring diameter of the rubber gasket 5 is smaller than the aperture of the bolt hole 2. A picking groove 7 is provided on the side of the rubber gasket 5 away from the sealing sleeve 3. The picking groove 7 faces the end plate body of the high-strength high-neck aluminum flange plate 1. A rubber plug ring 6 is provided on the surface of the rubber gasket 5. One end of the rubber plug ring 6 is inserted into the bolt hole 2. The rubber plug ring 6 is integrally formed in the inner ring mouth of the rubber gasket 5. The outer diameter of the rubber plug ring 6 is equal to the aperture of the bolt hole 2. The pipe length of the rubber plug ring 6 is smaller than the depth of the bolt hole 2.
[0024] During use, the reason for integrally forming the rubber gasket 5 and the rubber plug ring 6 on the outer ring of the sealing sleeve 3 is that when the bolt passes through the bolt hole 2 and is tightened, the rubber gasket 5 is clamped between the nut and the high-strength high-neck aluminum flange plate 1 to act as a gasket, and the rubber plug ring 6 is clamped between the bolt hole 2 and the screw rod to prevent the screw rod from loosening.
