Description

Technical Field

[0001] The utility model relates to the field of flanges, in particular to a flange with high pressure resistance. Background Art

[0002] In the field of mechanical connection, flanges are an important connection component and are widely used in the connection between pipes, valves, pumps and other equipment. Although the overall pressure resistance of traditional flanges is taken into consideration during design, in actual use, especially under high pressure and high vibration environments, the bolt holes on the flanges often become weak links. Due to the stress concentration of the material around the bolt holes, long-term exposure to high pressure and vibration may cause the bolt holes to deform or even rupture, thus affecting the stability and safety of the entire connection system.

[0003] In addition, after the traditional flange is tightened with bolts, the gap or loose fit between the bolts and the flange holes can easily cause the bolts to loosen due to external environment (such as temperature changes, mechanical vibrations, etc.), which not only affects the tightness of the connection, but may also cause safety problems such as leakage. Utility Model Content

[0004] The purpose of the utility model is to provide a flange with high pressure resistance to solve the problems raised in the above background technology.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a flange with high pressure resistance, including a high-strength flange body, a plurality of bolt holes are opened on the surface of the high-strength flange body, a steel sleeve is inserted and fixed inside the bolt hole, and is used to be sleeved between the bolt and the bolt hole, a rubber clamp is inserted and fixed on the surface of the steel sleeve, the rubber clamp is integrally formed on the surface of the rubber sleeve, and the rubber sleeve is sleeved and fixed on the end of the steel sleeve.

[0006] Preferably, the steel sleeve is an I-shaped circular tube structure, and two parallel plates of the steel sleeve are respectively distributed on both sides of the high-strength flange body, and the outer diameter of the end plate of the steel sleeve is larger than the hole diameter of the bolt hole.

[0007] Preferably, a plurality of embedding grooves are provided at both ends of the steel sleeve, the rubber clamps correspond to the embedding grooves one by one, the long side length of the rubber clamps is smaller than the depth of the embedding grooves, and the thickness of the rubber clamps is greater than the height of the embedding grooves.

[0008] Preferably, the rubber sleeve is an "L"-shaped circular ring plate, and the inner ring diameter of the rubber sleeve is smaller than the inner ring diameter of the steel sleeve.

[0009] Preferably, the inner wall of the steel sleeve is integrally formed with reinforcing ribs, a plurality of reinforcing ribs are provided, the plurality of reinforcing ribs are arranged side by side, and the plurality of reinforcing ribs are located between the two groups of embedding grooves.

[0010] Compared with the prior art, the beneficial effects of the utility model are:

[0011] The high-pressure-resistant flange proposed in the utility model significantly improves the compressive strength of the bolt hole by adding a steel sleeve of an "I"-shaped circular tube structure inside the bolt hole and combining it with a reinforcing rib design. The steel sleeve and its reinforcing ribs form a solid supporting skeleton, which effectively prevents the deformation of the bolt hole under high pressure and ensures the overall stability and safety of the flange; the rubber clamping strip arranged on the surface of the steel sleeve can be clamped between the bolt and the steel sleeve after the bolt is inserted, and a certain pre-tightening force is generated through deformation, which effectively reduces the risk of loosening of the bolt due to environmental vibration. This design improves the reliability of the connection and reduces the safety hazards caused by loose bolts; the design of the rubber sleeve is not only convenient for the installation of the rubber clamping strip, but also can be filled between the steel sleeve and the bolt structure as an elastic gasket after the bolt is tightened, further enhancing the sealing of the connection. This design helps to prevent medium leakage and improves the overall performance of the connection system. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] In order to make the purpose and technical solution of the utility model clearly and completely described, and the advantages more clearly understood, the embodiments of the utility model are further described in detail in conjunction with the accompanying drawings. It should be understood that the specific embodiments described here are part of the embodiments of the utility model, not all of the embodiments, and are only used to explain the embodiments of the utility model, and are not used to limit the embodiments of the utility model. All other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] See also Figure 1-Figure 7 The utility model provides a technical solution: a flange with high pressure resistance, including a high-strength flange body 1, a plurality of bolt holes 2 are opened on the surface of the high-strength flange body 1, a steel sleeve 3 is inserted and fixed inside the bolt hole 2, and is used to be sleeved between the bolt and the bolt hole 2, the steel sleeve 3 is an "I"-shaped circular tube structure, and two parallel plates of the steel sleeve 3 are respectively distributed on both sides of the high-strength flange body 1, and the outer diameter of the end plate body of the steel sleeve 3 is larger than the hole diameter of the bolt hole 2; the inner wall of the steel sleeve 3 is integrally formed with a reinforcing rib 4, and a plurality of reinforcing ribs 4 are provided, and the plurality of reinforcing ribs 4 are arranged side by side, and the plurality of reinforcing ribs 4 are located between two groups of embedded grooves 5; the reason why the steel sleeve 3 is added inside the bolt hole 2 is to improve the compressive strength at the bolt hole 2, and while the high-strength flange body 1 itself meets the high pressure resistance, the bolt hole 2 is prevented from being squeezed and deformed, that is, the steel sleeve 3 is supported in the bolt hole 2, and cooperates with the reinforcing rib 4 to form a supporting skeleton for the bolt hole 2.

[0022] A rubber clamp 6 is inserted and fixed on the surface of the steel sleeve 3. A plurality of embedding grooves 5 are provided at both ends of the steel sleeve 3. The rubber clamp 6 corresponds to the embedding grooves 5 one by one. The long side length of the rubber clamp 6 is less than the depth of the embedding groove 5, and the thickness of the rubber clamp 6 is greater than the height of the embedding groove 5. The reason why the rubber clamp 6 is added to the surface of the steel sleeve 3 and the rubber clamp 6 protrudes into the inner ring of the steel sleeve 3 is that when the bolts fixing the high-strength flange body 1 are inserted into the steel sleeve 3, the rubber clamp 6 is clamped between the bolts and the steel sleeve 3 to produce deformation. At this time, there will be no shaking between the bolts and the steel sleeve 3, that is, the loosening problem caused by the vibration of the surrounding environment after the bolts are tightened is reduced.

[0023] The rubber clamp strip 6 is integrally formed on the surface of the rubber sleeve 7, and the rubber sleeve 7 is fixed on the end of the steel sleeve 3. The rubber sleeve 7 is an "L"-shaped circular ring plate, and the inner ring diameter of the rubber sleeve 7 is smaller than the inner ring diameter of the steel sleeve 3. The reason why the rubber clamp strip 6 is fixed on the surface of the rubber sleeve 7 is not only to facilitate multiple rubber clamp strips 6 to extend into the corresponding embedding groove 5 together, but also after the rubber sleeve 7 is sleeved on the end of the steel sleeve 3, after the bolt is tightened, the rubber sleeve 7 is squeezed between the steel sleeve 3 and the bolt structure to act as an elastic gasket.

[0024] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
