Technical Field

[0001] The utility model relates to the technical field of flanges, in particular to a large-diameter perforated reinforced aluminum flange. Background Technique

[0002] In industrial production, aluminum flanges are widely used in the connection of equipment such as pipelines and valves due to their light weight, corrosion resistance, easy processing and other characteristics. However, with the continuous expansion of the application field and the increasingly complex working conditions, higher requirements are put forward for the connection strength and sealing performance of aluminum flanges. Especially in large-diameter perforated aluminum flanges, due to the large diameter of the flange holes, problems such as loosening and falling off are likely to occur during bolt connection, seriously affecting the safe operation of the equipment.

[0003] The traditional large-diameter perforated aluminum flanges have the following deficiencies in reinforcement and sealing:

[0004] Poor bolt anti-loosening effect: Due to the large diameter of the flange holes, the bolts are prone to loosen or fall off in the holes under the action of external forces, resulting in connection failure.

[0005] Poor sealing performance: There are often gaps between the bolts and the flange holes, and it is difficult to achieve good sealing effects. Especially in environments with high pressure, high temperature or corrosive media, leakage is likely to occur.

[0006] Complex installation and maintenance: Traditional reinforcement methods often require additional fasteners or sealing materials, increasing the complexity and cost of installation and maintenance.

[0007] Therefore, how to improve the bolt anti-loosening effect and sealing performance of large-diameter perforated aluminum flanges has become an urgent problem to be solved. Content of the Utility Model

[0011] Preferably, the width of the plate body of the plastic strip is greater than the width of the slot opening at the end of the slot away from the bolt hole.

[0012] Preferably, the surface of the elastic traction sheet is provided with an oblong hole, and the connecting surface of the elastic traction sheet and the plastic plug ring is a circular arc curved surface.
