Description

Technical Field

[0001] This utility model relates to the field of flange fastening technology, specifically a flange self-locking fastening structure. Background Technology

[0002] A flange is a part used to connect shafts to each other, for connecting pipe ends, and also for connecting two pieces of equipment at the inlet and outlet. A flange is usually a disc-shaped metal body with several holes around its perimeter for fixing, used to connect other things.

[0003] Existing technologies, such as CN214274804U, describe a self-locking flange. This utility model's self-locking flange allows the flange to be installed and fixed on the pipeline using a locking block and flange plate. No welding is required. After pumping, purging, or other operations are completed, the flange can be removed by simply removing the locking block. This simplifies operation, improves work efficiency, and does not damage the pipeline structure. Furthermore, it can be reused after removal.

[0004] However, this flange still has some shortcomings in its use:

[0005] 1. The flange has poor sealing performance because the connection between the locking block and the flange is not tight enough, which can easily lead to leakage during use. This not only affects the normal operation of the equipment, but may also pose a safety hazard.

[0006] 2. Under high pressure or high temperature conditions, slight displacement may occur in the connection between the locking block and the flange, resulting in a decrease in sealing performance. When subjected to external forces for a long time, it is prone to breakage or deformation, thereby affecting the stability and service life of the flange. Utility Model Content
