Description

Technical Field

[0001] The utility model relates to the technical field of flange connection, and specifically relates to a quick-docking flange. Background Technique

[0002] In many industrial scenarios, such as in the pipeline systems of industries like chemical engineering, food and beverage processing, and pharmaceuticals, operations such as connecting, disassembling, maintaining, overhauling, and replacing pipelines and related equipment are often required. Flange connection is an important connection method in pipeline construction. This connection method has the advantages of being easy to disassemble, having high strength, and good sealing performance. Currently, the commonly used connection method is bolted flange connection;

[0003] After retrieval, the Chinese patent utility model patent with the publication number: CN205781559U discloses a quick-docking device for flanges, which is suitable for the repeated disassembly of flange connections. The patent records that it specifically includes a front clamp and a rear clamp for clamping the flange, an adjusting bolt, an adjusting nut, a locking bolt, and a locking nut for connecting the front and rear clamps. The adjusting bolt is hinged to the front clamp and is locked by the adjusting nut after passing through the positioning hole on the rear clamp. The locking bolt is hinged to the rear clamp and is adjusted by the locking nut after passing through the adjusting hole on the front clamp. The inner sides of the front and rear clamps are designed with a groove structure for clamping the flange. A locking groove is opened at the front clamp for setting the clamping force of the locking nut. The front clamp is provided with a break point. After the locking nut leaves the adjusting groove, the locking bolt can be directly peeled off from the front clamp without completely loosening and taking it out. At the same time, a handle is provided on the front clamp for quickly opening the clamp. The utility model (publication number: CN205781559U) has a simple structure, reliable connection, and a wide range of applications, and can be applied to technical solutions in experimental operations and flange connection operations with quick-opening requirements;

[0004] However, the solution with the publication number: CN205781559U has the technical problem of lacking a sealing component. When the pipeline transports media such as liquids or gases, the absence of a sealing component may cause the medium to leak from the flange connection, resulting in waste of resources, environmental pollution, and even potential safety accidents. And the leakage will cause the pressure inside the pipeline to drop, affecting the normal operation and working efficiency of the system. At the same time, the leaked medium may corrode and damage the surrounding equipment, pipelines, and structures, increasing the maintenance cost and shortening the service life of the equipment. To solve this technical problem, the utility model proposes a quick-docking flange. Summary of the Invention
