Description

Technical Field

[0001] The utility model relates to the technical field of high-pressure fluid connectors, and specifically provides a high-strength connector for high-pressure fluids. Background Technique

[0002] High-pressure fluid refers to a fluid with a pressure exceeding a certain limit, such as substances in high-pressure oil cylinders and high-pressure pipelines. Under high-pressure conditions, physical properties such as density, viscosity, and temperature of these fluids will change, and the movement speed and flow rate are also relatively large. High-pressure fluid technology is to apply high pressure to the fluid to change its physical and chemical properties or discover new physical and chemical behaviors. For example, adding oil and water to a high-pressure reactor, under high pressure, they will be compressed and mixed to form an emulsion system, achieving some special physical and chemical changes. This technology is widely used in fields such as oil, cosmetics, food, and biotechnology. In a high-pressure fluid system, special components such as high-strength connectors play a crucial role. They are not only used to connect pipelines and equipment but also undertake important functions such as preventing fluid leakage and maintaining the stability of the system pressure.

[0003] Moreover, in the application document with the publication number CN216715478U, a buckle assembly and a high-pressure pipe connection structure are mentioned. In this structure, two high-pressure pipes are connected by a union joint. One buckle assembly is fixed on the periphery of one high-pressure pipe, and the other buckle assembly is fixed on the periphery of the other high-pressure pipe. The connecting parts fixed on different pipe bodies can be connected by a locking piece. The above-mentioned buckle assembly can lock the two connected pipe bodies; prevent the high-pressure pipe from detaching from the union joint during operation and prevent the high-pressure pipe from flying out under the impact of high-pressure fluid, thus avoiding potential safety hazards. However, there are still certain defects that need to be optimized. The specific defects are as follows: The buffer pad in this structure is relatively difficult to replace when it is worn later, and the connection can be more stable.

[0004] Therefore, it is particularly important to design a high-strength connector for high-pressure fluids to change the above technical defects and improve the overall practicality. Content of the Utility Model
