Description

Technical Field

[0001] The utility model relates to the technical field of hardware forgings, in particular to a hardware forging with high anti-rust performance. Background Art

[0002] Flange, also known as flange flange or flange, basically refers to the protruding structure on an object, or an object with a protruding structure, such as flange bolts, flange shafts, etc. Since flange structures are often used for connections between shafts, between pipe ends, or between equipment, the flange usually refers to a part or structure used for connection in the mechanical field, such as pipe flanges and reducer flanges. Flange connection refers to a mechanical connection method in which a gasket is placed between the flange plates and then tightened and sealed with several bolts. It is commonly used for steel pipes, cast iron pipes, plastic pipes, and other pipe sections that need to be disassembled frequently, as well as larger diameter pipe connections. In order to prevent corrosion and increase sealing, an inner lining layer is often set in the inner cavity of the flange.

[0003] For example, the Chinese utility model provides "a corrosion-resistant flange", and its announcement number is: CN214947120U, which includes a flange assembly body. The flange assembly body is installed at one end of the pipe that needs to be docked, and the bolts pass through the connecting cylinder and cooperate with the nuts to fix the flange assembly body. In the process of docking and fixing the flange assembly body, the external barrier ring will be embedded in the inner cavity of the external barrier groove to prevent the invasion of external moisture into the flange assembly body. The internal infiltration barrier ring will be embedded in the inner cavity of the internal infiltration barrier groove to prevent leakage between the connected pipes. The corrosive liquid penetrates into the interior of the flange assembly body and causes damage to the flange assembly body. When the flange assembly body cooperates with the first protective cover and the second protective cover to be installed at one end of the pipe, a cavity is formed between the internal infiltration flow groove and the pipe. If leakage occurs between the connected pipes, it can be discovered in time.

[0004] In the process of realizing the utility model, the inventors found that there are at least the following problems in this technology: the hardware forgings in the above patent lack effective wear-resistant structures during use, resulting in poor wear resistance of the surface; and at the same time, they do not have an inner lining structure, and cannot further improve the sealing effect of the flange forgings. For this reason, we propose a hardware forging with high anti-rust performance. Utility Model Content
