Description

Technical Field

[0001] The utility model belongs to the technical field of pipeline connection, in particular to a flange, and relates to a stainless steel flange. Background Art

[0002] Flange, also known as flange, is just a general term. It usually refers to a disc-shaped metal body with several fixed holes around it for connecting other things. It is widely used in pipeline projects. Because of their strange appearances, as long as they look like them, they are called flanges. Flanges can connect pipes and pipes, be fixed at the ports of pipes, and can seal the connection between pipes.

[0003] The patent application with publication number CN216520142U discloses a stainless steel flange. The stainless steel flange, through the design of a connecting and fixing component and an auxiliary mechanism, after the sealing ring is inserted into the annular outer groove from one end of the neck tube, the staff can simultaneously press the two arc-shaped positioning plates in the connecting and fixing component inwardly. After the two arc-shaped positioning plates are pressed to a certain position, the staff can insert the connecting head and the annular connecting boss into the neck tube, and then use the sleeves between the two arc-shaped positioning plates and the annular positioning grooves and the annular protrusions and the annular inner grooves to achieve the connection and fixation between the flange body and the neck tube. When disassembling again, the staff can also directly use the ejector rod in the auxiliary mechanism to eject the two arc-shaped positioning plates from the annular positioning grooves, and then pull the flange body outward to achieve the separation between the flange body and the neck tube. Compared with the traditional method, the space occupied during the flange transportation process is reduced, the convenience of flange transportation is improved, and the convenience of replacing flange parts is correspondingly improved.

[0004] The above-mentioned comparative document uses two pieces as the majority, which requires more materials to produce and will result in higher manufacturing costs. In addition, different holes are provided on the two pieces, which may easily lead to poor sealing when used.

[0005] In summary, the utility model provides a stainless steel flange to solve the above problems. Utility Model Content
