Description

Technical Field

[0001] The utility model relates to the technical field of flanges, and more specifically to a flange plate which is easy to position. Background Art

[0002] Flange is an important part for connecting pipes to each other and is used to connect pipe ends. At present, most of the connecting flanges on the market are made of two flat flanges plus a gasket, and then the screws are tightened. When tightening the screws, you need to align the two flanges by hand first, and then tighten the screws. The operation is inconvenient, and it is very easy to cause the two flanges to be misaligned, resulting in gaps in the connection between the flanges, resulting in poor sealing performance. Therefore, in order to solve these problems, we propose a flange that is easy to position to solve the problem.

[0003] In the prior art, a patent document with publication number CN219432701U provides a flange that is easy to position. The flange that is easy to position is butt-jointed by a butt joint with an outer ring, and is positioned by butt joint protrusions and grooves.

[0004] Although the flange that is easy to position has many beneficial effects, it still has the following problems: the flange that is easy to position has a single external structure and no structure to protect the flange. The flange is easily damaged and the protection effect of the device is poor, which needs to be improved; secondly, the flange that is easy to position is connected by a butt joint, and then the butt bump and groove are used for positioning. It is necessary to first connect the butt joints of the two flanges, and then rotate the flange to fit the butt bump into the groove. It is not easy to directly embed the butt bump into the groove, and the positioning effect is poor. Therefore, a flange that is easy to position is proposed to address the above problems.
