Description

Technical Field

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

[0002] Flange is also called flange or flange. Flange is a part that connects pipes to each other and valves to each other. Flanges are generally used in pairs. A pair of flanges are set with corresponding mounting holes, and the pipelines are well connected by passing bolts and other connectors through the mounting holes. However, the existing technology has a strict limit on the thickness of the flange as a whole, and it is impossible to adjust the flange thickness according to the site requirements.

[0003] Application number "CN201320450358.5" records "a flange, including a first flange and a second flange, each of which is provided with corresponding mounting holes, and bolts are screwed and connected with nuts through the mounting holes on the first flange and the mounting holes on the second flange, characterized in that a circle of raised sealing gaskets are provided around the mounting holes on both sides of the first flange; a circle of grooves matching the raised sealing gaskets are provided around the mounting holes on one side of the second flange that contacts the first flange, and a circle of raised sealing gaskets are provided around the mounting holes on the other side. There are 2-10 mounting holes on the first flange and the second flange."

[0004] The above patent is based on flanges, and a circle of raised gaskets are arranged around the mounting holes on both sides of the first flange; a circle of grooves matching the raised gaskets are arranged around the mounting holes on one side of the second flange that contacts the first flange, and a circle of raised gaskets are arranged around the mounting holes on the other side. In specific use, when the first flange and the second flange are used in conjunction, the raised gasket on the first flange is inserted into a circle of grooves matching the raised gasket on the first flange, and at the same time, the other side of the junction between the first flange and the second flange is a raised gasket, so that the bolts and nuts are tightly pressed against the gaskets, which often effectively avoids water leakage into the mounting holes during use, prevents the bolts from oxidizing and rusting, and even prevents the bolts from being unable to be removed from the mounting holes, facilitating subsequent maintenance of the pipeline.

[0005] The above patent structure is reasonable and simple, and easy to manufacture. In actual use, it often effectively prevents water from leaking into the mounting hole, prevents the bolts from oxidizing and rusting, and even prevents the bolts from being removed from the mounting hole. However, the overall thickness of the above flange is relatively restricted, and the thickness of the flange cannot be adjusted according to the thickness requirements on site, resulting in greater limitations on the overall flange.
