Description

Technical Field

[0001] The utility model relates to the technical field of aluminum alloy flanges, in particular to an extruded aluminum alloy flange. Background Art

[0002] Flange, also known as flange flange or flange, is a part that connects shafts to each other and is used for connection between pipe ends. It is also used for flanges on equipment inlets and outlets and is used to connect two devices, such as reducer flanges. Flange connection or flange joint refers to a detachable connection consisting of flanges, gaskets and bolts that are connected to each other as a group of combined sealing structures. Pipe flange refers to the flange used for piping in pipeline installations. It is used on equipment to refer to the inlet and outlet flanges of the equipment. There are holes on the flange, and bolts connect the two flanges tightly. Gaskets are used to seal between the flanges. Flanges are divided into threaded connection (threaded connection) flanges, welding flanges and clamping flanges. Flanges are used in pairs. Threaded flanges can be used for low-pressure pipelines, and welding flanges can be used for pressures above four kilograms. Sealing gaskets are added between the two flange plates and then fastened with bolts. Flanges of different pressures have different thicknesses, and they use different bolts.

[0003] At present, the flanges used in the connection between the muffler and the external pipe of the vortex air pump on the market are all two-legged flanges, that is, they are positioned with two U-shaped holes. If the positioning is inaccurate, it is easy to shake and cause positioning deviation. The shaking is also easy to cause mechanical damage and shorten the service life of the machine.
