Description

Technical Field

[0001] The utility model relates to the technical field of flanges, in particular to a threaded conversion 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 useful 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 composed of flanges, gaskets and bolts connected to each other as a combined sealing structure. Pipe flange refers to the flange used for piping in pipeline installations. It refers to the inlet and outlet flanges of the equipment used on 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. Most of the threaded conversion flanges on the traditional market are easily affected by vibration during installation, which causes the nut to slip, making the fixed structure position prone to loosening, and thus cannot meet the tightening requirements, thereby reducing the use effect.
