[0002] Flange, also known as flange or flange, is a part that connects shafts, pipes, valve accessories, etc. It is widely used in pipeline construction and equipment connection. The flange connection is composed of flange, gasket and bolts to form a detachable sealing structure. There are holes on the flange, and the bolts connect the two flanges tightly. The flanges are sealed with gaskets.

[0003] However, there are still some problems when connecting existing flanges:

[0004] An existing flange joint such as CN202852254U includes two joint bodies and left and right flanges. A through hole is provided in the center of the two joint bodies. When the two joint bodies are butt-jointed, the left and right ends are pipe connection ports. A boss is provided on the outer wall of the joint body. The two joint bodies are fixedly connected together through the left and right flanges. The bosses of the two joint bodies are clamped in the clamping grooves of the left and right flanges, and the left and right flanges are connected together by bolts and nuts.

[0005] When assembling and connecting existing flanges, the connection method mostly relies on bolts, nuts and other fasteners for fixing. However, during the installation process, a lot of time is needed to tighten the bolts one by one, which is not only complicated to operate, but also significantly increases the time consumption, affects the efficiency of installation and maintenance, and reduces the demand for use.
