[0002] Flange, also known as flange flange or flange. Flange is a part that connects shafts to each other and is used to connect pipe ends. It is also used as a flange on the inlet and outlet of equipment to connect two devices, such as reducer flange. Flange connection or flange joint refers to a detachable connection in which flange, gasket and bolts are connected to each other as a combined sealing structure. In addition, the use of double wedge angle gaskets as sealing rings in high-pressure heat exchanger flanges can better seal. When the existing double wedge angle gasket flange structure is used, the two flanges are directly fitted and connected, so that the flange joint with double wedge angle gaskets is plugged into the interface of another flange, and there is no limiting guide structure, which makes it difficult to accurately align the screw holes on the flange when using bolts to tighten and fix. This leads to inconvenience in installation work. For this reason, we propose a flange structure with double wedge angle gaskets. Utility Model Content
