Description

Technical Field

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

[0002] Flange, also known as flange flange or flange, is a part that connects shafts to each other. It is used to connect pipe ends. It is also used at the inlet and outlet of equipment. It is used to connect two devices, such as reducer flange, flange connection or flange joint. Pipe flange specifically refers to a detachable connection of a combined sealing structure consisting of flange, gasket and bolts connected to each other as a group. Pipe flange refers to the flange used for piping in pipeline devices. It is used on equipment to refer to the inlet and outlet flanges of the equipment. There are holes on the flange, and the bolts make the two flanges tightly connected. The flanges are sealed with gaskets, but the two When the flange gaskets are butt-jointed, due to the lack of a limiting structure on the outside of the gaskets, the two sets of flange gaskets will be deformed when subjected to the pressure of the closed butt joint after butt-jointing, causing the two sets of flange gaskets to offset and then appear gaps, making them incompletely waterproof. When the two sets of pipe outer flanges are butt-jointed, they are connected and fixed by multiple sets of bolts, and the degree of tightening of each set of bolts is determined by manpower, which makes the tightness of the connection and fixation between each set of bolts vary, which also causes gaps in the overall fixed connection of the flange.
