Abstract

The invention relates to a flange and belongs to the technical field of design of flange equipment. The flange comprises a first flange plate and a second flange plate; both the first flange and the second flange are provided with corresponding mounting holes; and bolts pass through the mounting holes in the first flange plate and the mounting holes in the second flange plate to be screwed down and connected with nuts. The flange is characterized in that the peripheries of the mounting holes at both sides of the first flange plate are provided with convex sealing gaskets; the periphery of each mounting hole at one side of the second flange plate, which is in contact with the first flange plate, is provided with a circle of groove matched with the convex sealing gaskets; the periphery of each mounting hole at the other side of the second flange plate is provided with a circle of convex sealing gasket; and 2 to 10 mounting holes are respectively formed in the first flange plate and the second flange plate. The flange has a reasonable and simple structure and is easy to produce and manufacture; and in the specific using process of the flange, water is often effectively prevented from being leaked into the mounting holes; and the condition that the bolts are oxidized and rusted and even cannot be taken out of the mounting holes is prevented.

Description

technical field [0001] The invention relates to a flange and belongs to the technical field of flange equipment design. Background technique [0002] Flanges are also called flanges or flanges. Flanges are parts that connect pipes and pipes and valves to each other, and are connected to the pipe end. Flanges are generally used in pairs. A pair of flanges are provided with mounting holes corresponding to each other, and the pipes are well connected through the mounting holes through bolts and other connecting parts. The existing flange mounting holes are poorly sealed, and the bolts pass through the mounting holes. During use, water often leaks into the mounting holes, causing the bolts to oxidize and rust. maintain. Contents of the invention [0003] The object of the present invention is to solve the above problems and provide a flange with simple and reasonable structure, easy manufacture and high sealing performance of the mounting hole. [0004] The object of the pr...
