Problems solved by technology

[0002] Flanges are widely used in the connection of industrial pipelines. Ordinary flanges can only play the role of connection, not sealing. During the use of flange connection, the liquid medium flowing in the pipeline often flows from the flange. The connection of the flange overflows, causing leakage and affecting normal work; and when the traditional flange is connected, it is difficult to accurately control the relative position, which will also cause the deviation of the flange connection, and the tight connection will cause leakage. Lan to improve

Abstract

The invention discloses a flange assembly comprising an upper flange body, a lower flange body, a first boss, a second boss, a first sealing gasket, a second sealing gasket, a waterproof gasket, a third sealing gasket, a first sealing ring, a flange connecting plate and connecting nuts. An annular groove at the lower end of the upper flange body is connected to the second boss at the upper end of the lower flange body through threads, and the second boss of the lower flange body is internally provided with the third sealing gasket and the first sealing ring. According to the flange assembly disclosed by the invention, through threaded connection, the accuracy of the connection position between the upper flange body and the lower flange body is ensured, and the relative position of flanges is prevented from offsetting during installation, so that the installation efficiency and accuracy of the flanges are improved; the connection of the flanges is more secure through the connecting nuts and the flange connecting plate; through the structural design that the third sealing gasket and the first sealing ring are higher than the connection, the airtightness of the connection between the upper flange body and the lower flange body is ensured; and faults, such as errors and leakage, are avoided, and the production safety is ensured.

Description

【Technical field】 [0001] The invention relates to the technical field of flanges, in particular to the technical field of a flange assembly. 【Background technique】 [0002] Flanges are widely used in the connection of industrial pipelines. Ordinary flanges can only play the role of connection, not sealing. During the use of flange connection, the liquid medium flowing in the pipeline often flows from the flange. The connection of the flange overflows, causing leakage and affecting normal work; and when the traditional flange is connected, it is difficult to accurately control the relative position, which will also lead to deviation when the flange is connected, and it cannot be tightly connected to cause leakage. Lan to improve. 【Content of invention】 [0003] The purpose of the present invention is to solve the problems in the prior art, and propose a flange plate assembly, which is easy to install, firm in structure, accurate in flange connection position, good in seali...
