Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of pipeline joints, in particular to a flanged joint with an isolation sealing structure. Background Art
[0002] The flange joint is a special pipe joint with a unique structure and function. It is usually used to connect pipes, especially when it needs to withstand high pressure, high temperature or complex installation environment. The structural characteristics of the flange joint are mainly reflected in its flange part, which forms a tight fit with the connecting part of the pipe or other joints, thereby achieving a good sealing effect; there are many types of flange joints on the market, including two major categories: straight type and curved type.
[0003] When in use, common flanged joints mainly rely on the flatness of the flanged surface of the flanged part to achieve the sealing effect, or rely on the elasticity of the flanged part. After the fixation is completed, the flanged part is used to press against the external pipe to complete the sealing operation. However, this type of flanged joint lacks a corresponding isolation sealing structure on the side, and cannot perform efficient isolation sealing operations. It is difficult to achieve a good isolation sealing effect by only relying on the flanged part to press against the external pipe directly. In view of this, we propose a flanged joint with an isolation sealing structure. Utility Model Content
