Detailed Description

The following detailed description of the present application is given for the purpose of enabling those skilled in the art to better understand the technical solutions of the present application, and the description in this section is only exemplary and explanatory, and should not be taken as limiting the scope of the present application in any way.

Referring to fig. 1 and 2, the present embodiment provides a flange assembly with high sealing reliability, including a first flange 100 and a second flange 200; the first flange 100 is provided with a butt joint groove 110 along the circumferential direction, and the second flange 200 is provided with a ring-shaped butt joint 210 corresponding to the butt joint groove 110.

In a preferred embodiment, two sealing grooves 120 are arranged in parallel at the bottom of the docking groove 110, and a sealing ring 121 is arranged in each sealing groove 120; the butt joint 210 is provided with a sealing joint 220 corresponding to the two sealing rings 121, and sealing can be achieved by inserting the sealing joint 220 into the sealing groove 120 and pressing the sealing rings 121 into the sealing groove 120.

In a preferred embodiment, the deep portions of the two seal grooves 120 are different, the lengths of the two seal heads 220 are the same, when the seal grooves 120 with the shallower depth are installed to cooperate with the seal heads 220 to form a seal, the other group is in an idle state, when the seal ring 121 is worn and failed, the installation stroke of the seal heads 220 is increased, and the other group forms a seal.
