Description

Technical Field

[0001] The utility model relates to the field of sealing elements, in particular to an elastic sealing element structure. Background Art

[0002] An O-ring is often provided between the flanges of the pipeline to ensure the sealing performance between the flanges of the pipeline. For example, the Chinese patent with patent number CN201510144535.0 provides an internal L-shaped sealing ring for flange connection, which includes a socket part and a gasket part, and the radial cross section of the internal L-shaped sealing ring is "L" shaped. When the internal L-shaped sealing ring of the present invention is used, the socket part is inserted into the flange connection pipe to fix the gasket, so that it is not easy to deviate and misplace during the installation process, which can effectively speed up the construction process, save time and effort, and improve construction safety. For example, the flange sealing structure in the above-mentioned prior art needs to place the sealing ring between the two flanges during the installation process. The sealing ring will age after long-term use, resulting in a decrease in its sealing performance. When the seal needs to be replaced, the pipes and flanges at both ends need to be completely disassembled. Since the pipes are generally fixed on the equipment, the disassembly of the flanges is very cumbersome. Utility Model Content
