Description

Technical Field

[0001] The utility model belongs to the technical field of high-pressure union sealing rings, in particular to a high-pressure union sealing ring adopting a spring frame. Background Art

[0002] High-pressure union rubber rings are essential for high-pressure union connections in oil extraction and other industries. The service life of this rubber ring is directly related to the duration of high-pressure manifold operation. It is mainly used in the oil industry and is a seal installed in the high-pressure manifold union.

[0003] Many current unions use sealing rings reinforced by metal frames. Such metal frame union seals usually need to be installed using an installation hammer. During the installation process, fatigue cracks are easily generated inside the metal frame, and it may even break directly. At the same time, it is very difficult to remove it for replacement, which greatly affects its sealing performance and service life. Therefore, we propose a high-pressure union sealing ring with a spring frame. Utility Model Content
