Description

Technical Field

[0001] The utility model relates to the technical field of oil pipelines, in particular to a sealing joint for oil pipelines. Background Art

[0002] The sealing joint of the oil pipeline is the main facility for oil unloading and transfer. Generally, a single oil pipeline sealing joint is composed of multiple single pipes of the same specifications. Since the oil transportation process needs to withstand a large conveying pressure, the connection part between adjacent single pipes has high requirements. Commonly used single pipes are usually directly connected by flange connection. At present, the traditional sealing joint is connected by flange connection. At this time, multiple bolts need to be installed at the same time, and the installation action is cumbersome. On the other hand, when connected by flange, each position needs to be balanced to ensure that there will be no oil leakage during long-term use.

[0003] For example, a sealing joint for an oil pipeline with publication number CN219159773U is provided with a first convex pipe, a stopper block, a stopper groove and other structures, so that the oil pipeline and the sealing joint can be connected by plugging, and then the convex pipe is locked by a positioning bolt, so that the oil pipeline and the sealing joint are tightly connected. However, there is a gap between the stopper block and the stopper groove, or between the positioning bolt and the stopper block, and oil is likely to leak from the gap. Therefore, an oil pipeline sealing joint is proposed to make an improvement. Utility Model Content
