Abstract
A swivel joint and connection for abutting high pressure hydraulic manifolds, the joint comprising two flanged non-rotating swivel bodies with one of the non-rotating swivel bodies having a rotating swivel body journaled therein. A flanged tubular sleeve is secured between the adjacent end faces of the two non-rotating swivel bodies with the opposite ends of the tubular sleeves received respectively in counterbores formed in one non-rotating swivel body and in the rotating swivel body, respectively. A static annular seal is disposed between the first end of the tubular sleeve and the counterbore in the non-rotating swivel body. A resilient dynamic annular seal is disposed between an annular shoulder on the opposite end of the tubular sleeve and a first counterbore in the rotating swivel body. A cylindrical outer surface extends from the annular shoulder of the tubular sleeve within a second counterbore in the rotating swivel body and a sliding annular piston is disposed between the inner surface of the second counterbore and the cylindrical surface of the tubular sleeve. A hydrogen sulfide-resistant liquid is disposed within the annular cavity between the inner wall of the second counterbore and the cylindrical surface of the tubular sleeve intermediate the dynamic annular seal and the annular piston. An annular filter is also positioned between the end face of the tubular sleeve and the second counterbore in the rotating swivel body intermediate the annular piston and the end face of the tubular sleeve.
