US 11,994,177 B2 · Universal joint connection for the manual positioning of an angularly offset valve shaft drive

Abstract

A manual positioning assembly for connection to a shaft of a valve configured to manually manipulate a disc of the valve between an open and closed position. The manual valve positioning assembly includes a housing having a first and a second end. The first end includes a flange configured for fastening the housing to the valve. The second end includes a conical feature. An alignment bushing within the second end of the housing and a double universal joint. The double universal joint includes a first end and a second end. The first end of the double universal joint is configured to be mechanically fastened to the shaft of the valve. The second end is positioned within the alignment bushing and includes a socket configured to receive a tool that manually turns the double universal joint, the shaft, and the disc to position the disc in the open or closed position.
