ABSTRACT:
A connection for connecting an end hub (22) of a valve (10) to the flange (32) of an associated conduit (26). A bolting ring (36) has a threaded end portion (64) adjacent the valve (10), and a cylindrical smooth end portion (68) remote from the valve (10) extending radially inwardly from the threaded end portion (64). A shoulder (70) between the smooth portion (68) of the ring (36) and the threaded portion (64) acts as a stop to accurately position the bolting ring (36) onto the hub (22). Upon connection of the assembled valve structure to adjacent conduits (26), tensioning of the threaded studs (42) results in torque loads exerted by the smooth surface (68) on the locking ring (36) against the smooth surface (60) on the hub (22) for transmitting loads to the hub (22) as shown particularly in FIG. 5. The method includes the positioning of the locking ring (36 ) onto the hub (22) with mating cylindrical threads (64, 46) first being engaged and then adjacent smooth portions (60, 68) being engaged in a slight interference fit for subsequent connection of the valve (10) to conduits (26) by tensioning of the connecting studs (42).
