Abstract: 1444667 Cupping; making valves ROCKWELL INTERNATIONAL CORP 3 Oct 1974 [19 Nov 1973] 42903/74 Headings B3Q and B3A [Also in Division F2] A dome-shaped diaphragm for a valve where it separates the fluid control part of the body from the part containing the actuating mechanism is made from a number of thin metal discs. The discs are initially clamped between two annular members in a pressure vessel and hydraulic pressure is applied to one side of the stacked discs until the desired degree of curvature is obtained. This may be sensed by a limit switch or other control set at a predetermined point. This method provides a slight difference in curvature of the individual discs so that opposing faces are matched. After removal from the pressure vessel the discs can be heattreated. Thereafter they are fusion welded to the body of the valve. A suggested material is "Inconel" (Registered Trade Mark).
