Abstract

1355934 Valves BRUNSWICK CORP 3 Feb 1972 5144/72 Heading F2V In a ball valve having a housing provided with aligned inlet and outlet ports 14, 16, Fig. 1, the ball is retained in a generally cylindrical bore 20 by a plug 30. The ball is manually rotatable by a handle, not shown, to control fluid flow, and is mounted in two cups 24, 26. The plug 30 may be tightened to compensate for wear at the ball and cups, and may also be used to lock the ball in an adjusted position. Moreover, removal of the plug facilitates replacement of the ball and cups and machining of seat 38. The bore is inclined by 45 degrees to the axis of the ports 14, 16 but may instead be inclined at a lower or higher value, e.g. 90 degrees. In an alternative embodiment, Fig. 4 (not shown), the bore (120) is inclined at 135 degrees so that the orifice at the bottom of the bore is upstream of the orifice in the side wall of the bore. The ball and cups may be of rubber, nylon, polyethylene, polypropylene, brass, bronze, monel metal, cast iron, or cast or forged steel.
