Abstract
1390049 Valves BAKER OIL TOOLS Inc 14 Dec 1972 [22 March 1972] 57737/72 Heading F2V [Also in Division E1] A ball valve assembly V, Fig. 1, for use in offshore wells, comprises an elongated outer casing containing a fixed member 40, Figs. 8 and 9, supporting ported valve ball 46, and upper and lower sleeves 60, 53 sealingly cooperating with the ball. The ball has in opposite sides thereof recesses 45 engaged by fixed pins 44 extending from member 40. Upward or downward movement of the ball within the member 40 causes the ball to rotate, due to the co-operating pins 44 and recesses 45, and thereby closes or opens the flow passage through the valve. The co-operating surfaces of the pins and recesses are so arranged that initial downward movement of the ball from its closed position shown in Fig. 8, occurs without rotation of the ball so that the ball moves out of contact with resilient seal 103 before it rotates to its open position. Stop surfaces 91a, 91b on the ball co-operate with a surface on the member 40 to limit rotation of the ball. The ball is moved downwards by the sleeve 60 when piston means thereon are subjected to control pressure fluid supplied through pipe CF from a pressure source 11 mounted on floating platform P. Prior to moving the sleeve 60, the control pressure fluid causes a valve sleeve (67), Fig. 2a (not shown), to move along the sleeve 60 to an open position wherein ports in both sleeves are communicated to thereby allow well pressure below the ball to pass to the upper side of the ball and provide pressure balance. The valve sleeve (67) has longitudinally extending resilient latching fingers (74) with projections thereon which are forced out of engagement with a shoulder on sleeve 60 by camming action during opening movement of the valve sleeve. Upward closing movement of the ball occurs automatically after cessation of control pressure fluid flow, by the action of well pressure and by a helical spring (51), Figs. 2b, 2c (not shown).
