Abstract

1515363 Valves PEGLER HATTERSLEY Ltd 20 Feb 1976 [28 Feb 1975] 8617/75 Heading F2V A ball closure valve has a seal for the ball 13 in the form of a ring having first and second parts 27, 28, the first part arranged to seat against the adjacent walls 20a, 20b of a housing formation (e.g. rebate 20) and the second part being flexible, integral with the first part, loaded against the ball by resilient reinforcement 29 and having primary and secondary sealing surfaces 31, 30. Auxiliary seals 21 are located at the formations and are engageable by the ball if seals 27, 28 are destroyed by excessive heat. As shown in Fig. 1 the ball 13 is free to locate between the ring seats and is rotatable by a stem 15 through a non-circular ball 16 in a non-circular socket 17 whereas in Fig. 2 (not shown) a trunnion 23 locates the ball 13. The seal Fig. 3 has a flexible leg portion 28 with a part circular portion 27c over which a spring 29 extends. In Fig. 2A (not shown) fusible stem and trunnion housings (13a) are provided so that if the seals are destroyed by fire the ball may be moved by pressure to engage the auxiliary seals.
