Abstract

1,225,567. Valves. HILLS-McCANNA CO. 3 April, 1969, No. 17616/69. Heading F2V. A high-pressure ball valve comprises seat members 60, 62, each supported on the spherical face of the plug and the similarly shaped face 78 of a support 84, and formed U-shaped in radial cross-section with annular portions 68, 70 extending radially inwards to define a seat spreading space 72 into which fluid can enter to force the portions apart, the arrangement allowing the ball 124 to move transversely of flow passageways 18, 20, when a bonnet gland 124 is adjusted. Each seat is made from a flexible polymeric material and is supported by a metal outer ring 66. The valve ball 12 and supporting spindles 28, 30 are made in one piece, and the latter is sealed by packing members 40, 46 which can be adjusted by a nut 52. The bonnet sealing gland 124 is adjusted by a nut 138. In Figs. 4 and 5 (not shown), the annular portions of the seat members 64 are forced apart by springs (92), (98) respectively. In Fig. 6 (not shown), separate metal leg portions are located in a groove (104) of an outer ring (66c) and are moved apart by an annular wave spring (114). The seat in Fig. 7 (not shown) is formed from spring metal with flexible inserts (68c), (70c).
