Abstract

958,832. Valves. SAUNDERS VALVE CO. Ltd. July 22, 1960 [July 22, 1959], No. 25175/59. Heading F2V. A plug cock 1 comprises one or two journals and a spring pressed sealing ring 17 located at the plug end of the or each journal to check leakage from the surface of the plug over the journal surface and sealing means 30 preventing access of the atmosphere to the journal surface. As shown in Fig. 1 applied to a rotary spherical plug-cock for controlling liquid oxygen, the sealing ring 17 which may be of polytetrafluoroethylene, is located between a flange 16 formed on a spindle 7 and a block 27, the sealing ring being loaded by a spring 11. The spindle 7 is keyed to a stub shaft 6 on the plug 1 and is connected by a sleeve 25 to a drive shaft 24 operated, via a crank-and-lever arrangement 22, 23, by an hydraulic or pneumatic motor 21 or an electromagnetic device; in an alternative arrangement the spindle 7 is coupled to an operating shaft 34, Fig. 3, secured to a segmental gear 35 which is driven, via a rack 36, by a fluid-pressure actuated double-acting piston 37. The block 27, sleeve 25 and a further spacer block 26 may be made of a material having a low heat conductivity in order to minimize the possibility of liquid oxygen freezing on the valve journal.
