Abstract
1434768 Valves WESTINGHOUSE BRAKE & SIGNAL CO Ltd 6 June 1974 [7 June 1973] 27219/73 Heading F2V A valve, e.g. in a line for conveying pulverized coal by steam, comprises a rectangular aperture 20 in a frame 10 defined by U-section members 11 to 14, and two part cylindrical closure members 31 secured by webs 36 to respective rotatable shafts 32, 33 for movement between a fully open and a fully closed position, shown, in which adjacent straight edges of the members abut at 34. Each member 31 is sealed within aperture 20 by a trapezoidal seal 24 retained in a tapering groove between two parts of a plate 23 extending parallel to the shafts 32, 33, and by trapezoidal seals (25, Fig. 2, not shown) retained in grooves between plates 22 and the frame side members 12, 14. Shafts 32, 33 carry intermeshing gears (41, 42, Figs. 2, 3, not shown) one of which (41) is connected by a link (46) and yoke (45) to a double acting pneumatic actuator (43). The gearing may be provided with a detent so that an intermediate valve opening can be maintained. Indicators may show the degree of opening. The valve may alternatively be manually actuated by a lever on shaft 32. Two valves may be connected together in series and operated by a sequence system.
