Abstract

517,722. Rotary disc valves. JACKSON & BROS., Ltd., HAMMOND, R., and FISH, J. R. June 1, 1938, No. 16329. [Class 135] An isolating valve, e.g., for insertion between a bleaching kier connected at 5 and a pump connected at 6, comprises a rotating valve member 8 in one position of which a passage 12 therein connects the passages 5 and 6 while in other positions the under-surface thereof seals the passage 6, stops such as fixed pins engaging the ends of grooves in the member 8 being provided to prevent the passage 12 from being turned into more than one position of registration with the passages 5 and 6. An aperture through the member 8 vents the passage 5 to atmosphere when the passage 6 is scaled. The passage 12 in the form shown splits into two around the spindle tube 13, a hand wheel 24 screwed on to the spindle 7 and locked by a wing nut 26 (complete removal of which is prevented by a collar 27) serves to clamp the valve in its various positions, and rubber sealing rings 14, having inwardly projecting lips 15 pressed on to the member 8 by the liquid pressure, surround the ends of the passages 5 and 6. A deflecting skirt 28 and a drain trough 29 discharge any leakage into a waste pipe and a marked plate 31 indicates the position of the valve member 8 which is rotated by a handle projecting laterally therefrom.
