Abstract

622,149. Rotary plug cocks. WESTING- HOUSE BRAKE & SIGNAL CO., Ltd. (White, J.). Jan. 6, 1947, No. 364. [Class 135] A plug cock has a casing provided with annular flexible seating members against the inner peripheries of which the plug is adapted to.seat, the ends of the plug being in communication with the atmosphere so that a pressure difference acts on the seating members-tending to hold them in close contact with the plug. As shown, the casing comprises a central portion 1 having annular shoulders 8 against which bear clamping washers 9 backing up the annular seating members 10 which are made, for example, of rubber with fabric inserts and are clamped in position by end fittings 6, 7, having flanges or spigots for attachment to pipes. The plug 17, which is spherical, has a spindle portion 20 passing through a bush 23 whose inner end engages a packing ring 25, and a spindle portion 19 having ports 28 which, in the fully open or fully closed position of the plug, place passages 29, and therefore, the ends of the plug, in communication with the atmosphere through an opening 22. As the plug is rotated pressure fluid can pass between the ends of the port 27 and the seating members into the central space between the seating members to equalize the pressures on either side thereof and facilitate movement of the plug, but to ensure that this passage of fluid does not occur before the passages 29 are closed the port 27 is shaped with two inwardlyprojecting tongues 30.
