Abstract

127,939. Gibson, J. H., Cockburns, Ltd., Cockburn, D., and MacNicoll, D. May 21, 1918. Ball and float valves. - An airescape valve H for use in pressure liquidcirculating systems, such as the circulating-water systems of steam condensers, is controlled by a float D; a separate buoy. ant valve C is open when the casing contains water but closes the opening a<2>, and thus prevents access of air to the circulating-system, when the casing empties owing to failure of the pressure. The valve C may consist of a hollow rubber ball. The valve H is carried by the float D, which is heavy enough to ensure disengagement from the seating f<1> upon a fall in the water level. As shown in Fig. 7<A>, the main valve H' may be formed with a central port h<4> controlled by an auxiliary valve h<3>. The auxiliary valve h<5> is constituted by a boss formed on a spindle h<3> loosely attached to and moving with the float D. The main valve H' is capable of a longitudinal movement on the spindle h<3> that is limited by the boss h<5> and by a nut h', and is formed with radial guides h<7>. The float D is guided by ribs a<3>, and its downward movement is gradually arrested by a cup E, from which water is expelled by the weight of the float.
