Abstract

120,845. Cockburns, Ltd., Cockburn, D., and MacNicoll, D. March 28, 1918. Addition to 110,096. Closure members, double-beat; rotating and grinding valves on seats.-A double-beat valve, of the kind in which one beat is attached to the spindle by means of a diaphragm 1 imprisoned in a cell formed between the valve member 2 and a covering-member 3, has the valve member provided with a port 6 to admit outlet pressure beneath the diaphragm, and has a nut 8 on the spindle adapted to engage a sleeve 4 on the covering-member to clamp the diaphragm between a backing-plate 9 and the member 3 to facilitate the simultaneous grinding of both valve members.
