Abstract

711,636. Valves. KOPPERS GES., H. Dec. 31, 1951 [Jan. 9, 1951], No. 30484/51. Class 135 In a rotary spherical plug cock for controlling the flow of fine grained material, e.g. coal to a high pressure chamber to be gasified, a metallic spherically-faced seating ring 26 disposed on the side of the plug remote from the chamber is sealed against the plug 1 by hydraulic or pneumatic pressure supplied through a pipe 35. A T-shaped ring 10 having a facing of soft material e.g. rubber or soft metal, is sealed against the other side of the plug by hydraulic or pneumatic pressure supplied through a pipe 23. The seating ring 10 is connected to a pressure ring 11 so that when the hydraulic or pneumatic presing ring 10 is connected to a pressure ring 11 through a pipe 24, the ring 10 is urged away from the plug to permit easy rotation of the latter. The flat sides 2 of the plug are formed with recesses 7 engageable by ribs on couplings 6 integral with the operating spindle 4 and a shaft 5.
