Abstract

447,244. Valves. MARLEY, W., Hawkshead Works, Workington, Cumberland. Nov. 7, 1935, No. 30790. [Class 135] The invention relates to hot blast valves for blast furnaces of the slide valve type. In order to prevent leakage of the hot blast cutting or scoring the closure surfaces when the valve is in the closed position a stream of cold blast is admitted to the valve casing to surround the valve member with a blanket of relatively cold air which serves as the source of supply for any gaseous leakage. The cold blast is admitted to the hood 6 when the main valve is closed through a spring - loaded lift valve 7 actuated by a cam 8 interconnected with the linkage 10 operating the main valve.
