Abstract
A sealing valve arrangement for a shaft furnace charging installation, said arrangement comprising: a shutter arranged for cooperating with a valve seat; an integrated dual-motion shutter-actuating device for moving said shutter between a sealed closed position in sealing contact with the valve seat and an open position remote from the valve seat, said integrated dual-motion shutter-actuating device comprising: a primary motion assembly for moving said shutter from said sealed closed position to an undamped position wherein the shutter is released from the valve seat; a secondary motion assembly for tilting said shutter from said undamped position to said open position remote from the valve seat, said secondary motion assembly comprising a tilting arm carrying said shutter and connected to a tilting shaft that defines an axis of rotation and a tilting shaft actuator configured to impart an angular rotation about said axis to said tilting arm; wherein said integrated dual-motion shutter-actuating device further comprises a stationary outer cylindrical sleeve, wherein said primary motion assembly comprises an inner eccentric sleeve shaft rotationally mounted within said outer cylindrical sleeve and a primary motion actuator configured to impart angular rotation to said inner eccentric sleeve shaft, the primary motion being a function of the eccentricity and angular rotation of the inner eccentric sleeve shaft; and wherein said tilting shaft of said secondary motion assembly is rotationally mounted within said inner eccentric sleeve shaft of said primary motion assembly, the secondary motion being a function of the angular rotation of the tilting shaft.
