ARRANGEMENT FOR OPERATING A SHUT-OFF VALVE HAVING A TAPERED PLUG

摘要

Arrangement for actuating shut-off valve with tapered plug, has housing in which hollow actuating cylinder is coaxially supported for rotation and with an actuating shaft aligned with the coaxial axis firmly attached. Output cylinder is coaxially arranged in hollow actuating cylinder. The output cylinder is movable relative to hollow drive cylinder axially and radially. Spindle is attached on output cylinder opposite actuating shaft and aligned with coaxial axis; tapered plug being fastened on end of spindle facing away from output cylinder. At least one radially outwardly directed pin is arranged on outer peripheral surface of output cylinder. Outer surfaces of housing and hollow actuating cylinder have each at least one guideway extending over radial sector of outer surfaces, with which pin is operatively connected as a respective sliding block. At least the guideway arranged in outer surface of hollow actuating cylinder is formed as a through-opening through which pin passes.

1. An arrangement for actuating a shut-off valve with a tapered plug, the arrangement comprising
a housing (1) in which a coaxially and rotatably supported hollow actuating cylinder (4) is arranged, an actuating shaft (3) aligned with the coaxial axis (2) is fixedly attached on the cylinder (4), an output cylinder (5) also coaxially arranged in the hollow actuating cylinder (4) and which is axially and radially movable with respect to the hollow actuating cylinder (4), a spindle (6) fixedly mounted on the output cylinder (5) and oriented along the coaxial axis (2) opposite to the actuating shaft (3), a tapered plug (7) affixed on the end of the spindle (6) facing away from the output cylinder (5), wherein at least one radially outwardly oriented pin (8) is arranged on the outer peripheral surface of the output cylinder (5), the outer surfaces of the housing (1) and of the hollow actuating cylinder (4) each have at least one guideway (10 and 11) extending over a radial sector of the outer surfaces, with which the pin (8) is operatively connected in the manner of a respective sliding block, and wherein at least the guideway (10) arranged in the outer surface of the hollow actuating cylinder (4) in formed as a through-opening through which the pin (8) passes.
