摘要
A sealing valve arrangement for a shaft furnace charging installation includes a shutter-actuating device for moving a shutter between a closed position in sealing contact with a valve seat and an open position remote from the valve seat. The shutter-actuating device is of the dual-motion type and includes a primary tilting arm on a first tilting shaft defining the first axis and is equipped with bearings supporting the primary tilting arm. A secondary tilting arm carries the shutter is connected to a second tilting shaft that defines a second substantially parallel axis and has bearings that support the secondary tilting arm on the primary tilting arm. The shutter-actuating device has a mechanism configured to tilt the secondary tilting arm when the primary tilting arm is tilted. The first tilting shaft is configured as hollow sleeve shaft and the shutter-actuating device includes a reference rod extending through the first tilting shaft.
