A hatch and valve arrangement for a charging installation for a shaft furnace, such as a blast furnace, said arrangement comprising a housing (), inside which is located at least one hatch () and/or a valve (), caused to pivot by an actuator () located outside the housing and connected to the hatch or valve by a linking shaft guided in a bearing that is fixed with respect to the housing. The bearing () and the actuator () are mounted on a detachable door () that seals an opening () made in the wall of the housing () and whose dimensions are determined such that the hatch or the valve can be withdrawn transversely to the axis of the housing through said opening.

Door and valve assembly for a charging installation of a shaft furnace

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.
