ACTUATOR MECHANISM FOR A ROTARY VALVE |
摘要 |
A tundish (11) has located alongside it an upright support member (20). A cross arm (22) is pivotally mounted on the member (20) with one end of the cross arm (22) overlying the tundish (11). A hydraulic or pneumatic ram (25) is mounted in the member (20) for applying a downward force on the overlying end of the cross arm (24) which mounts a drive means (27) connected to the stem (14) of a rotary valve (12) for controlling the exit of hot or corrosive liquid from the tundish (11). |
