Abstract
A coupling is used to couple a linear actuator with a slider valve unit in a sliding gate valve for a molten metal vessel. The slider valve unit is slidably mounted in a slider housing for movement in a longitudinal direction, and has a push rod for this purpose. A linear actuator mounting is provided on the slider housing, and the linear actuator is mounted in the linear actuator mounting. The linear actuator has a drive rod movable in a longitudinal direction when the linear actuator is mounted in the linear actuator mounting. The coupling has a structure such that when the linear actuator is mounted in the linear actuator mounting, and the drive rod is moved toward the slider valve unit, the coupling automatically couples the drive rod with the push rod. Furthermore, when the linear actuator is removed from the linear actuator mounting, the coupling automatically uncouples the drive rod from the push rod.
