Sliding gate valve assembly for use with a vessel containing molten metal

摘要

A sliding gate valve for a vessel containing molten metal is provided which includes a housing and a lid pivotally mounted thereon. A sliding plate is sandwiched between two fixed plates and the three are received within the housing. Clamping elements are provided and are used in conjunction with the lid to secure the plates. A lock is provided to prevent movement of the lid in a direction parallel to movement of the sliding plate while allowing movement of the lid in a direction perpendicular to movement of the sliding plate. The lock is designed to assume a locked position whenever the sliding gate valve is mounted onto the vessel.
