Abstract
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.
Claims28
An assembly, comprising:
- a housing;
- a valve member, located within said housing, moveable in a direction of movement;
- a lid pivotally mounted to said housing;
- and
- a lock, mounted to said housing, having an unlocked position and a locked position in which said lid is prevented from moving parallel to said direction of movement but is permitted to move in a direction perpendicular to said direction of movement;
- wherein said lock is comprised of a pin and at least one cam formed thereon such that said lock is rotatable between said unlocked position in which an outer periphery of said at least one cam is spaced apart from said lid and said locked position in which said outer periphery of said at least one cam abuts said lid.

An assembly, comprising:
- a housing;
- a valve member, located within said housing, moveable in a direction of movement;
- a lid pivotally mounted to said housing;
- and
- a lock, mounted to said housing, having an unlocked position and a locked position in which said lid is prevented from moving parallel to said direction of movement but is permitted to move in a direction perpendicular to said direction of movement;
- wherein said lock is comprised of a pin and at least one cam co-linearly formed thereon;
- and
- wherein an outer periphery of said at least one cam is spirally shaped such that a radius, measured from said axis of said at least one cam to said outer periphery, increases as said lock moves from said unlocked position to said locked position.

An assembly, comprising:
- a housing;
- a valve member, located within said housing, moveable in a direction of movement;
- a lid pivotally mounted to said housing;
- and
- a lock, mounted to said housing, having an unlocked position and a locked position in which said lid is prevented from moving parallel to said direction of movement but is permitted to move in a direction perpendicular to said direction of movement;

An arrangement for a valve, comprising:
- a housing having a cavity shaped to receive a valve member such that said cavity allows the valve member, when the valve member is received by sad cavity, to move in a direction of movement;
- a lid pivotally mounted to said housing;
- and
- a lock, mounted to said housing, having an unlocked position and a locked position in which said lid is prevented from moving parallel to said direction of movement but is permitted to move in a direction perpendicular to said direction of movement;
- wherein said lock is comprised of a pin and at least one cam formed thereon such that said lock is rotatable between said unlocked position in which an outer periphery of said at least one cam is spaced apart from said lid and said locked position in which said outer periphery of said at least one cam abuts said lid.
