Abstract
The specification discloses an isolation gate valve (10) for controlling flow of a particulate type material of a dry or semi dry nature including ore and coal, the gate valve (10) having a support frame (11), at least one slidable blade member (20, 21) movably mounted relative to said support frame (11) to selectably open or close a material flow opening (12) defined by said support frame (11), one or more actuators (22, 23) provided to drive the slidable blade member or members (20, 21) between open or closed positions, the or each said slidable blade member (20, 21) having a forward leading edge region (27, 28) adapted, in use, to transversely extend across the material flow opening (12).
Claims20
An isolation gate valve having a support frame structure defining a material flow opening, at least one blade member movably mounted relative to the material flow opening in said support frame structure, said movably mounted blade member being supported on a lower face by multiple spaced rolling elements, at least one of said rolling elements being formed as a roller cartridge member having an outer plate structure releasably connected to said support frame structure and a roller sleeve rotatably mounted to said outer plate structure and extending inwardly through an aperture in a wall region of the support frame structure, the aperture being sized sufficiently to allow the roller cartridge member including the roller sleeve to be bodily removed from the support frame structure.
A slide blade member for use in an isolation gate valve having a support frame structure defining a material flow opening, the slide blade member, in use, being adapted to at least partially close or open said material flow opening, said slide blade member including at least one cartridge assembly with at least one rolling element having a rolling surface extending partially laterally from a side edge zone of said slide blade member, the or each said rolling element being mounted on a mounting shaft carried by a said cartridge assembly, the cartridge assembly is bodily connectable to or removable from upper or lower faces of said slide blade member or said side edge zone of said slide blade member.
