Appl. No.:

12/332682

Inventors:

Nicholas Langmesser - Reno NV, US
Johnny Ellis - Reno NV, US
Kristopher M. Weide - Gladstone MI, US

Assignee:

Tyco Valves & Controls, LP - Houston TX

International Classification:

F16K 3/02

US Classification:

251328, 251358, 277574

Abstract:

A valve assembly preferably including a housing having a recess and a flange face and a valve sleeve disposed within the recess. The sleeve preferably includes an annulus having an outer surface and an inner surface that defines a passageway about a central axis, the outer and inner surfaces being radially spaced from one another to define a wall. The wall has a first end portion and a second end portion axially spaced from the first end portion, and homogenous material properties from the first end portion to the second end portion. Preferably, the first end portion defines a lip for supporting the annulus in the recess and further defines a first chamber that encases at least a portion of a first support member. The second end portion preferably defines a flange portion along the outer surface for engaging the flange and further defines a second chamber that encases at least a portion of a second support member.

US Classification:

137242, 251302

Abstract:

A rotary gate valve includes first and second opposing housing members having coaxial pathways and defining a gate channel when joined together. A gate is positioned within the gate channel when the valve is in a closed position to prevent media from flowing through the pathways and rotationally displaced from the channel when the valve is in an open position to allow media to flow through the pathways. First and second annular primary sealing sleeves are disposed within the first and second housing members and are adapted to sealingly engage each other when the valve is in the open position, and with the gate valve when the valve is in the closed position. A secondary sealing member is disposed around an upper portion of the gate and secured between the housing members above the first and second annular primary sealing sleeves to prevent process media from entering the housing members.

Abstract:

A rotary knife gate valve includes a gate which rotates above a process flow axis within a pipeline. The valve includes a valve body defining a flow path having in inlet and an outlet and a knife gate channel. A shaft that has a longitudinal axis is positioned within an upper portion of the valve body. The gate has a first end connected to the shaft and positioned within the knife gate channel when the valve is in a closed position and rotationally displaced from the channel when the shaft rotates perpendicular to the shaft axis to open the valve.
