摘要： An orifice plate carrier (70, 305) for positioning an orifice plate within an orifice fitting (12) to measure fluid flow rate through a conduit is disclosed. In some embodiments, the plate carrier (70, 305) has an opening (225) therethrough and an inner surface (207) surrounding the opening (225). A lip (230) extends radially from the inner surface (207) to support an orifice plate assembly (72) with an orifice plate disposed therein. At least one flow port (220, 315) extends through the body (205). Each flow port (220, 315) is configured to allow fluid therethrough and to reduce a pressure differential between fluid up and downstream of the orifice plate during installation and extraction. At least two notches (235), each notch (235) extending radially from the inner surface (207), engage the orifice plate and maintain the concentric position of the orifice plate within the fitting (12).

摘要： A dual chamber orifice fitting, including a body with a lower chamber in fluid communication with a pipeline and a top with an upper chamber in fluid communication with the lower chamber. A valve assembly closes to hydraulically isolate the upper chamber from the lower chamber and opens to allow an orifice plate carrier to move between the chambers. When the orifice plate carrier is in the lower chamber is can be aligned with the flowbore of the pipeline. The orifice plate carrier can be removed from the fitting through the upper chamber. In some embodiments, at least one of either the upper or lower chambers has a curved cross-section including inner and outer radii, a Cassini oval or a dog-bone shape. The body and top may also have a double curved outer surface to accommodate the curved cross-section of the interior chambers.

摘要： Apparatus and methods for operating a dual chamber orifice fitting. The dual chamber orifice fitting comprises a body having a lower chamber and a top having an upper chamber. An aperture connects the upper chamber to the lower chamber. A closure member is pivotally mounted to the fitting and pivots about a first axis between a first position and a second position. A pivot arm is rotatably mounted to the body and engages the closure member so that rotation of the pivot arm about a second axis pivots said closure member about the first axis between the first and second positions.

摘要： Methods and apparatus for a bi-directional dual chamber orifice fitting comprising a body with a chamber in fluid communication with a flow bore. The fitting also comprises an orifice supported by an orifice plate carrier that is selectably disposable in the bore. In the preferred embodiments, the lower chamber includes two passageways connecting the chamber to the flow bore. One passageway is located on either side of the orifice plate. Each passageway may also be equipped with a check valve to permit flow in only one direction through the passageway. In operation, the passageway on the upstream side of the orifice would allow fluid to flow into the lower chamber while the passageway on the downstream side would prevent flow back into the flow bore.

摘要： Apparatus and methods for operating a valve assembly for a dual chamber orifice fitting. The dual chamber orifice fitting comprises a body attached to a top. A passageway connects between the body and the top and allows an orifice plate carrier to move between the body and the top. A valve assembly selectably closes the passageway. Embodiments of the valve assembly comprise a seat, a plug, and a stem. The valve assembly has a closed position, wherein a curved outer surface of the plug sealingly engages a curved sealing surface of the seat and prohibits fluid communication through the passageway. The valve assembly has an open position, wherein a plug aperture is aligned with a seat aperture to allow the orifice plate carrier to move through the passageway.
