摘要： A choke may include an inlet for receiving a flow stream. The choke may also include a valve assembly configured to receive the flow stream from the inlet and control the flow stream. The valve assembly may include a cage element, an external sleeve adapted for selectively and controllably articulating over the cage element to control the flow stream through the valve, and an impact screen surrounding both the cage element and the external sleeve and adapted to protect the cage element and the external sleeve from impacts from large objects in the flow stream. The choke may also include an outlet for delivering the flow stream from the valve assembly.

摘要： A device (1) for controlling the flow of fluid through a conduit from an upstream side (3) to a downstream side (5). The device includes a housing (4) with a wall (6) having valve apertures (8) through which the flow of fluid is selectively controlled. A valve member (10) is mounted on one side of the wall of the housing and is arranged to move reciprocally to selectively open and close the valve apertures. A removable insert (12) is mounted on the opposite side of the wall of the housing from the valve member. The removable insert is arranged to cover some of the valve apertures.

摘要： Check valve units having one or more sound attenuating members are disclosed. A check valve unit includes a housing defining an inlet port, an outlet port, and a chamber in fluid communication therewith thereby defining a flow path from the inlet port through the chamber to the outlet port. The chamber includes first and second valve seats and has a sealing member disposed therein that is moveable from a position seated on the first valve seat to a position seated on the second valve seat. A sound attenuating member is disposed in the flow path downstream of the chamber, within the chamber, or both. In another embodiment, the check valve unit includes a Venturi portion in fluid communication with the chamber. The Venturi portion has a fluid junction with the flow path downstream of the chamber or forms the discharge section of the Venturi portion thereby defining the outlet port.

摘要： A variable orifice device for passing fluent material under pressure includes a piece of resilient material bent out of its normal shape so that one surface is in tensile stressed condition and the other surface is in compressive stressed condition. A slit extends between the two surfaces. Because of the difference in the stressed conditions of the two surfaces, one end of the slit is open and the other end, at the compressively stressed surface, is in forced closed condition. The piece of resilient material is mounted in its bent, stressed condition in a frame which holds the material in the bent condition. The piece of resilient material may be cut from silicone rubber tubing such as is used for peristaltic pumps. The frame may be two annular members, one of which is a push fit in the other, with the other having an annular shoulder against which a disc of the resilient material is trapped and sealed by the one annular member.

摘要： A control valve of the type wherein a valve member in the form of a piston moves axially within a piston guide cylinder located in a valve chamber. The valve chamber includes an inlet chamber, an outlet chamber, a valve seat area, and a main flow path and a plurality of by-pass ducts running through an inlet collar and terminating at the valve seat area. A by-pass admission duct which includes an entrance section located in a convexly curved portion of the inlet collar feeds the fluid controlled by the valve to the by-pass ducts and this duct which begins at a rotationally symmetrical throat section of the main flow path is generated by the respective boundary lines of the inlet collar and piston guide cylinder, the shortest connecting line between those boundary lines and an extension of the line which generates the valve seat area.
