Abstract: A fluid flow control device, sometimes called a variable fluid restrictor control valve or severe service control valve. These valves employ a moveable plug and are used to control high pressure fluids e.g. superheated steam. The valve of the invention provides axial flow passageways for the fluid, which have right-angled turns. The passageways are either on the radially outer surface of the plug or within an annular sleeve through which the plug is moveable.

Abstract: A disk valve construction having relatively movable face to face disk upstream of a sleeve member at an outlet chamber of the valve. The sleeve member includes a truncated conical portion to produce a desired pressure drop, while, at the same time reducing the turbulence of the fluid flow during operation of the valve. The sleeve member is maintained in position by way of pressure of the fluid, thereby avoiding the necessity of epoxy to hold the sleeve member to the valve body. The sleeve can be provided with an end wall with a discharge opening of a predetermined size at the downstream end of the sleeve for producing a predetermined fluid pressure drop.

Abstract: To improve the turn-down ratio and reduce the erosiveness of the discharge flow in a multiple orifice valve having a movable upstream disk and an abutting stationary downstream disk, particularly when the disks are subjected to high fluid pressures, the disks are provided with cooperating fluid conducting openings having a modified circular sector shape. In the preferred embodiment, the modified circular sector shape of the fluid conducting openings includes a primary opening portion formed in the general shape of a circular sector and a secondary opening portion comprising a pair of substantially semicircular supplemental openings, one of the pair of openings being provided at a radially outermost location along a first one of two radially directed walls defining therebetween the central angle of the circular sector shaped primary opening portion, the other of the pair of supplemental openings being provided at a similar location along the second one of the two radially directed walls. The semicircular supplemental openings, when properly aligned to an optimum turn-down position, provide a significantly increased turn-down ratio and low-erosion discharge flow thorugh the downstream disk which is essentially always parallel with a central plane bisecting the fluid conducting openings of the downstream disk and passing through a common central axis of the disks.

Abstract: A testing apparatus is provided for comparative testing of disk passage resistance of various disks in a high energy loss disk stack to detect blocked, broken down or irregularities in the various disks or individual passages thereof. The testing apparatus includes a plug which is sealably movable within a central core of the disk stack to supply air to labyrinth passageways formed at predetermined stack heights by aligning an air outlet on the plug with the labyrinth passageways formed at that stack height. The plug is connected to a pressure gauge calibrated to indicate a normal range of labyrinth resistance. Readings below the normal range indicate broken down or low resistance labyrinths while readings above the normal range indicate high resistance or blocked labyrinths.

Abstract: A more compact high energy loss device is provided having a series of uniquely formed multiturn labyrinth assemblies which reduce the pressure of a fluid flowing therethrough. The inlet of the labyrinth assemblies is formed according to a substantially circular configuration to have a predetermined inlet area while the outlet is formed according to a substantially scalloped configuration to provide an outlet area greater than the inlet area. The scalloped configuration of the outlet yields an outlet area which is also greater than if the outlet were of circular configuration. The scalloped outlet configuration also makes the labyrinth assembly less susceptible to circumferential thermal stresses resulting from high temperature fluids passing through the device producing high temperature inlet conditions and low temperature outlet conditions.

Abstract: A flow control device includes a stack of annular discs positioned in a flow path. Each disc includes fluid passageways extending between inner and outer perimeters of the disc, with each passageway defining a flow axis extending out of the disc and radially offset from a central axis of the discs. A plug is moveable relative to the discs between closed and open positions. In the closed position, a cylindrical section of the plug is positioned to block fluid flow through the annular discs. In the open position, the annular discs and a tapered section of the plug collectively define an annular vortex chamber. The fluid passageways in the annular discs and the tapered section of the plug collectively impart a rotational flow when the plug is in the open position and as fluid exits the annular discs.

Abstract: A method of designing a three-dimensional flow control element includes creating a first computer aided design representative of a flow configuration having a first end and a second end. A second computer aided design of a host body is created. The design of the flow configuration is digitally inserted into the design of the host body such that the two designs define an overlapping region. The first computer aided design and the portion of the second computer aided design in the overlapping region is subtracted from a remainder of the second computer aided design to produce a third computer aided design of a flow control element having a fluid pathway extending therethrough. The fluid pathway is associated with the overlapping portions of the first and second computer aided designs.
