Abstract:

A fluid pressure reduction device comprises two or more stackable annular plates. Each disk having a perimeter and a hollow center aligned along a longitudinal axis when the annular plates are stacked one on top of the other. Each disk further comprising at least one inlet flow sector having an inlet flow stage for defining a first inlet area and a first outlet area, and at least one outlet flow sector having an outlet flow stage defining a second inlet area and a second outlet areas wherein the ratio of the second inlet area to the second outlet area is predetermined to define a backpressure at the outlet flow stage to provide a sub-sonic fluid flow at the perimeter.

International Classification:

F16K 1/00

US Classification:

251360000

Abstract:

Low distortion seat ring assemblies for use with fluid valves are disclosed. An example seat ring assembly includes a seat ring having an outer circumferential surface and a shoulder extending about at least a portion of the outer circumferential surface. The shoulder includes a first surface configured to form a seal against a valve body and a second surface substantially opposite the first surface. The seat ring assembly also includes a seat ring retainer configured to be attached to the valve body and to apply a force to the second surface to hold the first surface to form the seal against the valve body.

US Classification:

251359

Abstract:

A valve seat apparatus for use with fluid valves is described. An example valve seat apparatus includes a seat ring having an outer surface that includes a first annular recess and a second annular recess adjacent the first annular recess to form a stepped profile. A seal assembly is disposed within the first groove and a retainer is disposed in the second annular recess to retain the seal assembly in the first annular recess of the seat ring.

International Classification:

F01L 3/10
B21D 51/16

US Classification:

251337, 2989012

Abstract:

A valve actuator assembly includes a housing having a diaphragm plate and diaphragm disposed within the housing. A stem projection downwardly extends from a bottom surface of the diaphragm plate, and the stem projection is coupled to an actuator stem disposed along a longitudinal axis. A guide member has a top wall and a center aperture that receives the stem projection, and the top wall is biased into engagement with the bottom surface of the diaphragm plate by a spring. The guide member also has a side wall that downwardly extends from the top wall, and an outer surface of the side wall is adapted to engage an inner surface of a spring housing to limit displacement of the diaphragm plate and the actuator stem in a direction normal to the longitudinal axis.

International Classification:

F16K 322

US Classification:

137244, 1510405, 1510416, 1376253, 13762537, 251205, 251324

Abstract:

The seal assembly is disclosed for use with a valve having a trim cage with an inner surface extending along in axis and a plug sized to fit inside the trim cage inner surface, wherein the plug is adapted to move along the axis thereof. A seal ring is attached to an upstream portion of the cage to effectuate a seal with the plug. The plug is equipped with a wiper seal that cleans or otherwise removes debris from the seating surface of the seal ring, an interior surface of the seal ring and an interior surface of the cage during both the opening and the closing of the valve. Thus, the valve is self-cleaning. Further, the wiper seal delays throttling action through the valve until the plug has moved a substantial distance away from the seating surface of the seal ring which reduces high pressure abrasive flow against the seating surface of the seal ring to reduce wear on the trim set.

International Classification:

F16K 27/04
F16K 27/00

Abstract:

A flow control valve includes a valve body having an inlet, an outlet, and a flow path connecting the inlet and the outlet. A trim assembly is disposed in the flow path and includes a valve seat and a cage. The cage includes a body and a central cavity defined by the body. A control member is movable in the central cavity of the cage between an open position, in which the control member is spaced away from the valve seat, and a closed position, in which the control member engages the valve seat. The body has a non-circular longitudinal cross-section.

International Classification:

F16K 47/08
F16K 3/26

Abstract:

A control valve includes a cage is disposed within a valve body adjacent to a valve seat. The cage includes a first sleeve and a second sleeve. The first sleeve includes a first circumferential wall having a first inner surface, a first outer surface, and a first longitudinal axis. The first sleeve also includes a first plurality of openings disposed in the first circumferential wall. The second sleeve includes a second circumferential wall having a second inner surface and a second outer surface and a second longitudinal axis. The second sleeve also includes a second plurality of openings disposed in the second circumferential wall. The first outer surface of the first circumferential wall is tapered at a first angle relative to the first longitudinal axis, and the second inner surface of the second circumferential wall is tapered at a second angle relative to the first longitudinal axis.

Paul T. Alman - Marshalltown IA, US

International Classification:

F22G 5/12

Abstract:

A spray nozzle assembly has a housing with a body and cap flange secure to the body to define a bore within the housing. A first aperture is formed through the body and intersects the bore and a second aperture is formed through the cap flange and intersects the bore. A nozzle sleeve is disposed within the bore and has a solid, unitary sleeve body. First and second fluid passages are formed through the sleeve body. The first fluid passage is in fluid communication with the first aperture and a first exit aperture in an end of the sleeve body. The second fluid passage is in fluid communication with the second aperture and second and third exit apertures in the end of the sleeve body, which are positioned on opposite sides of the first exit aperture. A portion of the second fluid passage surrounds the first fluid passage.
