High Energy Loss Fluid Control Device

US Patent:
6161584, Dec 19, 2000
Filed:
Nov 1, 1999
Appl. No.:
9/431747
Inventors:
Kent R. Hemme - Erie PA
Allan K. Shea - Erie PA
Assignee:
Copes-Vulcan, Inc. - Lake City PA
International Classification:
F16K 4708
US Classification:
13762537
Abstract:
A high energy loss fluid control device includes a plurality of annularly-shaped discs stacked one upon another and a reciprocal plug in slidable contact with the discs. The discs form a plurality of flow passageways extending between an inlet and an outlet located at the inner and outer peripheries of the discs. Each of the flow passageways has a plurality of sections connected with right-angle turns. A first one of the sections is radially extending toward the inlet to cause fluid to act upon itself and expend energy by turbulent interaction. Immediately downstream of the first section, a second one of the sections is radially extending toward the outlet. The second section is generally straight and of a length adequate to regain control of fluid velocity by true frictional losses. The passageways can be formed by stacks of discs that cooperate to fully define intermediate passageways or by alternating flow-path discs and separator discs that cooperate to form the passageways.

High Energy Loss Fluid Control Device

US Patent:
6039076, Mar 21, 2000
Filed:
Jun 30, 1998
Appl. No.:
9/109122
Inventors:
Kent R. Hemme - Erie PA
Allan K. Shea - Erie PA
Assignee:
Copes-Vulcan, Inc. - Lake City PA
International Classification:
F16K 4708
US Classification:
13762537
Abstract:
A high energy loss fluid control device includes a plurality of annularly-shaped discs stacked one upon another and a reciprocal plug in slidable contact with the discs. Each of the discs has an inner periphery, an outer periphery, and a plurality of flow passageways extending between an inlet and an outlet located at the inner and outer peripheries. Each of the flow passageways have a plurality of sections connected with right-angle turns. The sections alternate between extending in a circumferential direction and a radial direction. Each passageway has an expanding cross-sectional area but each section has a constant cross-sectional area. A first one of the sections is radially extending toward the inlet to cause fluid to act upon itself and expend energy by turbulent interaction. Immediately downstream of the first section, second one of the sections is radially extending toward the outlet. The second section is generally straight and of a length adequate to regain control of fluid velocity for true frictional losses.

Metallic Seal For High Performance Butterfly Valve

US Patent:
4796857, Jan 10, 1989
Filed:
Dec 3, 1987
Appl. No.:
7/128282
Inventors:
William R. Hayes - Cincinnati OH
Allan K. Shea - Erie PA
Assignee:
White Consolidated Industries, Inc. - Cleveland OH
International Classification:
F16K 122, F16K 2500
US Classification:
251173
Abstract:
A high performance butterfly valve utilizing a thin sheet metal annulus to provide sealing between a valve casing and a rotary disc type valving member. The design of the sealing element provides for a self-sealing at all pressures, with augmentation of the sealing action as a result of applied pressure differential. As maximum stresses in the thin metal sealing element are approached, the element becomes supported at an intermediate region, enabling effective performance at both low and high pressure limits.

Fluid Trim Apparatus And Method

US Patent:
7195034, Mar 27, 2007
Filed:
Jul 19, 2005
Appl. No.:
11/183898
Inventors:
Allan K. Shea - Erie PA, US
Assignee:
SPX Corporation - Charlotte NC
International Classification:
F16K 47/08
US Classification:
13762537, 138 42
Abstract:
A noise reducing apparatus and method for handling of fluid comprises a plurality of discs stacked on one another, each disc having a radially inner periphery and a radially outer periphery, and a plurality of fluid flow channels defined on at least some of the discs and extending from the inner periphery to the outer periphery. One or more sound reducing material elements are disposed to extend across at least some of the fluid flow channels so that fluid flowing through the channel passes through the sound absorbing material. Alternatively, a plurality of sound absorbing wafers are disposed in between adjacent discs and form a respective wall of the flow channels with respect to the flow channel of an adjacent disc.

Spring Assisted Multi-Nozzle Desuperheater

US Patent:
5607626, Mar 4, 1997
Filed:
Aug 18, 1995
Appl. No.:
8/516567
Inventors:
Timothy E. Kunkle - McKean PA
Allan K. Shea - Erie PA
Richard F. Kuntz - Erie PA
Assignee:
Copes-Vulcan, Inc. - Lake City PA
International Classification:
B01F 304
US Classification:
261 27
Abstract:
A steam desuperheater has a body extending into a steam line and is operated by a controlled variable water pressure source responding to the amount of superheat in the steam line. As the pressure of the supply line is increased above a predetermined level greater than the steam pressure in the steam line, a piston moves up against a calibrated spring to progressively uncover a plurality of spray openings so that increasing water pressure results in an increasingly greater amount of water sprayed into the steam line.

Quarter Turn Valve

US Patent:
4712768, Dec 15, 1987
Filed:
Oct 23, 1986
Appl. No.:
6/922782
Inventors:
Leroy E. Herr - Erie PA
Allan K. Shea - Erie PA
Timothy E. Kunkle - McKean PA
Assignee:
White Consolidated Industries, Inc. - Cleveland OH
International Classification:
F16K 122
US Classification:
251305
Abstract:
The disclosure is directed to a high performance butterfly control valve which may be applied and utilized in critical high pressure and/or high performance operation environments. In accordance with the invention, the vane of the butterfly valve is formed to include first and second diametrically opposed, asymmetrical projections, each extending from the periphery of the vane and each including a plurality of fluid control passages formed therethrough. The projection adjacent the downstream rotated periphery of the vane is formed to a generally smooth, streamlined configuration to minimize the overall volume of the vane, and to facilitate a smooth, turbulence free flow when the valve is in the full open position. Moreover, the projection adjacent the upstream rotated periphery of the vane is formed to a length of extension which is greater than the length of extension of the diametrically opposed projection. The asymmetrical projections and fluid control passages provide low angle flow control with an overall vane configuration that affords a practical maximum full open valve fluid flow.
