Actuator For Well-Head Valve Or Other Similar Applications And System Incorporating Same

View page
US Patent:
6953084, Oct 11, 2005
Filed:
Jan 10, 2003
Appl. No.:
10/340017
Inventors:
Kevin E. Greeb - Fort Collins CO, US
Jeffrey T. Stewart - Greeley CO, US
Grant A. Sweer - Fort Collins CO, US
Joel W. Kleckler - Rockton IL, US
Roger T. Hybeck - Fort Collins CO, US
Assignee:
Woodward Governor Company - Fort Collins CO
International Classification:
E21B034/02
US Classification:
166 664, 166 667, 166 971, 1663321
Abstract:
An electrical actuator is particularly suited for driving a wellhead valve for regulating the flow of natural gas from a production well. The electrical actuator can be driven using the existing local power supply in wellhead valve systems, typically a solar panel and a battery. The electrical actuator may include a gear reduction train, a brake and a manual input override with clutch protection. The electrical actuator can be configured in three different operational modes that provides a predetermined position upon power loss including fail-bias fixed, fail open and fail bias closed.

Pressurized Seal Arrangement

View page
US Patent:
7059418, Jun 13, 2006
Filed:
Nov 18, 2003
Appl. No.:
10/715708
Inventors:
Kevin E. Greeb - Fort Collins CO, US
Jeffrey T. Stewart - Greeley CO, US
Wade A. Burdick - Windsor CO, US
Gary M. Bowman - Loveland CO, US
Assignee:
Woodward Governor Company - Fort Collins CO
International Classification:
E21B 34/02
US Classification:
166387, 166 971, 1663321, 1663344, 166386
Abstract:
A pressurized sealing arrangement suited for providing a seal between a valve stem and a valve body is provided. The sealing arrangement includes a piston that is restrained in and statically sealed to the valve body and which surrounds the valve stem. Contained within the piston is an annular seal packing that includes two sealing elements spaced apart by a spacer element. The piston includes a face acted upon by a process fluid flowing through the valve body in such a manner that the piston exerts pressure upon a lubricant cavity. The lubricant cavity is in fluid communication with the seal packing such that lubricant contained therein forms a lubricant ring around the stem. Lubricant is also thereby supplied to sealing elements of the packing seal. To prevent contamination of the seal packing, a removable cover is provided that encloses the piston and seal packing.

Fully Independent, Redundant Fluid Energized Sealing Solution With Secondary Containment

View page
US Patent:
7426936, Sep 23, 2008
Filed:
Mar 2, 2006
Appl. No.:
11/366299
Inventors:
Jeff A Gessaman - Fort Collins CO, US
Steven Charles Stumbo - Fort Collins CO, US
Kevin E. Greeb - Fort Collins CO, US
Wade A. Burdick - Fort Collins CO, US
Assignee:
Woodward Governor Company - Fort Collins CO
International Classification:
F16J 9/00
US Classification:
137312, 251214, 277320
Abstract:
A redundant sealing system with secondary containment for preventing leakage of fluid along a valve shaft is provided. The system comprises a first set of dynamic seals, a second set of dynamic seals, an auxiliary barrier fluid chamber, and a barrier fluid indicator. The first and second set of dynamic seals are in spaced relation to each other a distance equal to or further than a maximum stroke length of an actuatable valve stem. The auxiliary barrier fluid chamber is interposed between the first and second sets of dynamic seals. The barrier fluid indicator has a piston in a primary barrier fluid chamber. A first face of the piston is exposed to the auxiliary barrier fluid chamber. A second face of the piston is exposed to a barrier fluid and inhibited from fluid communication with the auxiliary barrier fluid chamber by a dynamic seal in the first set of dynamic seals.

Apparatus For Elimination Of Transient Pressure Spikes On Stiff Fluid Systems

View page
US Patent:
7464532, Dec 16, 2008
Filed:
Oct 25, 2005
Appl. No.:
11/258304
Inventors:
Kamran Eftekhari Shahroudi - Fort Collins CO, US
Kevin E. Greeb - Fort Collins CO, US
Assignee:
Woodward Governor Company - Fort Collins CO
International Classification:
F02C 7/22
F02C 7/232
US Classification:
60 39091, 60734
Abstract:
An apparatus for reducing pressure spikes in a fuel line having a shut-off valve is provided. The apparatus comprises a body housing a biasing member and a moveable separation member. The body has first, second, and third chambers. The first and second chambers are coupled to upstream and downstream sides of the fuel line, respectively. The third chamber is coupled to a return line. When the shut-off valve is open, the separation member is biased toward the first chamber and separates the first and second chambers. When the shut-off valve is closed, the separation member expands the first chamber and places the first chamber and the third chamber in fluid communication once the separation member has gained a significant speed. The expanded first chamber accumulates fuel and the third chamber accumulates and vents the fuel such that transient pressure spikes are reduced and unlikely to damage a turbine system.

Digital Closed Loop Proportional Hydraulic Pressure Controller

View page
US Patent:
8215329, Jul 10, 2012
Filed:
Feb 1, 2008
Appl. No.:
12/024148
Inventors:
Kevin E. Greeb - Fort Collins CO, US
Assignee:
Woodward, Inc. - Fort Collins CO
International Classification:
F16K 31/04
US Classification:
137 85, 137312, 1374875, 700282
Abstract:
A digitally controlled current to pressure converter (CPC) is provided. A digital CPC utilizes a digital controller and an onboard pressure transducer to accurately control the output pressure based upon an input analog control signal. The digital controller includes an anti-silting algorithm that provides an impulse movement of the three-way rotary valve of the CPC to loosen and flush away silt contamination from the valve. A redundant seal stack including an intermediate passage to the hydraulic drain ensures a low pressure drop across the outboard seal minimizing the potential for leakage and improving reliability of the CPC. The digital controller also includes redundancy and fault management algorithms that enable the use of multiple inputs and feedback signals for control of the CPC. Master/slave operation and transitioning is also provided by the digital controller.
