US Patent:

20110240126, Oct 6, 2011

Filed:

Mar 28, 2011

Appl. No.:

13/073609

Inventors:

David Lymberopoulos - Houston TX, US
Benjamin R. Matthews - Missouri City TX, US

International Classification:

F16K 1/00
F16K 31/12

US Classification:

137 1, 251 12, 251337, 251321

Abstract:

Embodiments of a method of operating a safety valve and a safety valve system are provided. The valve system includes a valve, an actuator, a mechanical override, and an indicator. The actuator includes a fail-safe mechanism and the indicator is configured to indicate whether the fail-safe mechanism is operable during use of at least one of the actuator and the mechanical override. In one embodiment, a method of operating the safety valve includes actuating the valve into an open position and sending a signal to indicate that the fail-safe mechanism is operable to move the valve to the closed position, while the valve is in the open position.

Inventors:

David Lymberopoulos - Houston TX, US
Benjamin R. Matthews - Missouri City TX, US

International Classification:

E21B 34/06
G05D 7/06

US Classification:

166373, 1374875, 137 1

Abstract:

A safety valve control system may include a remotely operable control assembly, a first transducer, a valve assembly, and a compressor assembly in communication with the control assembly. The control assembly is operable to actuate the pump and valve assemblies to supply fluid to actuate the safety valve into open and closed positions, in response to one or more signals received from the first transducer. A method of operation may include maintaining the safety valve in an open or closed position while sensing a physical property with the control system; communicating a signal corresponding to the sensed physical property to the control system; and automatically closing or opening the safety valve in response to a comparison of the sensed physical property to a pre-set condition.
