20120291883, Nov 22, 2012

Filed:

May 23, 2012

Appl. No.:

13/479166

Inventors:

WILLIAM K. FILIPPI - HUNTINGTON BEACH CA, US

International Classification:

F16K 21/18

US Classification:

137409

Abstract:

A fluid level control mechanism comprising a reservoir assembly, a flow line assembly, and a resilient force assembly. The flow line assembly has a main flow line capable of passing a fluid, a diverter flow line, and a diverter valve. The diverter valve is connected to a lower end plate of the reservoir assembly via a lever arm, such that the reservoir assembly is capable of sliding along the length of the main flow line in response to a fluid level. Downward movement of the reservoir assembly opens the diverter valve and upward movement of the reservoir assembly closes the diverter valve. The resilient force assembly is attached to the main flow line and the reservoir assembly and is capable of exerting a vertical force against the reservoir assembly to close the diverter valve.

Abstract:

A fluid level control mechanism comprising a float assembly, a flow line assembly, an upper centralizer, and a lower centralizer. The float assembly has a cylindrical outer float tube and a cylindrical inner float tube connected by upper and lower end plates to form a sealed cavity. The flow line assembly has a main flow line capable of passing a fluid, a diverter flow line, and a diverter valve. The diverter valve is connected to the lower end plate of the float assembly via a lever arm, such that the float assembly is capable of sliding along the length of the main flow line in response to a fluid level. Downward movement of the float assembly opens the diverter valve and upward movement of the float assembly closes the diverter valve. The upper and lower centralizers center the mechanism within a well bore.
