US Patent:

Filed:

Jan 3, 2011

Appl. No.:

12/983806

Inventors:

Mircea Balan - Moore OK, US
Steven Burrows - Oklahoma City OK, US

Assignee:

CAMERON INTERNATIONAL CORPORATION - Houston TX

International Classification:

F16K 5/06

US Classification:

137 1, 25131501

Abstract:

The disclosed embodiments include systems and methods for energizing a ball valve seat assembly. In particular, the disclosed embodiments are directed toward energizing devices that generate linear or substantially linear energizing forces. In other words, as a seat of the ball valve translates axially with respect to a ball of the ball valve, the resulting energizing force that biases the seat ring back toward the ball is substantially directly proportional to the amount of axial translation. In certain embodiments, the linear energizing device includes an annular cantilevered v-shaped spring having a generally constant cross-sectional profile, including a pair of legs extending from a curved end.

International Classification:

F16K 5/06
B21D 53/00

US Classification:

251314, 29890124

Abstract:

The disclosed embodiments include systems and methods for retaining a seat insert of a ball valve in place within a seat ring of the ball valve. In particular, the seat insert is an annular ring having a tapered section on an outer wall of the annular ring. The tapered section of the seat insert is configured to mate with a shoulder in an outer surface of a profiled groove of the seat ring. The seat insert snaps into the profiled groove with the shoulder, thereby preventing axial movement of the seat insert with respect to the profiled groove of the seat ring. In addition, a locking ring also fits within the profiled groove of the seat ring to prevent axial and radial movement of the seat insert with respect to the profiled groove of the seat ring. More specifically, once the seat insert has been snapped into place within the profiled groove of the seat ring, the locking ring is also inserted into the profiled groove of the seat ring.

International Classification:

E21B 29/00
E21B 31/16
E21B 33/06

Abstract:

A tubular string is cut using a severing system deployed from the rig floor inserted through the BOP into the tubular string and landed in a fit-for-purpose wellhead. The cutting operation forms an excess tubular string and a remaining tubular string. Once cut, the excess tubular string is removed through the BOP. The system and its use eliminates the need to perform a cutting operation at the wellhead by personnel under the rig floor and the need for removal of the BOP thus reducing cost, saving time, and eliminating the inherent risk attendant with these operations.
