Appl. No.:

5/841225

Inventors:

John A. Bond - Houston TX

Assignee:

ACF Industries, Incorporated - New York NY

International Classification:

F16K 300

US Classification:

251328

Abstract:

A non-floating seat structure for an expanding gate valve in which a seat ring is pressed within a body recess and a sealing member is inserted in a groove between a rear face of the seat ring and an opposed wall defining the recess to form a fluid-tight barrier. The groove for the sealing member is of a generally rectangular cross-section and is formed by a counterbore in the valve body and a rearwardly extending inner lip on the seat ring which abuts the recess wall when the seat ring is pressed within the body recess.

International Classification:

E21B 33064
E21B 3404
E21B 4312

US Classification:

166363

Abstract:

The specific embodiment comprises a valve piston mounted on a shaft that is slidably disposed within an aperture in the lower housing of the blowout preventer. The valve piston and shaft may be extended into the central passage of the BOP in an open position through the use of a hydraulic operator assembly. When the valve piston and shaft have been extended into the open position, the wellbore gases enter into the annular space between the shaft and the aperture through the lower housing of the BOP. The wellbore gases are then vented from the aperture through an open vent conduit to the outside of the BOP. The hydraulic operator assembly is spring biased to keep the valve piston and shaft in closed position whenever the hydraulic operator assembly is not activated. The valve piston will therefore automatically close whenever there is a loss of hydraulic control. In normal operation, the hydraulic operator assembly will keep the valve piston and shaft in open position until the wellbore gases have been vented.

Assignee:

ACF Industries, Incorporated - New York NY

International Classification:

F16L 700

US Classification:

137375

Abstract:

A floating seat ring for a gate valve structure has an external pressure source to move the seat ring into engagement with the gate valve. A pocket for the seat ring is formed by a counterbore in the valve body and a tubular insert is inserted within the valve body bore extending within the seat ring. This inner end portion of the tubular insert defines with the counterbore the pocket for the seat ring for floating back and forth movement. An external pressure source is in fluid communication with the pocket behind the seat ring to move the seat ring outwardly.
