摘要： A system, in certain embodiments, includes an annular ball valve seat including an annular spring, which biases the annular ball valve seat axially. More specifically, in certain embodiments, the annular ball valve seat includes a main body section, a lip section extending from the main body section, and a seat groove between the main body section and the lip section, wherein the first annular spring is disposed within the seat groove. A first leg of the annular spring biases the lip section in a first axial direction and a second leg of the annular spring biases the main body section in a second axial direction opposite the first axial direction. The annular ball valve seat is configured to be disposed within a ball valve, on either side of a ball of the ball valve. The particular design of the annular ball valve seat enables pressure within a body cavity of the ball valve to be self-relieving.

摘要： A ball valve positioned between a first line and a second line includes a housing and a ball disposed a ball disposed within the housing. The ball includes a bore and is configured to rotate between an open position and a closed position. The ball valve also includes an annular seat disposed between the housing and the ball. The annular seat includes a first annular sealing ring extending circumferentially about a radially-outer surface of the annular seat and an axially-extending passageway extending through the annular seat to enable fluid flow from a valve cavity to an annular space between the annular seat and the housing. The first annular sealing ring, the axially-extending passageway, and the annular space facilitate movement of the annular seat away from the ball as the ball rotates from the closed position toward the open position.

摘要： 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.

摘要： A ball valve includes a body and a ball subassembly. The body includes a first bore extending partially through the body from a first flange of the body along a first axis, the flange defining an opening, a second bore extending in along a second axis from the first bore to a second flange, wherein the second axis is transverse to the first axis, and a third bore extending along the second axis, opposite the second bore, from the first bore to a third flange. The ball subassembly is configured to be inserted into first bore of the body through the opening. The ball subassembly includes a ball having a ball bore extending through the ball. The ball is configured to rotate about the first axis to open and close the ball valve such that the ball bore is substantially aligned with the second axis when the ball valve is open, and wherein the ball bore is substantially transverse to the second axis when the valve is closed.

摘要： A ball valve includes a housing, a ball disposed within a cavity of the housing and configured to rotate between an open position and a closed position. The ball valve also includes an annular seat assembly positioned between the housing and the ball, and the annular seat assembly has an annular seat body having a ball-contacting surface configured to contact the ball and having an annular groove. The annular seat assembly also has an annular seal positioned within the annular groove, and the annular seal is configured to contact and to form a seal between the annular seat body and the housing and enables the annular seat body to move relative to the housing to automatically relieve a cavity pressure within the cavity across the annular seat assembly into an upstream bore of the housing.
