Zusammenfassung: | 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. |
