    • A valve comprises a valve member (12) engageable with a valve seat (11) provided in a valve body (19, 20), an annular seal (28) slidably supported on the valve member (12) or adjacent the valve seat (11) and having an axial end face which is sealing engageable with the valve seat or valve member respectively on engagement of the valve member with the valve seat, the axial end face providing at least some of the sealing between the valve member and valve seat. In use the differential in pressure existing between the upstream side of the valve member, and thus closed space (29), and the downstream side of the valve member when the valve is closed produces an axial force on the seal (28) to drive it axially into sealing engagement with the valve seat or valve member respectively. Any wear of the axial end face of the seal (28) is accommodated by such axial movement.
    • 阀包括可与设置在阀体(19,20)中的阀座(11)接合的阀构件(12),可滑动地支撑在阀构件(12)上或邻近阀座(11,20)的环形密封件(28) ),并且具有轴向端面,所述轴向端面分别在所述阀构件与所述阀座接合时可与所述阀座或阀构件接合,所述轴向端面提供所述阀构件和阀座之间的至少一些密封。 在使用时,阀构件的上游侧与封闭空间(29)之间存在的压力差和当阀关闭时阀构件的下游侧在密封件(28)上产生轴向力以驱动阀 轴向地分别与阀座或阀构件密封接合。 通过这种轴向移动来容纳密封件(28)的轴向端面的任何磨损。
