与流体阀的致动器一起使用的偏置装置
摘要：
一种与流体阀的活塞致动器一起使用的偏置装置，该偏置装置包括管状基座元件、管状定位元件、管状基座支架以及设置于所述管状基座元件的外部环状凸缘与所述管状基座支架的外部环状凸缘之间的偏置元件。所述管状定位元件部分地设置于所述管状基座元件之中，所述管状定位元件穿过所述管状基座元件的内部凸缘上的开口。所述管状定位元件部分地设置于所述管状基座支架之中，所述管状定位元件穿过所述管状基座支架的内部凸缘上的开口。所述偏置元件抵靠所述管状基座元件的所述外部环状凸缘以及所述管状基座支架的所述外部环状凸缘。
摘要（英）：

A biasing device for use with a piston actuator of a fluid valve includes a tubular seat member, a tubular retention member, a tubular retention bracket, and a biasing element disposed between an external annular flange of the tubular seat member and an external annular flange of the tubular seat bracket. The tubular retention member is partially disposed within the tubular, seat member, the tubular retention member passing through an opening in the inner flange of the tubular seat member. The tubular retention member is partially disposed within the tubular seat bracket, the tubular retention member passing through an opening in the inner flange of the tubular seat bracket. The basing member is seated against the exterior annular flange of the tubular seat member and against the exterior annular flange of the tubular seat bracket.
