TB球阀手柄和锁定环组件
TB Ball Valve Handle and Locking Ring Kit

　　锁定环环绕在阀体周围，用于永久性固定在阀门上。当锁定装置从手柄上拆卸下来，并且保留环上的臂杆，这个环臂就挂在阀门下。这种功能简单的组件仅仅对阀门关闭的锁定有效，对于Chem-Aire排气阀是标准配置，或者可能附加在其它任何材质的Tru-Bloc阀门上。
　　The locking ring surrounds the valve body for permanent attachment to the valve. When the lock device is removed from the handle and retaining arm of the ring, the ring arm simply hangs beneath the valve. This single function kit is effective for valve-off lockout only, and is standard on Chem-Aire vent valves or may be added to other Tru-Bloc valves of any material.

球阀锁定盖
Ball Valve Lockout Cover

　　这种两件式模铸聚丙烯裂开蛤壳搭扣罩子，带有铰链固定环绕在普通的水平手柄或Tru-Bloc阀门上，是一种为了维护或操作锁定的简单的装置。这种罩子可以在手柄处于开启、关闭或任何节流位置下实现锁定，但是当罩子锁住了手柄位置后，有关阀门的状态就看不见了。三种尺寸的罩子中的一种通常用来传送到使用点，这是由于在未锁定时，罩子并不易于附着在阀门上。
　　This two-piece molded polypropylene split clamshell closure, which is hinged to fasten around the common handles of Horizon or Tru-Bloc valves, is a simple provision for maintenance or operations lockout. The cover can be locked with the handle in the on, off, or any throttling position, but when the cover is locked the handle position, relating ball posture, is not visible. One of three cover sizes is usually transported to the point of use, because a cover is not easily attached to the valve when it is unlocked.

TB Ball Valve-Mounted Lockout Kit w/Standard Plastic Handle

　　这种全塑料组件永久性安装在阀门上，可能被锁定在阀门开启或关闭的位置上。无论是锁定或未锁定，在任何时候阀门的手柄位置都可以清楚识别，包括节流位置。
　　This all-plastic kit, permanently mounted on a valve, may be locked in the on or off valve position. Whether locked or unlocked, the distinguishing handle position is clearly visible at all times, including throttling postures.

TB球阀 - 安装锁定组件和杠杆手柄和刻度板
TB Ball Valve-Mounted Lockout Kit w/ Lever Handle and Index Plate

　　这种组件由杠杆锁定手柄和刻度板组成，适合于配置球阀安装。它可以将阀门锁定在关闭位置或任何9个增量开启(每个增量为10^o)的位置，包括全开位置。这种手柄状态，与阀门状态完全一致，在任何时候都是可以观察到的。
　　This kit consists of a lever-lock handle and index plate, adapted to fit a ball valve mount. It provides for locking the valve in the off position or any of the 9 increments of opening (10^o each), including the full on position. The handle position, aligned with the fully on ball posture, is visible at all times.
