您要查找的是不是：
- metallic valve stem packing 阀杆金属填密
- Valve running thrust which represents 90% of the travel of the valve stem can be determined by adding stem load and stem packing friction. 阀门运行推力只是阀门阀杆行程力的90%25,因此测算阀门推力时,要加上阀杆负载和阀杆填料摩擦力。
- Valve rod with valve lids between bring fall airproof structure, Convenients for valve bring press replacing valve stem packing. 阀杆与阀盖之间带倒密封结构，便于阀门带压更换阀杆填料。
- Fire Test for Evaluation of Valve Stem Packing 阀门包装材料的防火试验
- Pack a valve stem. 扎好活门塞
- The connecting rod may drive a valve stem directly. 连杆可以直接带动阀门的把柄。
- Replaceable hose filter and valve stem seals for field reliability. 可更换软管过滤器和阀门阀杆密封,使得现场应用可靠行更高。
- For removal of valve stem seal and lower valve spring guide. 可用于拆卸汽门油封或降低汽门弹簧。
- Clean exposed portion of valve stem (Do not scratch). 清洗阀杆的外露部分(不要划伤)。
- A valve stem has broken off and effectively seized up the engine. 阀杆折断了，有效地阻止了发动机的运转。
- EXTENSION BONNET with a sufficient gas column to keep the stem packing away from the cold fluid. 扩展阀帽具有足够的气体柱,避免阀杆填料受到低温流体的影响。
- Stem bearing to assure concentric stem rotation, allowing stem packing to provide maximum sealing effectiveness. 阀杆轴承保证同轴阀杆的旋转,使得阀杆填料具有最大的密封效果。
- Stem is non-rotating, resulting in lower friction of all moving parts and longer stem packing life. 阀杆是不旋转的,这样就减少了所有运动部件的磨损,延长了阀杆填料的使用寿命。
- Inspect for scuffed or bent valve stems. 检视气门杆是否擦伤或弯曲。
- Valve stem 412 is dimensioned to attach to diaphragm 414, best seen in FIG. 2. 从图二可见，阀杆412设计成能与隔膜414接合。
- A tire tool or flat stock can be used to pry one part of the bead up over the rim flange( start near the valve stem). 可用轮胎工具或扁平的撬棒把轮缘的一端从轮辋辋圈上撬起。
- In a single-stage regulator, delivery pressure increases as cylinder pressure decays, because there is less gas pressure exerted on the valve stem. 在单级调整器里，输出压力随钢瓶压力的减小而增大，这是因为施加在阀门系统上的气体压力减小了。
- The valve is switched on or off with difficulty. Please clear the paint on the valve stem and add some lubricant. 阀件开关太困难,请清除阀杆上的油漆并加润滑剂。
- Turn the valve stem counterclockwise until the valve is fully open and will not turn any further. 逆时针旋转阀杆直到阀门全开为止，不要旋转过度。
- The valve stem with its grooved rings and positioning sleeve indicates the throttled position of the valve. 阀杆及其沟槽环和定位套筒显示阀门的节流位置。
