您要查找的是不是：
- operating valve stem jaw 操作阀柄爪
- 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。
- Operating Principle: The diaphragm valve is a handwheel-operated valve, utilizing a two-piece stem separated by non perforated diaphragms. These diaphragms prevent leakage along the valve stem. 运转原理：膜板阀是一种手轮型阀门，它采用两个由非穿孔横膈膜隔开的阀杆。这些横膈膜防止了沿着阀杆的泄漏。
- 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。
- Pack a valve stem. 扎好活门塞

- Inspect for scuffed or bent valve stems. 检视气门杆是否擦伤或弯曲。
- 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。
- In all designs, the valve stem normally serves as a piston rod with disc fastened directly to them. 在所有结构中，阀杆通常作为活塞杆，阀瓣直接固定在阀杆上。
- Loosen and remove the diaphragm lock nut and lock washer, pressure plate and diaphragm from the valve stem. 松开和拆卸隔膜锁紧螺母和锁紧垫圈，从阀杆上往下压阀盘和隔膜。
- The leading option, already offered on some models, is a sensor housed in a fob inside a tire, behind the valve stem. 最佳的选择就是，将侦测器设在活门杆后方、车胎内侧的传送器中，这个方法现在已经正在使用。
- Slight tapping with a mallet may be required, but do not change the valve stem position. 如果需要，用木槌轻轻敲打，但是不要改变阀杆位置。
