您要查找的是不是:
- bottom valve failure 底阀泄漏
- There is no need of bottom valve in pipeline, only to ensure certain priming oil in pump body before work. 管路中不需底阀,工作前只需保证泵体内储有定量引油即可。
- The results show that the stress crrosion,wich is duo to the less leaking of the crrosion media in tower,cause the fastening bolt of valve failure. 结果表明,由于塔内腐蚀性介质的微量渗出,导致了阀门紧固螺栓的应力腐蚀断裂。
- NOTE: To prevent premature valve failure it is not recommended that the valve operate in the throttled position with more than 25 ft. pressure differential. 注意:为了避免阀门过早出现故障,建议当压降大于25英尺时阀门不要在节流位置运行。
- Failure of a control valve on the liquid line to a tank must be considered because a control valve failure may adversely affect the flow of material to a tank. 必须考虑储罐液体注入管线上的控制阀发生故障的情况,因为控制阀故障可能会对进罐的物料流量产生不利影响。
- There is no need of bottom valve in pipeline, only to ensure certain priming oil in pump body before work, which has not only simplified the pipeline system, but also improved working conditions. 管路中不需安装底阀,工作前只需保证泵体内储有定量引液即可。因此简化了管路系统,又改善了劳动条件。
- The valves are connected to dip tubes that run to the cylinder sides. The top valve will have the dip tube in the vapor and the bottom valve will have the dip tube in the liquid. 阀门上连接着汲取管,汲取管伸入到钢瓶内侧。上面的阀门的汲取管处在蒸气里,下面的阀门的汲取管处在液体里。
- A control valve failure may also cause the liquid level in a pressurized vessel feeding liquid to a tank to drop below the outlet nozzle, allowing vapor from the vessel to be pressured into the tank. 控制阀故障还会导致向储罐供液体料的压力容器液位降低到其出口管嘴以下,使得蒸气从压力容器压入储罐。
- The incidences of valve failure were 3.35%/patient-year for bovine valves, 1.52%/patient-year for porcine valves and 2.2%/patientyear for dura mater valves. 49例的51只生物瓣膜损破;损破率为2.;62%25病人-年;牛心包瓣的损破率为3

- They sent the enemy ship to the bottom of the sea. 他们把敌舰击沉。
- Rheumatic pulmonary valve failure 风湿性肺动脉瓣衰竭
- The child was sitting on the bottom stair. 那孩子正坐在楼梯最下面的一级上。

- I intend to get to the bottom of it. 这件事我打算寻根究底。
- He was always bottom of the class in maths. 他的数学成绩在班上总是垫底。
- The dregs have settled at the bottom of the bottle. 渣滓都沉到瓶底了。
- I fell right to the bottom of the stairs. 我从楼梯上一直摔到楼梯下面。
