阀门

Reduce the external leakage of valve valve packing system is the key to the material.

减少阀门外泄漏的关键在于阀门填料系统的材质。

Junction control valve is the key to both the pipeline's "head" is also the channel's "tail" and therefore play a vital valve position.

阀门是结控的关键，既是管道的&头&也是管道的&尾&，因此阀门扮演着至关重要的位置。

Life It is said that the durability of the valve is a valve key performance indicators, and has great economic significance.

& The main technical specifications of the valve&是由中国电动阀门网提供的国际阀门新闻，译文仅供参考。

Information by opening the valve D / A converted into analog signal output, is used to access indicator shows valve opening or connection to other control equipment.

阀门的开度信息通过D/A转换后变成模拟信号输出，用来接显示仪显示阀门开度或连接其他的控制设备。

1 The valve and the adjustment device of the boiler steaming-water pipe should be clearly marked, which should indicate the valve name, number, switch direction and working medium flowing direction, and the main regulating valve should have opening indicator.

9.7.1 锅炉汽水管道的阀门及调整装置应有明显标志，标明阀门名称、编号、开关方向以及工质流动方向，主要调节阀应有开度指示。

Gas valve body material selection Pressure gas pipeline under the reasonable use of the valve housing material selection, not only palace to meet the safe operation of pipeline and is able to reduce the cost and make the best use for the purpose.

三、燃气阀门的阀体材质选用根据燃气管线的使用压力合理选用阀门壳体材质，既宫满足管线的安全运行又能达到减少造价，物尽其用的目的。

The most important are as follows: Detection of type: valve stem seal leakage test and test; water valve tightness test; switch tightness test; the take-off safety valve Test; Detection Object: valve, the cut-off valve , safety valve, throttle valve, check valve, swing check valve, ball valve, regulating valve and other hollow pump body, valve body and housing, etc.; way valve connection: flange connection, threaded connection, welding connection; detection medium.

最重要的有以下几种：检测类型：阀门密封性试验及阀杆泄漏性试验；水中阀体密封性试验；开关密封性试验；安全阀的起跳值试验；检测对象：闸阀、截止阀、安全阀、节流阀、止回阀、摆动式逆止阀、球阀、调节阀和其他中空的泵体、阀体和壳体等；阀门联接方式：法兰联接、螺纹连接、焊接联接；检测介质。

Grab the handle of the valve, and turn it clockwise to unlock the door.

之后，爬上梯子来到阀门这里，顺时针转动阀门就能开启这扇门。

The characteristics of the inner flow field and outer sound field of a pneumatic valve sound generator is analyzed with its theoretical model,numerical simulation and experimental results.

在对气动阀门发声器的工作过程进行描述基础上，通过理论分析和数值计算与实验相结合的方法，分析了气动阀门发声器的内部流场和外部声场的特征。

Set of equipment should ensure the smooth flow of gas path (valve control, ozone generator to open, the valve must be opened) and the gas line, pipeline leak need to be taken, aiming to halt the measure.

整套设备应保证气路畅通（阀门控制时，臭氧发生器开起，阀门必须开通）并且各气路、管路需采取防漏、防堵措施。

This one mode pays close attention to network credence foundation of the businessman very much.

这一模式非常关注商人的网络信用基础。
