A mechanical advantage makes large valve operation easier and faster.

其优异的机械特性使得采用锥齿轮的阀门操作更加容易和快速。

The valve has been used in metallurgy, textile and oil industries with good results.

该阀门已应用于冶金、纺织和石油等行业，效果良好。

Positioner is used to control or throttle flow by modulating the air to the actuator in response to an external 4-20 milliamp control signal input which is converted to a proportional 3-15 psi pneumatic signal used by the positioner.

当外部4~20毫安控制信号输入转换成线性3~15 psi气动信号输入被采用后，定位器通过调节执行器气源流量来实现控制和调节阀门流量。

Positioner is used to control or throttle flow by modulating the air to the actuator in response to an external 4-20 milliamp, 0-5 VDC, or 0-10 VDC control signal input which is converted to a proportional 3 - 15 psi pneumatic signal used by the positioner.

当出现4~20毫安，0~5伏直流电，或0~10伏直流电控制信号输入时，将其转换成能用于定位器的3~15 psi线性气动信号后，这种定位器通过调节执行器气源流量来控制或调节阀门的流量。

For cylinders equipped with residual pressure valves, one evacuation under vacuum at 150 millibar is sufficient if the pressure is positive.

对于装有剩余压力阀门的气瓶，如果瓶内剩余压力是正压，把它抽真空到150 mbar 以下就可以了；要么就全面分析各个容器的残留气体。

Centrifugal energy saving analysis and measures: 1 improve the efficiency of centrifugal pumps a first step, in the selection of comparison, when many suppliers Selection program, in considering the cost-effective choice as far as possible under the premise of efficient programs; the second step , accredited professionals must Mill producers, affecting the pump efficiency of the key components such as impellers, pump body, pump cover, diversion devices, such as the manufacture of quality producers, especially for the airfoil impeller , outlet angle, leaves the sub-degrees, the shape of flow channel, to control the quality of finish, etc., so that products are delivered in the current production under the conditions of highly efficient products; the third step, the scene in the production of installation and debugging process, pump to ensure a solid foundation, with the driving machine for good, before and after valve flexible piping layout design is reasonable, on-site control is feasible and safe, the complete and accurate monitoring instrumentation to ensure that pump operation can carry out real-time monitoring; fourth step , are at long-term operation of water pumps necessary to pay attention to the equipment inspection and found anomalies reflect real-time reporting, in the normal minor repairs, overhaul cycle, to deal with the replacement of wearing parts inspection to ensure the pump's long-term safe and efficient operation.

第一步，在选型时多比较各供应商的选型方案，在考虑性价比的前提下尽量选用效率高的方案；第二步，派驻一定的专业人员驻厂监制，对影响水泵效率的关键零部件如叶轮、泵体、泵盖、导流器等的制造质量进行监制，尤其对叶轮的翼形、出水角、叶片的分度、流道的形状、光洁度等质量进行控制，使交付的产品是在当前的生产条件下的高效率的产品；第三步，在生产现场的安装调试过程中，要保证泵的基础牢靠，与驱动机对中良好，前后阀门开关灵活，管道布置设计合理，现场控制安全可行，各运行监控仪表齐全准确，保证泵的运行过程能够进行实时监控；第四步，是在水泵的长期运行中要注意对设备的点检，发现异常情况即时反映汇报，在正常的小修、大修周期中，应对各易损件进行检查更换，保证泵的长期高效安全的运行。

Should a standing column well design be misapplied, leaving out critical shut-off valves for example, the result could be an extreme loss in efficiency and thereby cause operational cost to be higher than anticipated.

如果一个常设栏目和设计被误用，留下了关键的关闭阀门，例如，结果可能是一个极端的效率损失，从而导致运营成本比预期高。

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。
