Valve structure The cut-off valve with pilot valve with manual control and electric control of two types.

阀门结构带先导球阀的截止阀有手动控制和电动控制两种类型。

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。

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。

Use of smart valve positioner not only can easily change the control valve flow characteristics, but also can improve the control of the quality control system.

采用智能阀门定位器不仅可方便地改变控制阀的流量特性，也可提高控制系统的控制品质。

Use of smart valve positioner not only can easily change the flow characteristics of control valve control system can also improve the quality of control.

采用智能阀门定位器不仅可方便地改变控制阀的流量特性也可提高控制系统的控制品质。

At Bell Labs, Shockley recognized early on that the solution to one of the technological nightmares of the day--the cost and unreliability of the vacuum tubes used as valves to control the flow of electrons in radios and telephone-relay systems ─ lay in solid-state physics.

在贝尔实验室，萧克利很早就体认到名为当代科技梦餍之一的问题─在收音机以及电话相关的系统中，如同控制阀门般控制电子流动、价格昂贵却又不可仰赖的真空管─其解决方法必定栖息于固态物理学之中。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
