阀门

When installed, easy and unobstructed access to the valve handwheel and metering ports for adjustment should be provided.

安装时，要保证能够容易或无障碍地接近阀门手轮和进行调节的测量端口。

Add these weights to valve and handwheel weights.

将这些重量加在阀门和手轮重量上。

The system structure configuration of hardware and the design of software are described in detail.

详细介绍了各阀门站的硬件结构及系统软件设计。

Valves to be Hattersley Heaton design.

阀门为HH设计。

This application calls for a much larger Hawse pipe valve.

这个应用就要求更大的锚链管道阀门。

This drawing shows a typical configuration of a Red Valve Hawse pipe valve.

此图显示美国红阀公司锚链管道阀门的标准结构。

The Hawse pipe valve's split-sleeve design allows for easy installation that does not require movement of the heavy chain.

锚链管道阀门的分体式套管设计就使得安装简便，不需要移动沉重的链条。

In the application shown on the front left , the customer uses a cable-style anchor, which requires a smaller Hawse pipe valve.

在上一页所显示的应用中，用户采用了缆索式锚链，因此需要更小一点的锚链管道阀门。

Red Valve has installed numerous Hawse pipe valves worldwide since the late 1980s.

从1980年代开始，美国红阀公司就在世界上安装了无数的锚链管道阀门。

More complicated designs have been used in the past but have not had the structural integrity nor the watertight sealing capabilities of the Red Valve Hawse pipe valve.

以前所采用的设备则复杂得多，但是反而缺乏结构的整体性，也无法实现象美国红阀公司锚链管道阀门一样的不透水的紧密密封。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
