但有关人士指出，我国电动给水调节阀阀门业有可能利用后发优势实现跨越式发展。

But the personage points out , the development of electric water regulator valve industry might be possible to use the great-leap-forward development of advantage of backwardness .

在机组启动、冲转及机组并网至15%负荷阶段，给水泵维持在最低安全转速下运行，汽包水位由低负荷给水调节阀自动控制；

During unit startup and load is lower than 15 % , drum level is controlled by feedwater control valve , feedwater pump remains at minimum safety speed ;

电站锅炉给水调节阀的阀杆密封采用柔性石墨填料，既降低了摩擦力，又为调节阀的运行节约了能源。

The stem seal of a feed water control valve uses expanded graphite packing in order to produce friction and to economize on energy for the control valve working .

负荷在25%至50%阶段时，给水调节阀已完全关闭，主给水电动门已完全打开，水位控制已全由单台给水泵承担；

When load is between 25 % and 50 % , control valve is closed fully , and main motor-operated-valve is open fully , drum level is controlled by one pump ;

15%至25%负荷阶段，给水调节阀由函数模块按照一定的速率自动平滑关闭，主给水电动门自动打开，汽包水位控制方式自动无扰切换为给水泵自动控制；

When load is between 15 % and 25 % , feedwater control valve is closing at fixed speed determined by function module , main motor-operated-valve is opened automatically , control mode of drum level is transferred to feedwater pump automatically and bumplessly ;

以100MW锅炉主给水系统调节阀的改进设计，论述了对高压差调节阀的设计原则，以及DN225；

According to the design improvement on feed-water control valve of a 100 MW boiler , this thesis illustrates the principle on designing high differential pressure control valve , a new thought and method on designing the linetype of the disc of a DN225 ;

该系统包括给水泵控制、调节阀阀位控制以及安全保护和报警。

The system consists of feedwater pump control , adjusting valve level control , safety and alarm devices .

该给水系统中的给水调节采用的是既调阀又调泵的调节方式，给水泵调速是为了控制给水调节阀压降恒定。

In this feedwater syetem , the control of the feedwater is achieved by regulating both the pump and the feedwater regulating valve , the aim of regulating the pump 's rotation speed is to keep the pressure drop of the feedwater regulating valve invariable .

由我国承建的印度某电厂两台300MW发电机组，其给水系统设三台电动调速给水泵、一个低负荷给水调节阀（用于低负荷水位控制）和一个电动主闸阀。

Both units ( 2X300MW ) of one power plant in India , designed and constructed by China , employ feedwater system composed of three 50 % capacity motor driven feedwater pumps , one low load feedwater control valve and one main motor-operated-valve .

同时，对给水控制的经济性进行的分析，提出了自己思考的改进办法，并设计了给水调节阀的自动切换回路。

At the same time , a automatic switch design for feed-water modulate valves is finished .
