valve module

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;

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；

The hardware of AMT control system design was described, including the main control module, the sensor signal processing module, the magnetic valve drive module, power module and communication module.

Development of EPA High Speed Communication Module for Intelligent Valve Positioner

智能阀门定位器EPA高速通信模块的开发

The CAD software for a proportional valve and its working circuit is programmed by Visual Basic 6.0 and OOP ( object-oriented programming). The software includes a module for the selection and calculation of a proportional valve;

采用VISUAL BASIC6.0语言和面向对象的编程思想，开发了比例阀及其工作回路CAD软件。

Master control module used watch-dog timer control chips can achieve three-axis control in the meantime with the software: Module outputs 0-10V analog voltage to control the proportional solenoid valve to produce the necessary cutting pressure, so as to enhance cutting precision to improve cutting yields.

主控模块采用专用看门狗定时器芯片，配合软件可同时实现三轴控制，模块输出0-10V模拟量电压，控制比例电磁阀产生所需要的切割压力，从而提高切割精度及切割的成品率。
