氢氮无级调节自动化混合配气装置
Stepless adjustment of hydrogen and nitrogen mixed gas distribution automation devices
一、 工作原理；本装置以氢气为原料，通过调节阀调节，加入纯氮气中，获得稳定的具有一定比例的氢氮混合气。在按需调准。
二、设备主要组成及功能；
1 调节阀；。
2 氢分仪；。
3 智能显示调节仪；
4 电气转换器；
5 混合罐；。
7 配比流量计；
三、工艺流程；
原氢气经阀，调节阀调节加入纯氮气中，配比气经混合罐混合，混合后的配比气经氢分仪分析，显示氢的百分比含量，氢分仪把氢的百分比含量转换成电信号，智能显示调节仪把氢分仪的电信号与设定值相比较计算，计算结果转换成电信号驱动电气转换器，转换成气压信号，调节阀阀芯的行程和气压信号成正比，从而达到调节混合比例的功能。
Stepless adjustment of hydrogen and nitrogen mixed gas distribution automation devices
First, the working principle;
This means the hydrogen gas as raw material, by adjusting the valve control, with pure nitrogen gas, stable gas mixture of hydrogen and nitrogen with a certain proportion. On-demand alignment.
Second, the major equipment components and functions;
Control valve;.
2 hydrogen partial instrument;.
3 smart display regulator;
4 electrical converters;
5 mixing tank;.
7 ratio meter;
Third, the process;
Raw hydrogen through the valve, regulating valve adjustment with pure nitrogen, the ratio of the mixed gas tank mixing ratio of hydrogen gas through the points analyzed mixed, show the percentage of the content, the percentage content of hydrogen partial hydrogen analyzer converts hydrogen into electricity signal, the smart display regulator electrical signal with the set value compared to the hydrogen partial meter calculation, the results converted into electrical signals for driving electric converter, converted into a pressure signal, adjusting the air pressure signal proportional to the stroke of the valve spool, thereby to regulate the function of the mixing ratio.
