sampling valve

Coal gas samplers in gas sampling bag were injected into gas chromatography by a six-port valve, separated by repacked column TDX-01 and determined by thermal conductivity detector ( TCD).

采集的煤气样品由6通阀进样，TDX-01填充色谱柱分离，热导检测器检测。

On the structure of the controller, embedded DSP acts as core processing unit to deal with data sampling, calculating, processing and outputting controlling current to control the action of braking pressure-servo-valve.

在控制器的结构实现上，采用了嵌入式DSP作为核心处理单元，实现数据的采集、计算和处理，并输出控制电流来控制刹车压力伺服阀动作。

The utility model is provided with separate isolating valve, aeration valve, vacuum valve and thief rod mating the sampling cavity to keep the air in the furnace cavity and realize on-line sampling.

本实用新型设置了独立的隔离、充气、真空阀门以及与取样腔配套的取样杆，使取样过程中的炉腔内气氛不变，达到在线取样的目的。

Because of its clog-proof function and tampers cleaning function, the clog-proof sampling valve has been widely used.

由于具有防堵和自清理堵塞物的功能，防堵取样阀的用途比较广泛。
