The gas flow path of SP - 3420 gas chromatograph was modified by adding a 10-way switch valve for analyzing micro-amount CO and CO2 in polymer grade propylene.
为了分析聚合级丙烯中的CO和CO2，对SP-3420型气相色谱仪的气路系统作了改装，增加了一个十通阀。
Two, by the structural constraints of the structure to do the following Path DN200 valves, valve plates are the reasons for the overall structure of thick, large flow resistance.
受结构条件的限制该结构不适应做通径DN200以下阀门，原因是阀板整体结构太厚，流阻大。
CS: GO is being developed by Valve in cooperation with Seattle-based Hidden Path Entertainment.
CS：GO是正在开发中的合作与阀门位于西雅图的隐藏路径娱乐。
Second, the method determines the optimum valve gate location in each sub-moulding by applying equal-flow-path-length algorithm.
然后按照等流长算法求各分区的最佳阀浇口位置；
