downstream pressure meaning in Chinese
活门后压力
下游压力
Examples
- To avoid this discharge , install a spring - loaded check valve ahead of the backflow assembly to " lock - in " the downstream pressure
如果放置在坑内，则应该采取措施使得排放总是在地面上，或对于坑内排放，要确保在安全阀下方配置一个适当的气隙。 - Series installations are recommended where very high supply pressure must be reduced to a very low downstream pressure . reducing the pressure in stages eliminates whistling and noise
如果很高的供应压力必须降低到很低的下游压力，则建议采用串联安装方式。逐步减低的压力避免出现啸声和噪音。 - The most common method of determining maximum differential pressure across the valve seats is to assign the maximum design or operating pressure the upstream value p1 and assume a downstream pressure p2 of 0 psig
测定阀门阀座的最大压差的最常用方法是将最大设计或工作压力作为上游的压力值p1 ，然后假定下游压力值p2为0psig - The gips / gdps series of automatic shut - off valves are safety devices designed to stop the flow of gas when the downstream pressure of the valve reaches a value larger than and / or smaller than the preset operating limit
升压感应关断型?与gdps ?降压感应关断型?系列自动关断阀为安全设备，设计当此阀下游压力达到大于或?和?小于预定操作限度的压力值时，来中断瓦斯流动。 - It was founded that the flux increases as the feed temperature , concentration and flow rate increase , and increases as the downstream pressure decreases . the separation factor increases as the feed flow rate and downstream pressure increase , and decreases as the feed temperature increases
由试验结果表明，温度升高，增大料液浓度，降低冷侧压力，以及增加料液流速，膜蒸馏通量增大；同时流速提高，温度降低，以及增大冷侧压力，分离因子增大。
