Filters should be installed with by - pass and block valves to permit by - passing the filter during element changes if the stream cannot be shut down to allow element changes 假如在更换滤芯时不能关闭液流,就应该在过滤器上安装旁通阀和断流阀,以便在更换滤芯期间使液流从旁路绕过过滤器。
Filters should be installed with by - pass and block valves to permit by - passing the filter during element changes if the stream cannot be shut down to allow element changes 如果支流不能被关闭而允许元素改变,则在元素改变过程中,应该在过滤器上安装旁通阀和截断阀,从而允许元素从旁路绕过过滤器。
It is also worth noting that this is exactly why we do not allow cell phones into dplng process plant areas that contain lng or natural gas e . g . the terminal process area and the pipeline off take & block valve stations 值得一提的是,这也正是为什么我们禁止将手机带入我们的液化天然气或天然气等的工艺厂区,接收站工艺区,管线分输站和阀室的原因。
