upstream vessel的意思|示意

The configuration of the reaction vessel permits flow of metal during LARS tilting either upstream and back into the furnace or downstream to the casting system.

反应容器的形状能够让金属无论是在逆流回到熔炉时还是顺流到熔铸系统的时候，都随着LARS的掀动而流动。

The inlet pipe penetration into the vessel, the pressure drop across any block valves used. upstream of the venting device, and the inlet piping must be considered when determining these losses.

对与容器连通的进口管，要使用其通过阻断阀时的压力降。在确定这些压损时，必须要考虑进口管线和放空装置的上游线路。
