针对高压降下的节流减压易产生气蚀导致减压阀节流件过早损坏问题,设计了平衡套筒式阀瓣结构,使一套阀瓣实现两级节流,减小单级节流压降,避免了气蚀产生。
Aimed at the problem of premature failure caused by the throttling of the relief valve caused by the cavitation erosion caused by the high pressure drop, a balanced sleeve valve disc structure was designed to achieve a two-stage throttling and a single-stage throttling Flow pressure drop, to avoid cavitation.
