先导式减压 / 溢流阀
A cartridge-style pilot-operated
pressure reducing/ relieving valve
先导式减压／溢流阀
SYMBOL
压力 – 流量曲线 PRESSURE DROP VS.FLOW
说明 DESCRIPTION
In its steady state, the valve allows flow to pass from ② to ①，with the spring
chamber constantly drained at ③．On attainment of a pre-determined pressure at ① ,
the cartridge shifts to restrict input flow at ② , thereby regulating pressure at ① . In this
mode, the valve will also relieve ① to ③ over the reducing setting.
在①口的压力达到弹簧设定的压力时，从②到①减压。弹簧腔内排到③口。
当①口的压力超过预设定的压力时，②口渐渐关闭，①到③开始溢流。
