2.功用及性能要求：減壓閥用來(lái)降低系統(tǒng)中某一回路的壓力。使其出口壓力降低且恒定的減壓閥稱為定值輸出減壓閥；使其出口壓力與某一負(fù)載壓力之差恒定的減壓閥稱為定差減壓閥；使其入口壓力與出口壓力比值一定的減壓閥稱為定比減壓閥。對(duì)定值輸出減壓閥的要求是：不管入口壓力如何變化，出口壓力應(yīng)能維持恒定，且不受通過(guò)閥的流量變化的影響。對(duì)定差或定比減壓閥來(lái)說(shuō)，則要求不管入口壓力或出口壓力如何變化，應(yīng)使壓差恒定或它們的比值恒定。液壓閥可用于遠(yuǎn)距離控制水電站油、氣、水管路系統(tǒng)的通斷。</p><div
