先導(dǎo)溢流閥的主閥上腔壓力，是由先導(dǎo)閥加于控制的。如果先導(dǎo)閥正常工作，即主閥上腔有先導(dǎo)閥規(guī)定的壓力，則整個溢流閥就會在系統(tǒng)壓力到達(dá)調(diào)定壓力時(shí)其主閥口打開一定的開度，一方面能將系統(tǒng)多余流量流回油箱，另一方面又能維持系統(tǒng)的壓力為先導(dǎo)閥的調(diào)定值?？梢?，先導(dǎo)閥主要管壓力，主閥服從先導(dǎo)閥的領(lǐng)導(dǎo)，在先導(dǎo)閥動作時(shí)將主閥口開到合適大小，正好將多余流量流出去，又不影響系統(tǒng)壓力。

淺析先導(dǎo)式溢流閥與直動型溢流閥的區(qū)別
溢流閥可分為直動型和先導(dǎo)式兩類。直動型溢流閥是作用在閥芯上的主油路液壓力與調(diào)壓彈簧力直接相平衡的溢流閥。根據(jù)閥口和測壓面結(jié)構(gòu)形式不同，形成三種基本結(jié)構(gòu)。
先導(dǎo)式溢流閥：主閥彈簧主要用于克服閥芯的摩擦力，彈簧剛度小。當(dāng)溢流量變化引起主閥彈簧壓縮量變化時(shí)，彈簧力變化較小，因此閥進(jìn)口壓力變化也較小。調(diào)壓精度高，廣泛應(yīng)用于高壓、大流量系統(tǒng)。
溢流閥的閥芯在移動過程中要受到摩擦力的作用，閥口開大和關(guān)小時(shí)的摩擦力方向剛好相反，使溢流閥開啟時(shí)的特性與關(guān)閉時(shí)的特性產(chǎn)生差異。
