ADRL-20/8 ATOS溢流閥- ARE-06/350 阿托斯節(jié)流閥是通過改變節(jié)流截面或節(jié)流長度以控制流體流量的閥門。將節(jié)流閥和單向閥并聯(lián)則可組合成單向節(jié)流閥。節(jié)流閥和單向節(jié)流閥是簡易的流量控制閥，在定量泵液壓系統(tǒng)中，節(jié)流閥和溢流閥配合，可組成三種節(jié)流調(diào)速系統(tǒng)，即進(jìn)油路節(jié)流調(diào)速系統(tǒng)、回油路節(jié)流調(diào)速系統(tǒng)和旁路節(jié)流調(diào)速系統(tǒng)。節(jié)流閥沒有流量負(fù)反饋功能，不能補(bǔ)償由負(fù)載變化所造成的速度不穩(wěn)定，一般僅用于負(fù)載變化不大或?qū)λ俣确€(wěn)定性要求不高的場合。

對節(jié)流閥的性能要求是：  節(jié)流閥
·流量調(diào)節(jié)范圍大，流量一壓差變化平滑； 　　
·內(nèi)泄漏量小，若有外泄漏油口，外泄漏量也要?。?　　
·調(diào)節(jié)力矩小，動(dòng)作靈敏。 　　
節(jié)流閥（Choke valve）的外形結(jié)構(gòu)與截止閥并無區(qū)別，只是它們啟閉件的形狀有所不同。節(jié)流閥的啟閉件大多為圓錐流線型，通過它改變通道截面積而達(dá)到調(diào)節(jié)流量和壓力。節(jié)流閥供在壓力降極大的情況下作降低介質(zhì)壓力之用。介質(zhì)在節(jié)流閥瓣和閥座之間流速很大，以致使這些零件表面很快損壞－即所謂氣蝕現(xiàn)象。為了盡量減少氣蝕影響，閥瓣采用耐氣蝕材料（合金鋼制造）并制成*角為140～180的流線型圓錐體，這還能使閥瓣能有較大的開啟高度，一般不推薦在小縫隙下節(jié)流。 ADRL-20/8 ATOS溢流閥- ARE-06/350 阿托斯節(jié)流閥
