節(jié)流閥是通過改變節(jié)流截面或節(jié)流長(zhǎng)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(jiǎn)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(chǎng)合
節(jié)流閥的性能要求是：
·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，外泄漏量也要小；
·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。
