武漢賀德克節(jié)流閥RV-20-01.X/0 產(chǎn)品廣泛應(yīng)用于鋼鐵、冶金、石油化工、航天、船舶制造、煤炭、水泥、電力、汽車、工程機械、食品、林業(yè)、紡織、皮革、造紙等行業(yè)領(lǐng)域

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

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）并制成頂jian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。由于節(jié)流閥的流量不僅取決于節(jié)流口面積的大小，還與節(jié)流口前后的壓差有關(guān)，閥的剛度小，

故只適用于執(zhí)行元件負(fù)載變化很小且速度穩(wěn)定性要求不高的場合。
