Z2FS6-2-44/2QV REXROTH節(jié)流閥
節(jié)流閥特點(diǎn)
1、構(gòu)造較簡(jiǎn)單，便于制造和維修，成本低。
2、調(diào)節(jié)精度不高，不能作調(diào)節(jié)使用。
3、密封面易沖蝕，不能作切斷介質(zhì)用。
4、密封性較差。
節(jié)流閥按通道方式可分為直通式和角式兩種；按啟閉件的形狀分，有針形、溝形和窗形三種。節(jié)流閥的安裝與維護(hù)應(yīng)注意以下事項(xiàng)：
該閥經(jīng)常需要操作，因此應(yīng)安裝在易于方面便操作的位置上。
安裝時(shí)要注意介質(zhì)方向與閥體所標(biāo)箭頭方向保持一致。
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(chǎng)合。
對(duì)于執(zhí)行元件負(fù)載變化大及對(duì)速度穩(wěn)定性要求高的節(jié)流調(diào)速系統(tǒng)，必須對(duì)節(jié)流閥進(jìn)行壓力補(bǔ)償來(lái)保持節(jié)流閥前后壓差不變，從而達(dá)到流量穩(wěn)定。

Z2FS6-2-44/2QV REXROTH節(jié)流閥
對(duì)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��；
·調(diào)節(jié)力矩小，動(dòng)作靈敏。
節(jié)流閥(throttle valve)的外形結(jié)構(gòu)與截止閥并無(wú)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(guò)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－即所謂汽蝕現(xiàn)象。為了盡量減少汽蝕影響，閥瓣采用耐汽蝕材料（合金鋼制造）并制成頂尖角為140～180的流線型圓錐體，這還能使閥瓣能有較大的開(kāi)啟高度，一般不推薦在小縫隙下節(jié)流。
