1）由于節(jié)流閥、調(diào)速閥在液壓系統(tǒng)中的主要功能是調(diào)節(jié)系統(tǒng)或所在支路的流量，所以統(tǒng)稱流量閥。 2）有時(shí)流量閥實(shí)際上是指調(diào)速閥。 3）從壓力流量基本公式看，節(jié)流閥只是改變閥口過流面積的大小，所控制的流量還要受其前后壓差變化的影響；調(diào)速閥（有時(shí)直接稱流量閥）采取或者串聯(lián)定差減壓閥，或者并聯(lián)定差溢流閥，分別構(gòu)成二通調(diào)速閥（可串聯(lián)配置在前、后，或并聯(lián)于執(zhí)行器前）和三通調(diào)速閥（只能串聯(lián)于執(zhí)行器前，而且只能控制一個(gè)負(fù)載）；</p><p style="text-indent:25px">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。節(jié)流閥體沉積物的來源較為復(fù)雜，但可歸納為以下幾類： 1.油液中的機(jī)械雜質(zhì)或因氧化析出的膠質(zhì)、瀝青、碳渣等污物堆積在節(jié)流縫隙處。 2.由于油液老化或受到擠壓后產(chǎn)生帶電的極化分子，而節(jié)流縫隙的金屬表面上存在電位差，故極化分子被吸附到縫隙表面，形成牢固的邊界吸附層，吸附層厚度一般為5~8微米，因而影響了節(jié)流縫隙的大小。以上堆積、吸附物增長到一定厚度時(shí)，會(huì)被液流沖刷掉，隨后又重新附在閥口上。這樣周而復(fù)始，就形成了流量的脈動(dòng)。 3.閥口壓差較大時(shí)，因閥口溫度高，液體受擠壓的程度增強(qiáng)，金屬表面也更易受摩擦作用而形成電位差，因此壓差大時(shí)容易產(chǎn)生堵塞現(xiàn)象。壓力閥，主要是用來滿足對執(zhí)行機(jī)構(gòu)提出的力或力矩的要求。</p><div style="width:100%;text-align: center;"><img

style="text-indent:25px">流量閥:二通調(diào)速閥一般用于定壓系統(tǒng)，由于實(shí)現(xiàn)了負(fù)載壓力補(bǔ)償，在負(fù)載壓力作較大變化時(shí)，控制流量基本不受影響；但它將補(bǔ)償多余壓力以閥口壓力損失的形式消耗。系統(tǒng)多余流量也是以油液發(fā)熱形式消耗。三通調(diào)速閥由于具有負(fù)載適應(yīng)功能，即泵的出口壓力**比負(fù)載高一個(gè)定值（3－8bar），是一種節(jié)能系統(tǒng)。常自配先導(dǎo)壓力閥，不用另設(shè)安全閥，就可實(shí)現(xiàn)系統(tǒng)安全保護(hù)。在塑機(jī)行業(yè)，常常在三通閥基礎(chǔ)上，配置電液比例壓力先導(dǎo)閥與流量閥的比例調(diào)節(jié)機(jī)構(gòu)，構(gòu)成電液比例壓力流量復(fù)合控制閥，俗稱pq閥，既簡化結(jié)構(gòu)又節(jié)能。液壓閥用于降低并穩(wěn)定系統(tǒng)中某一支路的油液壓力。磚機(jī)溢流閥服務(wù)廠家</p><p
