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(lái)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(zhǎng)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，橡膠機(jī)充液閥訂購(gòu)，橡膠機(jī)充液閥訂購(gòu)，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，橡膠機(jī)充液閥訂購(gòu)，因此壓差大時(shí)容易產(chǎn)生堵塞現(xiàn)象。液壓閥要求：所控制的參量（壓力或流量）穩(wěn)定，受外部干擾時(shí)變化量小。橡膠機(jī)充液閥訂購(gòu)</p><div
