style="text-indent:25px">節(jié)流閥應(yīng)安裝在易于方便操作的位置上。節(jié)流閥安裝時(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="text-indent:25px">液壓閥是一種用壓力油操作的自動(dòng)化元件，它受配壓閥壓力油的控制，通常與電磁配壓閥組合使用，可用于遠(yuǎn)距離控制水電站油、氣、水管路系統(tǒng)的通斷。常用于夾緊、控制、潤滑等油路。有直動(dòng)型與先導(dǎo)型之分，多用先導(dǎo)型。液壓傳動(dòng)中用來控制液體壓力﹑流量和方向的元件。其中控制壓力的稱為壓力控制閥，控制流量的稱為流量控制閥，控制通﹑斷和流向的稱為方向控制閥。按控制方法分類：手動(dòng)，電控，液控。按功能分類：流量閥（節(jié)流閥、調(diào)速閥，分流集流閥）、壓力閥（溢流閥，減壓閥，順序閥，卸荷閥）、方向閥（電磁換向閥、手動(dòng)換向閥、單向閥、液控單向閥）。按安裝方式分：板式閥，管式閥，疊加閥，螺紋插裝閥，蓋板閥。按操縱方式分：手動(dòng)閥，機(jī)動(dòng)閥，電動(dòng)閥，液動(dòng)閥，電液動(dòng)閥等。液壓閥應(yīng)避免長期使用，否則將影響液壓泵的壽命。蘇州汽車液壓閥</p><p
