style="text-indent:25px">對(duì)于液壓閥而言，其各個(gè)零件之間雖然大多由螺栓進(jìn)行連接，但是液壓閥在進(jìn)行設(shè)計(jì)時(shí)是非拆卸的，若缺乏專門用設(shè)備或者缺乏專業(yè)技術(shù)而強(qiáng)行進(jìn)行拆卸，其所可能導(dǎo)致的結(jié)果就是損壞液壓閥。所以，在拆卸之前維修人員應(yīng)當(dāng)將液壓閥結(jié)構(gòu)掌握，并且應(yīng)當(dāng)掌握各個(gè)零件之間連接方式，在拆卸過程中應(yīng)當(dāng)對(duì)不同零件之間位置關(guān)系進(jìn)行記錄。對(duì)閥體及閥芯等零件進(jìn)行檢查，觀察其污垢沉積情況，在對(duì)工作表面不造成損傷的基礎(chǔ)上，利用毛刷、棉紗以及非金屬刮板將集中污垢掃除。</p><p style="text-indent:25px">液壓閥中壓力波是一個(gè)小的沖擊波，本身產(chǎn)生的噪聲很小，但隨油液傳到系統(tǒng)中，如果同任何一個(gè)機(jī)械零件發(fā)生共振，就可能加大振動(dòng)和增強(qiáng)噪聲。所以在發(fā)生液壓沖擊噪聲時(shí)，一般多伴有系統(tǒng)振動(dòng)。先導(dǎo)式溢流閥發(fā)出的機(jī)械噪聲，一般來(lái)自零件的撞擊和由于加工誤差等產(chǎn)生的零件磨擦。在先導(dǎo)型溢流閥發(fā)出的噪聲中，有時(shí)會(huì)有機(jī)械性的高頻振動(dòng)聲，一般稱它為自激振動(dòng)聲。這是主閥和導(dǎo)閥因高頻振動(dòng)而發(fā)生的聲音。它的發(fā)生率與回油管道的配置、流量、壓力、油溫（粘度）等因素有關(guān)。一般情況下，管道口徑小、流量少、壓力高、油液粘度低，自激振動(dòng)發(fā)生率就高。液壓閥的通道中有油液，很容易就會(huì)發(fā)生油液的沉淀。</p><div

：各種的規(guī)格型號(hào)，可以系統(tǒng)的較高壓力和通過閥的實(shí)際流量(從工況圖和系統(tǒng)圖查得)為依據(jù)并考慮閥的控制特性、穩(wěn)定性及油口尺寸、外形尺寸、安裝連接方式、操縱方式等，從產(chǎn)品樣本或型錄中選取。金澤液壓生產(chǎn)的液壓系統(tǒng)中配套各類液壓控制閥選擇注意事項(xiàng)如下：液壓閥的實(shí)際流量。液壓的實(shí)際流量與油路的串、并聯(lián)有關(guān)：串聯(lián)油路各處流量相等；同時(shí)工作的并聯(lián)油路的流量等于各條油路流量之和。此外，對(duì)于采用單活塞桿液壓缸的系統(tǒng)，要注意活塞外伸和內(nèi)縮時(shí)的回油流量的不同：內(nèi)縮時(shí)無(wú)桿腔回油與外伸時(shí)有桿腔回油的流量之比，與兩腔面積之比相等。液壓閥按功能分類：（溢流閥，減壓閥，順序閥，卸荷閥）。鎮(zhèn)江液壓閥廠</p><p style="text-indent:25px">液壓閥和原動(dòng)機(jī)輸出軸間應(yīng)采用彈性聯(lián)軸器連接，嚴(yán)禁在液壓泵軸上安裝帶輪或齒輪驅(qū)動(dòng)液壓泵。鎮(zhèn)江液壓閥廠</p><p style="text-indent:25px">當(dāng)溢流閥起溢流穩(wěn)壓作用時(shí)稱溢流閥，起限壓保護(hù)作用時(shí)稱安全閥。那么要怎么區(qū)分呢？在定量泵調(diào)速系統(tǒng)中，由于泵的供油流量是一定的，當(dāng)通過節(jié)流閥進(jìn)行流量調(diào)節(jié)（節(jié)流調(diào)速過程）時(shí)，多余的流量則從溢流閥溢流回油箱，這時(shí)溢流閥一方面起調(diào)定系統(tǒng)壓力的作用，另一方面在節(jié)流閥進(jìn)行流量調(diào)節(jié)時(shí)起溢流穩(wěn)壓作用，溢流閥在這類工作過程中是開啟的（常開）。而在變量泵系統(tǒng)中，速度的調(diào)節(jié)是通過改變泵的流量來(lái)實(shí)現(xiàn)的，這個(gè)過程中，沒有多余的流量從溢流閥溢出，溢流閥不開啟（常閉）。只有當(dāng)負(fù)載壓力達(dá)到或超過溢流閥的調(diào)定壓力時(shí)，溢流閥才開啟、溢流，使系統(tǒng)壓力不再升高，起限定系統(tǒng)較高壓力，保護(hù)液壓系統(tǒng)的作用，像這種情況下溢流閥我們稱作為安全閥。鎮(zhèn)江液壓閥廠</p></p><br
