style="text-indent:25px">液控單向閥在使用維修過程中容易出現(xiàn)問題，因此要注意這些事項(xiàng)：(1)必須保證液控單向閥有足夠的控制壓力，一定不允許控制壓力失壓。應(yīng)注意控制壓力是否滿足反向開啟的要求。如果液控單向閥的控制引自主系統(tǒng)時，則要分析主系統(tǒng)壓力的變化對控制油路壓力的影響，以免出現(xiàn)液控單向閥的誤動作。(2)根據(jù)液控單向閥在液壓系統(tǒng)中的位置或反向出油腔后的液流阻力（背壓）大小，合理選擇液控單向閥的結(jié)構(gòu)（簡式或復(fù)式）及泄油方式（內(nèi)泄或外泄）。對于內(nèi)泄式液控單向閥來說，當(dāng)反向油出口壓力超過一定值時，液控部分將失去控制作用，故內(nèi)泄式液控單向閥一般用于反向出油腔無背壓或背壓較小的場合；而外泄式液控單向閥可用于反向出油腔背壓較高的場合，以降低較小的控制壓力，節(jié)省控制功率。系統(tǒng)若采用內(nèi)卸式，則柱塞缸將斷續(xù)下降發(fā)出振動和噪聲。仙居木工機(jī)械調(diào)壓閥MRV-03W液壓閥拆卸時記錄各零件間的位置關(guān)系。</p><div

：各種的規(guī)格型號，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；同時工作的并聯(lián)油路的流量等于各條油路流量之和。此外，對于采用單活塞桿液壓缸的系統(tǒng)，要注意活塞外伸和內(nèi)縮時的回油流量的不同：內(nèi)縮時無桿腔回油與外伸時有桿腔回油的流量之比，與兩腔面積之比相等。</p><p style="text-indent:25px">液壓閥自吸高度不超過500mm (或進(jìn)口真空度不超過0.03MPa)，若采用補(bǔ)油泵供油，供油壓力不得超過0.5MPa，當(dāng)供油壓力超過0.5MPa時，要改用耐壓密封圈。對于柱塞泵，應(yīng)盡量采用倒灌自吸方式。比例控制閥的結(jié)構(gòu)相對簡單，價格也較為便宜，可稱之為廉價的電液伺服元件。介于電液開關(guān)控制和電液伺服控制之間的比例控制閥，可謂是將上述兩種元件的特點(diǎn)加以結(jié)合，實(shí)際作用也介于其中，如注塑機(jī)、型材擠壓機(jī)這類設(shè)備，它在這些簡易自動化、簡易數(shù)控以及單參數(shù)適應(yīng)控制的液壓系統(tǒng)方面堪稱首要選擇。但這類閥也有一定劣勢，相比伺服閥，它的頻率響應(yīng)較低，存在一定的死區(qū)和滯環(huán)，對控制精度要求較高和響應(yīng)要素較快的閉環(huán)控制系統(tǒng)而言，其能力也稍顯不足，不過針對速度（單參數(shù)）閉環(huán)控制系統(tǒng)和一般開環(huán)電液控制系統(tǒng)，它基本可滿足響應(yīng)需求。實(shí)際應(yīng)用方面，液壓閥受配合閥壓力油的控制，通?？膳c電磁配壓閥組合使用。</p><div

style="text-indent:25px">關(guān)于液壓閥的設(shè)計(jì)首先從液壓閥的設(shè)計(jì)尺寸來討論。液壓閥組的長寬高尺寸一般參照組成液壓閥組的零件的大小來確定，例如，液壓閥組的高度，在不影響實(shí)際作用的前提下，盡量跟元件的高度保持一致。液壓閥組的長度，在不影響布局和結(jié)構(gòu)的前提下，由螺釘孔的孔徑或者長度的尺寸來決定。液壓閥組的寬度跟長度的決定因素大致一樣。其次，我們介紹標(biāo)注尺寸，這一步主要是在設(shè)計(jì)繪圖時應(yīng)用，要標(biāo)注一些元件的端口，孔徑，每組尺寸，大小等等。然后是通道的設(shè)計(jì)，在這個設(shè)計(jì)當(dāng)中較重要的是布局，對這個系統(tǒng)進(jìn)行的整體的安排，把油路分類，首先一定要使得主要油路導(dǎo)通，然后，對于小的油路或者其他油路再逐漸導(dǎo)通。這些液壓閥的通道，在設(shè)計(jì)的時候一定要保證長度合適，轉(zhuǎn)角比較少，油道的孔合適，這樣才能有效的控制液壓閥組的重量、大小以及體積，才能合理的利用。液壓閥進(jìn)、出油口應(yīng)安裝牢固，密封裝置要可靠。仙居木工機(jī)械調(diào)壓閥MRV-03W</p><p style="text-indent:25px">流量閥的作用是在閥的進(jìn)出口壓差變化的情況下，維持通過的流量恒定。仙居木工機(jī)械調(diào)壓閥MRV-03W</p><p style="text-indent:25px">液壓閥連接注意事項(xiàng)：① 液壓閥可以用支座或法蘭安裝，泵和原動機(jī)應(yīng)采用共同的基礎(chǔ)支座，法蘭和基礎(chǔ)都應(yīng)有足夠的剛性。特別注意:流量大于 (或等于)160L/min的柱塞泵，不宜安裝在油箱上。② 液壓閥和原動機(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)動液壓泵，若一定要用帶輪或齒輪與泵連接，則應(yīng)加一對支座來安裝帶輪或齒輪，該支座與泵軸的同軸度誤差應(yīng)不大于Φ0.05mm。 ③ 吸油管要盡量短、直、大、厚，吸油管路一般需設(shè)置公稱流量不小于泵流量2倍的粗過濾器 (過濾精度一般為80～180μm)。液壓泵的泄油管應(yīng)直接接油箱，回油背壓應(yīng)不大于0.05MPa。油泵的吸油管口、回油管口均需在油箱較低油面200mm以下。特別注意在柱塞泵吸油管道上不允許安裝濾油器，吸油管道上的截止閥通徑應(yīng)比吸油管道通徑大一擋，吸油管道長L<2500mm，管道彎頭不多于兩個。仙居木工機(jī)械調(diào)壓閥MRV-03W</p></p><br
