style="text-indent:25px">液控單向閥在使用維修過(guò)程中容易出現(xiàn)問(wèn)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(shí)，則要分析主系統(tǒng)壓力的變化對(duì)控制油路壓力的影響，以免出現(xiàn)液控單向閥的誤動(dòng)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(jiǎn)式或復(fù)式）及泄油方式（內(nèi)泄或外泄）。對(duì)于內(nèi)泄式液控單向閥來(lái)說(shuō)，當(dāng)反向油出口壓力超過(guò)一定值時(shí)，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(wú)背壓或背壓較小的場(chǎng)合；而外泄式液控單向閥可用于反向出油腔背壓較高的場(chǎng)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(dòng)和噪聲。</p><p style="text-indent:25px">液壓閥中若閥體與閥門兩者之間配合間隙與產(chǎn)品圖紙中所規(guī)定間隙相比較而言有所增大，且增大程度在20%~25%之間，此時(shí)應(yīng)當(dāng)采取一定方法使閥芯尺寸增加，之后再進(jìn)行研配修復(fù)。簡(jiǎn)稱液壓閥在液壓系統(tǒng)中的功用是通過(guò)控制調(diào)節(jié)液壓系統(tǒng)中油液的流向、壓力和流量，使執(zhí)行器及其驅(qū)動(dòng)的工作機(jī)構(gòu)獲得所需的運(yùn)動(dòng)方向、推力（轉(zhuǎn)矩）及運(yùn)動(dòng)速度（轉(zhuǎn)速）等。任何一個(gè)液壓系統(tǒng)，不論其如何簡(jiǎn)單，都不能缺少液壓閥；同一工藝目的的液壓機(jī)械設(shè)備，通過(guò)液壓閥的不同組合使用，可以組成油路結(jié)構(gòu)截然不同的多種液壓系統(tǒng)方案。因此，液壓閥是液壓技術(shù)中品種與規(guī)格較多、應(yīng)用較普遍、較活躍的部分（元件）；一個(gè)新設(shè)計(jì)或正在運(yùn)轉(zhuǎn)的液壓系統(tǒng)，能否按照既定要求正常可靠地運(yùn)行，在很大程度上取決于其中所采用的各種液壓閥的性能優(yōu)劣及參數(shù)匹配是否合理。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

style="text-indent:25px">液控單向閥是可以使單向閥反向流通的閥。這種閥在煤機(jī)械的液壓支護(hù)設(shè)備中占有較重要的地位。液控單向閥與普通單向閥不同之處是多了一個(gè)控制油路K，當(dāng)控制油路未接通壓力油液時(shí)，液控單向閥就象普通單向閥一樣工作，壓力油只從進(jìn)油口流向出油口，不能反向流動(dòng)。當(dāng)控制油路油控制壓力輸入時(shí)，活塞頂桿在壓力油作用下向右移動(dòng)，用頂桿頂開單向閥，使進(jìn)出油口接通。若出油口大于進(jìn)油口就能使油液反向流動(dòng)。液控單向閥是方向控制閥中的一種。具體分類：方向控制閥按其在液壓系統(tǒng)中的功能分為單向閥和換向閥兩大類。單向閥在液壓傳動(dòng)中有普通單向閥和液控單向閥。液壓閥的選擇要注意方向控制的選用。寧波液壓閥蓋板</p><p style="text-indent:25px">將液壓閥拆卸清洗，這樣才能及時(shí)的使得液壓閥的功能得到恢復(fù)。調(diào)壓閥DT-01預(yù)定</p><p style="text-indent:25px">液壓閥按用途分為單向閥和換向閥。單向閥：只允許流體在管道中單向接通，反向即切斷。換向閥：改變不同管路間的通、斷關(guān)系。根據(jù)閥芯在閥體中的工作位置數(shù)分兩位、三位等；根據(jù)所控制的通道數(shù)分兩通、三通、四通、五通等；根據(jù)閥芯驅(qū)動(dòng)方式分手動(dòng)，機(jī)動(dòng)，電動(dòng)，液動(dòng)等。60年代后期，在上述幾種液壓控制閥的基礎(chǔ)上又研制出電液比例控制閥。它的輸出量（壓力、流量）能隨輸入的電信號(hào)連續(xù)變化。電液比例控制閥按作用不同，相應(yīng)地分為電液比例壓力控制閥﹑電液比例流量控制閥和電液比例方向控制閥等。調(diào)壓閥DT-01預(yù)定</p></p><br
