(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，浙江伺服液壓閥，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)泄式液控單向閥來說，浙江伺服液壓閥，當(dāng)反向油出口壓力超過一定值時(shí)，液控部分將失去控制作用，浙江伺服液壓閥，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(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。液壓閥用于降低并穩(wěn)定系統(tǒng)中某一支路的油液壓力。浙江伺服液壓閥</p><div

style="text-indent:25px">液壓裝置中容易產(chǎn)生噪聲的元件一般認(rèn)為是泵和閥，閥中又以溢流閥和電磁換向閥等為主。產(chǎn)生噪聲的因素很多。溢流閥的噪聲有流速聲和機(jī)械聲二種。流速聲中主要由油液振動(dòng)、空穴以及液壓沖擊等原因產(chǎn)生的噪聲。機(jī)械聲中主要由閥中零件的撞擊和磨擦等原因產(chǎn)生的噪聲。先導(dǎo)型溢流閥的導(dǎo)閥部分是一個(gè)易振部位。在高壓情況下溢流時(shí)，導(dǎo)閥的軸向開口很小，*0.003～0.006厘米。過流面積很小，流速很高，可達(dá)200米/秒，易引起壓力分布不均勻，使錐閥徑向力不平衡而產(chǎn)生振動(dòng)。另外錐閥和錐閥座加工時(shí)產(chǎn)生的橢圓度、導(dǎo)閥口的臟物粘住及調(diào)壓彈簧變形等，也會(huì)引起錐閥的振動(dòng)。所以一般認(rèn)為導(dǎo)閥是發(fā)生噪聲的振源部位。</p><p style="text-indent:25px">區(qū)分：節(jié)流閥、流量閥、調(diào)速閥 1）由于節(jié)流閥、調(diào)速閥在液壓系統(tǒng)中的主要功能是調(diào)節(jié)系統(tǒng)或所在支路的流量，所以統(tǒng)稱流量閥。 2）有時(shí)流量閥實(shí)際上是指調(diào)速閥。 3）從壓力流量基本公式看，節(jié)流閥只是改變閥口過流面積的大小，所控制的流量還要受其前后壓差變化的影響；調(diào)速閥（有時(shí)直接稱流量閥）采取或者串聯(lián)定差減壓閥，或者并聯(lián)定差溢流閥，分別構(gòu)成二通調(diào)速閥（可串聯(lián)配置在前、后，或并聯(lián)于執(zhí)行器前）和三通調(diào)速閥（只能串聯(lián)于執(zhí)行器前，而且只能控制一個(gè)負(fù)載）；液壓閥按用途分為溢流閥﹑減壓閥和順序閥。</p><div
