廣東專業(yè)的REXROTH溢流閥供貨商
力士樂先導(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，僅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。
由于有彈性元件（彈簧）和運(yùn)動(dòng)質(zhì)量（錐閥）的存在，構(gòu)成了一個(gè)產(chǎn)生振蕩的條件，而導(dǎo)閥前腔又起了一個(gè)共振腔的作用，所以錐閥發(fā)生振動(dòng)后易引起整個(gè)閥的共振而發(fā)出噪聲，發(fā)生噪聲時(shí)一般多伴隨有劇烈的壓力跳動(dòng)。
力士樂溢流閥是一種液壓壓力控制閥。在液壓設(shè)備中主要起定壓溢流作用，穩(wěn)壓，系統(tǒng)卸荷和安全保護(hù)作用。力士樂ZDBK/Z2DBK先導(dǎo)式溢流閥的特點(diǎn)：ZDBK/Z2DBK系列是疊加式閥門
