特征:
Excelon設(shè)計(jì)允許與其他Excelon產(chǎn)品一起管式或模塊式安裝
帶防護(hù)罩的按壓鎖定式調(diào)節(jié)旋鈕
保護(hù)壓縮空氣系統(tǒng)避免過壓
壓力不均勻引起的噪聲:
先導(dǎo)型溢流閥的導(dǎo)閥部分是一個(gè)易振部位如圖3所示。在高壓情況下溢流
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
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
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
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
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)。
