溢流阀是一种液压压力控制阀,在液压设备中主要起定压溢流,稳压,系统卸荷和安全保护作用。
溢流阀在装配或使用中,由于O形密封圈、组合密封圈的损坏,或者安装螺钉、管接头的松动,都可能造成不应有的外泄漏。

液压装置中容易产生噪声的元件一般认为是泵和阀,阀中又以溢流阀和电磁换向阀等为主。
产生噪声的因素很多。
溢流阀的噪声有流速声和机械声二种。
流速声中主要由油液振动、空穴以及液压冲击等原因产生的噪声。
机械声中主要由阀中零件的撞击和磨擦等原因产生的噪声。

先导型溢流阀的导阀部分是一个易振部位如图3所示。
在高压情况下溢流时,导阀的轴向开口很小,仅0.003~0.006厘米。
过流面积很小,流速很高,可达200米/秒,易引起压力分布不均匀,使锥阀径向力不平衡而产生振动。
另外锥阀和锥阀座加工时产生的椭圆度、导阀口的脏物粘住及调压弹簧变形等,也会引起锥阀的振动。
所以一般认为导阀是发生噪声的振源部位。
