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。由于有弹性元件(弹簧)和运动质量(锥阀)的存在,构成了一个产生振荡的条件,而导阀前腔又起了一个共振腔的作用,所以锥阀发生振动后易引起整个阀的共振而发出噪声,发生噪声时一般多伴随有剧烈的压力跳动。先导式溢流阀发出的机械噪声,一般来自零件的撞击和由于加工误差等产生的零件磨擦。在先导型溢流阀发出的噪声中,有时会有机械性的高频振动声,一般称它为自激振动声。
