下面就这几种方式进行分析和比较：阀门节流改变离心泵流量*简单的方法就是调节泵出口阀门的开度，而水泵转速保持不变(一般为额定转速)，其实质是改变管路特性曲线的位置来改变泵的工况点。如图1所示，水泵特性曲线Q-H与管路特性曲线Q-h的交点A为阀门全开时水泵的极限工况点。关小阀门时，管道局部阻力增加，水泵工况点向左移至B点，相应流量减少。阀门全关时，相当于阻力无限大，流量为零，此时管路特性曲线与纵坐标重合。

4WE6D60/220V比例阀供应临沭五金常识之蒸汽疏水阀的工作原理：1.蒸汽疏水阀安装在蒸汽加热设备与凝结水回水集管之间。开车时，桶在底部，阀门全开。凝结水进入疏水阀后流到桶底，充满阀体，全部浸没桶体，然后，凝结水通过全开阀门排至回水集管。蒸汽也从桶体底部进入疏水阀，占据桶体内的顶部，产生浮力。桶体慢慢升起，逐渐向阀座方向移动杠杆，直到完全关闭阀门。空气和化碳气体通过桶体的排气小孔，聚集在疏水阀的顶部。从排气孔排出的蒸汽，都会因疏水阀的散热而凝结。
