The experiment and calculating example show when concentration of polymer solution increases angle of lag of valve ball opening increases and pump admission coefficient drops.
试验和计算实例表明,随着聚合物浓度的增加,阀球开启滞后角度增大,泵充满系数降低。
When the water level of condensate in the drain sump drops, the cup to shut the admission pipe falls down, the passage for steam to enter into the valve body is opened.
由于通往阀腔的进汽管被密封,凝结水从集水仓流经进水管进入阀腔,倒吊桶下沉,打开排水阀嘴,周期性的开始排水。
