英国NORGREN诺冠比例阀在是一个倒吊桶为液位敏感件，吊桶开口向下，倒吊桶连接杠杆带动阀心开闭阀门。倒吊桶式疏水阀能排空气，不怕水击，抗污好。过冷度小，漏汽率小于3%，zui大背压率为75%，连接件比较多，灵敏度不如自由浮球式疏水阀。因倒吊桶式疏水阀是靠蒸汽向上浮力关闭阀门，工作压差小于0.1MPA时，不适合选用。当装置刚启动时，管道内的空气和低温凝结水进入疏水阀内，倒吊桶靠自身重量下坠，倒吊桶连接杠杆带动阀心开启阀门，空气和低温凝结水迅速排出。当蒸汽进入倒吊桶内，倒吊桶的蒸汽产生向上浮力，倒吊桶上升连接杠杆带动阀心关闭阀门。倒吊桶上开有一小孔，当一部份蒸汽从小孔排出，另一部份蒸汽产生凝结水，倒吊桶失去浮力，靠自身重量向下沉，倒吊桶连接杠杆带动阀心开启阀门，循环工作，间断排水。
