英國NORGREN諾冠比例閥在是一個倒吊桶為液位敏感件，吊桶開口向下，倒吊桶連接杠桿帶動閥心開閉閥門。倒吊桶式疏水閥能排空氣，不怕水擊，抗污好。過冷度小，漏汽率小于3%，zui大背壓率為75%，連接件比較多，靈敏度不如自由浮球式疏水閥。因倒吊桶式疏水閥是靠蒸汽向上浮力關閉閥門，工作壓差小于0.1MPA時，不適合選用。當裝置剛啟動時，管道內的空氣和低溫凝結水進入疏水閥內，倒吊桶靠自身重量下墜，倒吊桶連接杠桿帶動閥心開啟閥門，空氣和低溫凝結水迅速排出。當蒸汽進入倒吊桶內，倒吊桶的蒸汽產生向上浮力，倒吊桶上升連接杠桿帶動閥心關閉閥門。倒吊桶上開有一小孔，當一部份蒸汽從小孔排出，另一部份蒸汽產生凝結水，倒吊桶失去浮力，靠自身重量向下沉，倒吊桶連接杠桿帶動閥心開啟閥門，循環(huán)工作，間斷排水。
