进口倒吊桶式疏水阀 Inverted bucket steam trap
倒吊桶式疏水阀内部是一个倒吊桶为液位敏感件，吊桶开口向下。
The interior of the inverted bucket steam trap is BS inverted bucket, a liquid level sensitive part, with the bucket's opening downward.

倒吊桶式蒸汽疏水阀的开启和关闭是根据凝结水和蒸汽的密度差来动作的，其动作准确，可靠。
Inverted bucket steam trap opening and closing action is based on the difference in density of the condensate and steam to its accurate and reliable.
倒吊桶式疏水阀内部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，抗污性能好。过冷度小，漏汽率小于3%，最大背压率为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。
