自由半浮球式疏水阀：
自由半浮球式疏水阀只有一个半浮球式的球桶为活动部件，开口朝下，球桶即是启闭件，又是密封件。整个球面都可为密封，使用寿命很长，能抗水锤，没有易损件，无故障，经久耐用，无蒸汽泄漏。背压率大于80%，能排饱和温度凝结水，***小过冷度为0℃，加热设备里不存水，能使加热设备达到换热效率。
当装置刚启动时，管道内的空气和低温凝结水经过发射管进入疏水阀内，阀内的双金属片排空元件把球桶弹开，阀门开启，空气和低温凝结水迅速排出。当蒸汽进入球桶内，球桶产生向上浮力，同时阀内的温度升高，双金属片排空元件收缩，球捅漂向阀口，阀门关闭。当球桶内的蒸汽变成凝结水，球桶失去浮力往下沉，阀门开启，凝结水迅速排出。当蒸汽再进入球桶之内，阀门再关闭，间断和连续工作。
3.杆浮球式疏水阀：
杠杆浮球式疏水阀基本特点与自由浮球式相同，内部结构是浮球连接杠杆带动阀心，随凝结水的液位升降进行开关阀门。杠杆浮球式疏水阀利用双阀座增加凝结水排量，可达到体积小排量大，疏水量达100吨/小时，是大型加热设备***理想的疏水阀。4.倒吊桶式疏水阀：
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%，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。
