It is different with the manual exhaust Slurry pumps valve is not required to run the wind man, it must be installed on the location of gas pipeline set point, the so-called water gas gathering point is the top horizontal tube of the highest point, this horizontal pipe 3 ‰ gradient requirements, does not allow for local conditions such as depression and bending, when the air into the valve, the valve automatically opens, the air removed, the water level rose, it will automatically close the valve, hot water can not spill, from a virtually eliminating Manual exhaust is not timely, easy to form a "vapor lock" effect caused by hot water heating effects and huge loss of the state.

它与手动排气闸阀不同点是不需要人为跑风，它安装的位置一定要在管路集气点上，所谓集气点就是顶层供水横管的最高点处，对此横管有3‰倾斜度要求，不允许出现局部凹陷和弯曲等情况，当空气进入阀体后，阀门会自动开启，调节阀空气排除后水位上升，它会自动关阀，热水不能外溢，从根本上消除了手动排气不及时，易形成"气阻"影响供热效果和造成热水大量流失的弊端。
