CARX compound exhaust valve

Product Type : Exhaust valve
Introduction : This series of composite exhaust valve is suitable for installation in the pump outlet or water distribution pipeline. It is used to eliminate a large amount of air gathered in the pipeline, or the trace air gathered at the higher part of the pipeline is discharged into the atmosphere to improve the use efficiency of the pipeline and the water pump, and once the negative pressure is generated in the pipe, the valve quickly sucks in the outside air to protect the pipeline from damage caused by negative pressure.

操作原理

当管内开始注水时；塞头停留在开启位置，进行大量排气，当空气排完时，阀内积水，浮球被浮起，活塞至关闭位置，停止大量排气，当管内水正常输送时，如有少量空气聚集在阀内到相当程度，阀内水位下降，浮球随之下降，此时空气由小孔排出，或由自动排气阀小孔排出。当抽水机停止，管内水流空时或遇管内产生负压时，此时活塞迅速开启，吸入空气，确保管线安全。
