一种集水锤消除器、逆止阀、存水排放井、闸阀四种功能于一体的新型管道全能自动保护器最近在内蒙古自治区宁城县水利局研制成功并获专利。 该保护器安装在水泵出口处,另一端与管道连接。当泵向管道正向输水时,管道阀自动打开,解压阀自动关闭;当因事故停泵时,管道阀自动关闭,使逆向水流不冲击水泵,解压阀自动打开,使逆向水流沿解压阀管道排向水源(井),使管道不受水锤冲击,从而达到保护水泵的目的。该保护器靠法兰连接,安装简便,可在北方喷灌、引水、管灌工程等领域广泛应用。
A new type of automatic water pipeline protector with water hammer eliminator, check valve, water discharge well and gate valve has been recently successfully developed and patented in Ningcheng County Water Conservancy Bureau of Inner Mongolia Autonomous Region. The protector is installed at the outlet of the pump and connected to the pipe at the other end. When the pump to the pipeline forward water, the pipeline valve automatically opens, decompression valve automatically shut down; when the pump is stopped due to an accident, the pipeline valve automatically shut down so that the reverse flow does not impact the pump, decompression valve automatically opens, so that the reverse flow along the decompression valve Pipes to the water (well), so that the water hammer from the pipeline impact, so as to achieve the purpose of protecting the pump. The protector by flange connection, easy to install, can be widely used in the northern sprinkler irrigation, water diversion, pipe irrigation and other fields.
