Description

负压吸水供水设备
本实用新型涉及一种供水设备,特别是一种负压吸水供水设备。
目前的供水设备,只能采用将水泵安装在水箱底部,或水位侧面以直接吸水方式供水,这样就使得安装困难,运行不安全,不利管理。
本实用新型的目的是提供一种可将供水设备安装在水池、水箱等水源上面,安装方便、安全可靠、便于管理采用负压吸水的负压吸水供水设备。
本实用新型的技术方案是:包括水泵1,其特征在于:水泵1的入口12与负压罐2的出口11相接,负压罐2的入口10高于负压罐出口11,负压罐体设有高于出口11的带有封闭装置的注水孔9。
本实用新型与现有技术相比,具有可将供水设备安装在水池、水箱等水源上方,安全可靠便于管理以负压吸水达到供水目的的优点。
以下将结合附图对本实用新型作进一步的详细描述:
图1是负压吸水供水设备示意图;
图2是负压罐结构示意图。
如图1、2所示水泵1的入口12与负压罐2的出口11处通过管道5用法兰盘6联接,负压罐的底部8装有管4设有高于负压罐出口11的入口10,负压罐的顶面3设有带封闭装置的注水孔9,入水口10通过管4用法兰盘7联接入水箱或水池的吸水管道13。工作时,首先打开注水孔9,加水至超过出口11,用闸阀封闭注水孔9,启动水泵1抽水,罐体内开始吸水-真空-负压过程,外部大气压将水通过吸水管道13送入罐体实现连续供水。如泵停机只要闸阀不渗漏,不需再次加水即可启动水泵工作。负压罐入口可设于罐体侧壁高于出水口11处或用外部接管设于顶面3,注水孔也可设于罐体侧壁高于出水口11处。
负压吸水供水设备还可替代潜水泵工作。
