【技术实现步骤摘要】
本技术涉及一种适用于自来水塔或水箱的液位自动控制装置。现有的自来水塔或水箱的液位控制装置由传感器、液位显示器、接触器等组成,这种电子控制装置使用元器件多,易出故障,且结构复杂,成本高、安装复杂。本技术的目的是提供一种结构简单,造价低,安装方便,使用可靠的液位自动控制装置。本技术由壳体、浮球、滑杆组成。壳体(5)内装有磁铁(2),滑杆(6)的上部装有铁片(4),滑杆(6)的下部固定浮球(11),浮球(11)与浮球(12)由软质线连接,连线(13)的长度为所需控制的设定水位的高度。浮球(12)的重力应能克服磁铁(2)对铁片(4)的吸力,壳体(5)的上部装有磁铁(2),静触片(9)固定在壳体(5)内的台阶上,并连结导线(10),动静片(8)为条形,一端固定在壳体(5)的台阶上,连接导线(10’),另一端装有绝缘传动件(7)。本技术安装在自来水塔或民用水箱上部,当塔内水位到达设定高度时,浮球(11)浮在水面上,浮球(12)可悬浮在水中,也可同时浮在水上。铁片(4)被磁铁(2)吸住,铁片(4)通过绝缘传动件(7)将动触片(8)顶起,动触片(8)与静触片(9)脱开,电路断开,水泵不工作。当塔内水位下降,浮球(12)随着水位下降,下降到浮球(11)与浮球(12)之间的连线(13)被拉直时,滑杆(6)与铁片(4)一起下滑,使铁片(4)与磁铁(2)断开,动触片(8)与静触片(9)接触,电路导通,水泵工作。本技术另部件少,结构简单,造低廉,安装方便,使用可靠。附图为本技术结构示意图。图中(1)为壳盖,(2)为磁铁,(3)为垫片,(4)为铁片,(5)为壳体,(6)为滑杆, ...
