实用新型内容
本实用新型主要解决的技术问题是提供一种浮球开关，结构简单，安装方便，无需维护，不会随着进水所引起的振荡而造成频繁启动、浮球本体回转等的误操作，且液位调节区间较大。

在本实用新型一个较佳实施例中，所述壳体包括上壳体和下壳体，所述下壳体上设置有定位孔和定位销，所述上壳体设有与下壳体对应的定位孔和定位销，所述上壳体和下壳体通过焊接方式固定，内部形成封闭的腔体。
在本实用新型一个较佳实施例中，所述壳体的出口端灌入一定量的密封胶，所述过线挡板阻挡密封液浸入浮球开关内部。
在本实用新型一个较佳实施例中，当水位上升时，所述球体滚入上分度调整板以及中间分度调整板之间，球体撞击拨杆使其圆周摆动，同时促动微动开关启动，故而启动外部电器。
在本实用新型一个较佳实施例中，当水位下降时，所述球体滚入中间分度调整板与下分度调整板之间，球体离开拨杆，微动开关弹开拨杆并断开电路，外部电器停止工作。

本实用新型的有益效果是：本实用新型指出的一种浮球开关，具有以下优点：
1、浮球开关为广角工作类型，可准确的监测特定的水位，或应用于污水泵的自动控制水位系统中，并具有防漏电、防震、耐冲击及耐化学腐蚀的优点；
2、不会随着进水所引起的振荡而造成频繁启动、浮球本体回转等的误操作，且液位调节区间较大；
3、去除污的外表面设计可确保在较为恶劣的环境中正常使用；
4、由于内置配重存在，可使得浮球开关在工作中不会受外部污水槽中水的振荡影响，并能保持稳定且不失效；
5、浮球开关启停较其他传统的浮球开关更为精确，且在电源线定位长度远比其他的浮球开关的定位长度要短，适用于较窄的环境中工作，浮球体积较大，浮力大，即使被杂物所附着也能正常工作，因为其除污的外壳设计，在正常工作中可将附着于外壳表面的杂物去除，传统浮球因为需要摆动的空间较大，容易被工作环境的大小所限制，且易被其他杂物所干扰失效；
6、由于浮球开关内部结构简单，外部结构不易损坏且零部件较少的原因，电气寿命和机械寿命远远高于其他结构复杂的浮球开关，具有结构简单，安装方便，成本低的且电气寿命和机械寿命长的特点。

所述壳体内设有多个加强筋结构，使得整体结构非常牢固，壳体本身的体积较大所产生的浮力也较大，故而即使有异物的撞击或者其他杂物一瞬间的挂住也能正常工作。
所述壳体包括上壳体2和下壳体3，所述下壳体3上设置有定位孔10和定位销11，所述上壳体2设有与下壳体3对应的定位孔10和定位销11，所述上壳体2和下壳体3通过焊接方式固定，内部形成封闭的腔体。

所述壳体内设置有微动开关6、拨杆7以及球体8，所述球体材质为45#钢，直径为25.4mm，所述拨杆7设置在微动开关6和球体8之间，所述拨杆7可以在一定的角度下自由旋转，所述壳体内部还设置有分度调整板，所述分度调整板包括上分度调整板9、中间分度调整板12和下分度调整板13，所述中间分度调整板12的高度分别大于上分度调整板9和下分度调整板13的高度，当水位上升时，所述球体8滚入上分度调整板9以及中间分度调整板12之间，球体8撞击拨杆7使其圆周摆动，同时促动微动开关6启动，故而启动外部电器；当水位下降时，所述球体8滚入中间分度调整板12与下分度调整板13之间，球体8离开拨杆7，微动开关6弹开拨杆7并断开电路，外部电器停止工作，在 水位上升及下降过程中，所述球体8始终在分度调整板形成的通道中滚动，不会因此滑落到浮球开关内部的其他空间，并保证浮球开关正常的连续工作起停。
所述壳体下部设置有挡板14，当水位下降时，球体8滚入中间分度调整板12与下分度调整板13之间时，可防止球体8滚入浮球开关内部其他空间。
所述挡板14与壳体底部形成可放置配重的空腔，放置配重增加浮球开关的整体重量，使得浮球开关在较恶劣的工作环境下不受进水引起的振荡而频繁启动。
综上所述，本实用新型指出的一种浮球开关，具有以下优点：
1、浮球开关为广角工作类型，可准确的监测特定的水位，或应用于污水泵的自动控制水位系统中，并具有防漏电、防震、耐冲击及耐化学腐蚀的优点；
