水流开关使用说明书
概述：3S系列液体水流开关用于流经管道的液体流量变化，例如水、
乙二醇或其它非危害性液体。
当液体流量超过或低于设定的流量值
时，其单刀双掷开关触点（SPDT）可使一个回路导通，而同时切断
另外一个回路。
该水流开关通常使用在需要连锁作用或“断流”保护
场所。

⏹水流开关的安装
●3S系列水流开关采用NPT 密封螺纹管路接头，有1英寸、4分、6分三种规格，用户订货时选
择与管径配套的接头。
●外壳的箭头方向应与管路内流向一致
●水流开关应安装在水平管路上。
如必须安装在垂直管道上，则液体流向应向下往上流。
绝不允许
安装在自上往下流向的垂直管路上。
●水流开关在使用中绝不允许流向倒流，以免造成叶片反向断裂。
附：叶片修整图：

其余尺寸为修正用
休整后的叶片安装时，其顶端不得与管壁有任何摩擦，且与管壁底部有5~10mm间隙接线图：
典型安装图：
⏹水流开关的调节
1、打开水流开关外壳；
2、开关出厂时已设定在约为最小流量值。
调高流量设定值，顺时针旋转调节螺丝①；
3、按动挡片来检查微动开关是否能正常工作，过多的逆时针旋转调节螺丝，可能导致流量开关失效；
4、安装结束后，请通过按动流量开关杠杆数次来检查，一旦发现杠杆回复时没有“咔嗒”声，顺时针旋转调节螺丝直到回复时有“咔嗒”声；
5、禁止取出调节螺丝固定夹②，否则将造成流量调节螺丝失效；
6、漆封的调整螺丝③仅供出厂调整水流开关状态，请勿改变或调节；
7、应观察三个工作周期，确定开关和与之连接的系统运转正常，并及时盖上开关外壳。
水流开关调节注意问题
水流开关上面的调节螺丝其基本作用是可以调节其灵敏度。
1.更精确地讲上面的螺丝③是用来调节微动开关的，一般建议请勿改变或调节。
2.下面的螺丝①是用来调节传感元件-波纹管松与紧的程度。
用户需要根据不同的水流量工况进行调节。
一般来説比调节成比较松的波纹管，不大的水流量就可以推动水流开关杠杆，并通过波纹管传递给微动开关。
使微动开关进行切换动作。
反过来调节成比较紧的波纹管，需要相对比较大的水流量。
才能推动水流开关杠杆，并通过波纹管传递给微动开关。
使微动开关进行切换动作。
