1、 I PH 在线检测仪的在线检测仪的结构设结构设计计 摘要摘要 随着人们生活水平的提高， 人们对饮用自来水的饮用要求有了进一步提高。 高精度稳流 器是为检测自来水三个主要测量标准（含氯量、浓度、PH 值）中的含氯量而进行研制。其 主要功能是使随机性较大的水速流至稳流器后的到某一基本恒定的均速。 以使于随时方便地 检测自来水的含氯量。 该产品是在原先进的设备基础上进行的大胆的改进而成。经几个月的研制、检测，结果 表明它不但能很好地满足技术要求， 达到出水均速约 30 升/小时。 而且结构比原型更为简单， 且安装方便，外型上也做了一定的改进。 本报告主要讨论稳流器的设计过程中发现的问题， 同时对产
