触控式省水阀在综合性医院应用的除尘能力评价

目的通过触控式水阀的除尘能力研究，验证其是否适合在医院环境中使用。方法收集医院环境中的自然落尘，溶于清洁自来水中，人工将其附着于触控头上，干燥24h后开启自来水，将冲脱下来的自来水分段收集，检测其浊度和电导率，观察洗脱效果。结果附着物能在20s内被快速洗脱，将自来水的吸光度值降为零，电导值降到0．018s／cm．清洁度与原自来水检测值一致。结论触控式水阀具备自动除尘能力，能在综合性医院安全应用。

Dust capacity evaluation of HP185-S valve applications in the general hospital

Objective To verify the touch valve applications in the general hospital through dust capacity evaluation.Methods We have collected natural dust in hospital and dissolved it in clean water.We then made it attached to the head of touch valve.Twenty-four hours later,we eluted and sub-collected the dust by water,and measured its turbidity and conductivity to observe the eluting effect.Results Attachments can be quickly eluted in 20 seconds,and its cleanness is the same as water with the OD of the water decreasing to zero and the conductance decreasing to 0.018 s/cm.Conclusion Touch valve can automatically clear away the natural dust and it can be safely used in the general hospital.
