基于节水马桶内外部改造的供水装置设计与分析

Design and Analysis of the Internal/External Transformation of Water Supply Devices for a Water-saving Closestool

为实现节水减排,提高生活用水的二次利用,设计了一套节水马桶的供水装置。通过优先使用盥洗池中的生活用水补给马桶水箱供水,提高水的二次利用。作品将内外2种方案进行了比较:内部方案设计连杆机构和机械水阀,对浮球阀的控制机能进行优化;外部方案改进马桶相关的管路结构,设置红外感应器自动控制注水。相比于普通马桶,该装置节水率可达21.7%,具有成本低、方便安装、无需破坏马桶结构等优点,可根据需要选择合适的方案。

In order to improve water reusing rate and achieving water - saving and wastewater discharge reducing, it has designed a whole set of water supply devices for a water - saving closestool, which enhances water reusing rate dramatically by giving priority to the used domestic water instead of tap water. It compares the internal method with the external one： the internal one optimizes the control function of float valve by designing the newly link mechanism and mechanical valve; the external one improves the toilet - related piping structure and sets the infrared sensors to control the automatic water injection. Compared to the ordinary closetool, its theoretical water saving rate is up to 21.7%. Furthermore, it provides the closetool with a low cost, easy and nondestructive installation, which can make people easier to choose the appropriate way as needed.
