一种用于太阳能热水器的节水装置

Abstract

介绍一种用于热水器的节水装置的工作原理,该装置由温度检测系统、PlC控制系统及执行机构(电磁阀)等三部分组成。其节水的功能在于,当用户需要使用热水时,启动节水装置开关,系统自动检测并将原本储存在热水器与水龙头之间的冷水泵回主水管道,直至热水到达出水口时恢复普通使用状态,从而避免将大量冷水放流而造成的水资源浪费。

The principle of work of a water-saving device for the solar-powered water heater is presented.The device is made up of three parts: the temperature examination module,the PLC control module and the executive module(two solenoid valves).The saving water process of this device is as follows: when the user needs to use the hot water,open the switch of the device,then the device will make the cold water which between the hot water tank and the tap back to the main pipeline until the hot water gets to the tap.Then the user can use the hot water normally.In this way,lots of water waste can be avoided.
