摘　　要：介绍了智能节水阀门的工作原理,针对控制元件在与土壤水分交换时速度慢的缺点,采用使控制元件与空气进行水分交换的方法来提高控制元件的湿感灵敏度,从而有效地进行灌溉作业。The working principle of intelligent water-saving valves is introduced. In view of the problem with the slow speed of water exchange between control elements and soil, the wet sensitivity of the control elements is improved by means of the water exchange between the control elements and air, thereby effectively conducting irrigation operations.

关 键 词：智能节水阀门 控制元件 水分交换
