针对中小学校的特点,上课、下课定时,使用厕所人数集中,设计了如下简单易行的控制电路。原理如下:(如图)当上课或下课时,必须按动按钮以便打铃。当按下按钮A时,SJ吸合,J吸合,自锁。电磁阀DF吸合冲水。SJ延时断开,停止冲水。每次下课冲一次,上课铃再冲一次,每日冲水十几次。夜间、星期天无人就不冲水。达到节
In view of the characteristics of primary and secondary schools, the number of people using toilets is concentrated at the time of classes and classes, and the following simple and easy control circuits have been designed. The principle is as follows: (Figure) When the class or class, you must press the button to ring. When button A is pressed, SJ pulls in, J pulls in, and it locks. Solenoid valve DF suction flush. SJ delayed disconnection, stop flushing. Each time the class rushes, the school bell rushes again, flushing water more than a dozen times a day. No one will flush at night or on Sunday. Reach section
