连接大便器的存水弯发生堵塞,是厕所间排水系统的常见病,尤其是公共厕所,常因管理不善而使管道受堵、积水成灾。对此,有些单位加强了管理;有些单位在技术上采取了措施,如将手拉冲洗改为自动冲洗等,均有一定的收效,但也各有不足之处。这里介绍一种节水、防堵的门动冲洗装置。门动冲洗装置主要由高水箱、导向轮、尼龙绳、羊眼圈(带圈螺丝)、电磁阀、拉线开关和塑料导线等部件组成(见图)。工作原理是:当人员进 The clogging of the traps connecting the toilets is a common disease in the drainage system of the toilets. In particular, public toilets are often blocked due to poor management and cause flooding. In this regard, some units have strengthened their management; some units have taken technical measures, such as changing the hand-washing process to automatic flushing, etc., all have certain results, but they also have their own shortcomings. Here is a water-saving, anti-blocking doorwashing device. The door moving flushing device is mainly composed of a high water tank, a guide wheel, a nylon rope, a sheep eye ring (with a ring screw), a solenoid valve, a pull wire switch, and a plastic wire and the like (see figure). The working principle is: When people enter
