节水器(见图1)是我厂自行设计安装的。采用这种节水器之后,东楼厕所的用水量大幅度下降。由原来的每月1836吨下降到92吨,节水效率达94％,每天耗电0.7度,运行稳定。成本大约600～700元,2～3个月就可回收成本。节水器是控制水箱给水管。在给水管上安装电磁阀,电磁阀在节水器的控制下按照一定的规律启闭,可根据班次和季节任意调整。工作原理(见图2)由A、B、C、D四个时 The water-saving device (see Figure 1) is designed and installed by our factory. With the use of this water-saving device, the water consumption in the toilets of the East Building has dropped significantly. From the original 1836 tons per month to 92 tons, the water-saving efficiency reached 94%, and the power consumption was 0.7 degrees per day. The operation was stable. The cost is about 600 to 700 yuan, and the cost can be recovered within 2 to 3 months. The water saver is a control tank feed pipe. A solenoid valve is installed on the water supply pipe, and the solenoid valve is opened and closed according to a certain rule under the control of the water-saving device, and can be arbitrarily adjusted according to the frequency and the season. Working principle (see Figure 2) from A, B, C, D four times
