目前大便器的水箱零件构造尚存在一些缺点,主要是容易漏水,造价也较高。采用阀门直接冲洗便器,具有较好的冲洗性能,造价也较低,但在应用上必须有防止污染水质的措施。为了解决这个问题,早在1965年北京市建筑设计院与原北京市建筑装配公司就共同进行试验研究,把直接连接便器的冲洗管分为压力管及冲洗管两个部分,如图1所示。由于给水压力管不与便器直接连接,压力管插入冲洗管后周围尚有足够的空隙,使冲洗管内与大气相通。当给水管
At present, there are still some shortcomings in the construction of the water tank parts of the toilets, mainly because they are prone to water leakage and the cost is high. The direct flushing of the toilet with the valve has better flushing performance and the cost is lower, but there must be measures to prevent pollution of the water quality in the application. In order to solve this problem, as early as in 1965, the Beijing Institute of Architectural Design and the original Beijing Building and Assembly Company jointly conducted a pilot study, and the flushing pipes directly connected to the toilet were divided into two parts: the pressure pipe and the flushing pipe, as shown in Figure 1. . Since the water supply pressure pipe is not directly connected with the toilet, there is still enough space around the pressure pipe to insert into the flush pipe, so that the flush pipe is connected to the atmosphere. When the water supply pipe
