在市政自来水管网压力周期性不足的地区,屋顶要设置水箱。当管网水压正常时,由管网压力直接供水,水压不足时则由水箱供水。我们称之为“高位调节水箱”。水箱在市政管网低峰负荷时进水补给,在水箱底部装有出水管和止回阀,与室内配水管网沟通。由于装有止回阀的关系,出水管只可向配水管
In areas where the pressure on the municipal water pipe network is insufficient, water tanks should be installed on the roof. When the water pressure of the pipe network is normal, the pipe network pressure will directly supply water, and when the water pressure is insufficient, the water tank will supply water. We call it “high regulation tank.” The water tank is filled with water in the low-peak load of the municipal pipe network, and a water outlet pipe and a check valve are installed at the bottom of the tank to communicate with the indoor water distribution pipe network. Because the check valve is installed, the outlet pipe can only be to the distribution pipe
