Building water supply pipeline antifreezing system driven by circulating water pump
The invention discloses a building water supply pipeline antifreezing system driven by a circulating water pump. The building water supply pipeline antifreezing system comprises the circulating waterpump, a water supply vertical pipe, a circulating pipe, a bypass pipeline, a valve, a control box, a water meter and a municipal water supply pipe network, wherein the pipeline comprises a building piping shaft pipeline which is connected with a municipal water supply pipe network buried below a frozen earth layer and a user indoor pipeline, the circulating water pump, the check valve and the bypass pipeline are additionally arranged at the bottom of a building piping shaft, and the control box is arranged in an equipment room. According to the building water supply pipeline antifreezing system, a flow signal on the side of the household water meter is detected and is transmitted to the control box, and the circulating water pump is controlled to turn on and off by the control box, so thatinternal water forms a closed cycle I (a-b-c-d-j-h-a) when users do not use water in a water supply pipeline located at the piping shaft, and parallel flow II (one path is a-g/i, and the other path is a-h-j-f-e-d-c-b-i/g) is formed when the users use water. In two conditions that the users do not use water and the users use water in a building, water in the system flows, so that frost splitting of the water supply pipeline is prevented.
本发明公开了一种循环水泵驱动的建筑供水管道防冻系统，包括循环水泵、供水立管、循环管、旁通管道、阀门、控制箱、水表，市政给水管网，所述管道包括建筑管道井管道与埋于冻土层以下的市政给水管网连接、与用户室内管道连接，在建筑管道井底部增设循环水泵、止回阀、旁通管道，设备间设置控制箱，所述一种建筑供水管道防冻系统，通过检测入户水表侧的流量信号，将流量信号传输给控制箱，控制箱控制循环水泵启停，使位于管道井部分的供水管道在无用户用水时，内部水形成闭式循环Ⅰ(a‑b‑c‑d‑j‑h‑a)；有用户用水时，形成并联流动Ⅱ(一路为a‑g/i，另一路为a‑h‑j‑f‑e‑d‑c‑b‑i/g)。在建筑无用户用水和有用户用水两种情景下，系统中的水均实现流动，从而防止供水管道冻裂。
