保温水箱根据使用加工的材料的不同可以分为：不锈钢保温水箱 承压保温水箱 玻璃钢保温水箱。 由高水箱、存水箱和低水箱三部分组成。高水箱内设有机械控制的润水器、冲水阀和泄水阀以及电极浮子开关，润水器和冲水阀的阀座分别与设置在存水箱内的三通冲水管连接，泄水阀开启，高水箱与存水箱连通；低水箱内设置杠杆式浮子开关，浮子阀芯开启，存水箱与低水箱连通；低水箱内还设有潜水泵、过滤器和排污管，潜水泵出水管口位于高水箱内，潜水泵的关闭通过高水箱内的电极浮子开关控制。
According to the different materials used, the thermal insulation water tank can be divided into: stainless steel thermal insulation water tank, pressure insulation water tank, FRP insulation water tank. It consists of three parts: high water tank, storage tank and low water tank. The high water tank is equipped with mechanically controlled wetters, flushing valves, drain valves and electrode float switches. The seat of the wetters and flushing valves are respectively connected with the three-way flushing pipe set in the water storage tank, and the discharge valve is opened, and the high water tank is connected with the water storage tank; the low water tank is equipped with lever float switches, the float valve core is opened, and the water storage tank is connected with the low water tank; the low water tank is also equipped with a diving tank. Pump, filter and sewage pipe. The outlet pipe of submersible pump is located in the high water tank. The closure of submersible pump is controlled by the electrode float switch in the high water tank.
