and a temperature controller 33 connected to the electric control valve 34, the temperature sensor 32, and the water flow switch 31, respectively, wherein the temperature controller 33 controls the flow rate of the electric control valve 34 according to the water temperature detected by the temperature sensor 32.

Preferably, the water storage tank 2 is connected with an overflow pipe, and the overflow pipe is connected with a cooling tower water pool 7. And the redundant condensate water overflows to a water collecting tank of the cooling tower to be used as cooling circulating water.
In order to conveniently control the water level of the raw water tank 1 in the pure water station, a liquid level control valve is arranged on the mixed water pipe 5, and the liquid level control valve controls the water level according to the liquid level in the raw water tank 1.
The utility model discloses water supply system operating principle of water purification station:
condensed water of about 60 ℃ generated by the heat exchange station is sent into the water storage tank 2 for storage through a condensed water inlet pipe 21, and the redundant condensed water overflows to a water collecting tank of the cooling tower to be used as cooling circulating water.
When the pure water station starts to produce pure water, the liquid level control valve opens to start replenishing water into the raw water tank 1 as the water level of the raw water tank 1 decreases.
