The specific embodiment
Below in conjunction with a preferred embodiment and accompanying drawing the utility model is described further, to help understanding the utility model content.
As shown in Figure 1, the equipment of the utility model relation of installing is: this device comprises cooler I 7 and cooler II 8, and cooler I 7 is equipped with mixer with cooler II 8 inside, and cooler I 7 is provided with discharge port with cooler II 8 bottoms; The water inlet of cooler I 7 is connected with two water pipes, is separately installed with valve I 1 and valve II 2 on the water pipe; The delivery port of cooler I 7 is connected with two water pipes, and wherein a water pipe is provided with valve V 5, and another root connects the water inlet of cooler II 8; The water inlet of cooler II 8 is connected with two water pipes, is separately installed with valve III 3 and valve IV 4 on the water pipe; The delivery port of cooler II 8 is connected with two water pipes, and wherein a water pipe is provided with valve VI 6, and another root connects the water inlet of cooler I 7.
