[0035] ① This embodiment provides a method for self-adaptive adjustment of the temperature of the dam heat exchange medium, as shown in the attached figure 1
[0036] Shown:
[0037] When the high-temperature water flowing out of the low-temperature water outlet pipe 5 is more than the high-temperature water inlet pipe 6, the first control valve 12, the second control valve 14 and the third control valve 15 can be opened simultaneously, and the fourth control valve 15 is used as a control valve for excess water. The discharge pipeline controls the flow at the same time; in extreme cases, when the high-temperature water inlet pipe 6 does not need cooling water at all, the second control valve 14 can be directly closed, and the first control valve 12 and the third control valve 15 are fully opened to make the low-temperature water outlet pipe 5 The high-temperature outlet water directly flows back to the low-temperature return water main pipe 10 and enters the cooling water sta...

[0045] This embodiment provides a method for self-adaptive adjustment of the temperature of the dam heat exchange medium, as shown in the attached figure 2 Shown:
[0046] ①When the circuit passes water clockwise, the sixth control valve 27 takes low-temperature water through the low-temperature water inlet pipe 4, takes part of the return water through the low-temperature outlet pipe 5 and the sixth pipe 30 for mixing, and passes through the fourth pipe 28 to the third concrete Block 20 provides cooling water at the required temperature; at this time, the sixth pipeline 26 is closed, and the return water flows back to the low-temperature return water main pipe 10 through the second pipeline 25 and the low-temperature outlet pipe 5 .
[0047] ②When the circuit passes water counterclockwise, the fifth control valve 23 takes low-temperature water through the low-temperature water inlet pipe 4 and the sixth pipe 26, takes part of the return water through the low-temperature outl...
