[0048] When in use, connect the cold water inlet 4 to the cold water pipeline, the hot water inlet 5 is connected to the solar water replenishment pipeline, and the water outlet 10 is connected to the nozzle of the mixed water pipeline; when it is necessary to add cold water to the solar energy, turn on the cold water water switch Valve 12, that is, rotate the adjusting knob of the cold water on-off valve 12 by 90 degrees, so that the two cylindrical holes 112 on the adjusting spool 111 of the cold water on-off valve 12 are connected to the cold water inlet pipe 901 on the left and the cold water on the right. The water inlet 903 provided in the lower part of the water pipe 902 communicates, so that the left cold water inlet pipe 901 and the right cold water inlet pipe 902 are communicated, so that the cold water is respectively along the left cold water outlet pipe 601 and the left cold water inlet pipe 901 , The inlet hole 903 at the lower part of the cold water inlet pipe 901 on the left, the cylindrical hole 112 communicating with the inlet hole 903 at the lower part of the cold water inlet pipe 901 on the left, and the two cylindrical holes 112 of the cold water on-off valve 12 The through hole 113, the cylindrical hole 112 communicating with the inlet hole 903 at the lower part of the right cold water inlet pipe 902, the inlet hole 903 at the lower part of the right cold water inlet pipe 902 enter the right cold water inlet pipe 902, and then follow the hot water The outlet pipe 7 enters the hot water inlet 5 for water supply; when showering with solar water, the cold water pressure is adjusted visually to make the cold water pressure basically equal to the hot water pressure; that is, the cold water flow switch is adjusted first when using The valve 11 is closed, so that all the hot water in the mixing water regulating valve core 2 is hot water. Observe the hot water flow at the water outlet 10; open the cold water flow switch regulating valve 11, and then close the hot water outlet of the mixing water regulating valve core 2 Pipe 7, make the mixed water regulating valve core 2 all out of cold water, adjust the cold water flow switch regulating valve 11, make the cold water flow at the water outlet 10 the same as the water flow when all hot water, this state indicates cold , The pressure of the hot water is basically balanced, and then the opening of the cold water flow switch regulating valve 11 can be basically fixed. In the future, in the shower process, only need to adjust the mixing water regulating valve core 2 through the mixing water regulating valve handle 3 to obtain the required Water temperature.
