Specifically, the hot water inlet 111 of the first pipe 110 and the water return outlet 221 of the fourth pipe 220 may face the same side.
As shown in fig. 3 to 5, the three-way valve 400 includes:
the first channel 410 and the first channel 410 are respectively communicated with the water inlet channel 100 and the water return channel 200, specifically, the first channel 410 is respectively communicated with the first pipe body 110, the second pipe body 120 and the fourth pipe body 220, and is vertically arranged, the first pipe body 110 is located between the second pipe body 120 and the fourth pipe body 220, namely, two ends of the first channel 410 are respectively communicated with the second pipe body 120 and the fourth pipe body 220, and a communicated end of the first pipe body 110 and the first channel 410 is located between the second pipe body 120 and the fourth pipe body 220.

The valve portion 430 includes a first valve portion 431 and a second valve portion 432 communicating with each other, the first valve portion 431 has a smaller diameter than the second valve portion 432, the first valve portion 431 and the second pipe body 120 are oppositely disposed, the second valve portion 432 and the fourth pipe body 220 are oppositely disposed, an external thread is provided on an outer wall of the second valve portion 432 to be screw-coupled to the first channel 410, the first pipe body 110 is oppositely disposed to the first valve portion 431, and since the first valve portion 431 has a smaller diameter than the second valve portion 432, water in the first pipe body 110 can flow into the second pipe body 120 from between the first valve portion 431 and the first channel 410. It should be noted that the opposite ends of the first valve portion 431 and the second valve portion 432 are connected to be flush with the end of the first channel 410 communicating with the second tube 120.
The first valve rod 420 comprises a rod 421, a first closing part 422 and a second closing part 423, the first closing part 422 and the second closing part 423 are respectively sleeved on the rod 421, the first closing part 422 is positioned inside the second tube 120, and is located at one side of the end of the first passage 410, the diameter of the first closing member 422 is larger than that of the first passage 410, and the first closure member 422 is provided with a through hole 4221, the second closure member 423 being located inside the first valve portion 431, and the two sizes are matched, the rod 421 drives the first sealing element 422 and the second sealing element 423 to move along the direction of the first channel 410 respectively, and the first closure 422 abuts the end of the first channel 410, the second closure 423 moves from inside the first valve portion 431 to inside the second valve portion 432, at which point the water located inside the fourth tube 220, the interior of the first valve portion 431 is accessible through the second valve portion 432 and from the through hole 4221 in the first closure 422 into the interior of the second tube body 120. When the first valve rod 420 moves in the reverse direction, the second sealing member 423 located in the second valve portion 432 moves into the first valve portion 431, and at this time, the water located in the fourth pipe 220 cannot enter the second pipe 120 through the valve portion 430.
The elastic means 440, including a spring, is installed on the second body 120 and is in driving connection with the first valve rod 420, so that the first valve rod 420 is moved against the elastic force. The water flow direction of the hot water inlet 111 is the same as the acting force direction of the spring, so that the phenomenon of back suction of the first valve rod cannot be caused due to the increase of the pressure difference. And meanwhile, the design of high-temperature and low-temperature water isolating cores is added, so that high-temperature and low-temperature water is isolated, the problem of back suction of the valve core is solved, and the normal operation of the three-way valve is ensured.
It will be understood by those skilled in the art that when the temperature sensing probe 300 detects that the temperature is higher than the set temperature, the temperature sensing probe 300 controls the first actuator 450 to drive the first valve rod 420 to move. The first actuator 450 is disposed outside the second tube 120 and is in transmission connection with the rod 421 through the elastic device 440, and in addition, the first actuator 450 can be manually rotated to drive the first valve rod 420 to move along the axial direction of the first channel 410.
As shown in fig. 4 and 5, when the temperature sensing probe 300 detects that the temperature is higher than the set temperature, the temperature sensing probe 300 controls the first actuator 450 to drive the first valve rod 420 to move towards the second valve part 432, and the first sealing element 422 abuts against the end of the first channel 410, and the second sealing element 423 moves from the inside of the first valve part 431 to the inside of the second valve part 432, at this time, water in the fourth pipe 220 can enter the inside of the first valve part 431 through the second valve part 432, and enter the inside of the second pipe 120 through the through hole 4221 in the first sealing element 422, so that high-temperature water and low-temperature water are mixed and enter the floor heating coil. When the temperature sensing probe 300 detects that the temperature is lower than the set temperature, the first actuator 450 is controlled to drive the first valve rod 420 to move in the reverse direction, and the second sealing member 423 in the second valve portion 432 is moved into the first valve portion 431, so that the water in the fourth pipe 220 cannot enter the second pipe 120 through the valve portion 430.
As shown in fig. 3, the ground heating water mixing system further includes:
the second channel 700 and two ends of the second channel 700 are respectively communicated with the water inlet channel 100 and the water return channel 200, wherein the communicating ends of the second channel 700 and the water inlet channel 100 can be located on the first pipe body 110, and the communicating ends of the second channel 700 and the water return channel 200 can be located on the fourth pipe body 220.

When the second valve rod 510 abuts against the second channel 700, the end of the second valve rod 510 and the end of the second channel 700 communicating with the fourth pipe 220 abut against each other, and at this time, the water in the water inlet passage 100 cannot flow into the water return passage 200. When the end of the second valve rod 510 is far away from the second passage 700, the water in the water inlet passage 100 can flow into the water return passage 200.
When water in the fourth pipe 220 enters the second pipe 120 through the three-way valve 400, only a small amount of low-temperature water enters the heat source from the return water outlet 221, which easily causes the heat source water pump to be stuck, and reduces the service life of the water pump, so the high-temperature water entering the first pipe 110 from the hot water inlet 111 can enter the fourth pipe 220 through the second passage 700 and enter the heat source together with the low-temperature water by the cooperation of the second passage 700 and the first bypass valve 500.

As shown in fig. 6 and 7, when the third actuator 620 drives the two sides of the third valve rod 610 to abut against the inner walls of the third channel 800, the second bypass valve 600 closes the third channel 800. When the third actuator 620 drives the third valve stem 610 to deviate from the above position, the second bypass valve 600 opens the third passage 800.
When high-temperature water generated by the work of a heat source directly enters the floor heating coil through the water inlet channel 100, the service life of the floor heating coil is easily influenced due to overhigh water temperature, and the low-temperature water in the water return channel 200 can enter the water inlet channel 100 through the third channel 800 by opening the second bypass valve 600, so that the temperature of the water entering the floor heating coil is reduced. In addition, when the floor heating coil needs a larger water flow, the second bypass valve 600 can be adjusted to increase the water flow in the water inlet channel 100, so as to achieve the water flow needed by the floor heating coil.
It will be appreciated by those skilled in the art that the three-way valve 400, the first bypass valve 500 and the second bypass valve 600 can all adjust the water flow, as exemplified by the second bypass valve 600, by controlling the rotation angle of the third valve stem 610, to adjust the area of the third passage 800 that is open, and thus the water flow.
