る点である。The mixed water temperature detected by the thermistor 38 and the flow rate sensor 3
The mixing flow rate detected at 9 is sent to the setting device 4 via the controller 47.
6 is displayed. Further, when the mixing flow rate is being integrated, the controller 47 performs the integration and displays the result in the same manner. If the primary pressure of hot water or water changes due to another faucet or hot water supply faucet being used during use, the hot water side pressure regulating valve 18 or the water side pressure regulating valve 1
9 operates to maintain the secondary pressure at the set value. Therefore, since there is almost no change in the flow rate of hot water or water, there is no overshoot or undershoot of the mixed hot water temperature. Furthermore, even if the pyrotechnics are large, the hot water side motor 34 and the water side motor 35 can only output a force corresponding to the secondary pressure due to the pressure reducing action of the hot water side pressure regulating valve 18 and the water side pressure regulating valve 19. Because it is good, its ability only needs to be small. If you want to stop hot water supply, please instruct it with the setting device 46.
The hot water side motor a4 and the water side motor 35 close the hot water side valve 29 and the water side valve 30, press the valve body 32 against the valve seat 31, and stop supplying hot water. When the hot water supply is stopped, the pressure regulating valve body 20 is closed by contacting the valve seat 25, so the pressure regulating valve also does not supply hot water or hot water.
This prevents water from flowing backwards during a water outage, or from flowing into the area where the pressure is higher. The advantage of a system with such a pressure regulating valve is that, for example, when you want to dispense low-temperature mixed hot water or just water, you can set the secondary pressure up to the primary pressure of the water, so there is no difference between the hot water and water sides. Compared to the balance valve system, which balances according to the side with lower primary pressure, it is possible to obtain a higher flow rate.

Furthermore, the hot water side valve 29 and the water side valve 30 that control the flow rate include a hot water side pressure regulating valve 18 and a water side pressure regulating valve 1.
Since the pressure reduced in step 9 is applied, the resolution does not need to be coarse, and it has the advantage that it can be provided at low cost.
