る。The automatic opening / closing valve 21 is controlled to be opened / closed by an output signal of the flow meter 14, and a ball valve, a butterfly valve or the like which is automatically opened / closed by electric or air driving is used. If the number of open faucets 12 is small and the amount of water supplied to the faucet from the water supply pipe line 11 decreases, the control of the chemical injection amount of the chlorine sterilizer and the control of the electrolytic chlorine generation device become unstable. Or it will be difficult. Further, if the flow rate flowing through the water supply pipe 11 is extremely reduced, the speed control of the pump driving electric motor becomes impossible. Therefore, all of the faucets are closed or the number of open faucets is small, and the flow rate of water flowing through the water supply pipe line 11 is 2 times the maximum water supply amount.
When it decreases to 0 to 50%, the flow meter 14 detects this,
The output signal opens the automatic on-off valve 21, which causes a flow from the water supply conduit 11 to the water tank 10 via the branch conduit 19 to prevent a decrease in the flow rate in the water supply conduit. Then, the number of open faucets increases and the amount of water supply to the faucets increases, and the flow rate of water flowing through the water supply pipe line 11 is 50% of the maximum amount of water supply.
When it reaches -80%, the flow meter 14 detects it, and the output signal closes the automatic on-off valve 21 and closes the branch pipe line 19.

2 の範囲内で適当に選択すればよい。In this way, the pump driving electric motor M always drives the pump, the pressure gauge 18 detects the water pressure of the water flowing in the water supply pipe, and the number of opening of the faucet increases, so that the water pressure in the pipe decreases. The pressure gauge detects a decrease in water pressure and speeds up the rotation speed of the pump driving electric motor based on the output signal to drive the pump 13 so that the water pressure in the water supply pipe becomes a predetermined constant pressure, for example, 2 kg / cm 2. . Also, when the number of open faucets decreases, the pressure gauge detects the increase in water pressure in the water supply pipe and slows down the rotation speed of the pump driving electric motor with its output signal.
The water pressure in the water supply line is reduced to a predetermined constant pressure. In the meantime, as described above, the flow meter 14 detects the flow rate of the water flowing through the water supply pipe, opens the automatic opening / closing valve 21 when the flow amount decreases, and returns the flow from the water supply pipe through the branch pipe line 19 to the water tank. It is caused to prevent the flow rate from decreasing, and the speed control of the chlorine addition device and the pump driving motor is normally operated. Therefore, no matter how many faucets are opened, water containing a certain concentration of chlorine from one faucet has a constant water supply pressure, for example, 2 kg.
It comes out at / cm 2 . The water supply pressure of the faucet is 1-3 kg / cm
It may be appropriately selected within the range of 2 .
