Abstract: PURPOSE:To eliminate the trouble caused by the precipitation of Ca by providing the water supply port and water discharge port communicating with either one of a cathode chamber and an anode chamber to one end and other end of the electrolytic cell constituted of the cathode chamber and the anode chamber partitioned by an electrolytic diaphragm. CONSTITUTION:When a water taking-in opening and closing means 9 of an electrolytic unit is opened, the water of a valve operating chamber 20 flows out because the pressure on the downstream side of the valve seat of a main dynamic valve chamber 15 is lowered and the valve member 18 integrated with a diaphragm 19 closes the valve seats 21a, 21b of the respective valve chambers 15, 16 simultaneously with the upward movement of the diaphragm 19. When the opening and closing means 9 is closed, the water pressure on the downstream side of the valve seat of the main dynamic valve chamber 15 rises and water flows in the valve operating chamber 20 through a passage 23. Therefore, the valve member 18 is pressed in the direction of the valve seat by the pressure of the valve operating chamber 20 to simultaneously close the valve seats 21a, 21b of the valve chambers 15, 16. The electrolytic current to the electrolytic unit 1 is turned ON and OFF by the signal of a signal transmitter generated by the movement of the valve member 18.
