<p>The device (20) has a mechanical actuator (30) connected to an electrical switch (35) for turning an electrical solenoid valve (36) ON and OFF to open and close a water feed line (23). The water feed line is connected to the valve body (26) of a water tap valve (25). An upstream line (37) is connected to the opening (39) of a drain valve (40) which is closed based on water flow in the upstream line. The opening of the drain valve automatically opens when the water in the upstream line is below a certain water pressure to drain water. The mechanical actuator is perpendicularly connected to the valve body and to a regulating body (45) arranged in the valve body. The regulating body is connected to a water discharge line (31) for adjusting flow of discharged water. A passage (46) is formed between the water inlet (27) and water outlet (28), and opens and closes based on the operation of the mechanical actuator.</p> |
