TEMPERATURE SENSITIVE WATER SUPPLY SHUT-OFF SYSTEM |
摘要 |
An automatic water supply shut-off system includes a shut-off valve movable between opened and closed positions in a line leading from the water supply. An electric motor actuates the shut-off valve and is electrically connected to a power source through an electric circuit so that when the circuit is closed the electric motor actuates the shut-off valve into the open position to allow water flow through the line. At least one temperature sensor feeds a signal to a logic circuit that controls a switch. The switch cuts off the supply of power to the electric motor when the sensor senses a temperature corresponding to a freeze condition.
