Abstract:
The system is designed to shut-off the flow of liquid in a conduit, unattended, i. e. , automatically, in the event of a liquid conduit rupture, liquid overflow, or the like. A float which carries a mercury switch is set over a recess formed therefor and into which liquid can flow and collect. The float rises with the collected liquid, and the mercury switch activates a solenoid valve which is interpositioned in a pressured-liquid conduit, to halt the flow of liquid through the conduit. The recess is formed in a lowermost portion of an area in which the subject conduit is sited.
