Apparatus for the prevention or limitation of water damage |
摘要 |
The invention relates to an apparatus for preventing or limiting water damage caused by leakage from pipes or appliances in which a sensing element in the form of a pair of conductors having current applied thereto is positioned in an area to sense accumulation of water from leakage. The sensing element is connected to a resettable relay to operate the same when current flows between conductors of the sensing element. The relay is bi-stable and resettable and operates to disconnect the sensing element after initial conduction and to further apply heat through the heating element to a thermostatic valve to operate the thermostatic valve in a direction to close off water flow to piping or apparatus in which leakage occurs.
