Thermal activated cold water diversion valve

摘要

A device that directs cooled and otherwise wasted water to storage for reuse is disclosed. The valve incorporates a single flow stream through internal piping around a thermally sensitive coil which imparts rotation for automatic closing of a valve upon arrival of heated water to the valve. Once closed, the device resets itself for the next activation and use. The device is basically self contained and requires only single point installation. The unit provides for many households to experience substantial saving on daily energy and water expenses. The installation can be readily retrofitted to existing structures or incorporated in new construction whether any be homes, apartments, hotels, condominiums and businesses with water distribution requirements. Further, the present invention, requiring no external energy input, offers an alternative to expensive circulating hot water systems incorporating substantial initial cost and extended energy consumption.

主权项

1. A water recovery device for diverting and storing water from a hot water delivery line comprising:
a manually activated knob to initiate within the water delivery device a flow of a stream of water from the hot water delivery line into an internal metal tube in the water delivery device; and next into an internal split metal tube surrounding a thermal sensitive bimetallic coil, the bimetallic coil automatically activates, upon the arrival of heated water from the hot water delivery line, an internal ball valve, wherein the split metal tube maintains the water stream within the confines of the tubing, avoiding unnecessary water contact with the thermostatic coil; resulting in protection of said critical moving parts of the thermostatic coil from being jammed by any calcium-like impurities which may exist in the water stream; further, the stream of water flows through the internal ball valve and out to a reservoir to receive and hold the diverted water for later use; and said ball valve rotates interactively from the action of the bimetallic coil to close the stream of water upon heated water reaching a predetermined temperature without having wasted any water along the process.
