Water heater tank anode construction
Abstract
Abstract A WATER TANK ANODE ASSEMBLY IS CONNECTED TO A COUPLING IN A WATER TANK WALL TO PROVIDE A SECURE MECHANICAL AND ELECTRICAL CONNECTION BETWEEN THE TANK AND THE ANODE ASSEMBLY. THE ANODE ASSEMBLY INCLUDES AN ANODE AND A CAP. THE CAP HAS A THREADED OUTER CYLINDRICAL PORTION SCREWED INTO THE TANK COUPLING. A CONICAL PROJECTION ON THE INTERIOR OF THE ANODE C AP IS IMBEDDED IN A CENTER CONDUCTING ROD OF THE ANODE TO PROVIDE ELECTRICAL CONTACT BETWEEN THE CAP AND ANODE. THE ANODE MATERIAL SURROUNDING THE ROD IS MECHANICALLY AND ELECTRICALLY CONNECTED WITH THE INTERIOR OF THE CYLINDRICAL SECTION OF THE CAP BY THREADS AND A CONDUCTIVE ADHESIVE MATERIAL. ALTERNATIVELY THE CONDUCTIVE ADHESIVE ALONE INSURES THE INTERCONNECTION OF THE CAP AND ANODE.
