<p>An improved portable fire hydrant (10) that can operate a water main valve disposed within a water main (11) to produce water for fighting a fire by rotating a valve stem (24) coupled to the water main valve includes an extension (30) through which water can flow when the fire hydrant is coupled to the water main. The portable fire hydrant may also include a sealing mechanism (32) disposed on the extension that seals the portable fire hydrant to the water main. A valve operator (38) may also be coupled to the portable fire hydrant and attached to a valve rod (40) that extends down through the extension of the protable fire hydrant. Disposed on the end of the valve rod may be a coupling mechanism (42) for coupling the valve operator to the water main valve. When the portable fire hydrant is attached to the water main, the valve operator of the portable fire hydrant is coupled to the water main valve so that manipulation of the valve operator will cause the water main valve to reposition. This enables fire fighting water to be provided from the water main to the portable fire hydrant. The fire hydrant may also have an aligning mechanism (36) for properly aligning the hydrant with the water main, and an attaching mechanism (34) for rigidly attaching the fire hydrant to the water main.</p> |
