PURPOSE:To prevent a fear of a burn from being caused to a person under a delivery of hot water at the hot water supplying tap by a method wherein a normal temperature valve is arranged in a line between a hot water tank and the hot water supplying part. CONSTITUTION:A specified temperature valve 6 for mixing water with hot water fed from a hot water tank 1 and feeding a specified hot water having a specified temperature lower than that of hot water in the hot water tank 1 is arranged in a line between the hot water tank 1 and the hot water supplying part 2. This specified temperature valve 6 may perform a simultaneous adjustment of a low temperature water inlet port 8 and a hot water inlet port 9 under an arrangement of a mixing hot water heat sensitive unit 7 in the mixing chamber 10. That is, when a water temperature of the mixed hot water mixed in the mixing chamber 10 is increased, a valve plate 12 is pushed with a rod 11 of the mixed water sensing unit to expand the opening of the low hot water inlet port 8 and at the same time the opening of the hot water inlet port 9 is reduced, the water temperature of the mixed hot water is decreased. When the water temperature of the mixed hot water in the mixing chamber 10 is decreased, the rod 11 is pulled back into the mixing hot water sensor 7, the valve plate 12 is pushed by the spring 13 and the opening of the low temperature water inlet port 8 is decreased and at the same time the opening of the hot water inlet port 9 is widened to increase the water temperature of the mixed hot water. |
