PURPOSE:To permit to supply hot-water without lowering the temperature of the hot-water by a method wherein water is not supplied while supplying the hot- water even when the opening and closing operations of a water feeding valve are not effected due to an automatic control covering from the supply of the hot-water to the feeding of the water. CONSTITUTION:The hot-water is supplied while leaving the water feeding valve 1 opened. Even if the water feeding valve 1 is being opened, a float valve 12 is closed by the hydraulic pressure of a hot-water reserving tank 3 during supplying the hot-water, the water level of an upper float tank 8 is kept, water is not fed and the total volume of the hot-water may be supplied without lowering the temperature of the hot-water. When the hot-water in the hot-water reserving tank 3 is emptied, the hydraulic pressure is eliminated, the float valve 12 is opened, the water level of the upper float tank 8 is lowered and the float valve 2 is opened to feed the water. When the hot-water supplying valve is used under leaving it opened, the device may be used as a water feeding device. Further, if the water level of the hot-water reserving tank 3 is lowered to any position because of the supplying of the hot-water for showering or the like, an orifice 9 acts in accordance with the variation of the level of the float tank 8 to lower the level thereof with a time delay and supply the water to the hot-water reserving tank 3. When the tank 3 is filled fully, the float valve 2 acts automatically to stop the feeding of the water and keep a self-equilibrium. |
