Abstract: The invention is a kind of water piping device for high water tower, specifically a kind of water piping device for naturally transporting water from the lower location to the higher location for water supply without auxiliary power. The invention is characterized that: configuring a closed water tank at the lower position and a water tower at the higher position; and, the water tank and the water tower are connected by a water duct and a pressure-releasing pipe. The water tank is provided with an inlet pipe and an outlet pipe in which the intake pipe is connected with the tap water pipe and the outlet pipe is connected with an electromagnetic valve and penetrating the bottom water tank of the water duct and protruded from the bottom water tank and providing a bolt for screw-sealing. The water duct is configured according to the height of water tank and the water tower and welded with separated sealed tanks in the water duct that the neighbored two water tanks is penetrated with a connecting pipe; therefore, forming an opened room between two water tanks so that the top end of connecting pipe can be easily penetrated in and screw-sealed by a bolt; and, the bottom end of the connecting pipe is penetrated at the bottom of the lower water tank; configuring a penetration hole at a certain location on the upper pipe of the upper water tank and a connecting pipe in the water tank at the top end of the water duct. One end of the connecting pipe is protruded from the top end water tank and the other end is connected to the inner ring wall of the pressure-releasing tube; and, configuring an inlet hole at certain location on the upper end of the top end water tank and an exhaust pipe penetrating the inner ring wall of the pressure-releasing wall. The upper end of exhaust pipe is penetrated outside the top end of pressure-releasing tube and screw-sealed with a bolt; the inner ring wall is protruded downward integrally with the top end of pressure-releasing tube and keeping a certain distance from the bottom of the pressure-releasing tube. Configuring a water pipe on the pressure-releasing tube which is controlled by an electromagnetic valve for opening and closing; the other end of water pipe is connected to the water tower that the water in the water tower can be imported into the bottom end water tank of the water duct through the penetration hole of outlet pipe. When the end of outlet pipe is surging, using the bolt to screw-sealed the end of outlet pipe so that the water can be imported into the next water tank by the pressure of water tank through the pipe end of connecting pipe; and so forth, to fill each water tank of the water duct; then, the water is imported to the inner ring wall of pressure-releasing tube from the top end water tank; and, when the pressure-releasing tube is filled water to the height of the water pipe, using the bolt to screw-sealed the exhaust pipe at the top end and opening the electromagnetic valve to import the water into the water tower by the water pipe so as to store water in the water tower for supplying water to each water consumption areas. When the water level of water tower reaches a certain height, closing the water pipe and the electromagnetic valve of the outlet pipe so as to balance the pressure of pressure-releasing tube and the water tank and make no water backflow and supplying water again by opening the electromagnetic valve. Therefore, the invention can transport the water from lower location to the high location without auxiliary power so as to reduce the power consumption.
