    The automatic valve for water tank is an automatic "gate" mounted on the upper part of the water inlet pipe and comprised of a small fixed magnetic sheet, sealing sheet with a hole, and a movable sheet which can freely move up and down. When the sealing sheet moves down and tightly contacts with the holey sheet and the magnetic sheet, the water inlet pipe is closed. Once the water level rises to required limit and the water pressure is greater than the magnetic attraction ofthe magnetic sheet, the sealing sheet is pushed away from the sealed hole, and thus the water in the tank can be drained off due to the siphon phenomenon in water drain pipe.
