PROBLEM TO BE SOLVED: To provide a two-waterway ball tap attached to a low tank of a flush toilet or the like, which can make concurrent use of clean water and intermediate water, and which enables both the sanitary supply of clean weater and the efficient supply of intermediate water. SOLUTION: The two-waterway ball tap is provided with an intermediate water line and a clean water line, and the first valve 3 for the intermediate water and the first valve 4 for the clean water share a float 5. The opening and closing of the first valve 3 for the intermediate water and the first valve 4 for the clean water is performed simultaneously. A piston 6 is usually positioned to the first valve 3 side for the intermediate water because of the repulsion of a spring 7, and the second valve 4 for the clean water is in an opened state. When the float 5 is lowered and the intermediate water and the clean water are supplied simultaneously, the piston 6 is pushed and released to a discharge opening 13 for the intermediate water by water pressure. Then the second valve 8 for the clean water is closed and the supply of the clean water is stopped. When the intermediate water becomes empty, the piston 6 is returned to the first valve 3 side for the intermediate water because of the repulsion of the spring 7. Then the second valve 4 for the clean water is opened, and the clean water is discharged from a discharge opening 14 for the clean water. When the water level rises to a predetermined level, the float is raised. Thus, the supply of the clean water is stopped, and water supply is completed. COPYRIGHT: (C)2008,JPO&INPIT
