SOFT-TOUCH DOUBLE-DRAIN VALVE

摘要

A soft-touch double-drain valve includes a full-drain float including a large water sealing plate covering a water discharging opening and a small water sealing plate mounted in an insertion hole. A main body includes an inner tube through hole and an adjustment hole formed therein. A partial-drain weight float includes a partial-drain adjustment press bar and an inner tube penetration hole. A first position-limiting mechanism is mounted in the main body. A second position-limiting mechanism is mounted to a full-drain push button or a partial-drain push button. An inner tube is inserted in the inner tube penetration hole, the through hole, and the insertion hole and is provided with a return spring and has a lower end operable in combination with the small water sealing plate and an upper end operable in combination with the full-drain and partial-drain push buttons to control downward movement.
