The utility model discloses a differential guiding floating valve tower plate, which is characterized in that the length A of the guiding floating valve of the tower plate comprising a branch corner is between 30 mm and 120 mm, the width b is within 15 mm and 50 mm, the width C of a back leg of the guiding floating valve is between 15 mm and 50 mm, and the width D of a front leg of the guiding floating valve is between 8 mm and 45 mm and is simultaneously smaller than C; the guiding floating valve is provided with a guiding hole, and the opening direction of the guiding hole makes the gas from the guiding hole the same as or perpendicular to the liquid stream direction on the tower plate. Different areas on the tower plate are also provided with two kinds of float valves of which the front legs have different specification in suitable ratio aiming at different liquid flow intensity. The utility model can eliminate liquid level gradient and liquid stagnation areas on the tower plate and has the advantages of making steam liquid contact uniform, having no abrasion on valve legs, etc., and the utility model greatly improves the integrated operation performance of whole towers.
