The comparision experiment is performed between curving narrow strip float valve and F1 circular float valve in an experiment tower of (1000mm)×(350mm) by employing a tipcal model experiment system of water-air. From the experiment, many hydraulic properties, such as tray pressure drop, entrainment rate and weeping rate are gained, and mass transfer tray efficiency is calculated through the method of oxygen-desorption. The downcomer area in the experiment tower is (7.97%), with weir height (50mm), ascending height of the curving narrow strip valves (9mm), and the hole ratio (11.89%). The varying scope of main parameters are: liquid flow strength 0～0m^3/(m·h)), gas velocity 0～(3m/s). The absorption tower with (200mm) diameter is equipped with pall packings. From the experiment, it can be seen that compared with the plate equipped with F1 circular float valve, the tray efficiency of curving narrow strip float valve is higher, pressure drop is lower, and processing capability is higher.
