water enters the filter screen from the floor drain cover to be filtered, the filtered water can enter the inner part of the upper shell, after the water amount reaches a certain height, the floating force of the floating ball separates the sealing cylinder from the fixed cylinder, and the water enters the fixed cylinder to enable the rotating fan blades to rotate; the rotating fan blades rotate to enable the rotating shaft to rotate, the rotating shaft enables the lower-layer flow distribution discs to rotate, and the rotating angles of the lower-layer flow distribution discs are adjusted according to the water flow rate, so that the openings of the upper-layer flow distribution discs and the lower-layer flow distribution discs gradually correspond to each other, and the water discharge is increased; when the lower-layer splitter disks rotate, the gears can be driven to roll in the arc-shaped rotating grooves, and the coil springs can accumulate force while rolling; when the lower-layer distribution disks rotate to be aligned with the arc-shaped openings of the upper-layer distribution disks in the vertical direction, the rotation is stopped, and the maximum water discharge is achieved; when the lower-layer distribution disks rotate to the maximum angle, the gear can be contacted with the inner wall of the arc-shaped rotating groove to stop rotating;

when the drainage is finished, the water seal shell descends, the force of the coil spring drives the gear to rotate reversely in the descending process, and the rotation of the gear drives the lower-layer shunt disks to return to the initial position;

when the lower pipeline explodes or generates large water overflow, the impact force of the explosion or the impact force generated by the large water overflow can make the upper-layer splitter disks and the plurality of lower-layer splitter disks ascend, so that the upper-layer splitter disks and the second sealing gasket are contacted with the first sealing gasket to form sealing, and meanwhile, the impact force of the splitting under the influence of the bearing plate can be continuously split under the influence of the dislocation of the upper-layer splitter disks and the plurality of lower-layer splitter disks to reduce the impact force; when water overflows, the water overflows into the rotating fan blades, the rotating fan blades rotate reversely to drive the sealing cylinder to rotate reversely, and the sealing cylinder is meshed with the corresponding wide threads on the meshing ring to be matched and further sealed; after the water overflow is finished, the water flows downwards, the rotating fan blades rotate forwards, and the corresponding wide threads on the sealing cylinder and the meshing ring are disengaged.
