THERE IS DISCLOSED A BUOYANCY CONTROL GATE WHICH PERMITS THE FLOW OF WATER FROM ONE AREA TO ANOTHER AND PROHIBITS BACKFLOW. THE BUOYANCY CONTROL GATE IS ASSEMBLED TO INCLUDE A HOUSING (1) WITH AT LEAST ONE INLET CHANNEL (3) AND ONE OUTLET CHANNEL (2). AN ASSEMBLY OF ONE-WAY VALVE MEANS (4) IS ARRANGED WITHIN THE CAVITY OF THE HOUSING TO PROVIDE SUCH DESIRABLE FEATURE. THE ONE-WAY VALVE MEANS (4) INCLUDES A BUOYANT BODY (5) THAT IS ABLE TO MOVE UP AND DOWN FOR CLOSING OR OPENING THE OUTLET CHANNEL, RESPECTIVELY. THE BUOYANT BODY IS CONICALLY-SHAPED AND RETAINED IN POSITION WITHIN THE HOUSING BY A COMBINATION OF RETAINING SHAFT (6), A STOPPER PLATE (8), A SLEEVE (11) AND A JOINING PLATE (7). SUITABLE SEALING AND ABSORBING MEANS IS ALSO PROVIDED. THE PROPOSED BUOYANCY CONTROL GATE MAY SUITABLY BE USED FOR MANAGING AND CONTROLLING FLOODING DUE TO BACKFLOW OF WATER FROM WATERWAYS TO DRAINAGE, IRRIGATION SYSTEM OR THE LIKES.
