Abstract (en)
[origin: WO9745600A1] A liquid drainage system for a hard-top surface (1), such as at an airport, harbour area and the like, comprises a gutter (3), which is provided in the said surface (1) and is connected to a sink hole (6, 7), from which the liquid can be drained via a sewer (8). A ball valve (16) is provided in the sink hole (6, 7), which ball valve comprises a valve as well as a ball body which floats in water and sinks in a lighter liquid, such as kerosine, so that the valve interacts in a sealing manner with an associated valve seat, which ball valve is located between the gutter (3) and the sewer (8).
