发明名称 MECHANICAL VALVE FOR A WATERLESS URINAL
摘要 Described is a duckbill valve assembly for connecting with a waterless urinal. The assembly includes a sleeve for containing a duckbill valve therein. The duckbill valve includes a trough with two substantially parallel sheets forming a sealing area. At least one of the substantially parallel sheets includes a side pleat. When the parallel sheets separate as the valve opens, the side pleat expands, increasing the opening cross-sectional area over that afforded by the parallel sheets alone.
