It is commonly used in medical applications to prevent contamination due to backflow. One end of the valve is stretched over the outlet of a supply line, conforming itself to the shape of the line, usually round. The other end, the duckbill, retains its natural flattened shape. When a fluid is pumped through the supply line and therefore the duckbill, the flattened end opens to permit the pressurized fluid to pass. When pressure is removed, however, the duckbill end returns to its flattened shape, preventing backflow. The duckbill valve is similar in function to the mitral valve in the heart. See also Heimlich valve. A trifold form of this valve, known as a joker valve, is used in one popular marine toilet.〔http://www.jabscoshop.com/spare-parts/default.aspx?code=29090-2000〕 == References == 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Duckbill valve」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
