Zusammenfassung:	FIELD: drop irrigation technique, in particular, irrigation of farm crops using flexible irrigation pipelines. ^ SUBSTANCE: irrigation pipeline has wall with water outlets spaced apart from one another by predetermined distance. Each water outlet is equipped with elastic valve made from pipeline material length formed as petal and positioned above water discharge opening. Thickness of petal is reducing from its base to end. Water discharge opening is formed in pipeline wall with inclination of 0.0014-0.0020 from inlet opening to discharge opening. Petal tip in its free state is raised above opening and is made rounded. Width of petal is set on the basis of ratio b=(0.2-0.3)D, where D is inner diameter of irrigation pipeline. ^ EFFECT: enhanced reliability in operation of valve and increased efficiency in regulated water feeding. ^ 2 cl, 2 dwg
