摘要

FIELD: drop irrigation technique, in particular, irrigation of farm crops using flexible irrigation pipelines. ^ SUBSTANCE: valve-water outlet is positioned within wall of irrigation pipeline equipped with water discharge opening, lock head provided above water discharge opening and made in the form of two spherical segments. Lock head rests upon inner wall of pipeline by means of elastoplastic curved legs joined to outer edge of lock valve and inner wall of pipeline along arc of the circle. Lock head is connected to outer restricting plate through rod consisting of cylindrical and conical parts. Conical part is made in the form of paraboloid of rotation. ^ EFFECT: enhanced reliability in operation of valve and increased efficiency in regulated water feeding. ^ 2 cl, 2 dwg
