FIELD: packaging industry. ^ SUBSTANCE: proposed gate comprises split ring consisting of sliding sheets, each suspended on to outer ring of floating cover by means of two-link hinge mechanisms and spring-loaded towards reservoir wall, and membrane jointed, on one side, to split ring, and, on the other side, jointed to floating cover outer ring. Two-link hinge mechanisms are arranged in horizontal plane. Hinge axles are inclined to floating cover outer ring at 5Ç30 to vertical line, hinge mechanism ends can move in horizontal plane from split ring side in reservoir radius direction. ^ EFFECT: simplified design and higher reliability. ^ 3 cl, 4 dwg |
