(54) ПРОБКОВЫЙ КРАН(54) CRANKSHAFT
(57) Изобретение относитс к трубопроводной арматуре, в частности к арматуре оросительных систем в шахтах. Цель изобретени - уменьшение гидравлического сопротивлени за счет сдува вихревой зоны. При открытии крана поворотом пробки 4 основной поток рабочей жидкости проходит через вырез 11, завихр сь после мостика жесткости 12, а часть жидкости - через выполненный в мостике жесткости 12 канал 13, уменьша вихревую зону за указанным мостиком жесткости 12. 2 ил,(57) The invention relates to pipe fittings, in particular to fittings for irrigation systems in mines. The purpose of the invention is to reduce the hydraulic resistance due to the blow-off of the vortex zone. When opening the valve by turning the plug 4, the main flow of the working fluid passes through the cutout 11, swirl after the stiffness bridge 12, and part of the fluid goes through channel 13, which is made in the stiffness bridge 12, reducing the swirl zone beyond the stiffening bridge 12. 2,
