Abstract
Изобретение относитс к уплотнительной технике и может быть использовано дл уплотнени вращающихс валов насосов, компрессоров и турбин. Цель изобретени - повышение надежности за счет осевой разгрузки кольца. Уплотнение вращающегос вала содержит корпус 1, камеру 2 подвода затворной среды, установленное с дросселирующим зазором 3 относительно вала 4 плавающее кольцо 5, торцова упорна поверхность 6 которого сообщена с камерой 2 подвода затворной среды. Торцова поверхность 6 выполнена ступенчатой и разделена кольцевой проточкой 7 на два участка 8 и 9. При этом участок 9, близлежащий к валу, образует с корпусом дросселирующий зазор 10 к полости 11 низкого давлени , а кольцева проточка 7 соединена полуоткрытыми каналами 12 с камерой подвода затворной среды. 2 ил.The invention relates to a sealing technique and can be used to seal the rotating shafts of pumps, compressors and turbines. The purpose of the invention is to increase reliability due to axial unloading of the ring. The seal of the rotating shaft includes a housing 1, a chamber 2 for supplying a sealing medium, installed with a throttling gap 3 relative to the shaft 4, a floating ring 5, the end face 6 of which is connected to the chamber 2 for supplying a barrier medium. The end surface 6 is stepped and divided by an annular groove 7 into two sections 8 and 9. In this case, a section 9 adjacent to the shaft forms a throttling gap 10 to the low-pressure cavity 11 with the body, and the annular groove 7 is connected by half-open channels 12 to the gate supply chamber environment. 2 Il.
