Abstract

В уплотнительном устройстве (1), предназначенном для герметизации сквозного отверстия для электрода, нагнетательной средой, которая создает давление для прижимания механических уплотнений к узлу стержневого электрода, является инертный газ, такой, например, как азот. Средства прижимания составного уплотнительного кольца (6) к узлу (4) стержневого электрода содержат кольцевую газораспределительную камеру (8), окружающую уплотнительное кольцо (6), первый канал (9), выполненный с обеспечением прохождения потока инертного газа на участке между эластичной трубкой (14) и газораспределительной камерой (8), кольцевую канавку (10), расположенную на уплотнительной поверхности (7) уплотнительного кольца (6), и второй канал (11), который расположен в уплотнительном кольце (6) и выполнен с обеспечением поступления газа из газораспределительной камеры (8) в канавку (10) для нагнетания газа между уплотнительной поверхностью (7) и узлом (4) стержневого электрода.
