Description
Устройство работает следующим образом .The device works as follows.
Изолирующий материал 8 закачиваетс между лидирующей 2 и покрывной 1 пробками через отверсти 5 в покрывной пробке. Под воздействием сжатого воздуха система из двух пробок приходит в движение. Изолирующий материал 8 поступает через входные 4 и выходные 5 отверсти покрывной пробки 1 на покрывную манжету 7, посред- ством которой на внутреннюю поверхность трубопровода наноситс равномерный слой толщиной свыше 0,5 мм. Гибкий край покрывной манжеты 7 не пропускает при этом воздушный поток вперед покрывной пробки 1.Insulating material 8 is pumped between the leading 2 and covering 1 plugs through openings 5 in the covering plug. Under the influence of compressed air, the system of two plugs is set in motion. The insulating material 8 enters through the inlet 4 and the outlet 5 of the opening of the plug 1 to the covering cuff 7, with which a uniform layer over 0.5 mm thick is applied to the inner surface of the pipeline. The flexible edge of the cover cuff 7 does not allow air flow forward of the cover plug 1.
Остаток изол ционного материала в конце участка трубопровода будет вытесн тьс через входные 4 и выходные 5 ртвер- сти в лидирующей пробке 2 и далее через выходной патрубок в конце трубы в сборную емкость. The remainder of the insulating material at the end of the pipeline section will be forced out through the inlet 4 and outlet 5 hoses in the lead plug 2 and then through the outlet at the end of the pipe into the collection container.
