Abstract

Изобретение относитс  к нефтеи нефтепродуктопроводному транспорту. Целью изобретени   вл етс  повышение герметичнос.ти перекрыти  трубопровода . На корпусе 1 размецено кольцевое уплотнение в виде разрезного упругого кожуха 5, внутри которого размещен поропласт 6, пропитанный в зким пластичным составом. При ст жке болтами 10 корпуса 1 и нажимной втулки 3 происходит вытеснение пластичного состава из кожуха 5 в зазор между кольцевым уплотнением и трубопроводом 11. Устройство обеспечивает надежную герметизацию по имеющей значительные неровности внутренней поверхности трубопровода, что снижает опасность возникновени  взрывов и пожаров при ремонте трубопроводов. 2 ил.This invention relates to a petroleum and petroleum product pipeline transport. The aim of the invention is to improve the hermetic sealing of the pipeline. On the housing 1 there is an annular seal in the form of a split elastic casing 5, inside of which there is a foam plastic 6 impregnated with a viscous plastic composition. When bolting 10 of the housing 1 and the pressure sleeve 3, the plastic composition is displaced from the casing 5 into the gap between the annular seal and the pipe 11. The device provides reliable sealing along the internal surface of the pipeline with significant irregularities, which reduces the risk of pipelines. 2 Il.
