Abstract

Узел герметизации для применения в областях с высоким давлением, в которых предусматривается электрическая изоляция между соединенными элементами, а также повышенное сопротивление утечке среды во время воспламенения. Уплотнение, выдерживающее высокое давление, выполняется с использованием металлической пластины, к которой с одной или с обеих сторон прикрепляется электрически изолирующий материал. Изоляция обеспечивается за счет диэлектрического уплотнительного элемента, например, такого как политетрафторэтиленовое (PTFE) кольцо. Фланцы сопряжения могут соединяться друг с другом шпильками с установленной между ними прокладкой. В случае воспламенения может вырабатываться тепло, которое при достижении достаточной высокой температуры приведет к сгоранию изолирующего материала и кольца PTFE. В узлах различных вариантов осуществления предусматривается резервная прокладка и ограничитель сжатия, которые, соответственно, не дают текучей среде вытекать из места соединения и удерживают нагрузку на шпильки.
