Abstract

Шиберная задвижка содержит два противолежащих корпусных элемента, затвор, основные уплотняющие втулки и вторичный уплотняющий элемент. Основные уплотняющие втулки расположены в каждом из корпусных элементов. Затвор выполнен с возможностью скольжения через поперечную затворную камеру при соединении корпусных элементов. Вторичный уплотняющий элемент зафиксирован между корпусными элементами и содержит по меньшей мере один проход или отверстие, выполненное с возможностью подачи смазочной жидкости к затвору через по меньшей мере один из корпусных элементов и вспомогательный уплотняющий элемент.
