УПЛОТНЯЮЩЕЕ КОЛЬЦО ДЛЯ ТРУБНОГО СОЕДИНЕНИЯ С ВСТАВНЫМИ МУФТАМИ

摘要

A tension ring fits into an inwardly open cavity in the sealing ring. which is mirror-symmetrical and has two facing lip-seals (1,2). The opposite-facing lip-seals pointing inwards at a slant to the plane of symmetry (3) of the sealing ring form a U-shaped recess for the tension ring. The lip-seals can be deflected towards the plane of symmetry by inserting the sealing ring with inserted tension ring into the annular beading on the sleeve end of the pipe-end. Between the rim sections and the tension ring is formed a cavity holding a lubricant.
