<p>The sealing ring for wave plastic pipe equipped external waves in which the symmetric sealing ring is created for sealing contra second pipe (14) in which is mounted wave plastic pipe with two side relieving elements (3, 4) outgoing from basic corps (1) for reaching sides of the wives of the wave pipe (13); whereby the basic corps (1) in unloaded condition of the sealing ring is possible to enter into down of the wave of the wave pipe (13) without tension; whereby the side relieving elements (3, 4) outgoing from basic cords (1) contains inside flaps (10, 11), which can reach on the adjacent top of the wave pipe (13); and whereby central sealing (2) during the disengagement of the wave pipe (13) into second pipe (14) is avoided aside and it press adjacent the side relieving element (3) against the direction of the inserting.. The side relieving elements (3, 4) have the erase flaps (5, 6) destined to the symmetry level of the sealing ring from basic element (1) outgoing the central sealing (2) in the form disc ring is overhung outside via the erase flaps (5, 6) and relieving elements (3, 4) show external cuts in form V for creating the relieving flaps (7, 8).</p> |
