SLIDE RING FOR CORRUGATED WATER CARRYING OR DRAIN PIPE Russian patent published in 2008 - IPC E03F3/04 

FIELD: constructionc, water supply.

SUBSTANCE: invention pertains to the field of construction of joined corrugated pipes. The slide ring for corrugated pipes is made from flexible material, has in its cross section, a V-shape, which converges to the longitudinal axis of symmetry of the ring. The periphery end part is formed from connection of arcs of circle quadrants, which run from the lateral surface of the sealing surface to the outer sealing perimeter, and a semicircle arc of smaller diameter, coupled with an arc of inverse curvature and smaller radius with a parallel longitudinal axis of symmetry of the ring through the rear part of the V-shaped body. On parts of the lateral surface of the ring, in the cross section of the V-shape, there are ring shaped projections, located concentrically relative to the longitudinal axis of symmetry of the ring, the same height as the bearing surface, and located on both sides of the ring in pairs, at equal displacements from the longitudinal axis of symmetry of the ring. The technical outcome is the increased tightness of joints.

EFFECT: increased tightness of joining pipes due to improvements on the slide ring.
