摘要

The invention relates to dismantleable connectors for simplified assembly of pipelines, pipeline elements or various components of a network, without having any recoil necessary for the interlocking or passage of a sealing gasket. The connector consists of three pieces with a bought-out sealing gasket (O-ring or 4-lobe seal). The pieces, base 1 and screw 3, are made from metal or plastic. They are assembled to the other elements of the network by welding, brazing, bonding or threading. The assembly nut 2 is provided with a conical taper 4 coming at the end of clamping, to form a housing of triangular cross-section with two chamfers 5 and 6 made on each of the end parts 1 and 3. The standard bought-out sealing ring 7 will be placed in this housing. IMAGE
