Abstract

Device for the hermetic assembly of flexible pressure pipes, perfected, of the type where the interconnection between the two pipes is obtained by means of a fitting that has a threaded tubing at one end threaded and opposite a smaller diameter, elongated nozzle with its external profile in saw tooth destined to receive by plug coupling to the section of the pipe, said fitting having a. Cylindrical section of greater thickness, in which an annular race of rectangular section is defined, joining in coaxiality on the flexible tube, after inserting in its bosom the mouthpiece, two equal semipiezas, like a half, cane, which has on its wall internal a serrated profile of reverse orientation, to that of the nozzle, being compressed against the section of the flexible pipe by contribution of a coaxial sleeve, which is superimposed, smooth inner wall whose mouth of greater pitch is close to the intermediate nut, of the coupling, essentially characterized in that both the said half-parts and the outer sleeve have a frustoconical section with a slightly accentuated inclination, the second having, together with its end portion, an annular groove or recess that corresponds positionally in its assembly situation, with the race practiced in the cylindrical section of the fitting, said groove having in its bottom, two through openings of sensitive length, affecting two to ones directly opposite arc and incorporating housed in its bottom or in the race of the fitting an elastic ring or staple circumferential, installed under pressure, part of whose longitudinal development affects the interior of the race of the fitting, or cited steps, immobilizing the sleeve that is linked to it can be separated from said position to disassemble the whole.
