Abstract

Raccordo per il bloccaggio assiale a tenuta di tubazioni liscie ad organi di attacco filettati comprendente una ghiera (1) in cui all'estremità di detta ghiera (1) opposta a quella filettata, è presente una riduzione di diametro costituente un collare (5) internamente sagomato a superficie conica, il quale è posto in impegno assiale con una corrispondente superficie conica (7c) di detto mandrino deformabìle (7) disposto in appoggio su detto manicotto di tenuta (8), detto manicotto di tenuta (8) presentando esternamente un ingrossamento radiale (8a) sagomato in modo da trovare alloggiamento stabile entro una corrispondente cavità anulare (1b) ricavata internamente a detta ghiera; in conseguenza del serraggio di detta ghiera il manicotto di tenuta (8), viene deformato tra tubo da collegare, mandrino, superficie interna della ghiera ed estremità dell'organo di attacco, realizzando così la tenuta sia idraulica sia meccanica tra tubo (6) e attacco filettato (4).Fitting for the axial sealing of smooth pipes with threaded attachment members comprising a ring nut (1) in which at the end of said ring nut (1) opposite the threaded one, there is a reduction in diameter constituting a collar (5) internally shaped with a conical surface, which is placed in axial engagement with a corresponding conical surface (7c) of said deformable mandrel (7) arranged resting on said sealing sleeve (8), said sealing sleeve (8) externally showing an enlargement radial (8a) shaped so as to find stable housing within a corresponding annular cavity (1b) formed inside said ring nut; as a result of the tightening of said ring nut the sealing sleeve (8) is deformed between the tube to be connected, the mandrel, the internal surface of the ring nut and the end of the attachment member, thus creating both the hydraulic and mechanical seal between the tube (6) and threaded connection (4).
