Abstract

Przedmiotem wzoru użytkowego jest złącze (1) przewodów rurowych. Rozwiązanie ma zastosowanie przy szczelnym łączeniu przewodów rurowych, w szczególności dla przesyłu gazów pod wysokim ciśnieniem, np. gazu ziemnego. Złącze (1) przewodów rurowych, w którym odcinek (7) rury (2) stalowej, którego końcówka (3) jest wyprofilowana, ma nasadzoną nakrętkę (8), a rura (2) jest przyłączona do sąsiadującego z nią dalszego elementu (9) linii przesyłowej, znajdującego się w sekwencji za rurą (2) stalową. Element (9) linii przesyłowej ma na swym zakończeniu (10) gwint łączący (11) zewnętrzny. Nasadzana na odcinek (7) rury (2) stalowej nakrętka (8) ma od strony elementu (9) przesyłowego wewnętrzny gwint główny (15) krótszy niż szerokość nakrętki (8), przy czym wyprofilowana końcówka (3) odcinka (7) rury (2) stalowej jest zaciągana nakrętką (8) do wnętrza (12) elementu (9) linii przesyłowej mając z nim pierścieniową linię styku. Odcinek (7) rury (2) stalowej z wyprofilowaną końcówką (3) ma gwint pomocniczy pierwszy (16) po swej zewnętrznej stronie, przy czym gwint pomocniczy pierwszy (16) jest oddalony od wewnętrznego skraju wyprofilowania (17) i od skraju rury (2) nie więcej niż na odległość równą szerokości nakrętki (8), która prócz gwintu głównego (15) ma także wewnętrzny gwint pomocniczy drugi (18), zgodny kierunkiem i skokiem z gwintem pomocniczym pierwszym (16), jednak przeciwny kierunkiem z gwintem łączącym (11) i gwintem głównym (15), a gwint pomocniczy drugi (18) i gwint główny (15) są w nakrętce (8) rozdzielone.The subject of the utility model is the pipe connector (1). The solution is used for tightly connecting pipes, in particular for the transmission of gases under high pressure, e.g. natural gas. The pipe connector (1) in which the section (7) of the steel pipe (2), whose end (3) is profiled, has a nut (8), and the pipe (2) is connected to the adjacent distal element (9) transmission line located in the sequence behind the steel pipe (2). The transmission line element (9) has at its end (10) a connecting thread (11) external. The nut (8) put on the section (7) of the steel pipe (2) has an internal main thread (15) shorter than the width of the nut (8) from the transmission element (9) side, the profiled end (3) of the section (7) of the pipe (8) 2) steel is pulled with a nut (8) inside the (12) element (9) of the transmission line having with it an annular contact line. The section (7) of the steel pipe (2) with the profiled end (3) has a first auxiliary thread (16) on its outer side, the first auxiliary thread (16) being away from the inner edge of the profiling (17) and from the edge of the pipe (2) ) not more than a distance equal to the width of the nut (8), which, apart from the main thread (15), also has an internal second auxiliary thread (18), matching the direction and pitch of the first auxiliary thread (16), but the opposite direction with the connecting thread (11) ) and main thread (15), and the second auxiliary thread (18) and main thread (15) are separated in the nut (8).
