| 摘要 |
The present invention relates to a pipe coupling, designed as a thread jointing having a male part (1), a female part (7) and a jointing ring (11), disposed therebetween, which parts are coaxially disposed and penetrated by the coaxially disposed pipe (10), which is to be connected, said jointing ring comprising a front portion (12) with a front conical rotation-symmetrical surface (12a), which abuts an also conical internal surface (4a) in said male part, a rear rigid portion (20) in contact with said female portion as well as a deformation-portion (15), which is positioned between said front and said rear portions and designed to be able to be deformed when subjected to forces in the axial direction. Said deformation-portion (15) is designed as a comparatively thin wall (21), which connects the external periphery of said front portion (at 18) with the internal periphery of said rear portion (at 17). |
