Two=part rotary pipe coupling - has pipe coaxial to coupling part bearings, forming annular space with coupling parts

摘要

The pipe coupling comprises two tubular sections, rotatable about their longitudinal axis and forming a pressure-tight joint. Each section is fitted with a pipe connecting union. A pipe (4) extends through both tubular sections (1,2), coaxial to their bearings (1). An annular space (5) is formed between the pipe and the sections. The pipe ends turn in the sections and form seals with the connecting unions (15,16). Each tubular section has a further pipe union (17,18), leading into the annular space. The first connecting unions (15,16) may be coaxial to the inner pipe, while the second ones (17,18) may be inclined to this pipe axis.
