kupplungsanordnung for plastic piping with small diameter and small diameter plastic piping

摘要

it is a kupplungsanordnung for plastic piping (p) of small diameter is proposed, which as a coupling for a pipe of small diameter is used.the clutch includes: a hauptku00f6rper (1), a chamber (3, - 1) of smaller diameter in continuity with a kommunikationsbohrung (4), a cylindrical anschluu00dfwand (2) at the upper end of the hauptku00f6rpers (1) is defined, and a chamber (3) of larger diameter, the hinte the chamber (3) smaller diameter is formed, is arranged; and a sleeve (5).the inward sloping walls (1) which, for each in the form of a sperrklinke (5-1) is formed, and the integral with, or separately from an outer periphery of the kupplungshauptku00f6rpers (1) are formed, and the inside inclined walls (1, 1) of the sleeve (5) is in contact with a ring shaped curved wall (p ') of the kunststoffrohres (p).there is also a du00fcnnwandiges metal pipe (m), an annular convex wall (m ') is in at least the verbindungsende of kunststoffrohres (p) used in the metal tube (m) as verstu00e4rkungsglied for plastic piping (p) is used.the plastic piping (p) can be an annular convex wall (p), aggravated by preu00dfumformen (coiling) of the metallrohres (m) in an axial direction together with the metal tube (m) is established. the present invention can ensure the clutch connection of the hose to be small diameter with the...
