Definitions

  • the invention relates to a pipe connector for liquid and gas pipes according to the preamble of claim 1.
  • a predecessor of such a pipe connector is the subject of German patent 10 2007 006 816 of the applicant.
  • Klemmringschraubharmen with rubber-elastic seals and metallic spacers and compression joints in which the tube is pressed by plastic deformation of a compression sleeve against the main body of the pipe joint, and sliding sleeve joints in which an additional metal sleeve is placed on the pipe end and on the base body of the compound.
  • These are used in both drinking water and heating and cooling installations as well as gas installations and are manufactured in the form of coupling, T-piece, angle, elbow, distributor parts and fittings.
  • the sliding sleeve consists of two parts, namely an outer sleeve made of metal and an inner sleeve made of plastic.
  • the invention has for its object to provide a pipe joint, which is inexpensive to manufacture and easy to assemble and in particular is stable and tight even at higher temperatures and pressures.
  • a pipe joint with the features of claim 1 which provides a spring-shaped pipe backup.
  • This spring-shaped pipe lock is pushed onto the pipe to be connected like a classic sliding sleeve.
  • the main body of the pipe joint may have a Einrastrille, engages in one end of the spring-sliding sleeve. In this embodiment, both are pressed by axial displacement of the spring-sliding sleeve frictionally into each other and thus hooked.
  • the cross-sectional profile of the detent groove may be semi-circular, conical, rectangular or otherwise shaped to receive the end of the spring and secure it to the body.
  • the spring-sliding sleeve according to the invention consists of metal, preferably made of stainless steel.
  • the spring sliding sleeve may also consist of another material, which has the required properties for the function of securing the tube on the body. Compared with the predecessor model explained above, the spring-sliding sleeve connects due to their features of claim 1 elasticity and stability in one part.
  • One embodiment of the pipe joint has a cap which bears against one end of the spring-sliding sleeve.
  • This cap provides a better contact surface for the previously used assembly tool, which is designed for plastic-metal sliding sleeves. It acts as an adapter for the assembly tool and thus ensures compatibility with the older system and can be made of plastic or metal.
  • Another embodiment has an additional sleeve in the interior of the spring-sliding sleeve.
  • This sleeve is preferably made of plastic.
  • the spring-sliding sleeve is supplemented in this way with the inner sleeve, which has a Einrast leopard with the features of DE 10 2007 006 816.
  • the inner sleeve version offers the possibility of combining older fittings with the new spring technology. It thus represents an intermediate stage and consequently makes possible a gradual transition from the predecessor system to the spring-sliding sleeve system presented here.
  • a sealing ring made of elastic material can be used between the sliding sleeve and the base body to prevent penetration of the liquid or gaseous medium.
  • a sealing ring made of elastic material can be used between the sliding sleeve and the base body.
  • this compound proved to be extremely stable even under high thermal and mechanical loads. This is due to the mechanical property of the spring-sliding sleeve, which can expand and contract with temperature fluctuations, without significantly changing the pressure on the underlying pipe end. Thus, the tube end is frictionally enclosed under all temperature conditions and preserved from sliding off the body.
  • the spring-shaped fuse offers instead of a classic sliding sleeve also better grip with axial and radial pressure changes of the connected pipe, especially in the execution of the connection with a Einrastrille on the body in which the spring hooks and prevents them from slipping mechanically. In classical systems, this sliding occurs mostly after some time with frequent and large temperature fluctuations as a result of the linear expansion of the tube and because of different expansion coefficients of different materials of the sliding sleeves.
  • the spring-sliding sleeve is compared to the previous model very easy and inexpensive to produce.
  • the assembly effort is low with this system.
  • the installation is hardly different from that of the previously common sliding sleeve systems.
  • the body remains unchanged in this type of pipe joint compared to the previous model (DE 10 2007 006 816).
  • the pipe connection portion of the body may have on its Rohranliege Chemistry
  • Sge leopardpro fil in which the teeth may be formed in different sizes and shapes. These points can be aligned left, right or in both directions and can have a triangular, V, M or U profile in cross section.
  • FIG. 1 shows a longitudinal sectional view through a pipe connection of a base body in engagement with a plastic or plastic-metal-plastic composite pipe, on which a spring-sliding sleeve is pushed and the connection is thus tight and secured,
  • FIG. 2 shows a variant of Figure 1, in which the base body has a Einrastrille, in which one end of the spring-sliding sleeve is engaged and this additionally secures on the pipe end,
  • FIG. 3 shows a further variant of the invention, in which the spring-sliding sleeve has an adapter cap, which is designed so that it bears against the corresponding assembly tool, which can be used appropriately,
  • Figure 4 shows a further variant of the invention, in which the spring-sliding sleeve inside a sleeve having a Einrast leopard which hooks in axial displacement with the base body
  • Figure 5 shows a further variant of the invention, in which the inner sleeve has at its end an additional peripheral edge, which prevents slipping of the spring sleeve of the inner sleeve.
  • the pipe connection shown in Figure 1 consists of a base body 1 and a pipe connection portion la of the fitting and a spring-sliding sleeve 2 for fixing the end of a hose or pipe 3. This is pushed onto the pipe connection portion la and is located between the base body 1 and the spring Slide sleeve 2 frictionally and tightly engaged.
  • the pipe connection portion la of the fitting has an outer surface with a sawtooth profile lb. On this the previously expanded end of the pipe to be connected 3 is pushed.
  • the base body 1 While in the embodiment of Figure 1, the base body 1 has no additional assurance for the spring-sliding sleeve 2, it is externally provided in Figure 2 with a circumferential, barb-shaped Einrast leopard ld, which prevents slipping of the spring sliding sleeve 2.
  • the spring-sliding sleeve 2 is additionally equipped with a cap 5, which is needed in some cases as an adapter for a mounting tool.
  • the inner sleeve 6 at its end a circumferential projection 6a, which prevents the sliding of the spring-sliding sleeve 2 of the inner sleeve 6.
