Definitions

  • the claimed combined fittings relate to devices used in industry and housing for transporting liquid and gaseous media, including for water supply and heating of buildings and structures, production shops, etc.
  • Such fittings serve for the transition from plastic water supply and heating systems that use plastic pipes to metal pipelines (in particular, steel, copper) or for installation of threaded connection equipment in these systems.
  • the combined fitting is connected to the system with its plastic part through diffusion welding, and on the other hand, with metal pipelines by means of metal internal or external threads.
  • a combined fitting is made as follows: a metal embedded element, with structural elements made in advance (for example, with a thread), is laid in a mold. The mold is filled with high temperature plastic (e.g. for PPR 260 ° C). Thus, a fitting is obtained consisting of metal (for example, brass) and plastic parts connected inseparably. Metal and plastic have different thermal linear expansion due to which when the fitting cools, plastic delaminates from the metal.
  • the delamination that occurs during manufacturing and / or operation affects the appearance of the product, and, in addition, leads to unjustified hydraulic resistance of the system, a violation of the tightness of the fitting.
  • the technical result is to increase the reliability of the combined fitting with changes in temperature and mechanical loads during installation and operation by reducing the likelihood of delamination of the plastic from the metal during its manufacture and operation and, as a result, increasing the reliability of the systems transportation of liquids and gases.
  • the inventive utility model is illustrated in the graphic materials shown in figure 1 and figure 2.
  • Fig.1 shows a combination fitting, where the following notation:
  • Figure 2 shows a combined fitting, in the metal part of which grooves, grooves and recesses are formed, forming "plastic locks", where the following notation is accepted:
  • Achieving the claimed technical result is achieved by making grooves with a dovetail profile on the outside of the embedded part of the metal fitting of the combined fitting on its cylindrical part and / or by making a recess on the inside of the cylindrical part of the metallic part of the combined fitting and / or by performing on the inside of the metal part of the combined trapezoidal ring groove fitting.
  • the inverse taper angle Q of the grooves on the outside of the embedded metal part of the combined fitting on its cylindrical part with a dovetail profile in absolute value can vary from 1 ° to 89 °.
  • the specific value is selected depending on the stiffness of the plastic, the speed of its hardening.
  • the hardening rate and the value of the inverse taper angle Q are inversely proportional, the dependence between the plastic stiffness and the angle Q is of a similar nature.
  • annular groove on the inner side of the embedded metal part of the combined fitting, the recess on its inner side can also be performed with the opposite taper with a taper angle Q (this embodiment of the combined fitting is not shown in the drawing in Fig. 2).

Abstract

Ce modèle d'utilité concerne des dispositifs utilisés dans l'industrie et dans les immeubles d’habitation pour le transport de milieux liquides et gazeux, y compris pour l’alimentation en eau et le chauffage de bâtiments et de constructions, d'installations industrielles, etc. Le résultat technique obtenu grâce à ce modèle d’utilité consiste à augmenter la fiabilité du raccord combiné en cas de changements de température et sous l’effet de charges mécaniques lors de l’installation et du montage grâce à une moindre probabilité de décollement de plastique du métal lors de sa fabrication et son utilisation, ce qui assure une meilleure fiabilité des systèmes de transport de milieux liquides et gazeux. Le résultat technique est obtenu grâce au fait qu'au moins une des rainures côté externe de la partie cylindrique de la partie métallique du raccord combiné est conique et présente un profil en queue d'aronde et/ou un canal annulaire possédant une forme trapézoïdale est formé sur la surface interne de la partie métallique du raccord combiné et/ou qu’un logement est formé à la surface interne de la partie cylindrique de la partie métallique du raccord combiné.
