Description

  

  Joint à plomb coulé pour conduites d'eau, gaz, air, etc.    L'invention a pour objet un joint étanche  destiné à réunir les éléments tubulaires des  conduites d'eau, de gaz, d'air ou autres fluides  sous pression.  



  Jusqu'ici, les joints à plomb utilisés dans  ce but nécessitaient des matages très oné  reux et donnaient lieu à des fuites surtout  dès que la pression intérieure tendait à s'é  lever dans la conduite.  



  Le joint qui fait l'objet de l'invention est  caractérisé par le fait que le plomb qui y  est coulé est accroché intérieurement et exté  rieurement et ainsi rendu solidaire des em  bouts mâle et femelle à raccorder, au moyen  de rainures formées sur les parois opposées  de ces embouts.  



  La figure unique du dessin annexé montre,  à titre d'exemple, la coupe     d'une-forme    d'exé  cution du joint suivant l'invention.  



  Sur ce dessin, a désigne le plomb coulé  formant joint; b désigne l'embout femelle à  raccorder, dans la paroi intérieure duquel est  ménagée une rainure circulaire     c,    en forme  de queue d'aronde.     d    désigne l'embout mâle,  qui présente extérieurement des rainures e,  qui, concurremment avec la rainure en queue    d'aronde c, servent à ancrer la masse de  plomb<I>a</I> formant joint; l'élément mâle<I>d</I> est  terminé par une bride f servant à retenir  un enroulement de ficelle goudronnée y, sur  lequel prend appui le joint en plomb a.  



  L'ensemble du joint ainsi établi est d'au  tant plus étanche que la pression est plus  élevée- il supporte facilement des pressions  intérieures de 25 kg. Ce joint procure en  outre une économie très sensible de plomb.  Enfin, il supprime la     main-d'oeuvre    nécessaire  au matage.



  Cast lead seal for water, gas, air pipes, etc. The object of the invention is a tight seal intended to join the tubular elements of the pipes for water, gas, air or other fluids under pressure.



  Until now, lead seals used for this purpose required very expensive matting and gave rise to leaks, especially as soon as the internal pressure tended to rise in the pipe.



  The joint which is the subject of the invention is characterized by the fact that the lead which is poured therein is hooked inside and outside and thus made integral with the male and female ends to be connected, by means of grooves formed on the walls opposite of these end caps.



  The single figure of the attached drawing shows, by way of example, the section of an embodiment of the seal according to the invention.



  In this drawing, a denotes the cast lead forming a joint; b designates the female end to be connected, in the inner wall of which is formed a circular groove c, in the form of a dovetail. d designates the male end, which has grooves e on the outside, which, together with the dovetail groove c, serve to anchor the mass of lead <I> a </I> forming a joint; the male element <I> d </I> is terminated by a flange f serving to retain a winding of tarred twine y, on which the lead seal a bears.



  The entire seal thus established is the more tight the higher the pressure - it easily withstands internal pressures of 25 kg. This seal also provides a very significant saving in lead. Finally, it removes the labor required for matting.
