Abstract

L'orifice pour la ventilation d'eaux usées contaminées selon la présente invention est un orifice qui est installé au niveau d'un emplacement nécessitant de l'air ou près de celui-ci pour le maintien efficace d'un équilibre de pression à l'intérieur de la conduite sans endommager ni modifier le joint étanche à l'eau du siphon en raison de fluctuations rapides, et qui régule l'écoulement des eaux usées contaminées afin d'empêcher tout retour d'eau. L'orifice comprend : un corps principal d'orifice qui fournit l'air nécessaire en cas de pression négative à l'intérieur de la conduite ; un bouchon supérieur accouplé à la partie supérieure du corps principal d'orifice afin de fournir un espace dans lequel le corps principal d'orifice peut fonctionner, et qui fonctionne comme un passage pour l'air arrivant de l'extérieur et qui empêche l'exposition à l'extérieur de la partie supérieure du corps principal d'orifice de ventilation ; et un adaptateur accouplé à la partie inférieure du corps principal d'orifice qui forme une liaison à une conduite d'eaux usées contaminées existante et qui fournit un passage à travers lequel l'air entrant par l'intermédiaire du corps principal d'orifice peut entrer dans la conduite d'eaux usées contaminées. Le corps principal d'orifice comprend : un corps inférieur par l'intermédiaire duquel l'air est admis et qui forme un passage à travers lequel l'air qui est admis entre dans la conduite ; une partie d'admission d'air formée au niveau de la partie externe supérieure du corps inférieur et par l'intermédiaire de laquelle entre l'air ; une partie de blocage des impuretés formée au niveau de la partie intérieure supérieure du corps inférieur et formant un passage à travers lequel l'air qui entre par l'intermédiaire de la partie d'admission d'air s'écoule vers la partie inférieure du corps inférieur et qui empêche les impuretés de s'écouler en direction du bouchon supérieur en cas de pression positive à l'intérieur de la conduite ; et une lame d'air installée au niveau de la partie supérieure de l'ouverture d'admission d'air pour empêcher la fuite des eaux usées contaminées à l'intérieur de la conduite en cas de pression positive à l'intérieur de la conduite, et pour permettre l'admission de l'air en cas de pression négative. Une goupille de fixation en trois points est formée au niveau de l'ouverture d'admission d'air afin d'empêcher le gauchissement ou le retrait de la lame d'air et de maintenir la lame d'air de manière à bloquer l'entrée d'air même lorsque l'orifice est installé de travers. L'orifice pour la ventilation des eaux usées contaminées selon la présente invention remplace les conduites de ventilation pour divers(es) cuvettes, toilettes, éviers et autres installations sanitaires afin de permettre la réduction des coûts relatifs aux matériaux, à la main d'œuvre et à l'installation, ne doit pas nécessairement être installé verticalement pour résoudre les différentes restrictions imposées en matière de conception et d'installation, et permet d'empêcher facilement tout retour des eaux usées et des eaux usées contaminées grâce à une fourniture d'air constante.
