Abstract

Les procédés de production industrielle font appel à des éléments de réglage qui permettent leur optimisation, afin de maintenir un réglage précis du volume des fluides. Les soupapes sont des instruments majoritairement utilisés dans ce réglage. Les soupapes doivent être sélectionnées pour appliquer de manière efficace les instructions de commande émises depuis une salle de contrôle. Le dispositif interne des soupapes doit être conçu avec précision, de façon que, par l'intermédiaire des mouvements libres et articulés, le volume de fluide nécessaire pour le système de réglage soit obtenu. L'invention concerne la conception de pièces, qui une fois assemblées, donnent au dispositif des mouvements libres et articulés : longitudinal, circulaire, angulaire, de compression et d'expansion; l'utilisation de l'invention avec des soupapes permettant un réglage optimum des procédés. Il n'existe pas de soupapes dont les parties internes présentent les caractéristiques de l'invention, à savoir : A. - les deux parties internes (pointeau et siège) à mouvements libres et articulés. B. - Lubrification automatique. C- Zone de basse pression, pour réduire l'érosion. D. - Mouvement micrométrique, pour une haute précision. E. - Fermeture hermétique, en raison de la centralisation exacte des deux parties internes produite par les mouvements libres. F. - Pas de blocage en raison des mouvements libres et articulés. G. - Faible consommation de courant, en raison de la lubrification automatique.
