CARACT\u00c9RISTIQUES TECHNIQUES<\/h2>\n

1) Un r\u00e9ducteur de pression proportionnel est une vanne automatique qui r\u00e9duit la pression d'entr\u00e9e \u00e0 la pression de sortie dans un rapport fixe gr\u00e2ce \u00e0 un r\u00e9glage m\u00e9canique proportionnel.
\n2. sa fonction principale est de stabiliser la pression de sortie et de garantir que le pipeline ou l'\u00e9quipement en aval fonctionne dans une plage de pression s\u00fbre.
\n3. \u00e9quilibre dynamique de la pression sans contr\u00f4le externe
\n4. d\u00e9tection de la pression\uff1aLa pression \u00e0 la sortie est transmise \u00e0 la chambre sup\u00e9rieure du diaphragme\/piston par l'interm\u00e9diaire de la conduite de retour.
\n5. la membrane est soumise \u00e0 l'effet combin\u00e9 de la pression de sortie et de la force du ressort.
\n6.\u00e9quilibre dynamique\uff1aLorsque la pression de sortie augmente : la membrane se d\u00e9place vers le haut sous l'effet de la pression, poussant le disque de la vanne \u00e0 se d\u00e9placer dans le sens de la fermeture, r\u00e9duisant la section d'\u00e9coulement du fluide, et la pression de sortie diminue.
\n7. lorsque la pression de sortie diminue : la force du ressort pousse le diaphragme vers le bas, le disque de la vanne s'ouvre pour augmenter la surface d'\u00e9coulement, et la pression de sortie augmente.
\n8. caract\u00e9ristiques proportionnelles : la pression de sortie est toujours ajust\u00e9e en fonction du rapport pr\u00e9d\u00e9fini (par exemple 1\/2 de la pression d'entr\u00e9e), quelles que soient les variations de d\u00e9bit.
\n9. stabilisation automatique de la pression\uff1aLa position du disque de la vanne est automatiquement ajust\u00e9e en fonction des fluctuations de la pression d'entr\u00e9e afin de maintenir la pression de sortie stable.<\/p>\n

DOSSIER<\/h2>\n

1) Pression constante proportionnelle : la pression de sortie est dans un rapport fixe avec la pression d'entr\u00e9e, ce qui convient aux sc\u00e9narios avec de grandes fluctuations de la pression d'entr\u00e9e.
\n2. structure simple\uff1aAucune \u00e9nergie externe ou dispositif de contr\u00f4le complexe, reposant sur un r\u00e9glage purement m\u00e9canique, d'une grande fiabilit\u00e9.
\n3. conception sans entretien\uff1aAucun composant \u00e9lectronique, forte r\u00e9sistance \u00e0 la pollution, convient aux milieux dont la qualit\u00e9 de l'eau est m\u00e9diocre (tels que les syst\u00e8mes d'eau d'incendie).
\n4. large adaptabilit\u00e9\uff1aSupport des fluides liquides et gazeux, rapport commun de 1,5:1 \u00e0 4:1, pression de travail maximale jusqu'\u00e0 PN25.<\/p>\n
