Les vannes de r\u00e9gulation de pression diff\u00e9rentielle \u2013 \u00e9galement commun\u00e9ment appel\u00e9es DPCV \u2013 sont install\u00e9es dans les syst\u00e8mes de chauffage ou de refroidissement pour contr\u00f4ler la pression du sous-circuit \u00e0 un maximum d\u00e9fini ou donn\u00e9.<\/p>\n\n\n\n
Extr\u00eamement efficace, le DPCV est r\u00e9gl\u00e9 sur une pression diff\u00e9rentielle maximale qui garantit que le d\u00e9bit ne peut pas d\u00e9passer un d\u00e9bit souhait\u00e9. Cela contribue donc \u00e0 r\u00e9duire la consommation d\u2019\u00e9nergie et le risque sonore et simplifie le processus de mise en service.<\/p>\n\n\n\n
La gamme ZECO DPCV comprend trois types diff\u00e9rents. Un type avec \u0394pC pr\u00e9d\u00e9fini (pression diff\u00e9rentielle dans le circuit), un type avec \u0394pC r\u00e9glable et enfin un type \u00e9tant une vanne d'\u00e9quilibrage dynamique combin\u00e9e et un DPCV r\u00e9glable. Ils offrent une gamme flexible r\u00e9pondant \u00e0 toute demande de syst\u00e8me.<\/p>\n\n\n

<\/figure>\n<\/div>\n\n\nPrincipe de fonctionnement de la vanne de r\u00e9gulation de pression diff\u00e9rentielle<\/h2>\n\n\n\n
La vanne de r\u00e9gulation de pression diff\u00e9rentielle n'a besoin d'aucune \u00e9nergie externe. Il peut s'ajuster automatiquement en s'appuyant sur le changement de pression du fluide r\u00e9gul\u00e9 lui-m\u00eame, \u00e9liminer automatiquement le changement de d\u00e9bit provoqu\u00e9 par la hauteur de pression r\u00e9siduelle et la fluctuation de pression du r\u00e9seau de canalisations, et maintenir constante la diff\u00e9rence de pression entre l'entr\u00e9e et la sortie de l'utilisateur. Il est particuli\u00e8rement adapt\u00e9 au comptage domestique ou au syst\u00e8me de contr\u00f4le automatique, ce qui favorise un fonctionnement stable du syst\u00e8me.<\/p>\n\n\n\n
La vanne de r\u00e9gulation de pression diff\u00e9rentielle est de structure \u00e0 double disque, avec une petite force d\u00e9s\u00e9quilibr\u00e9e et une structure compacte. Il est utilis\u00e9 dans le syst\u00e8me d\u2019eau de chauffage (climatisation) pour maintenir constante la pression diff\u00e9rentielle du syst\u00e8me contr\u00f4l\u00e9. Selon le principe de fonctionnement de la vanne de r\u00e9gulation de pression diff\u00e9rentielle, les utilisateurs qui installent la vanne de r\u00e9gulation de pression diff\u00e9rentielle n'installent pas le dispositif de contr\u00f4le automatique. Sous la diff\u00e9rence de pression de service minimale, lorsque le diam\u00e8tre du tuyau s\u00e9lectionn\u00e9 est trop grand et que la r\u00e9sistance est r\u00e9duite, le d\u00e9bit sera trop important, ce qui provoquera in\u00e9vitablement un d\u00e9s\u00e9quilibre hydraulique du r\u00e9seau externe et augmentera la consommation d'\u00e9nergie.<\/p>\n\n\n\n
La vanne de r\u00e9gulation de pression diff\u00e9rentielle est compos\u00e9e du corps de vanne, du couvercle de vanne, du ressort de noyau de vanne, du conduit de commande et du r\u00e9gulateur de pression.<\/p>\n\n\n\n
La vanne est install\u00e9e sur le tuyau de retour de la canalisation de chauffage et la chambre de travail de la vanne est reli\u00e9e au tuyau d'alimentation en eau via le tuyau de commande. \u00c9limine l'\u00e9cart de d\u00e9bit caus\u00e9 par la fluctuation de pression du r\u00e9seau externe. Lorsque la pression d'alimentation en eau P1 augmente, la diff\u00e9rence de pression d'alimentation en eau P1-P3 augmente. La membrane de d\u00e9tection de pression entra\u00eene le noyau de la vanne vers le bas pour fermer le petit port de la vanne, de sorte que P2 augmente, maintenant ainsi la constante P1-P2. Lorsque la pression d'alimentation en eau P1 diminue, la membrane de d\u00e9tection de pression entra\u00eene le noyau de la vanne \u00e0 monter et P2 diminue, de sorte que P1-P2 soit constant. Quelle que soit la fa\u00e7on dont la pression change dans le pipeline, la vanne d'\u00e9quilibrage de pression diff\u00e9rentielle dynamique peut maintenir la pression et le d\u00e9bit constants appliqu\u00e9s \u00e0 l'objet contr\u00f4l\u00e9.<\/p>\n\n\n\n
Principe de fonctionnement de la vanne de r\u00e9gulation de pression diff\u00e9rentielle auto-op\u00e9r\u00e9e<\/h2>\n\n\n\n
Une fois que le fluide de traitement est \u00e9trangl\u00e9 par la vanne, il entre dans l'\u00e9quipement contr\u00f4l\u00e9 et la pression diff\u00e9rentielle de l'\u00e9quipement contr\u00f4l\u00e9 est respectivement introduite dans les chambres \u00e0 membrane sup\u00e9rieure et inf\u00e9rieure de la vanne, g\u00e9n\u00e9rant une pouss\u00e9e dans les chambres \u00e0 membrane sup\u00e9rieure et inf\u00e9rieure et \u00e9quilibrant avec la force de r\u00e9action du ressort, de mani\u00e8re \u00e0 d\u00e9terminer la position relative du noyau de soupape et du si\u00e8ge de soupape, tandis que la position relative du noyau de soupape et du si\u00e8ge de soupape d\u00e9termine la taille de la valeur de pression diff\u00e9rentielle. Lorsque la pression diff\u00e9rentielle contr\u00f4l\u00e9e change, l'\u00e9quilibre de la force est d\u00e9truit, ce qui entra\u00eene le mouvement du noyau de vanne, et le mouvement du noyau de vanne modifie le coefficient de r\u00e9sistance de la vanne, c'est-\u00e0-dire que la valeur de pression diff\u00e9rentielle contr\u00f4l\u00e9e est contr\u00f4l\u00e9e comme la valeur r\u00e9gl\u00e9e. C'est le principe de fonctionnement de la vanne de r\u00e9gulation de pression diff\u00e9rentielle. Lorsque la valeur de r\u00e9glage de la pression diff\u00e9rentielle doit \u00eatre modifi\u00e9e, l'\u00e9crou de r\u00e9glage peut \u00eatre ajust\u00e9.<\/p>\n\n\n\n\n

In practice, the DPCV is used in several applications as will be further explained basically, its goal is to maintain a constant pressure difference across a certain part of the hydraulic network. Inside the DPCV, two cavities are separated by means of a membrane. One cavity is internally connected to the upstream side of the DPCV while the other one is connected to a remote location by means of a small capillary pipe. This way, the differential pressure across the membrane equals the pressure difference between the upstream measuring point and the DPCV. The resulting spindle travel depends on the force balance between the membrane and the spring.\r\n\r\n\r\n\r\n\r\n\r\n\u2022 \u0394P Control\r\n\r\n\r\n\r\n\r\n\r\nThe DPCV diaphragm will regulate to control \u0394pC (differential pressure across the circuit) depending on pressure impulse from the supply side and direct pressure from the return side.

How does a DPCV Work?<\/h2>\r\n\r\n\r\n\r\n\r\nA DPCV includes a diaphragm, a spring, and a capillary tube connecting the partner valve in the supply pipe and the DPCV valve in the return pipe to control the circuit pressure loss.\r\n\r\n\r\n\r\n\r\n\r\nThe differential pressure control valve (DPCV) is a special kind of control valve whose action is related to a measured pressure difference. In practice, the DPCV is used in several applications as will be further explained basically, its goal is to maintain a constant pressure difference across a certain part of the hydraulic network. Inside the DPCV, two cavities are separated by means of a membrane. One cavity is internally connected to the upstream side of the DPCV while the other one is connected to a remote location by means of a small capillary pipe. This way, the differential pressure across the membrane equals the pressure difference between the upstream measuring point and the DPCV. The resulting spindle travel depends on the force balance between the membrane and the spring.\r\n\r\n\r\n\r\n\r\n\r\n\u2022 \u0394P Control\r\n\r\n\r\n\r\n\r\n\r\nThe DPCV diaphragm will regulate to control \u0394pC (differential pressure across the circuit) depending on pressure impulse from the supply side and direct pressure from the return side. The spring force will equal the \u0394pC.\r\n\r\n\r\n\r\n\r\n\r\nIn all ZECO DPCVs, the diaphragm will be a rolling diaphragm which will result in a very compact valve design. Depending on the ZECO Differential Pressure Control Valve selected, \u0394pC may be fixed or externally adjustable.\r\n\r\n","parent":0,"count":12,"filter":"raw"}],"taxonomy_info":{"category":[{"value":2447,"label":"Balancing Valve"}],"post_tag":[{"value":3674,"label":"automatic balancing valve working principle"},{"value":3673,"label":"control valve working principle"},{"value":2517,"label":"differential pressure control valve"},{"value":3675,"label":"differential pressure control valve working principle"},{"value":2560,"label":"DPCV"}]},"yoast_head":"\n
