Vue d'ensemble des vannes de r\u00e9gulation \u00e0 auto-actionnement :<\/p>\n

 <\/p>\n

La vanne de r\u00e9gulation \u00e0 auto-actionnement ZZYP est principalement compos\u00e9e d'une vanne de r\u00e9gulation, d'un actionneur et d'un ressort pour le r\u00e9glage de la pression. Elle est adapt\u00e9e aux liquides, gaz et vapeur non corrosifs. Contr\u00f4le de pression avant la vanne dans la conduite du syst\u00e8me (lorsque la pression avant la vanne augmente, la vanne de r\u00e9gulation s'ouvre) ou apr\u00e8s la vanne (lorsque la pression apr\u00e8s la vanne augmente, la vanne de r\u00e9gulation s'ouvre). Largement utilis\u00e9e dans le p\u00e9trole, l'industrie chimique, l'\u00e9nergie \u00e9lectrique, la m\u00e9tallurgie, la m\u00e9decine, l'alimentation, le textile, la machinerie, le CVC. Les types d'action incluent la r\u00e9gulation de pression apr\u00e8s la vanne de r\u00e9duction de pression (type B) et la r\u00e9gulation de pression avant la vanne de d\u00e9charge de pression (type K).<\/p>\n

Caract\u00e9ristiques des vannes de r\u00e9gulation de pression \u00e0 auto-actionnement :<\/p>\n

 <\/p>\n

Compar\u00e9e \u00e0 la vanne de r\u00e9gulation manuelle, la vanne de r\u00e9gulation de pression \u00e0 auto-actionnement pr\u00e9sente l'avantage d'un r\u00e9glage automatique ; compar\u00e9e \u00e0 la vanne de r\u00e9gulation \u00e9lectrique, son avantage est qu'elle ne n\u00e9cessite pas d'alimentation externe. La vanne de r\u00e9gulation \u00e0 auto-actionnement utilise la pression et la temp\u00e9rature du fluide qui la traverse comme source d'\u00e9nergie pour actionner la vanne automatiquement, sans n\u00e9cessiter d'alimentation externe ni d'instruments secondaires.<\/p>\n

 <\/p>\n

Fonction des vannes de r\u00e9gulation de pression \u00e0 auto-actionnement :<\/p>\n

 <\/p>\n

Toutes les vannes de r\u00e9gulation \u00e0 auto-actionnement utilisent le signal de retour (pression, pression diff\u00e9rentielle, temp\u00e9rature) \u00e0 la sortie de la vanne pour le transmettre \u00e0 l'actionneur via le tuyau de signal afin de modifier l'ouverture de la vanne et d'atteindre l'objectif de contr\u00f4le de la pression, du d\u00e9bit et de la temp\u00e9rature. Dans le syst\u00e8me de circulation d'eau ferm\u00e9 (tel que le syst\u00e8me de chauffage \u00e0 eau chaude, le syst\u00e8me d'eau glac\u00e9e de climatisation), l'utilisation correcte de cette vanne peut facilement r\u00e9aliser la distribution du d\u00e9bit du syst\u00e8me ; elle peut r\u00e9aliser l'\u00e9quilibre dynamique du syst\u00e8me ; elle peut grandement simplifier le travail de d\u00e9bogage du syst\u00e8me ; elle peut stabiliser l'\u00e9tat de fonctionnement de la pompe, etc.<\/p>\n
