Fonctionnement

Construction

Le concept de la vanne Unique Mixproof est basé sur une série de composants élémentaires, dont le corps de vanne, le bouchon, l'actionneur, les options de nettoyage et les accessoires qui favorisent une large gamme d'applications. En utilisant ces composants, vous pouvez construire une vanne Unique Mixproof pour répondre exactement à vos exigences de processus.

Pour faciliter l'entretien, la vanne Unique Mixproof possède également des orifices de détection des fuites qui préviennent l'usure ou l'endommagement des joints toriques statiques. Les opérateurs peuvent inspecter visuellement la vanne à tout moment sans avoir à la démonter.

Principe de fonctionnement

La vanne Unique Mixproof Alfa Laval est une vanne normalement fermée qui est commandée à distance par de l'air comprimé.

Pour séparer les deux liquides, la vanne est équipée de deux joints de clapet indépendants. L'espace entre les deux joints forme une chambre de fuite atmosphérique. Dans les rares cas de fuite accidentelle de produit, le produit s'écoule dans la chambre de fuite et est évacué par la sortie de fuite.

Lorsque la vanne est ouverte, la chambre de fuite est fermée. Le produit peut alors s’écouler d’une ligne à l’autre sans déversement. La vanne peut être facilement nettoyée et protégée contre les coups de bélier en fonction des exigences spécifiques liées au processus et de la configuration de la vanne. (Il n'y a pas de déversement de produit pendant le fonctionnement de la vanne)

SpiralClean system

Alfa Laval offers its external connected CIP system "SpiralClean". This system ensures hygienic operation in demanding applications where cleaning of the Unique Mixproof by seat lift and seat push function is not sufficient. The SpiralClean system can be added to clean the upper and lower plugs and to rinse the leakage chamber of the valve. Using less cleaning fluid, utilities and time, SpiralClean cleans more thoroughly and efficiently than conventional externally connected CIP devices.

Another big benefit: SpiralClean enables the Unique mixproof valve to operate under aseptic-like conditions, creating a steam barrier to the atmosphere upon applying steam to the CIP pipes.unique-mixproof-spiral-clean-640x360.jpg
