Abstract

Un dispositif anti-cavitation compact de conditionnement, un type de pagaie utilisé conjointement avec des soupapes de commande traditionnelles, installées à une entrée de soupape pour dissiper lénergie du fluide en limitant la pression et la vitesse du fluide liquide pour procurer une pression différentielle normale à travers la soupape et éliminer ultérieurement le problème de cavitation des soupapes. Le dispositif comprend deux plaques à orifices perforés de conditionnement découlement et de pression intégrales, ayant différentes dimensions de trou sans trou central, composées dacier inoxydable pour une insertion en amont de la bride de la soupape de commande traditionnelle, ou le système de tuyauterie utilisé avec la face soulevée des soupapes normales ou des brides dassemblage de type de bague, faisant face à une condition de traitement grave de fluide dans laquelle la plaque de conditionnement de première pression absorbe une pression différentielle prédéterminée, la seconde plaque avec des perforations de plus petite taille agit pour dissiper lénergie de la vitesse du fluide et offrir une condition de traitement normale en amont de la soupape pour atteindre un indice de cavitation plus élevé, et éliminer finalement le problème de cavitation, dérosion, dans des soupapes de liquide et de bruit généré dans des soupapes à gaz, le dispositif conçu pour chaque condition de procédé de soupape.
