Les vannes \u00e0 boule \u00e0 trois voies sont utilis\u00e9es dans les applications comportant plusieurs tuyaux ou pour d\u00e9vier le fluide dans deux directions diff\u00e9rentes. En fonction du sens d’\u00e9coulement, les trois orifices sont attribu\u00e9s comme une sortie et deux entr\u00e9es ou une entr\u00e9e et deux sorties. <\/strong><\/p>\n

Les vannes \u00e0 boisseau sph\u00e9rique \u00e0 trois voies<\/strong> ont trois orifices et peuvent \u00eatre actionn\u00e9es manuellement ou automatis\u00e9es \u00e0 l’aide d’un actionneur \u00e9lectrique ou pneumatique. L’orifice traversant le boisseau sph\u00e9rique existe en deux variantes : orifice en \u00ab L \u00bb et orifice en \u00ab T \u00bb. Les vannes \u00e0 trois voies peuvent :
\u2022 Couper ou fermer le d\u00e9bit
\u2022 Modifier le d\u00e9bit entre deux sources diff\u00e9rentes
\u2022 Combiner le d\u00e9bit de deux sources diff\u00e9rentes
\u2022 Alterner le d\u00e9bit entre deux destinations diff\u00e9rentes
\u2022 D\u00e9tourner le d\u00e9bit provenant d’une source vers une autre destination
\u2022 Diviser le d\u00e9bit provenant d’une source entre deux destinations de sortie <\/p>\n

Types de vannes \u00e0 boisseau sph\u00e9rique \u00e0 3 voies : en L et en T. <\/strong><\/h3>\n

En L, vous pouvez envoyer le flux dans un sens ou dans l’autre, ou le fermer compl\u00e8tement. La diff\u00e9rence avec les vannes \u00e0 3 voies en T est qu’elles ne peuvent pas fermer le passage du fluide. Elles peuvent \u00e9galement m\u00e9langer les flux provenant des deux c\u00f4t\u00e9s. Les lettres \u00ab T \u00bb et \u00ab L \u00bb font r\u00e9f\u00e9rence \u00e0 la forme de l’ouverture de la sph\u00e8re.
Une vanne \u00e0 boisseau sph\u00e9rique \u00e0 3 voies fonctionne en tournant la poign\u00e9e, qui fait tourner le boisseau \u00e0 l’int\u00e9rieur du corps de la vanne, afin d’aligner les canaux de coupe du boisseau avec les entr\u00e9es et les sorties de la vanne. La d\u00e9coupe en forme de \u00ab L \u00bb envoie le fluide \u00e0 90 degr\u00e9s d’un port \u00e0 l’autre. La d\u00e9coupe en forme de \u00ab T \u00bb, en plus de pouvoir \u00eatre envoy\u00e9e d’un port \u00e0 l’autre, peut \u00e9galement \u00eatre tourn\u00e9e de mani\u00e8re \u00e0 ce que les trois ports se m\u00e9langent.
Pour fermer tous les flux dans une vanne \u00e0 3 voies \u00e0 orifice en T, une vanne s\u00e9par\u00e9e doit \u00eatre ajout\u00e9e aux deux branches oppos\u00e9es. Pour fermer le flux, les deux vannes doivent \u00eatre ferm\u00e9es et la bille de la vanne \u00e0 3 voies doit \u00eatre tourn\u00e9e vers l’arri\u00e8re de la vanne. <\/p>\n

Les vannes en L peuvent uniquement diriger le flux \u00e0 90 degr\u00e9s ou le fermer compl\u00e8tement.
Les vannes en T peuvent diriger le flux comme souhait\u00e9, mais ne peuvent pas le fermer compl\u00e8tement.<\/p>\n
