Que sont les vannes \u00e0 boisseau sph\u00e9rique ?<\/strong><\/h2>\n\n\n\n

Les vannes \u00e0 boisseau sph\u00e9rique sont des dispositifs m\u00e9caniques qui permettent de contr\u00f4ler, diriger, guider et moduler le flux de substances telles que les liquides, les gaz sous pression, etc. Il existe de nombreux types de vannes \u00e0 boisseau sph\u00e9rique qui contiennent diff\u00e9rents dispositifs pour diff\u00e9rents types d'utilisations.<\/p>\n\n\n\n

Les diff\u00e9rents types de vannes \u00e0 boisseau sph\u00e9rique peuvent \u00eatre class\u00e9s selon diff\u00e9rentes caract\u00e9ristiques telles que le nombre de ports, leur conception, le type de si\u00e8ge, l'acc\u00e8s \u00e0 la bille, l'assemblage du corps et leurs diam\u00e8tres de passage.<\/p>\n\n\n\n

Norme pour vanne \u00e0 boisseau sph\u00e9rique<\/strong><\/h2>\n\n\n\n

Les vannes \u00e0 boisseau sph\u00e9rique sont principalement con\u00e7ues pour \u00eatre conformes aux normes API 6D, API 6A et ANSI B16.34. L'API est utilis\u00e9 pour les sp\u00e9cifications de pipelines, l'API pour les \u00e9quipements de t\u00eate de puits et d'arbre de No\u00ebl, et l'ANSI pour les vannes, les soudures et les extr\u00e9mit\u00e9s \u00e0 brides. D'autres normes connexes telles que ANSI B16.5, ANSI B16.25 et ANSI B16.10 sont \u00e9galement utilis\u00e9es dans la conception des vannes \u00e0 boisseau sph\u00e9rique.<\/p>\n\n\n\n

Les vannes \u00e0 boisseau sph\u00e9rique sont \u00e9galement con\u00e7ues pour r\u00e9pondre aux exigences de s\u00e9curit\u00e9 incendie selon BS6755, API 607 et API 6FA. Les tests finaux sont effectu\u00e9s pour confirmer les exigences API 598, MSS SP 61, API 6D et API 6A.<\/p>\n\n\n\n

Types populaires de vannes \u00e0 boisseau sph\u00e9rique<\/strong><\/h2>\n\n\n\n

En fonction des applications de la vanne, les utilisateurs doivent d\u00e9terminer quel type de vanne \u00e0 boisseau sph\u00e9rique est le bon choix pour eux.<\/p>\n\n\n\n

1.<\/strong>   Vannes \u00e0 boisseau sph\u00e9rique \u00e0 passage en V<\/strong><\/h3>\n\n\n\n

Le V dans les vannes \u00e0 boisseau sph\u00e9rique \u00e0 passage en V indique la forme de la bille et la forme du si\u00e8ge. Cette vanne permet aux utilisateurs de mieux contr\u00f4ler la fermeture et l'ouverture.<\/p>\n\n\n\n

2.<\/strong>   Vannes \u00e0 boisseau sph\u00e9rique \u00e0 passage standard<\/strong><\/h3>\n\n\n\n

La vanne \u00e0 boisseau sph\u00e9rique \u00e0 passage standard a une bille et un passage beaucoup plus petits par rapport au passage int\u00e9gral. Elle est beaucoup moins ch\u00e8re mais elle entra\u00eene un d\u00e9bit l\u00e9g\u00e8rement restreint en raison de la taille du tuyau. Comme elles sont moins ch\u00e8res, elles ont la pression la plus \u00e9lev\u00e9e par rapport aux autres vannes. Tout comme les vannes \u00e0 passage int\u00e9gral, ces passages standard sont excellents pour les syst\u00e8mes avec un coefficient de d\u00e9bit \u00e9lev\u00e9.<\/p>\n\n\n\n

3.<\/strong>   Vannes \u00e0 boisseau sph\u00e9rique \u00e0 passage int\u00e9gral<\/strong><\/h3>\n\n\n\n

Ces vannes \u00e0 boisseau sph\u00e9rique \u00e0 passage int\u00e9gral sont plus ch\u00e8res que les autres types de vannes. Les vannes surdimensionn\u00e9es dans cette vanne \u00e0 passage int\u00e9gral r\u00e9duisent la perte de friction car le trou dans cette bille a la m\u00eame taille que la tuyauterie. Comme la vanne est plus grande, le d\u00e9bit n'est pas restreint dans la taille de la vanne \u00e0 boisseau sph\u00e9rique \u00e0 passage int\u00e9gral.<\/p>\n\n\n\n

4.<\/strong>   Vannes \u00e0 boisseau sph\u00e9rique multiport<\/strong><\/h3>\n\n\n\n

Les vannes \u00e0 boisseau sph\u00e9rique multiport comportent trois ou quatre voies avec un trou en forme de L ou de T au milieu de la vanne. Les vannes en T peuvent connecter toutes les paires de ports et les vannes en L peuvent connecter le port central aux ports lat\u00e9raux. L'entr\u00e9e de la vanne \u00e0 boisseau sph\u00e9rique multiport est en r\u00e9alit\u00e9 orthogonale au plan de la sortie. Les vannes \u00e0 boisseau sph\u00e9rique \u00e0 4 voies contiennent 2 ports en forme de L dans la bille multiport, appel\u00e9s port X.<\/p>\n\n\n\n

5.<\/strong>   Vanne \u00e0 boisseau sph\u00e9rique True Union<\/strong><\/h3>\n\n\n\n

La vanne \u00e0 boisseau sph\u00e9rique True Union contient une goupille qui aide \u00e0 maintenir la bille en place et emp\u00eache ses mouvements. Deux arbres sont plac\u00e9s aux extr\u00e9mit\u00e9s oppos\u00e9es dans la True Union, ce qui permet de supporter la bille segment\u00e9e. Cela permet \u00e9galement au syst\u00e8me de produire moins de friction entre les diff\u00e9rentes parties des vannes True Union.<\/p>","protected":false},"excerpt":{"rendered":"
