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

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

Cet article vous aidera \u00e0 conna\u00eetre les composants des vannes \u00e0 boisseau sph\u00e9rique. Les vannes \u00e0 boisseau sph\u00e9rique sont construites avec de nombreux \u00e9l\u00e9ments qui sont les suivants :<\/p>\n\n\n\n

1.<\/strong>   Corps de vanne<\/strong><\/h3>\n\n\n\n

C'est la partie principale de la vanne. Elle contient tous les composants pour les commandes de fermeture et d'ouverture.<\/p>\n\n\n\n

2.<\/strong>   Sph\u00e8re rotative<\/strong><\/h3>\n\n\n\n

Cette sph\u00e8re est con\u00e7ue avec un al\u00e9sage central qui facilite l'\u00e9coulement du fluide. La direction de la sph\u00e8re est contr\u00f4l\u00e9e en tournant la tige.<\/p>\n\n\n\n

3.<\/strong>   Tige<\/strong><\/h3>\n\n\n\n

Elle relie la sph\u00e8re \u00e0 l'ext\u00e9rieur et au m\u00e9canisme de commande. Par exemple, dans une vanne \u00e0 boisseau sph\u00e9rique manuelle, la tige est connect\u00e9e au levier ou \u00e0 la poign\u00e9e.<\/p>\n\n\n\n

4.<\/strong>   Si\u00e8ges<\/strong><\/h3>\n\n\n\n

Ce sont les disques situ\u00e9s entre la sph\u00e8re et le corps. Les si\u00e8ges assurent l'\u00e9tanch\u00e9it\u00e9 entre les deux. Ils supportent \u00e9galement la sph\u00e8re.<\/p>\n\n\n\n

5.<\/strong>   Source d'\u00e9nergie<\/strong><\/h3>\n\n\n\n

La tige de la vanne \u00e0 boisseau sph\u00e9rique est tourn\u00e9e en utilisant des sources d'\u00e9nergie actionn\u00e9es manuellement ou automatiquement. Les actionneurs manuels comprennent les poign\u00e9es et les leviers. Ils sont contr\u00f4l\u00e9s par un op\u00e9rateur. Des sources d'\u00e9nergie automatis\u00e9es telles que les actionneurs pneumatiques, \u00e9lectriques et hydrauliques sont \u00e9galement disponibles.<\/p>\n\n\n\n

6.<\/strong>   Garniture<\/strong><\/h3>\n\n\n\n

C'est le joint autour de la tige qui aide \u00e0 emp\u00eacher le fluide de s'\u00e9chapper.<\/p>\n\n\n\n

7.<\/strong>   Bo\u00eete de garniture<\/strong><\/h3>\n\n\n\n

Le chapeau est la partie du corps. Il contient la garniture et la tige.<\/p>\n\n\n\n

Conceptions de boisseau sph\u00e9rique<\/strong><\/h2>\n\n\n\n

Il existe deux principaux types de conception de boisseau sph\u00e9rique : \u00e0 tourillon et flottant. Le flottant est la conception la plus courante de la vanne \u00e0 boisseau sph\u00e9rique, tandis que les tourillons sont plus chers. Les boisseaux flottants sont support\u00e9s par des si\u00e8ges en cuvette pour cr\u00e9er une bonne \u00e9tanch\u00e9it\u00e9 entre les corps. Les boisseaux \u00e0 tourillon fonctionnent avec les boisseaux flottants. Seuls les si\u00e8ges sont \u00e0 ressort et le boisseau tourne uniquement sur son axe. Le couple de man\u0153uvre est tr\u00e8s faible pour les vannes \u00e0 tourillon.  <\/p>\n\n\n\n

Applications des vannes \u00e0 boisseau sph\u00e9rique<\/strong><\/h2>\n\n\n\n

Conclusion<\/strong><\/h2>\n\n\n\n

Une vanne est un dispositif qui permet de r\u00e9guler et de diriger le flux d'un liquide en ouvrant, fermant et obstruant un ou plusieurs passages. Les vannes \u00e0 boisseau sph\u00e9rique sont un type de vannes quart de tour qui permettent de contr\u00f4ler le d\u00e9bit. Elles constituent une alternative plus importante \u00e0 des vannes similaires telles que les vannes \u00e0 opercule et les vannes papillon. En fonction des applications de la vanne, les utilisateurs doivent d\u00e9terminer le type de vanne \u00e0 boisseau sph\u00e9rique qui leur convient le mieux.<\/p>","protected":false},"excerpt":{"rendered":"
