Dans les canalisations industrielles et civiles modernes, le choix des vannes est crucial, car il affecte directement l'efficacit\u00e9 op\u00e9rationnelle et la stabilit\u00e9 de l'ensemble du syst\u00e8me. Les deux types de vannes les plus courants sont\u00a0: vannes \u00e0 boisseau sph\u00e9rique<\/a> et vannes papillon<\/a> sont souvent compar\u00e9s par les utilisateurs.\u00a0<\/p>\r\n\r\n\r\n\r\n

Quelles sont les diff\u00e9rences entre une vanne \u00e0 boisseau sph\u00e9rique et une vanne papillon\u00a0? Comment choisir l'une ou l'autre en fonction des conditions de travail\u00a0? Cet article vous propose une analyse compl\u00e8te pour vous aider \u00e0 choisir le type de vanne le plus adapt\u00e9.<\/p>\r\n\r\n\r\n\r\n

Que sont les vannes \u00e0 boisseau sph\u00e9rique et les vannes papillon ?<\/h2>\r\n\r\n\r\n\r\n

Robinet \u00e0 boisseau sph\u00e9rique<\/h3>\r\n\r\n\r\n\r\n

Une vanne \u00e0 boisseau sph\u00e9rique contr\u00f4le le d\u00e9bit d'un fluide par la rotation de la bille \u00e0 l'int\u00e9rieur du corps. L'int\u00e9rieur est constitu\u00e9 d'une sph\u00e8re perc\u00e9e d'un trou. Lorsque le trou de la sph\u00e8re est orient\u00e9 dans la m\u00eame direction que la canalisation, le fluide peut circuler sans \u00e0-coups\u00a0; lorsque la bille est tourn\u00e9e de 90\u00a0degr\u00e9s, le canal de la vanne est compl\u00e8tement ferm\u00e9 et le fluide ne peut pas passer, ce qui permet une ouverture et une fermeture rapides.\u00a0<\/p>\r\n\r\n\r\n\r\n

La structure de la vanne \u00e0 boisseau sph\u00e9rique est divis\u00e9e en type \u00e0 boisseau sph\u00e9rique flottant et type \u00e0 boisseau sph\u00e9rique fixe.\u00a0<\/p>\r\n\r\n\r\n\r\n

Type de boule flottante :<\/strong> Il s'appuie sur la pression du milieu pour pousser la bille contre la bague d'\u00e9tanch\u00e9it\u00e9 afin de former un joint.\u00a0<\/p>\r\n\r\n\r\n\r\n

Type de boule fixe : <\/strong>Ce type de vanne \u00e0 boisseau sph\u00e9rique fixe la bille \u00e0 travers les arbres sup\u00e9rieur et inf\u00e9rieur, ce qui est plus adapt\u00e9 aux syst\u00e8mes de grand diam\u00e8tre ou \u00e0 haute pression.\u00a0<\/p>\r\n\r\n\r\n\r\n

De plus, les vannes \u00e0 boisseau sph\u00e9rique sont divis\u00e9es en types \u00e0 diam\u00e8tre complet et \u00e0 diam\u00e8tre r\u00e9duit.<\/p>\r\n\r\n\r\n\r\n

Type \u00e0 diam\u00e8tre complet :<\/strong> Le canal \u00e0 l'int\u00e9rieur de cette vanne \u00e0 boisseau sph\u00e9rique est adapt\u00e9 au diam\u00e8tre de la canalisation, de sorte que le fluide dans la canalisation rencontre moins de r\u00e9sistance lors du passage.<\/p>\r\n\r\n\r\n\r\n

Type \u00e0 diam\u00e8tre r\u00e9duit :<\/strong> Comme son nom l'indique, le canal interne de la vanne \u00e0 boisseau sph\u00e9rique de diam\u00e8tre r\u00e9duit est adapt\u00e9 au diam\u00e8tre de la canalisation, principalement pour des raisons d'\u00e9conomie d'espace et de co\u00fbt. Avec une telle structure, le fluide dans la canalisation rencontre une certaine r\u00e9sistance lors de son passage.<\/p>\r\n\r\n\r\n\r\n

vanne papillon<\/h3>\r\n\r\n\r\n\r\n

Le composant d'ouverture et de fermeture de la vanne papillon est une plaque papillon en forme de disque, qui peut ouvrir et fermer le milieu de la canalisation en tournant \u00e0 90 degr\u00e9s.\u00a0<\/p>\r\n\r\n\r\n\r\n

Selon leurs diff\u00e9rentes structures de conception, les vannes papillon peuvent \u00eatre class\u00e9es en vannes papillon \u00e0 axe central, vannes papillon \u00e0 double excentration et vannes papillon \u00e0 triple excentration. Parmi ces derni\u00e8res, les vannes papillon \u00e0 triple excentration offrent les meilleures performances d'\u00e9tanch\u00e9it\u00e9 et sont adapt\u00e9es aux conditions de travail difficiles.\u00a0<\/p>\r\n\r\n\r\n\r\n

La principale caract\u00e9ristique de la vanne papillon est sa structure compacte, sa petite taille et son poids l\u00e9ger, ce qui la rend particuli\u00e8rement adapt\u00e9e aux syst\u00e8mes de gros calibre et basse pression. La rotation de la plaque papillon au milieu de la canalisation pour contr\u00f4ler l'angle d'ouverture permet une certaine r\u00e9gulation du d\u00e9bit.\u00a0<\/p>\r\n\r\n\r\n\r\n

Bien que la vanne papillon soit l\u00e9g\u00e8rement inf\u00e9rieure \u00e0 la vanne \u00e0 boisseau sph\u00e9rique en termes de performances d'\u00e9tanch\u00e9it\u00e9, elle est facile \u00e0 installer et peu co\u00fbteuse, ce qui en fait un \u00e9quipement indispensable et important dans les infrastructures urbaines.<\/p>\r\n\r\n\r\n\r\n

Vanne \u00e0 boisseau sph\u00e9rique ou vanne papillon<\/h2>\r\n\r\n\r\n\r\n

En pratique, quelles sont les principales diff\u00e9rences entre les vannes \u00e0 boisseau sph\u00e9rique et les vannes papillon\u00a0? Voici une comparaison d\u00e9taill\u00e9e de quatre dimensions cl\u00e9s\u00a0:<\/p>\r\n\r\n\r\n\r\n

1. M\u00e9thode d'ouverture et de fermeture<\/h3>\r\n\r\n\r\n\r\n

Vannes \u00e0 boisseau sph\u00e9rique<\/strong> La vanne peut \u00eatre ouverte ou ferm\u00e9e rapidement et compl\u00e8tement en tournant la bille dans le corps. Son fonctionnement est intuitif et ne n\u00e9cessite aucun r\u00e9glage complexe. Elle convient aux syst\u00e8mes n\u00e9cessitant peu de variations de d\u00e9bit.\u00a0<\/p>\r\n\r\n\r\n\r\n

La vanne papillon<\/strong> Il peut \u00eatre partiellement ouvert ou partiellement ferm\u00e9 en ajustant l'angle de la plaque papillon. Il est adapt\u00e9 aux situations o\u00f9 une certaine pr\u00e9cision de contr\u00f4le du d\u00e9bit dans la canalisation est requise, comme les syst\u00e8mes CVC, le traitement des eaux, etc.<\/p>\r\n\r\n\r\n\r\n

2. Performances d'\u00e9tanch\u00e9it\u00e9<\/h3>\r\n\r\n\r\n\r\n

En termes d'\u00e9tanch\u00e9it\u00e9, les vannes \u00e0 boisseau sph\u00e9rique sont g\u00e9n\u00e9ralement sup\u00e9rieures aux vannes papillon. Leur structure m\u00e9tallique et souple permet d'\u00e9viter toute fuite sous haute pression et convient aux environnements exigeant une \u00e9tanch\u00e9it\u00e9 parfaite, comme dans les industries chimiques, p\u00e9troli\u00e8res et gazi\u00e8res.\u00a0<\/p>\r\n\r\n\r\n\r\n

En ce qui concerne les vannes papillon, en raison de la m\u00e9thode de contact entre la plaque papillon et la bague d'\u00e9tanch\u00e9it\u00e9, les performances d'\u00e9tanch\u00e9it\u00e9 de certains mod\u00e8les sont l\u00e9g\u00e8rement inf\u00e9rieures dans les syst\u00e8mes \u00e0 haute pression ou lors du transport de milieux granulaires, mais elles peuvent toujours r\u00e9pondre aux besoins de la plupart des syst\u00e8mes de traitement de l'eau et civils.\u00a0<\/p>\r\n\r\n\r\n\r\n

3. Diff\u00e9rences d'espace d'installation et de co\u00fbt<\/h3>\r\n\r\n\r\n\r\n

En raison de leur structure complexe, de leur taille relativement grande et de leur co\u00fbt \u00e9lev\u00e9, les vannes \u00e0 boisseau sph\u00e9rique ont des besoins d'espace plus \u00e9lev\u00e9s lors de l'installation et n\u00e9cessitent plus d'espace d'installation.<\/p>\r\n\r\n\r\n\r\n

Les vannes papillon sont largement appr\u00e9ci\u00e9es pour leur l\u00e9g\u00e8ret\u00e9 et leur facilit\u00e9 d'installation, notamment sur les canalisations de grand diam\u00e8tre. Elles permettent non seulement de gagner de la place, mais aussi de r\u00e9duire consid\u00e9rablement les co\u00fbts du syst\u00e8me.<\/p>\r\n\r\n\r\n\r\n

4. Conditions applicables aux supports et au syst\u00e8me<\/h3>\r\n\r\n\r\n\r\n

Les vannes \u00e0 boisseau sph\u00e9rique conviennent au transport de liquides ou de milieux gazeux \u00e0 haute temp\u00e9rature, haute pression, volatils ou corrosifs, et sont largement utilis\u00e9es dans la p\u00e9trochimie, l'\u00e9nergie \u00e9lectrique, la fabrication du papier et d'autres domaines.<\/p>\r\n\r\n\r\n\r\n

Les vannes papillon conviennent aux sc\u00e9narios conventionnels tels que l'approvisionnement en eau municipal, les syst\u00e8mes de climatisation, le traitement des eaux us\u00e9es et les syst\u00e8mes de protection contre les incendies, en particulier dans les syst\u00e8mes basse pression de grand diam\u00e8tre qui n\u00e9cessitent un fonctionnement facile.<\/p>\r\n\r\n\r\n\r\n

La s\u00e9lection du type de vanne appropri\u00e9 n\u00e9cessite un jugement complet bas\u00e9 sur plusieurs facteurs tels que les conditions de travail r\u00e9elles, le type de fluide, les exigences du syst\u00e8me, etc.<\/p>\r\n\r\n\r\n\r\n
