En tant que vannes les plus courantes dans les canalisations, les vannes papillon \u00e9lectriques sont utilis\u00e9es pour r\u00e9aliser la commutation du fluide et le contr\u00f4le du d\u00e9bit dans les syst\u00e8mes de canalisations. Il a \u00e9t\u00e9 largement utilis\u00e9 dans le p\u00e9trole, l\u2019industrie chimique, la m\u00e9tallurgie, l\u2019hydro\u00e9lectricit\u00e9 et bien d\u2019autres domaines. Parmi les vannes papillon \u00e9lectriques couramment utilis\u00e9es, elles sont principalement divis\u00e9es en vannes papillon \u00e0 pince \u00e9lectrique et en vannes papillon \u00e0 bride \u00e9lectrique, qui ont leurs propres caract\u00e9ristiques et performances diff\u00e9rentes et peuvent \u00eatre utilis\u00e9es dans diff\u00e9rentes industries. Pour ces deux types de vannes, en plus de la forme structurelle, si les m\u00eames param\u00e8tres sont utilis\u00e9s, la plus grande diff\u00e9rence est que le raccordement est diff\u00e9rent, c'est-\u00e0-dire que la forme d'installation doit d\u00e9pendre des conditions de travail !<\/p>\n\n\n\n\n\n
L'\u00e9paisseur de la vanne papillon \u00e9lectrique \u00e0 plaquette est plus fine que celle de la vanne papillon \u00e0 bride. Il n'y a pas de brides aux deux extr\u00e9mit\u00e9s du corps de vanne et seulement quelques trous de boulons de guidage. La vanne est reli\u00e9e \u00e0 la bride \u00e0 l'extr\u00e9mit\u00e9 du tuyau via un jeu de boulons\/\u00e9crous. C'est un endroit o\u00f9 l'espace est relativement \u00e9troit ou o\u00f9 les canalisations sont limit\u00e9es. Les avantages sont un d\u00e9montage facile, un faible co\u00fbt des vannes et un faible encombrement, mais l'inconv\u00e9nient est qu'il y a un probl\u00e8me avec la surface d'\u00e9tanch\u00e9it\u00e9, donc deux surfaces d'\u00e9tanch\u00e9it\u00e9 doivent \u00eatre retir\u00e9es.<\/p>\n\n\n\n
Le corps de la vanne papillon \u00e0 bride \u00e9lectrique a des brides aux deux extr\u00e9mit\u00e9s et est reli\u00e9 \u00e0 des brides de tuyau. Les performances d'\u00e9tanch\u00e9it\u00e9 sont plus fiables que celles de la vanne papillon \u00e0 plaquettes. Il est g\u00e9n\u00e9ralement utilis\u00e9 dans des zones de gros calibre ou \u00e0 haute pression, mais son co\u00fbt est relativement \u00e9lev\u00e9. Les vannes papillon \u00e0 clip \u00e9lectrique co\u00fbtent cher.<\/p>\n\n\n\n
Par exemple, les boulons des valves sont g\u00e9n\u00e9ralement tr\u00e8s longs. \u00c0 haute temp\u00e9rature, l'expansion des boulons peut entra\u00eener des fuites, ils ne conviennent donc pas aux grands diam\u00e8tres \u00e0 haute temp\u00e9rature. Par exemple, les vannes papillon \u00e0 pince ne peuvent pas \u00eatre utilis\u00e9es \u00e0 l'extr\u00e9mit\u00e9 du pipeline et l'aval doit \u00eatre d\u00e9mont\u00e9, car lorsque la bride aval est retir\u00e9e, la vanne \u00e0 pince tombera et doit \u00eatre tr\u00e8s courte. Bien que la vanne papillon \u00e0 bride ne pr\u00e9sente pas les probl\u00e8mes ci-dessus, le co\u00fbt sera relativement plus \u00e9lev\u00e9.

Corrosion Resistance<\/h3>\r\n\r\n\r\n\r\n\r\nWith Centerline Butterfly Valves only two parts of the valve come in contact with the medium. This means that neither the body nor mechanical parts such as the shaft are exposed to the corrosive environment.\r\n\r\n\r\n\r\n\r\n\r\nThe only two parts in contact with the medium are the body lining and the disc. These are available in a selection of materials so that a suitable corrosion-resistant combination can be chosen for most any application.\r\n\r\n\r\n\r\n\r\n
Bi-directional Shutoff<\/h3>\r\n\r\n\r\n\r\n\r\nCenterline Butterfly Valves are liquid and gas-tight in both flow directions. The disc presses with uniform compression into the elastic cartridge seat over the entire circumference of the valve.\r\n\r\n\r\n\r\n\r\n
Replaceable Seat<\/h3>\r\n\r\n\r\n\r\n\r\nThe replaceable seat consists of a reinforced backup ring, on which the elastomer seat material is vulcanized. When mounting the valve between the pipe flanges this stable seat cannot be deformed or displaced. The cartridge design also prevents deformation when the valve is cycled, such as stretching and bulging of the elastomer in front of the moving disc.\r\n\r\n\r\n\r\n\r\n\r\nThe fixed connection between the elastomer and the backup ring allows the use of the valve in a full vacuum and high flow velocities. The slightly protruding sealing lip of the seat also serves as the flange seal.\r\n\r\n\r\n\r\n\r\n
