vanne \u00e0 bille flottante<\/a> et une vanne \u00e0 bille fixe basse temp\u00e9rature. Elle est utilis\u00e9e pour couper ou allumer le fluide \u00e0 basse temp\u00e9rature dont la temp\u00e9rature minimale dans la canalisation n'est pas inf\u00e9rieure \u00e0 moins 196 degr\u00e9s Celsius.<\/p>\nAfin d'\u00e9viter la d\u00e9faillance du joint de la garniture de la tige dans des conditions de basse temp\u00e9rature, le robinet \u00e0 bille basse temp\u00e9rature adopte une structure \u00e0 long col.<\/p>\n
Le si\u00e8ge est con\u00e7u avec une fonction de d\u00e9charge automatique de pression pour arr\u00eater le fluide dans la vanne. L'augmentation anormale de la pression due \u00e0 l'augmentation de la temp\u00e9rature exige un contr\u00f4le strict de la composition chimique du mat\u00e9riau et des propri\u00e9t\u00e9s m\u00e9caniques telles que la r\u00e9sistance aux chocs \u00e0 basse temp\u00e9rature.<\/p>\n
Caract\u00e9ristiques :<\/strong>
\n1. Ce robinet est un robinet \u00e0 boisseau sph\u00e9rique flottant \u00e0 passage int\u00e9gral, avec une structure compacte, une belle apparence et un faible coefficient de r\u00e9sistance \u00e0 l'\u00e9coulement.
\n2. La surface d'\u00e9tanch\u00e9it\u00e9 est en plastique fluor\u00e9, les mat\u00e9riaux des paires d'\u00e9tanch\u00e9it\u00e9 sont appari\u00e9s de mani\u00e8re raisonnable et la dur\u00e9e de vie est longue.
\n3. La bille et le si\u00e8ge de soupape en PTFE sont herm\u00e9tiquement scell\u00e9s et combin\u00e9s avec la fonction de fuite z\u00e9ro, et peuvent automatiquement compenser l'erreur caus\u00e9e par l'usure en utilisant la d\u00e9formation plastique, et atteindre une bonne performance d'\u00e9tanch\u00e9it\u00e9.
\n4. Diverses normes de brides de tuyaux et divers types de surfaces d'\u00e9tanch\u00e9it\u00e9 de brides peuvent \u00eatre s\u00e9lectionn\u00e9s. Des m\u00e9thodes d'entra\u00eenement manuelles, par turbine, \u00e9lectriques, pneumatiques, hydrauliques et autres sont disponibles pour r\u00e9pondre aux diff\u00e9rents besoins des utilisateurs.<\/p>\nUtilisation :<\/strong>
\nLa vanne \u00e0 bille cryog\u00e9nique est principalement utilis\u00e9e dans les \u00e9quipements chimiques tels que l'\u00e9thyl\u00e8ne et le gaz naturel liqu\u00e9fi\u00e9.<\/p>\nVous voudrez peut-\u00eatre aussi lire :
