Description de la vanne papillon pneumatique\u00a0:<\/h2>\n

La vanne papillon pneumatique ZECO, principalement utilis\u00e9e dans le pipeline en tant que fonction de troncature, consiste \u00e0 utiliser des dispositifs pneumatiques pour entra\u00eener l'action d'ouverture et de fermeture du disque papillon rotatif de la tige de la vanne afin d'obtenir l'effet de troncature ou d'\u00e9coulement moyen ouvert. \u00c0 l'heure actuelle, les vannes papillon basse pression de grand diam\u00e8tre ou de diam\u00e8tre moyen sont davantage utilis\u00e9es dans les canalisations. Vanne papillon pneumatique essentiellement canalis\u00e9e \u00e0 haute altitude, \u00e0 travers l'ouverture et la fermeture de l'\u00e9lectrovanne de contr\u00f4le de la vanne, mais a \u00e9galement pour effet de r\u00e9guler le d\u00e9bit du fluide, la r\u00e9sistance du fluide de la vanne papillon est petite, grand diam\u00e8tre et le diam\u00e8tre de la vanne papillon pneumatique ouvre tout la zone de circulation efficace est grande, car les raisons d'ouverture et de fermeture du dispositif pneumatique sont tr\u00e8s rapides et \u00e9conomiques. \u00c9tant donn\u00e9 que le disque des deux c\u00f4t\u00e9s de la tige de valve re\u00e7oit une force presque \u00e9gale du fluide, mais produit un couple dans des directions oppos\u00e9es, le couple d'ouverture et de fermeture est donc faible et facile \u00e0 ouvrir. Sous basse pression, la vanne papillon peut \u00e9galement obtenir une bonne \u00e9tanch\u00e9it\u00e9. Les mat\u00e9riaux d'\u00e9tanch\u00e9it\u00e9 de la vanne papillon sont du NBR, du VITON, un rev\u00eatement en t\u00e9flon, etc., et les mat\u00e9riaux d'\u00e9tanch\u00e9it\u00e9 m\u00e9talliques sont du m\u00e9tal et des t\u00f4les lamin\u00e9es r\u00e9silientes. De tels mat\u00e9riaux pr\u00e9sentent \u00e9galement d'excellentes performances d'\u00e9tanch\u00e9it\u00e9 \u00e0 basse temp\u00e9rature.<\/p>\n

Caract\u00e9ristiques de la vanne papillon pneumatique\u00a0:<\/h2>\n

1. Le roulement de la vanne papillon pneumatique ZECO est \u00e9tendu. Le roulement \u00e9tendu peut r\u00e9duire la friction de la tige et maintenir un couple inf\u00e9rieur\u00a0;<\/p>\n

2. La tige de la vanne papillon pneumatique ZECO est con\u00e7ue de mani\u00e8re anti-\u00e9ruption. Cette conception prot\u00e8ge les mainteneurs lorsque la maintenance est requise ;<\/p>\n

3. Le joint de la vanne papillon pneumatique ZECO adopte un joint lamin\u00e9. Ce joint lamin\u00e9 peut aider la vanne \u00e0 maintenir z\u00e9ro fuite pendant l'\u00e9tat de fermeture compl\u00e8te\u00a0;<\/p>\n

4. Le si\u00e8ge de la vanne papillon pneumatique ZECO peut choisir un si\u00e8ge stell\u00e9. Le si\u00e8ge int\u00e9gral \u00e0 face m\u00e9tallique peut aider la vanne \u00e0 r\u00e9duire la maintenance et \u00e0 prolonger sa dur\u00e9e de vie.<\/p>\n
