Principe<\/b>:<\/b>\u00a0<\/b><\/b><\/p>\n

Les vannes \u00e0 engrenages servent de vannes marche-arr\u00eat efficaces avec un d\u00e9bit dans les deux sens. Dans une telle conception, une cale coulisse \u00e0 travers un passage g\u00e9n\u00e9ral afin de contr\u00f4ler le d\u00e9bit de fluide (comme une porte coulissante, d'o\u00f9 son nom). L'une des caract\u00e9ristiques les plus importantes de ce type de vannes \u00e0 engrenages est son passage direct et d\u00e9gag\u00e9 lorsqu'elle est r\u00e9gl\u00e9e en position compl\u00e8tement ouverte. Ceci est rendu possible par le fait que la cale se soul\u00e8ve enti\u00e8rement hors du passage. En cons\u00e9quence, les vannes industrielles se caract\u00e9risent par un minimum de turbulences et de chutes de pression en fonctionnement.<\/p>\n

Bien que les vannes \u00e0 engrenages conviennent aux applications n\u00e9cessitant ces deux facteurs, elles ne sont pas recommand\u00e9es pour les installations dans lesquelles l'\u00e9tranglement serait une fonction. Ils sont con\u00e7us pour un service marche\/arr\u00eat.<\/p>\n

Les vannes \u00e0 engrenages comportent une cale flexible, sauf indication contraire du client. La cale flexible se d\u00e9place le long du corps de la vanne lors de l'ouverture et de la fermeture, \u00e9tant maintenue en position par une fente de guidage qui minimise la friction entre le si\u00e8ge du corps et la cale. Cette conception est particuli\u00e8rement adapt\u00e9e pour compenser les l\u00e9g\u00e8res d\u00e9formations thermiques produites par le tube de la vanne lui-m\u00eame, garantissant ainsi une meilleure \u00e9tanch\u00e9it\u00e9 entre le corps et les si\u00e8ges de cale.<\/p>\n

Caract\u00e9ristiques\uff1a<\/b><\/b><\/p>\n

1. Petite r\u00e9sistance \u00e0 l'\u00e9coulement pour le fluide\u00a0;<\/p>\n

2. Seule une petite force est requise pour l\u2019ouverture\/fermeture\u00a0;<\/p>\n

3. Aucune limitation sur la direction d'\u00e9coulement du milieu\u00a0;<\/p>\n

4. Pendant le processus d'ouverture et de fermeture, la friction entre la cale du disque et le si\u00e8ge est faible, de sorte que l'\u00e9tanch\u00e9it\u00e9 est fiable, garantissant l'\u00e9tanch\u00e9it\u00e9 et une longue dur\u00e9e de vie\u00a0;<\/p>\n

5. L'\u00e9tanch\u00e9it\u00e9 de la tige de valve est r\u00e9alis\u00e9e gr\u00e2ce \u00e0 la collaboration de graphite flexible et tiss\u00e9. assurer une \u00e9tanch\u00e9it\u00e9 plus fiable\u00a0;<\/p>\n

6. Type de chapeau \u00e0 joint de pression en option\u00a0;<\/p>\n

7. Type \u00e0 coin plein en option\u00a0;<\/p>\n

8. Structures de tige non montantes facultatives\u00a0;<\/p>\n

9. Structure de veste en option.<\/p>\n
