vanne en acier inoxydable<\/a> peut g\u00e9n\u00e9rer un certain d\u00e9placement et appuyer contre la surface d'\u00e9tanch\u00e9it\u00e9 \u00e0 l'extr\u00e9mit\u00e9 de sortie pour assurer l'\u00e9tanch\u00e9it\u00e9 de l'extr\u00e9mit\u00e9 de sortie.<\/p>\nLa vanne a une structure simple et de bonnes performances d'\u00e9tanch\u00e9it\u00e9, mais la charge de la bille soumise au milieu de travail est enti\u00e8rement transmise \u00e0 la bague d'\u00e9tanch\u00e9it\u00e9 de sortie, il est donc n\u00e9cessaire de d\u00e9terminer si le mat\u00e9riau de la bague d'\u00e9tanch\u00e9it\u00e9 peut supporter la charge de travail de la sph\u00e9rique moyen, et lorsqu'il est soumis \u00e0 un impact \u00e0 haute pression. La sph\u00e8re peut \u00eatre d\u00e9cal\u00e9e.<\/p>\n
Ce type de structure est g\u00e9n\u00e9ralement utilis\u00e9 pour les vannes \u00e0 boisseau sph\u00e9rique moyenne et basse pression.<\/p>\n
Caract\u00e9ristiques :<\/strong><\/p>\n1 La cymbale de la valve \u00e0 chargement par le bas est utilis\u00e9e pour fournir une structure d'\u00e9tanch\u00e9it\u00e9 invers\u00e9e afin d'assurer une \u00e9tanch\u00e9it\u00e9 fiable de la garniture.<\/p>\n
2 La structure de vanne m\u00e9tallique mobile pr\u00e9charg\u00e9e par le ressort \u00e0 lame a une conception de force d'\u00e9tanch\u00e9it\u00e9 raisonnable, une ouverture et une fermeture flexibles et une \u00e9tanch\u00e9it\u00e9 fiable.<\/p>\n
3 Selon les besoins des utilisateurs, il peut \u00eatre con\u00e7u pour \u00eatre adapt\u00e9 aux structures contenant des particules moyennes, des mat\u00e9riaux, etc., ou des structures \u00e0 haute r\u00e9sistance \u00e0 la temp\u00e9rature.<\/p>\n
Principe de fonctionnement:<\/strong><\/p>\nLe robinet \u00e0 tournant sph\u00e9rique haute pression a un mouvement de 90 degr\u00e9s de rotation, le corps du bouchon est une sph\u00e8re, avec un trou traversant circulaire ou un passage \u00e0 travers son axe. Le robinet \u00e0 tournant sph\u00e9rique est principalement utilis\u00e9 dans le pipeline pour couper, distribuer et modifier le sens d'\u00e9coulement du fluide. Il n'a besoin d'\u00eatre tourn\u00e9 que de 90 degr\u00e9s et le couple peut \u00eatre ferm\u00e9 herm\u00e9tiquement.<\/p>\n
Les principales caract\u00e9ristiques du robinet \u00e0 tournant sph\u00e9rique haute pression sont sa structure compacte, son \u00e9tanch\u00e9it\u00e9 fiable, sa structure simple et son entretien pratique. La surface d'\u00e9tanch\u00e9it\u00e9 et la surface sph\u00e9rique sont souvent ferm\u00e9es, pas facilement \u00e9rod\u00e9es par le milieu, faciles \u00e0 utiliser et \u00e0 entretenir, adapt\u00e9es \u00e0 l'eau, aux solvants, \u00e0 l'acide et au gaz naturel. Milieu de travail, mais convient \u00e9galement aux m\u00e9dias avec de mauvaises conditions de travail.<\/p>\n
Le corps du robinet \u00e0 tournant sph\u00e9rique peut \u00eatre int\u00e9gr\u00e9 ou combin\u00e9.<\/p>\n
Performance:<\/strong><\/p>\nLe produit est class\u00e9 en un joint m\u00e9tallique et un joint souple en fonction de ses performances d'\u00e9tanch\u00e9it\u00e9. Le mod\u00e8le d'utilit\u00e9 pr\u00e9sente les avantages d'une structure compacte, d'un petit volume, d'un fonctionnement fiable, de bonnes performances d'\u00e9tanch\u00e9it\u00e9, d'un entretien facile, d'une installation pratique et d'une forte adaptabilit\u00e9. Particuli\u00e8rement adapt\u00e9 aux occasions o\u00f9 le milieu est visqueux, contenant des granules ou fibreux.<\/p>\n
Applications :<\/strong><\/p>\nPeut \u00eatre largement utilis\u00e9 dans les secteurs du p\u00e9trole, de la chimie, de l'\u00e9quipement p\u00e9dagogique, de l'industrie l\u00e9g\u00e8re, de l'\u00e9quipement haute tension, de la pharmacie, du papier et d'autres syst\u00e8mes industriels de contr\u00f4le automatique pour le contr\u00f4le centralis\u00e9 \u00e0 longue distance ou le contr\u00f4le local.<\/p>\n
