La vanne \u00e0 guillotine bidirectionnelle manuelle est une vanne \u00e0 guillotine unidirectionnelle utilis\u00e9e sur les pipelines industriels pour un fonctionnement marche-arr\u00eat.<\/p>\n
La structure du corps et du si\u00e8ge \u00e9limine le colmatage du flux de particules fines. De plus, le bord du couteau biseaut\u00e9 aide<\/p>\n
le portail coupe facilement les supports \u00e9pais. Selon diff\u00e9rentes situations de travail\u00a0: vanne \u00e0 guillotine \u00e0 tige non montante, couteau \u00e0 plaquettes<\/p>\n
Vanne \u00e0 guillotine, vanne \u00e0 guillotine \u00e0 ergots, vanne \u00e0 guillotine pneumatique, vanne \u00e0 guillotine \u00e9lectrique, vanne \u00e0 guillotine manuelle et biseau<\/p>\n
Les vannes \u00e0 guillotine \u00e0 engrenages sont toutes disponibles<\/p>\n
Caract\u00e9ristiques:<\/b><\/p>\n
1. Corps :<\/p>\n
a) Le corps int\u00e9gral avec structure \u00e0 passage int\u00e9gral assure un \u00e9coulement fluide, un assemblage facile et une possibilit\u00e9 de fuite de coque plus petite.<\/p>\n
b) La conception du corps sans rainure \u00e9limine tout colmatage potentiel lors de la fermeture de la vanne.<\/p>\n
2. Porte\u00a0:<\/p>\n
a) Le bord du couteau biseaut\u00e9 offre une forte contrainte de coupe et une \u00e9tanch\u00e9it\u00e9 \u00e9tanche.<\/p>\n
b) L'\u00e9paisseur de la porte peut \u00eatre augment\u00e9e pour r\u00e9pondre \u00e0 une pression plus \u00e9lev\u00e9e.<\/p>\n
3. Si\u00e8ge\u00a0:<\/p>\n
a) Le si\u00e8ge en \u00e9lastom\u00e8re en forme de U assure une \u00e9tanch\u00e9it\u00e9 p\u00e9riph\u00e9rique le long du bord de la porte et assure une \u00e9tanch\u00e9it\u00e9 parfaite dans les deux sens.<\/p>\n

4. Autre :<\/p>\n
a) Le double roulement de but\u00e9e minimise le couple requis pour le fonctionnement<\/p>\n
