Description du robinet-vanne haute pression\u00a0:<\/h2>\n

Lorsque la pression est faible, l'\u00e9paisseur de la bride est faible, l'augmentation des co\u00fbts n'est pas importante, la contrainte thermique g\u00e9n\u00e9r\u00e9e lors du chauffage et du refroidissement est faible, comptez sur la force de serrage des boulons et le joint pour obtenir une \u00e9tanch\u00e9it\u00e9 facile. Il est plus pratique de r\u00e9parer ou de remplacer la vanne lorsqu'un raccord \u00e0 bride est utilis\u00e9. La pression de service du robinet-vanne haute pression ZECO est tr\u00e8s \u00e9lev\u00e9e. Si la bride est toujours reli\u00e9e au tuyau, l'\u00e9paisseur de la bride est tr\u00e8s grande. Non seulement le co\u00fbt de la bride et du boulon est \u00e9videmment augment\u00e9, mais la contrainte thermique g\u00e9n\u00e9r\u00e9e par le chauffage et le refroidissement est \u00e9galement tr\u00e8s importante. \u00c0 mesure que la pression augmente, la temp\u00e9rature du fluide de travail augmente \u00e9galement, le boulon dans le travail \u00e0 long terme \u00e0 haute temp\u00e9rature appara\u00eet la relaxation, r\u00e9duit la bride \u00e0 la pression du joint facile \u00e0 provoquer une fuite du joint. La fuite d'un tiers s'est produite non seulement rapidement, et la fuite \u00e0 grande vitesse du fluide est facile \u00e0 souffler hors de la rainure perforante de la surface d'\u00e9tanch\u00e9it\u00e9 de la bride, la r\u00e9paration est plus difficile. Si la vanne et le tuyau sont soud\u00e9s, le poids et le co\u00fbt sont consid\u00e9rablement r\u00e9duits, la contrainte thermique pendant le chauffage et le refroidissement est consid\u00e9rablement r\u00e9duite, les performances d'\u00e9tanch\u00e9it\u00e9 sont consid\u00e9rablement am\u00e9lior\u00e9es et une fois qu'une fuite se produit, elle est facile \u00e0 g\u00e9rer.<\/p>\n

Caract\u00e9ristiques du robinet-vanne haute pression\u00a0:<\/h2>\n

1. Le robinet-vanne haute pression ZECO adopte g\u00e9n\u00e9ralement le VT (inspection visuelle) pour les produits soud\u00e9s afin de v\u00e9rifier les d\u00e9fauts de soudage \u00e9vidents, tels que les fissures, les bordures, les rots de soudage, les d\u00e9fauts de moulage, les br\u00fblures, les \u00e9claboussures, etc. Apr\u00e8s avoir pass\u00e9 le visuel le plus \u00e9l\u00e9mentaire inspection, PT est utilis\u00e9 pour v\u00e9rifier s'il y a des fissures dans la surface d'\u00e9tanch\u00e9it\u00e9 et pour tester la duret\u00e9 de la surface d'\u00e9tanch\u00e9it\u00e9\u00a0;<\/p>\n

2. L'\u00e9crou de tige du robinet-vanne haute pression ZECO est rempla\u00e7able en ligne\u00a0;<\/p>\n

3. Le si\u00e8ge arri\u00e8re du robinet-vanne haute pression ZECO est con\u00e7u pour soulager la contre-pression sur la garniture de tige lorsqu'il est compl\u00e8tement en place\u00a0;<\/p>\n

4. Les anneaux de si\u00e8ge du robinet-vanne haute pression ZECO sont soud\u00e9s herm\u00e9tiquement pour fournir un joint \u00e9tanche aux bulles.<\/p>\n
