1. Introduction \u00e0 l'utilisation de la vanne \u00e0 boisseau sph\u00e9rique cryog\u00e9nique DQ41F<\/p>\n

1. La vanne \u00e0 boisseau sph\u00e9rique cryog\u00e9nique d\u00e9signe la vanne dont la temp\u00e9rature du fluide est comprise entre -40\u2103 et -196\u2103. Les vannes cryog\u00e9niques courantes sont divis\u00e9es en vannes papillon cryog\u00e9niques, vannes \u00e0 opercule cryog\u00e9niques, vannes \u00e0 boisseau sph\u00e9rique cryog\u00e9niques, vannes \u00e0 soupape cryog\u00e9niques, clapets anti-retour cryog\u00e9niques, vannes d'\u00e9tranglement cryog\u00e9niques, etc. La vanne \u00e0 boisseau sph\u00e9rique cryog\u00e9nique DQ41F convient au syst\u00e8me de gestion des \u00e9quipements de stockage et de transport de liquides cryog\u00e9niques. Le fluide \u00e0 basse temp\u00e9rature produit, tel que l'\u00e9thyl\u00e8ne, l'oxyg\u00e8ne liquide, l'hydrog\u00e8ne liquide, le gaz naturel liqu\u00e9fi\u00e9, les produits p\u00e9troliers liqu\u00e9fi\u00e9s, etc., est non seulement inflammable et explosif, mais doit \u00e9galement \u00eatre gaz\u00e9ifi\u00e9 lorsqu'il est chauff\u00e9, et son volume se dilate des centaines de fois lors de la gaz\u00e9ification.<\/p>\n

2. Le mat\u00e9riau de la vanne GNL est tr\u00e8s important. Un mat\u00e9riau non qualifi\u00e9 provoquera une fuite externe ou interne du corps et de la surface d'\u00e9tanch\u00e9it\u00e9 ; les propri\u00e9t\u00e9s m\u00e9caniques globales, la r\u00e9sistance et la rigidit\u00e9 des pi\u00e8ces ne peuvent pas r\u00e9pondre aux exigences d'utilisation, voire casser. La fuite de fluide de gaz naturel liqu\u00e9fi\u00e9 provoque une explosion. Par cons\u00e9quent, dans le processus de d\u00e9veloppement, de conception et d'\u00e9laboration des vannes GNL, le mat\u00e9riau est la premi\u00e8re et la question cl\u00e9.<\/p>\n

5. Forme du si\u00e8ge de vanne : Le si\u00e8ge de vanne adopte une structure soud\u00e9e, et la surface d'\u00e9tanch\u00e9it\u00e9 est plaqu\u00e9e avec un alliage dur \u00e0 base de cobalt pour garantir les performances d'\u00e9tanch\u00e9it\u00e9 de la vanne.<\/p>\n

6. L'obturateur adopte une structure \u00e9lastique, et un trou de d\u00e9charge de pression est con\u00e7u \u00e0 l'extr\u00e9mit\u00e9 d'entr\u00e9e de pression.<\/p>\n

7. Le corps de vanne avec joint unidirectionnel est marqu\u00e9 du symbole de direction d'\u00e9coulement.<\/p>\n

8. Les vannes \u00e0 boisseau sph\u00e9rique, vannes \u00e0 opercule, vannes \u00e0 soupape et vannes papillon cryog\u00e9niques adoptent une structure \u00e0 long col pour prot\u00e9ger le presse-\u00e9toupe.<\/p>\n

9. Norme des vannes \u00e0 boisseau sph\u00e9rique ultra-cryog\u00e9niques : JB\/T8861-2004.<\/p>\n

3. S\u00e9lection des mat\u00e9riaux de la vanne \u00e0 boisseau sph\u00e9rique cryog\u00e9nique DQ41F<\/p>\n

1. Corps et chapeau de vanne adoptent : LCB (-46\u2103), LC3 (-101\u2103), CF8 (304) (-196\u2103).<\/p>\n

2. Obturateur : Acier inoxydable plaqu\u00e9 de carbure c\u00e9ment\u00e9 \u00e0 base de cobalt.<\/p>\n

3. Si\u00e8ge : Acier inoxydable plaqu\u00e9 de carbure c\u00e9ment\u00e9 \u00e0 base de cobalt.<\/p>\n

4. Tige : 0Cr18Ni9.<\/p>\n

Quatri\u00e8mement, test et inspection des vannes cryog\u00e9niques<\/p>\n

Les pi\u00e8ces principales des vannes basse temp\u00e9rature sont trait\u00e9es cryog\u00e9niquement, et chaque lot est \u00e9chantillonn\u00e9 pour un test de r\u00e9silience \u00e0 froid afin de garantir que la vanne n'est pas cassante dans des conditions de travail \u00e0 basse temp\u00e9rature et peut r\u00e9sister \u00e0 l'impact des fluides \u00e0 basse temp\u00e9rature.<\/p>\n

Les tests suivants sont effectu\u00e9s sur chaque vanne :<\/p>\n

1. Test de r\u00e9sistance de la coque \u00e0 temp\u00e9rature normale ;<\/p>\n

2. Test d'\u00e9tanch\u00e9it\u00e9 sup\u00e9rieure \u00e0 temp\u00e9rature et basse pression normales ;<\/p>\n

3. Test d'\u00e9tanch\u00e9it\u00e9 \u00e0 temp\u00e9rature et basse pression normales ;<\/p>\n

4. Test d'\u00e9tanch\u00e9it\u00e9 sup\u00e9rieure cryog\u00e9nique (en cas d'\u00e9tanch\u00e9it\u00e9 sup\u00e9rieure) ;<\/p>\n

5. Test d'\u00e9tanch\u00e9it\u00e9 au gaz \u00e0 basse temp\u00e9rature, etc., pour garantir que l'ensemble de la vanne cryog\u00e9nique r\u00e9pond aux exigences de la norme ;<\/p>\n

6. Effectuer un traitement cryog\u00e9nique sur les pi\u00e8ces principales et un test d'impact cryog\u00e9nique sur chaque lot d'\u00e9chantillons pour garantir que la vanne n'est pas cassante dans des conditions cryog\u00e9niques et qu'elle peut r\u00e9sister \u00e0 l'impact des fluides cryog\u00e9niques ;<\/p>\n

7. Les vannes cryog\u00e9niques sont soumises \u00e0 un traitement cryog\u00e9nique et \u00e0 un test d'impact conform\u00e9ment aux sp\u00e9cifications des mat\u00e9riaux correspondants ;<\/p>\n

8. La fonction \u00e9lectrostatique est plus puissante, et la r\u00e9sistance de conduction entre le corps de la vanne et la tige de la vanne ou entre les pi\u00e8ces internes et le corps de la vanne est inf\u00e9rieure \u00e0 1 ohm.<\/p>\n

Une vanne \u00e0 boisseau sph\u00e9rique cryog\u00e9nique d\u00e9signe une vanne dont la temp\u00e9rature du fluide est comprise entre -40\u2103 et -196\u2103.
