1. Introdu\u00e7\u00e3o ao uso da v\u00e1lvula esfera criog\u00eanica DQ41F<\/p>\n

1. V\u00e1lvula esfera criog\u00eanica refere-se \u00e0 v\u00e1lvula cuja temperatura do meio \u00e9 de -40\u2103 a -196\u2103. V\u00e1lvulas criog\u00eanicas comuns s\u00e3o divididas em v\u00e1lvula borboleta criog\u00eanica, v\u00e1lvula gaveta criog\u00eanica, v\u00e1lvula esfera criog\u00eanica, v\u00e1lvula globo criog\u00eanica, v\u00e1lvula de reten\u00e7\u00e3o criog\u00eanica, v\u00e1lvula de estrangulamento criog\u00eanica, etc. A v\u00e1lvula esfera criog\u00eanica DQ41F \u00e9 adequada para o sistema de gerenciamento de equipamentos de armazenamento e transporte de l\u00edquidos criog\u00eanicos. O meio de baixa temperatura de sa\u00edda l\u00edquida, como etileno, oxig\u00eanio l\u00edquido, hidrog\u00eanio l\u00edquido, g\u00e1s natural liquefeito, produtos de petr\u00f3leo liquefeito, etc., n\u00e3o \u00e9 apenas inflam\u00e1vel e explosivo, mas tamb\u00e9m precisa ser gasificado quando aquecido, e seu volume se expande centenas de vezes quando gasificado.<\/p>\n

2. O material da v\u00e1lvula de GNL \u00e9 muito importante. Material n\u00e3o qualificado causar\u00e1 vazamento externo ou vazamento interno da carca\u00e7a e da superf\u00edcie de veda\u00e7\u00e3o; as propriedades mec\u00e2nicas abrangentes, resist\u00eancia e rigidez das pe\u00e7as n\u00e3o podem atender aos requisitos de uso ou at\u00e9 mesmo quebrar. Vazamento de meio de g\u00e1s natural liquefeito causa explos\u00e3o. Portanto, no processo de desenvolvimento, projeto e desenvolvimento de v\u00e1lvulas de GNL, o material \u00e9 a quest\u00e3o prim\u00e1ria e chave.<\/p>\n

6. O castelo adota estrutura el\u00e1stica e um furo de al\u00edvio de press\u00e3o \u00e9 projetado na extremidade de entrada de press\u00e3o.<\/p>\n

7. O corpo da v\u00e1lvula com veda\u00e7\u00e3o unidirecional \u00e9 marcado com a indica\u00e7\u00e3o de dire\u00e7\u00e3o de fluxo.<\/p>\n

8. V\u00e1lvulas esfera, gaveta, globo e borboleta criog\u00eanicas adotam estrutura de pesco\u00e7o longo para proteger a gaxeta.<\/p>\n

9. Norma para v\u00e1lvula esfera ultracriog\u00eanica: JB\/T8861-2004.<\/p>\n
