Descri\u00e7\u00e3o da v\u00e1lvula:
\nTipo de v\u00e1lvula: V\u00e1lvula de esfera flutuante
\nMaterial do corpo: 2205.
\nDi\u00e2metro nominal: DN80
\nClassifica\u00e7\u00e3o de press\u00e3o: PN25
\nConex\u00e3o final: Flange RF
\nTemperatura de trabalho: -29\u2103~+200\u2103.
\nOpera\u00e7\u00e3o: Alavanca.<\/p>\n

Introdu\u00e7\u00e3o ao produto da v\u00e1lvula de esfera de a\u00e7o 2205
\n1. A v\u00e1lvula de esfera de a\u00e7o 2205 adota as vantagens diferenciadas dos tipos flutuantes e fixos
\n1. V\u00e1lvula de esfera flutuante
\nA v\u00e1lvula de esfera flutuante adota o design "esfera flutuante + autoveda\u00e7\u00e3o de m\u00e9dia press\u00e3o". Sua esfera \u00e9 conectada \u00e0 haste da v\u00e1lvula apenas atrav\u00e9s da haste superior. Sob a a\u00e7\u00e3o da press\u00e3o m\u00e9dia, ela pode produzir um pequeno deslocamento, de modo que a esfera se encaixe firmemente na sede da v\u00e1lvula do lado de sa\u00edda para obter a veda\u00e7\u00e3o. Essa estrutura apresenta tr\u00eas vantagens significativas:<\/p>\n

Vantagem de baixo custo: estrutura simples e compacta, pequeno n\u00famero de pe\u00e7as e custo de fabrica\u00e7\u00e3o cerca de 30% menor que o da v\u00e1lvula de esfera fixa;
\nCapacidade de resposta r\u00e1pida: a rota\u00e7\u00e3o de 90\u00b0 pode completar a abertura e o fechamento, o que \u00e9 particularmente adequado para cenas que exigem opera\u00e7\u00e3o frequente;
\nMecanismo de veda\u00e7\u00e3o adapt\u00e1vel: ele ainda pode manter uma boa veda\u00e7\u00e3o em condi\u00e7\u00f5es de baixa press\u00e3o, mas deve-se prestar aten\u00e7\u00e3o \u00e0 sele\u00e7\u00e3o do material do assento da v\u00e1lvula em condi\u00e7\u00f5es de alta press\u00e3o.
\n2. V\u00e1lvula de esfera fixa
\nA v\u00e1lvula de esfera fixa fixa a esfera no centro do corpo da v\u00e1lvula atrav\u00e9s das hastes duplas superior e inferior, e a sede da v\u00e1lvula adota um design flutuante m\u00f3vel. Suas principais vantagens s\u00e3o:<\/p>\n

Adaptabilidade a alta press\u00e3o: pode suportar press\u00e3o de at\u00e9 2500LB, adequado para condi\u00e7\u00f5es de press\u00e3o ultra-alta;
\nCapacidade de veda\u00e7\u00e3o bidirecional: estrutura exclusiva de bloco duplo e fileira dupla, pode bloquear a m\u00eddia a montante e a jusante ao mesmo tempo;
\nDesign de longa vida \u00fatil: o anel de veda\u00e7\u00e3o do assento da v\u00e1lvula \u00e9 feito de material el\u00e1stico PTFE, com um dispositivo de pr\u00e9-carga de mola para garantir confiabilidade de veda\u00e7\u00e3o a longo prazo.
\nSele\u00e7\u00e3o de grande di\u00e2metro: cobertura de maior di\u00e2metro, DN300~DN2000
