Abstract

“válvula de gaveta e gaveta de válvula” trata-se de uma válvula de gaveta para uso em aplicações de campo de óleo e que inclui um conjunto de vedação de haste (19) e um conjunto de vedação de sede (14). cada um dos conjuntos de vedação de haste e de sede acomoda vedações independentes primária, secundária e terciária para vedar o espaço entre a haste (20) e a tampa (30) ou anel de sede (32) e o corpo de válvula (28), respectivamente. o fornecimento de vedações múltiplas em cada conjunto fornece redundância que permite a manutenção das vedações entre os componentes mesmo se uma ou duas das vedações individuais falhar.
