Abstract

VáLVULA DE INJEçãO QUìMICA SUBMARINA COMPENSADA POR PRESSãO Uma válvula protegida contra retro pressão, adequada para aplicações de injeção química para tratamento de poços submarinos inclui uma válvula gaveta aperfeiçoada, uma válvula de retenção e um compensador de pressão que reage á pressão hidrostática ambiente. A válvula de retenção pode consistir de uma válvula de elevação em um corpo de saída separável. O compensador de pressão consiste de um pistão móvel em um cilindro. A parte do cilindro sobre um lado do pistão está exposta à água do mar, enquanto a parte do cilindro no lado oposto do pistão é preenchida com um fluido hidráulico selecionado. Dessa forma, o acionador da válvula não fica exposto aos efeitos corrosivos e/ou de contaminação da água do mar.
