Abstract
"VáLVULA ESFéRICA PARA O CONTROLE DO ESCOAMENTO DE MATERIAIS SóLIDOS PARTICULADOS E GASES. Uma válvula para alimentação de material particulado abrasivo para um, e para a retirada do material particulado de um reservatório pressurizado, adaptada de modo a operar a temperaturas acima de 500 C, compreende uma estrutura de válvula em que um único elemento de fechamento de formato em geral esférico realiza tanto a função de fechamento do material particulado quanto a de vedação hermética ao gás por meio de um elemento de vedação circular inflável resiliente que engata o lado convexo do dito elemento de fechamento. O dito elemento de vedação é inflado e resfriado por meio de um filete de água líquida que flui de maneira contínua e regulado a pressão. O elemento de vedação fica protegido dos danos provocados pelas temperaturas elevadas ao contatar o mesmo com o elemento de fechamento resfriado quando a válvula está fechada e ao contatar o mesmo com uma extensão circular resfriada do elemento de fechamento quando a válvula se encontra aberta.
