Abstract

"VáLVULA COM ESFERA COM ESFERA DE DEFORMAçãO CONTROLADA PARA A INTERRUPçãO DE FLUIDO". Uma válvula com esfera de deformação controlada para interrupção de fluido compreendendo um corpo de restrição externo (11), dentro do qual é disposto um elemento de cortina (13), móvel entre uma posição de encerramento e uma posição de abertura da válvula, o elemento de cortina cooperando com um ou mais assentos (12) e fornecendo elementos de vedação com relação ao corpo de restrição e ao elemento de cortina, no qual o elemento de cortina fornece zonas de rendimento (15a) em suas partes esféricas (15) dispostas a jusante dos assentos com relação a uma zona de pressão. Preferivelmente, as zonas de rendimento são fornecidas por entalhes (19) produzidos nas zonas de superfície dos elementos de cortina em correspondência com as partes esféricas.
