Abstract

"PERFIL DE ALìVIO PARA BORDA DE SEDE DE VáLVULA". Um assento de válvula possui uma superfície externa, uma extremidade traseira, uma face e uma extremidade dianteira. Uma passagem se estende da extremidade traseira para a face. Um elemento de válvula entra em contato deslizante com a face. Os flanges de alívio de tensão estão localizados na face em áreas de alta tensão de suporte. Cada flange possui uma espessura que permite que o mesmo deforme ligeiramente para reduzir as tensões de suporte.
