Abstract

Patente de Invenção:<B>"SEGMENTO DE ADMISSãO DE UMA CARCAçA DE TURBINA"<D>. Para a realização de parâmetros especialmente altos de vapor vivo (temperatura de vapor vivo, pressão de vapor vivo) numa turbina a vapor, o segmento de admissão (1) da carcaça de turbina possui dentro dele uma junta de flange (4, 5) para uma câmara de válvula (2) para válvulas de comando (3) possuindo uma série de aberturas de passagens (7), uma superfície de vedação (15) que cerca cada uma das aberturas de passagens (7). Para uma vedação especialmente confiável obtém-se uma pressão superficial na área da superfície de vedação pelo fato de que por um lado o contorno externo (16) da superfície de vedação (15) na área entre aberturas de passagens vizinhas (7) é executado de modo talhado e de que, por outro lado, são dispostos utilmente parafusos (6) de dimensões diferentes ao longo deste contorno externo talhado (16).
