Abstract

"DISPOSITIVO REGULADOR DE PRESSãO PARA MONTAGEM EM UM ALOJAMENTO DE EQUIPAMENTO ELéTRICO E SISTEMA PARA AUMENTAR AS VELOCIDADES DE ESCOAMENTO ATRAVéS DO MESMO". Um dispositivo regulador de pressão para alojamento de equipamento elétrico inclui um corpo de válvula que é dotado de um pedestal que se projeta acima de um flange de montagem e uma mesa no pedestal que suporte um conjunto de válvula de dois estágios o qual pode ser dimensionado no diâmetro independentemente da área de trabalho do flange por baixo da mesa. O traçado é particularmente aplicável a aplicações de retroajuste para equipamento de distribuição elétrica de grande porte com a pegada do dispositivo regulador de pressão fixada pelo traçado dos alojamentos de equipamento. A abertura de válvula de primeiro estágio pode ser dimensionada substancialmente como aberturas de ventilação nos alojamentos e as aberturas de válvula de segundo estágio podem ser dimensionadas na relação desejada com a abertura de primeiro estágio para otimização do desempenho de válvula independentemente das restrições impostas na pegada do dispositivo.
