Abstract

"REGULADOR DE PRESSãO PARA UMA PLANTA DE TRANSPORTE E/OU DISTRIBUIçãO DE GáS". A invenção refere-se a um regulador de pressão de gás (1) compreendendo: pelo menos uma válvula (2), um duto de fornecimento (4) de gás de baixa pressão (Pb), um obturador de regulagem (5) para o fluxo de fornecimento de gás, uma cabeça de controle (8) da referida válvula (2) definindo uma câmara superior (9) e uma câmara inferior (10); uma válvula de piloto (12) para controlar o movimento do referido obturador (5) em que existe uma primeira câmara (13) com uma via de entrada (14), uma primeira via de saída (18) comunicando com o referido duto de fornecimento (4) e uma segunda câmara (16) na qual existe o corpo de um obturador de interceptação (17) adaptado para abrir ou fechar a referida via de entrada (14). A invenção é caracterizada pelo fato de a referida primeira câmara (13) possuir pelo menos uma segunda via de saída (11) comunicando com a referida câmara inferior (10) e a referida câmara superior (9) e a referida via de entrada (14) serem ligadas entre si através de um duto auxiliar (15) contendo gás a uma pressão intermediária (Pm) entre a referida pressão alta (Pa) e a referida pressão baixa (Pb).
