Abstract

restritores de fluxo e conjunto de válvula. trata-se de um restritor de fluxo para o uso em um conjunto de válvula de segurança operada por piloto (porv) com uma válvula piloto que regula a operação de uma válvula principal para reduzir a pressão em um sistema ou receptáculo. em uma realização, o restritor de fluxo é configurado com uma pluralidade de regiões de modificação de fluxo, a saber, uma primeira região e uma segunda região que são separadas da primeira região. essas regiões são configuradas para gerar fluxo na saída do restritor de fluxo que induz a operação da válvula piloto que é favorável para a operação da válvula principal. em um exemplo, a primeira região e a segunda região definem, respectivamente, uma primeira área de fluxo e uma segunda área de fluxo para o trajeto de fluxo, em que cada uma é configurada para determinar uma razão da segunda área de fluxo para a primeira área de fluxo com um valor menor do que.
