Abstract

"VáLVULA DUPLA COM CAPACIDADE ANTIAGARRAMENTO". Sistema de válvula de controle que tem uma carcaça que define uma entrada, uma saída e uma descarga. Uma primeira passagem se estende entre a entrada e a saída e uma segunda passagem se estende entre a saída e a descarga. Uma primeira pluralidade de válvulas são colocadas dentro da primeira passagem na qual cada uma da primeira pluralidade de válvulas são móveis entre uma posição não-atuada onde a primeira passagem está fechada, uma posição atuada onde a primeira passagem está aberta e uma posição intermediária onde a primeira passagem está parcialmente aberta. Uma segunda pluralidade de válvulas são colocadas dentro da segunda passagem, na qual cada uma da segunda pluralidade de válvulas são móveis entre uma posição não-atuada onde a segunda passagem está aberta, uma posição atuada onde a segunda passagem está fechada, e uma posição intermediária onde a segunda passagem está parcialmente aberta. Uma pluralidade de elementos de reajuste são engatáveis de maneira seletiva com a primeira pluralidade de válvulas. A pluralidade de elementos de reajuste são operáveis para mover a primeira pluralidade de válvulas para a posição não-atuada quando uma pressão é aplicada à pluralidade de elementos de reajuste. A pluralidade de elementos de reajuste tem cada um uma haste "antiagarramento" que se estende a partir deles para impedir operação do sistema de válvula de controle se qualquer um da pluralidade de elementos de reajuste está agarrado.
