Abstract

MECANISMO DE APERTO PARA VáLVULA PARA MASSA SEMIFLUIDA. A presente invenção refere-se a um mecanismo de aperto para uma válvula para massa semifluida, em que a válvula para massa semifluida tem uma sede de válvula, para assentamento de um elemento de fechamento de válvula conduzido em uma haste de válvula, um elemento de acionamento acoplado rosqueadamente com a haste de válvula, o elemento de acionamento sendo rotativo em relação à haste de válvula, para movimentar axialmente a haste de válvula e o elemento de fechamento de válvula em relação à sede de válvula, para abrir e fechar a válvula para massa semiflulda, e um meio de acionamento para girar o elemento de acionamento, o mecanismo de aperto compreendendo: um corpo de acoplamento tendo um furo rosqueado internamente para receber rosqueadamente a haste de válvula; e um meio de retenção atuável com o corpo de acoplamento, para apertar o corpo de acoplamento ao meio de acionamento, de modo a travar a haste de válvula e o elemento de acionamento conjuntamente e permitir que girem em uníssono, para retificar a incrustação da sede de válvula e do elemento de fechamento de válvula, quando são posicionados um contra o outro.
