Abstract

válvula de controle de ar quente para instalação metalúrgica. a invenção se refere a uma válvula de controle de ar quente (10) para instalação metalúrgica, em particular para o controle do fluxo de ar quente de um alto-forno. a válvula de controle de ar quente (10) compreende um alojamento de válvula metálico (12) com revestimento refratário (20) em que é definido um canal de gás (22); e um membro de válvula (24) rotativamente disposto no canal de gás (22), para poder variar a passagem livre no canal de gás (22) com a rotação do membro de válvula (24) em torno do eixo de rotação (26) entre a posição aberta e a posição fechada. o membro de válvula (24) tem um envelope com simetria rotacional em torno do eixo de rotação (26) e tem uma passagem contínua (28) disposta no membro de válvula (24) em direção transversal ao eixo de rotação (26) do membro de válvula (24). a passagem contínua (28) tem uma seção transversal substancialmente idêntica àquela da passagem de gás (22). além disso, a passagem contínua (28) está disposta no membro de válvula (24), para estar alinhada ao canal de gás (22) quando o membro de válvula (24) está em sua posição aberta.Hot air control valve for metallurgical installation. The invention relates to a hot air control valve (10) for metallurgical installation, in particular for controlling the hot air flow of a blast furnace. the hot air control valve (10) comprises a refractory lined metal valve housing (12) in which a gas channel (22) is defined; and a valve member (24) rotatably disposed in the gas channel (22) so that the free passage in the gas channel (22) can be varied with the rotation of the valve member (24) about the rotation axis (26) between the open position and the closed position. valve member (24) has an envelope with rotational symmetry about the axis of rotation (26) and has a continuous passageway (28) disposed on the valve member (24) in a direction transverse to the axis of rotation (26) of the member of valve (24). the continuous passage (28) has a cross section substantially identical to that of the gas passage (22). furthermore, the continuous passageway (28) is disposed on the valve member (24) to be aligned with the gas channel (22) when the valve member (24) is in its open position.
