Abstract

"CONJUNTO REFRATáRIO PARA UM DISPOSITIVO REGULAGEM DA VELOCIDADE DE UM VAZAMENTO". A invenção diz respeito a um conjunto refratário para um dispositivo para regulagem da velocidade de vazamento. A jusante do canal de vazamento (7) ficam compreendidas de, pelo menos, duas placas refratárias (1,2) perpendiculares a um eixo do canal (Z-Z) e providas de os respectivos orifícios (10, 20). O dispositivo inclui, a montante da placas, mecanismo para injeção de um fluido (F) capaz de cooperar mecanicamente com o vazamento (C). De acordo com a invenção, esta injeção é efetuada a montante das placas e em um setor angular do canal (7) menor do que 360<198>, na direção do deslocamento (X-X) da placa corrediça (1) em direção à sua posição de interrupção."REFRACTORY ASSEMBLY FOR A LEAK SPEED ADJUSTMENT DEVICE". The invention relates to a refractory assembly for a device for regulating leakage velocity. Downstream of the leakage channel (7) are comprised of at least two refractory plates (1,2) perpendicular to a channel axis (Z-Z) and provided with the respective holes (10, 20). The device includes, upstream of the plates, a fluid injection mechanism (F) capable of mechanically cooperating with the leak (C). According to the invention, this injection is performed upstream of the plates and in an angular sector of the channel (7) of less than 360 <198>, in the direction of travel (XX) of the sliding plate (1) towards its position. of interruption.
