Abstract

''DISPOSITIVO REGULADOR DO TEMPO DE FECHAMENTO DE VáLVULA DE DESCARGA, TORNEIRA OU REGISTRO'' do tipo que compreende: uma entrada (11) e uma saída de água (12) comunicáveis entre si através de uma sede de vedação (14); uma câmara de equilíbrio (CE) comunicável com a saída de água (12) através de uma sede de disparo (16) e alojando um cursor vedante (20) operativamente associado à sede de vedação (14); e um conduto de equilíbrio (23) definindo uma comunicação fluida restrita entre a câmara de equilíbrio (CE) e a saída de água (12). O dispositivo regulador compreende uma válvula (V) definindo uma porção da extensão do conduto de equilíbrio (23) e tendo um corpo tubular (70) alojando um vedante (80) elasticamente deformável, para variar a seção transversal de passagem de água através da válvula (V) de modo inversalmente proporcional ao diferencial de pressão hidráulica reinante entre a câmara de equilíbrio (CE) e a entrada de água (11).'' DEVICE REGULATOR FOR CLOSING TIME OF DRAIN VALVE, TAP OR LOG '' of the type comprising: an inlet (11) and an outlet of water (12) communicable with each other through a sealing seat (14); a balance chamber (CE) communicable with the water outlet (12) through a firing seat (16) and housing a sealing slider (20) operatively associated with the sealing seat (14); and a balance duct (23) defining a restricted fluid communication between the balance chamber (CE) and the water outlet (12). The regulating device comprises a valve (V) defining a portion of the extension of the balance duct (23) and having a tubular body (70) housing an elastically deformable seal (80), to vary the cross section of water passage through the valve (V) inversely proportional to the hydraulic pressure differential between the balance chamber (CE) and the water inlet (11).
