Title (EN) LEAK DETECTION APPARATUS
(FR) APPAREIL DE DETECTION DE FUITES
Abstract: front page image
(EN)A leak detection apparatus (18) is provided in a pressurized assembly (10) to signal a loss of pressure or vacuum downstream from a source of pressure of vacuum. A rod (60, 160, 260) is carried on a valve (62, 162) and a diaphragm (38, 138) which seals the source of pressure or vacuum from the system. A loss of pressure or vacuum downstream of the valve (62, 162) and diaphragm (38, 138) moves the rod (60, 160, 260) to a signalling position to alert an interested party that the system is lacking pressure or vacuum.
(FR)Un appareil de detection de fuites (18) est monte dans un ensemble pressurise (10) pour signaler une perte de pression ou de vide en aval d"une source de pression ou de vide. Une tige (60, 160, 260) est portee sur une soupape (62, 162) et un diaphragme (38, 138) qui ferme de maniere etanche la source de pression ou ce vide provenant du systeme. Une perte de pression ou ce vide en aval de la soupape (62, 162) et le diaphragme (38, 138) deplace la tige (60, 160, 260) vers une position de signalisation pour alerter un operateur indiquant ainsi que le systeme manque de pression ou de vide.
