Patent

CA 2538394

The invention relates to a flowmeter for regulating and monitoring the flow of sealing fluid to be conducted to a seal of a rotating shaft, the meter comprising a sealing fluid metering channel (3), a sealing fluid inlet (4) and a connection (5) towards the seal for regulating the flow of sealing fluid, a non-return valve (21) for preventing the sealing fluid from flowing back to the flowmeter, a regu-lating and monitoring mechanism (10, 12, 14), whereby the sealing fluid flows through the opening (13), and a cleaning means (17) which is movable by means of actuating means (16, 18). The non-return valve (21) is arranged as an extension of the metering channel (3) at the meter outlet (5) side end, co--axially with the metering channel, whereby the metering cone (10) is in me-chanical contact with the non-return valve (21), and thus it is also possible to clean the non-return valve with the cleaning means (17).

L'invention concerne un débitmètre permettant de réguler et de surveiller l'écoulement de fluide d'étanchéité qui est acheminé vers un joint d'arbre rotatif, le débitmètre comprenant un canal de dosage de fluide d'étanchéité (3), un orifice d'entrée de fluide d'étanchéité (4) et une connexion (5) vers le joint pour réguler l'écoulement du fluide d'étanchéité, un clapet de non-retour (21) pour empêcher le fluide d'étanchéité de retourner vers le débitmètre, un mécanisme de régulation et de surveillance (10, 12, 14), ce qui permet au fluide d'étanchéité de s'écouler à travers l'ouverture (13), et un moyen de nettoyage (17) qui est mobile grâce à un moyen d'actionnement (16, 18). Le clapet de non-retour (21) est agencé comme extension du canal de dosage (3) au niveau de la sortie du débitmètre (5) côté extrémité, de manière coaxiale avec le canal de dosage, le cône de dosage (10) étant en contact avec le clapet de non-retour (21), et il est ainsi également possible de nettoyer le clapet de non-retour avec le moyen de nettoyage (17).
