CA 2141665

An air seal valve (8) is formed from an annular valve body (20) having a circular valve plate (12) disposed internally thereof with a pair of axially spaced valves (34 and 50) thereon defining a fresh air plenum (28), wherein one of the valves (50) includes a truncated conical plate having a radially outer edge (54) engageable with the valve body (20) to effect a seal thereagainst. Clean air under pressure greater than the pressure of contaminated emissions flowing into the valve is conducted by a manifold (26) to an outer plenum (22). The clean air flows from the plenum (22) through a plurality of apertures (30) in the valve body (20) to the inner plenum (28). In the event of an imperfect seal within the valve (8), the clean air flows through the leak path into a conduit (10), ensuring that contaminated emissions do not escape past the valve (8).

Vanne hermétique (8) pour circuit d'air composée d'un corps annulaire (20) muni d'une plaque circulaire (12) de vanne placée à l'intérieur et d'une paire de vannes (34 et 50) espacées axialement définissant une chambre (28) d'air frais. L'une desdites vannes (50) comporte une plaque tronconique présentant un bord extérieur radial (54) venant au contact du corps (20) de vanne de façon à former un joint étanche. De l'air propre sous une pression supérieure à celle des émissions polluées s'écoulant dans la vanne est conduit par une tubulure (26) vers une chambre extérieure (22). L'air propre s'écoule de la chambre (22) à travers une série d'ouvertures pratiquées dans le corps (20) de vanne vers la chambre intérieure (28). En cas de défaut d'étanchéité de la vanne (8), l'air propre emprunte le cheminement des fuites et rejoint un conduit (10), ce qui garantit que les émissions polluantes ne franchissent pas la vanne (8).
