Discharge valve in a turbomachine

The valve has a gate (116) designed to be mounted to pivot about a shaft (120) between a closed position of an orifice for passage of air and an open position of the orifice. A seal (152) extends along a portion of a peripheral edge (156) of the gate. A plate (158) attaches the seal to the periphera...

Zusammenfassung:	The valve has a gate (116) designed to be mounted to pivot about a shaft (120) between a closed position of an orifice for passage of air and an open position of the orifice. A seal (152) extends along a portion of a peripheral edge (156) of the gate. A plate (158) attaches the seal to the peripheral edge of the gate, where the gate and the seal attachment plate are made of plastic, and are formed as single piece or welded/bonded together. The gate and/or the attachment plate are made of a thermoplastic material that is reinforced with fibers such as glass fibers. Vanne de décharge dans une turbomachine, comprenant une porte (116) destinée à être montée pivotante autour d'un axe (120) pour l'ouverture et la fermeture d'un orifice de passage d'air, un joint d'étanchéité (152), et des moyens (158) de fixation du joint sur le bord périphérique de la porte, la porte et les moyens de fixation étant réalisés en matériau plastique et formés d'une seule pièce ou rendus solidaires l'un de l'autre par soudage ou collage.
