Abstract[English]
The check valve relates to pipeline fittings and allows fluid to flow through it in only one direction. The check valve is full-bore; the shut-off device (1) of the check valve having a drop-shaped form is hollow and the internal cavity of the shut-off device (1) is connected to the working liquid through holes. The check valve comprises an expanded diffuser (8) and a nozzle (9) narrowed in the flow direction. The nozzle (9) has twelve guide blades (10) that regulate the turbulence of the flow. The guide blades (10) partially replicate the shape of the drop-shaped shut-off device (1) and protrude beyond the nozzle (9) in the direction of the diffuser (8).[French]
Le clapet de retenue est relié à des raccords de canalisation et ne permet au fluide de s'écouler que dans une seule direction. Le clapet de retenue est à passage intégral ; son dispositif d'obturation (1) en forme de goutte est creux et sa cavité interne est reliée aux orifices par lesquels passe le liquide de travail. Le clapet anti-retour comprend un diffuseur élargi (8) et une buse (9) rétrécie dans la direction d'écoulement. La buse (9) comporte douze lames de guidage (10) régulant la turbulence de l'écoulement. Les lames de guidage (10) reproduisent partiellement la forme du dispositif d'obturation en forme de goutte (1) et dépassent de la buse (9) en direction du diffuseur (8).
