Title (EN) A SLIDE VALVE FOR A TWIN-SCREW COMPRESSOR
(FR) ROBINET À TIROIR POUR COMPRESSEUR À DEUX VIS
Abstract:
(EN) The present application provides a slide valve, wherein the slide valve is configured to regulate a load of a twin-screw compressor. The slide valve comprises a slide valve body, wherein the slide valve body has a connecting end and a free end, the connecting end is configured to connect to a slide valve connecting rod of the twin-screw compressor, and the slide valve is driven to slide by the slide valve connecting rod. A cavity is formed in the free end of the slide valve body, and the slide valve has a passage configured to fluidly couple the cavity with an external fluid to reduce air flow pulsations on a suction side of the twin-screw compressor and thereby reduce overall air flow pulsations in the twin-screw compressor.
(FR) La présente invention concerne un robinet à tiroir, le robinet à tiroir étant conçu pour réguler une charge d'un compresseur à deux vis. Le robinet à tiroir comprend un corps de robinet à tiroir, le corps de robinet à tiroir possédant une extrémité de raccordement et une extrémité libre, l'extrémité de raccordement étant conçue pour être raccordée à une tige de raccordement de robinet à tiroir du compresseur à deux vis, et le robinet à tiroir étant amené à coulisser par l’intermédiaire de la tige de raccordement du robinet à tiroir. Une cavité est formée dans l'extrémité libre du corps de robinet à tiroir, et le robinet à tiroir possède un passage conçu pour accoupler fluidiquement la cavité avec un fluide externe pour réduire les pulsations d'écoulement d'air sur un côté d'aspiration du compresseur à deux vis et ainsi réduire les pulsations d'écoulement d'air globales dans le compresseur à deux vis.
