Title (EN) PINCH VALVE
(FR) VANNE À MANCHON
Abstract: front page image
(EN)The present invention concerns a pinch valve (1) comprising a hollow cylindrical main body (10) internally comprising a longitudinal axial opening (20) having, on a transverse plane, a substantially elliptical profile defined by the union of two arcs of circumference, the central segment of each of said arcs of circumference having a substantially radial rib (14) extending from it, and in that it comprises, on said main body, at least one narrowing area (13) defined by the joining of two conical tapered segments (13a, 13b). The pinch valve according to the present invention, among the other advantages, makes it possible, for the same passage port, to minimise the closing stroke of the valve, thus reducing the opening and closing times thereof.
(FR)La présente invention concerne une vanne à manchon (1) comprenant un corps principal cylindrique creux (10) comprenant intérieurement une ouverture axiale longitudinale (20) ayant, sur un plan transversal, un profil sensiblement elliptique défini par l’union de deux arcs de circonférence, le segment central de chacun desdits arcs de circonférence ayant une nervure sensiblement radiale (14) s’étendant depuis celui-ci, et celle-ci comprend, sur ledit corps principal, au moins une zone de rétrécissement (13) définie par l’assemblage de deux segments effilés coniques (13a, 13b). La vanne à manchon selon la présente invention, entre autres avantages, permet, pour le même orifice de passage, de réduire au minimum la course de fermeture de la vanne, de façon à réduire les temps d’ouverture et de fermeture de celle-ci.
