The invention relates to a shut-off valve (1) for pipes (2) and/or reservoirs for receiving liquids. The shut-off valve (1) comprises a dividable valve housing (3) with an inlet opening (4). A spherical closing element (5) which also has an inlet opening (4') is arranged in the inlet opening (4) in a sliding and/or rotational manner. The closing element (5) is enclosed by two half shell-shaped sealing cups (6, 7), which form an inlet opening (4'') corresponding to the inlet opening (4') of the closing element (5) and are made of a material that is softer or more elastic than the closing element (5). The sealing cups (6, 7) at least on their opposite faces (8) each have a circular element (9, 9') for securing them between the housing halves, the valve housing (3, 3') or the flange (28) of the valve housing (3, 3'). Said element or the two circular flanges (9, 9') can be fitted into a recess (16) in the valve housing (3, 3') and are directly or indirectly held together by means of the valve housing (3, 3').
L'invention concerne un robinet d'arrêt (1) destiné à des canalisations (2) et/ou à des réservoirs devant recevoir des liquides. Ce robinet d'arrêt (1) comporte un corps (3) divisable et pourvu d'un orifice d'admission (4). Un élément de fermeture sphérique (5) comportant également un orifice d'admission (4') est monté coulissant et/ou rotatif dans l'orifice d'admission (4). Cet élément de fermeture (5) est entouré de deux coupelles d'étanchéité (6, 7) en forme de demi-coquille, lesquelles forment un orifice d'admission (4'') correspondant à l'orifice d'admission (4') de l'élément de fermeture (5) et sont constituées d'un matériau plus mou ou plus élastique que l'élément de fermeture (5). Les coupelles d'étanchéité (6, 7) présentent, au moins sur leurs faces opposées (8), un système circulaire (9, 9') permettant leur fixation entre les moitiés de corps, le corps de robinet (3, 3') ou bien la bride (28) du corps de robinet (3, 3'). Ce système ou bien les deux brides circulaires (9, 9') se logent dans un évidement (16) du corps de robinet (3, 3') et sont maintenus ensemble directement ou indirectement au moyen de ce corps (3, 3').
