The invention relates to a ball valve having a housing (4) made of plastic in which a carrier structure (3) is disposed that is encased in plastic in which a valve ball (2) having a through opening (5) is pivotally supported between an opening and closing position, said carrier structure (3) comprising two carrier rings (10a, 10b) positioned opposite each other, and a connecting element (11) connecting said carrier rings (10a, 10b). In order to create a ball valve made of plastic that is characterized by a simple construction and improved impermeability, the invention provides for the carrier structure (3) to separate the valve ball (2) completely from the plastic of the housing (4).
L'invention concerne une soupape à bille comprenant un corps (4) en plastique dans lequel est disposée une structure porteuse (3) entourée par le plastique, une bille de soupape (2) pourvue d'une ouverture de passage (5) étant montée rotative dans cette structure porteuse (3) entre une position d'ouverture et une position de fermeture. Ladite structure porteuse (3) se compose de deux anneaux porteurs (10a, 10b) opposés recevant la bille de soupape (2) et d'un élément de liaison (11) reliant ces anneaux porteurs (10a, 10b). L'objectif de l'invention est de créer une soupape à bille en plastique caractérisée par une facilité de production et une étanchéité améliorée. À cet effet, la structure porteuse (3) sépare totalement la bille de soupape (2) du plastique du corps (4).
