Abstract

L'invention se rapporte à une vanne comprenant un corps muni de raccords d'arrivée et de départ et de sièges d'obturateurs respectivement associés aux deux raccords et sur chacun desquels un élément mobile s'appuie à joint étanche dans la position de fermeture de la vanne, les deux éléments mobiles tant reliés à un mécanisme de manoeuvre commun; la vanne présente une chambre entourée par le corps, limitée par les sièges des obturateurs et qui est fermée lorsque la vanne est fermée. Pour pouvoir utiliser commodément cette vanne pour le contrôle de l'étanchéité, qui est particulièrement important dans les installations de chauffage au gaz, la chambre est munie d'un raccord approprié pour le branchement d'un manomètre ou d'un détecteur de pression, de manière à pouvoir servir de chambre de mesure de l'étanchéité.The invention relates to a valve comprising a body provided with inlet and outlet fittings and shutter seats respectively associated with the two fittings and on each of which a movable element rests with a sealed seal in the closed position of the valve. the valve, the two movable elements both connected to a common operating mechanism; the valve has a chamber surrounded by the body, limited by the valve seats and which is closed when the valve is closed. In order to be able to conveniently use this valve for checking the tightness, which is particularly important in gas heating installations, the chamber is provided with a suitable connection for the connection of a manometer or a pressure detector, so as to be able to serve as a chamber for measuring the tightness.
