Title (EN) IMPROVED STOPCOCK
(FR) ROBINET D'ARRET AMELIORE
Abstract: front page image
(EN)A valve (12) for controlling the flow of a gas therethrough which requires no machining in order to attain an effective seal between the valve seating surface and a rotatable plug element (26). The valve seat surface (24) remains as-cast while the plug consists of an overmolded plastic. The overmolding defines an array of pliable sealing ridges. The use of overmolding facilitates the use of cost-saving plastic materials and obviates the need for expensive machining of the cooperating surfaces.
(FR)L'invention concerne une vanne de régulation de l'écoulement d'un gaz à travers celle-ci ne nécessitant pas d'usinage pour obtenir un joint efficace entre la surface d'assise de la vanne et un élément obturateur tournant. La surface de siège de vanne reste brute de coulée tandis que l'obturateur se compose d'un plastique surmoulé. Le surmoulage définit un ensemble de nervures d'étanchéité pliables. L'utilisation d'un surmoulage facilite l'emploi de matières plastiques économiques et évite l'usinage coûteux des surfaces concourantes.
