Abstract

Valve à papillon. De part et d'autre de l'axe de rotation, des ailes sont reliées à des bras de levier montés en rotation sur un axe, autour duquel un corps tubulaire, relié de façon étanche à un cadre, est muni d'échancrures latérales; dans chaque intervalle entre échancrures, un joint entoure l'axe; les ailes sont munies d'une bande de joint périphérique ; du côté intérieur du cadre ainsi que sur le corps tubulaire, est prévu pour chaque aile un porte-joint périphérique muni d'un joint élastique. Application : locaux exposés à contamination.Butterfly valve. On either side of the axis of rotation, the wings are connected to lever arms mounted in rotation on an axis, around which a tubular body, connected in a sealed manner to a frame, is provided with side notches; in each interval between notches, a seal surrounds the axis; the wings are provided with a peripheral seal strip; on the inside of the frame as well as on the tubular body, a peripheral seal carrier provided with an elastic seal is provided for each wing. Application: premises exposed to contamination.
