Abstract

L'invention concerne un dispositif pour empêcher d'endommager une armature de conduit et tout type de récipient contre les effets de dilatation de l'eau et de quelconques solutions aqueuses en cas de gel. Ce dispositif consiste en un type d'armature de conduit comprenant un clapet de fermeture ou de régulation, et un siège. Le déplacement du clapet par rapport au siège se fait sous l'action d'un champ magnétique. Le changement des paramètres du champ magnétique entraînant un déplacement de l'élément de fermeture ou de régulation se fait par le déplacement manuel d'un ou de plusieurs aimants faisant partie du dispositif et constituant une partie de la chaîne magnétique et/ou un changement de température des propriétés magnétiques des pièces faisant partie du dispositif. Les pièces changeant de propriétés magnétiques sous l'action de la température font également partie de la chaîne magnétique, et le changement de leurs propriétés magnétiques entraîne également un changement des paramètres de la chaîne magnétique se traduisant par un déplacement du clapet par rapport au siège. La pièce changeant de propriétés magnétiques entraînant un déplacement du clapet par rapport au siège est faite entièrement ou partiellement d'un matériau ayant une température de Curie de -5С à +5С.
