  • Acetylene (C 2 H 2 ) is a widely used gas for fuel and in chemical reactions. It is highly flammable and can decompose explosively if the absolute pressure of the gas exceeds about 200 kPa. It is therefore commonly shipped and stored dissolved at low pressure in a carrier liquid such as acetone ((CH 3 ) 2 CO) or DimethylFormaldehyde (DMF) in a cylinder with a porous filling.
  • a carrier liquid such as acetone ((CH 3 ) 2 CO) or DimethylFormaldehyde (DMF) in a cylinder with a porous filling.
  • acetylene The typical use flow rate of acetylene is low enough that it is used as it evolves from the acetone. This is important as if the acetone escapes the cylinder into the gas delivery line it can have deleterious effects on certain rubbers and plastics which are commonly used in the process equipment such as in regulators and torches. This will cause the lines to rot and leak. Acetone is also itself highly flammable and can destabilise a flame generated by burning acetylene. It is therefore very important to ensure no acetone leaves the cylinder.
  • Acetone cylinders are normally stored and transported upright, so that no acetone comes into contact with the valve entrance. However, the cylinder could be transported or placed onto its side accidentally or unavoidably and the acetone would then come into contact with the valve

  • Acetylene is dissolved in the liquid acetone 12, and evolves from the liquid acetone 12 into the space 11. In normal use the evolution happens at a rate such that acetylene is evolved at least as quickly as it is dispensed from the cylinder.

Abstract

L'invention concerne une vanne de cylindre, laquelle vanne a un corps et un élément de vanne mobile entre une position fermée, pour empêcher la fuite d'un fluide, et une position ouverte, pour permettre l'échappement d'un fluide. La vanne a également un capteur d'orientation pour mesurer l'orientation de la vanne par rapport à un axe de référence. Un processeur est configuré pour détecter si la vanne est orientée selon un angle de seuil ou en dessous de ce dernier sur la base de l'orientation, déterminer si la vanne a été orientée au-dessus de l'angle de seuil pendant une longueur prédéterminée de temps, et empêcher l'élément de vanne de se déplacer à partir de la position fermée jusqu'à la position ouverte si l'axe de vanne n'a pas été orienté au-dessus de l'angle de seuil pendant la longueur prédéterminée de temps.
