Definitions

  • the present invention concerns an under-valve device for the interception of a flow for preventing the complete emptying of gas bottles, maintaining inside said bottles a predetermined residual pressure, and that allows the free loading of said bottles.
  • valves are known - inserted in series behind the tap with a pin valve that opens and closes the gas bottles - provided with an obturator consisting of a small spring piston that opens the passage for the gas only when the pressure inside the bottle reaches a value superior to the one of a predetermined calibration. Said valves have many and heavy inconveniences:
  • the aim set forth is reached by means of the device according to he present invention, mainly consisting of an under-valve for the interception of the flow that may be inserted between the top of the bottle and the delivery tap or behind the tap, provided with two parallel means for the alternative passage of the gases in the two senses, for the loading of the bottle and for the delivery, that are automatically operated by the pressure of the gases according to a predetermined calibration.
  • Figure 1 shows a vertical scheme of an under-valve device for the interception of the flow for gas bottles according to the present invention.
  • FIG. 1 shows in detail the components of one of the parallel alternative gas passage means.
  • Figure 3 shows the under-valve and the tap mounted together.
  • Figure 4 shows the under-valve realized in one piece with the tap.
  • the enclosed figures show an under-valve device for the interception of a flow for gas bottles, comprising:
  • said means A consists in a vertical duct 10 performed in the structure S body, connected with the valve room 11 in which the following components are provided:
  • edge 7 has also the function of a rest.
  • said means B consists of a vertical duct 8 and of a valve room 9 parallel and opposite to the corresponding duct 10 and room 11 of above mentioned means A, realized with identical components like the already described elements 1, 2, 3, 4 ,5, 6, 7.
  • the gas under pressure comes in from tap R, meets hole 12 of the bottom 2 of the valve A and when entering the holes 5, closes the valve A;
  • the gas enters through the duct 8 into valve B overcoming the resistance of its spring 3 so that the obturator 1 moves backwards and the gas enters the valve room 9 and through hole 5 of the obturator 1 passes through a cavity 13 of the obturator and, through the hole 12 of the bottom 2, enters into the bottle;
  • said means A and B work in a sense opposite to the one already described.
  • the device may be installed for the outlet after the delivery tap R, instead like an under- valve between the gas bottle and said tap R; in such case, different connection shapes are requested for different gas kinds.

Abstract

Le dispositif de la présente invention se présente sous la forme d'une sous-valve (S) destinée à couper le flux de gaz. Ce dispositif peut être placé entre le haut de la bouteille de gaz et le robinet (R) de sortie du gaz ou il peut former une seule pièce avec le robinet. Il est pourvu de deux moyens parallèles (A) et (B) pour le passage alterné du gaz dans les deux directions, respectivement pour remplir et vider la bouteille, ces deux moyens fonctionnant automatiquement, selon un étalonnage prédéterminé, sous l'effet d'une pression prédéterminée du gaz, pour éviter que la bouteille ne soit vidée complètement.
