Definitions

  • the invention relates to a gas-tightness control sys ⁇ tem for a singe-line gas installation in which gas under pressure is supplied to one or more tapping points.
  • gas detectors mounted at central places are used, said detectors providing an acoustic alarm in the event of the presence of gas in the atmosphere around the detectors.
  • the alarm thus warns those in the sur- roundings whenever there is gas in the atmosphere, after which the necessary steps can be taken to pre ⁇ vent accidents, such as turning off the supply of gas or ventilation etc.
  • This alarm requires the presence of person ⁇ nel who can take the necessary actions, or that the alarm is connected to an exchange from which the nec ⁇ essary steps can be taken for the disconnection of the gas .
  • This form of control is, however, both unsafe and troublesome for the users, either because the system- is dependent on the presence of persons during the. period of seepage, or that the necessary action must be taken immediately from a remotely-lying exchange.
  • control unit can be set to register an outflow which exceeds this permanent gas consumption. Finally, one can select the control period at any desired time at which there is not normally any con ⁇ sumption of gas.
  • the gas installation is a single-line pipeline which is connected to a mains supply 1 by means of a ser ⁇ vice pipe 2.
  • the gas is fed through a supply pipe 6 to the indi ⁇ vidual places of consumption via an outlet valve 7.
  • an outlet valve 7 In the individual rooms 10 are erected one or more gas detectors 8 which are connected to the control unit 5 via electric wires 11. These detectors can be mounted in such a way that they break the current be ⁇ tween the detector and the control unit whenever gas is present in the air in the room, whereupon the con ⁇ trol unit sends a signal via the cable 12 to the motor-valve 3, which immediately disconnects the sup ⁇ ply of gas to the building 9.
  • This control system will thus continually ascertain whether a seepage exists as a result of a leakage in the installation.
  • the control unit 5 is arranged to monitor a measure ⁇ ment of the flow of gas through the meter 4 for a period of, for example, 15 minutes, in order to as.- certain whether the consumption og gas exceeds the amount which, for example, a pilot light or the like consumes. If a "consumption" is ascertained in "such a period of measurement, the solenoid valve 3 is ac ⁇ tivated, in that the reason for "the consumption" must lie in a leakage in the hidden installation, or the seepage is below that level at which the gas de- tector 8 registers an escape.
  • the control unit 5 can be set to effect a continuous surveillance of the installation by controlling- whether an extraordinary consumption arises during a period of, for example, 30 minutes in a measuring cycle of either 12 or 24 hours.

Abstract

Afin de contrôler si une installation de gaz est totalement étance, on monte une vanne (3) de fermeture dans la conduite (2) de raccordement à un immeuble (9) avec un débitmètre (4) et une unité (5) de commande électronique. De plus, on peut monter des détecteurs (8) de gaz dans les pièces (10) de l'immeuble. Si du gaz est présent dans une pièce (10), le détecteur de gaz (8) envoie des signaux à la vanne magnétique (3) par l'intermédiaire de l'unité (5) de commande, après quoi l'alimentation en gaz est immédiatement couplée. On peut ainsi effectuer une vérification et donc une surveillance continue de l'installation par des mesures périodiques de la consommation de gaz, et lorsque celle-ci dépasse la normale le gaz est immédiatement coupé, car il est probable que la ''consommation'' est due à une fuite. Ainsi le système de contrôle agit indépendamment de la présence de personnes et l'on peut empêcher de manière simple et fiable les accidents résultant de fuites de gaz.
