Patent
CA 2321701
The invention relates to a connection for connecting a measuring device (6) to a gas pipe, comprising: a connecting element (1) for arranging in the gas pipe which divides the gas pipe into a first and a second piece (2, 3); a connecting plug (4) which can be coupled to the connecting element and which is connected to the measuring device by means of a measuring line (5), wherein the connecting element comprises a valve which is actuable by the connecting plug and which normally mutually connects the first and the second piece of the gas pipe and which, when the connecting plug is coupled to the connecting element, connects the first piece of the gas pipe to the measuring line and closes the second piece of the gas pipe. As a result of these measures the valve is operated by the connecting plug, so that opening and closing of taps is no longer necessary. The operation of such a connection is therefor greatly simplified. A perhaps even more important advantage lies in the fact that safety is ensured, since when the connecting plug is removed the measuring line is automatically closed.
L'invention porte sur un raccord permettant de brancher un dispositif de mesure (6) sur une conduite de gaz et comprenant: un élément de raccordement (1) monté sur la conduite et la divisant en une première et une deuxième partie (2, 3); et un bouchon de raccordement (4) se vissant sur l'élément de raccordement, relié au dispositif de mesure par un tuyau de mesure (5), et muni d'une soupape actionnée par ledit bouchon. Ladite soupape, qui relie normalement la première partie de la conduite de gaz à la deuxième, fait communiquer, lorsque le bouchon est vissé sur l'élément de raccordement, la première partie de la conduite de gaz avec le tuyau, et isole la deuxième partie de la conduite. De ce fait, la soupape étant commandée par le bouchon de raccordement, il n'est plus nécessaire d'ouvrir et de fermer de robinets, et le fonctionnement du raccord s'en trouve grandement simplifié. Un avantage peut-être encore plus important réside dans la sécurité puisque le tuyau de mesure s'obture automatiquement quand on dévisse le bouchon de raccordement.
