There is to be created a gas flow monitoring device in which the adjustment/alteration of the reseat flow can also be made without the need of changes to its design, that is to say even after its manufacture. In particular, it should be possible to adjust the reseat flow at the time of its installation on site. To this end, the gas flow monitoring device consists of a gas-tight casing (1) with a valve seat (6) in its interior for a reseat body (14) that can freely move inside the casing (1). Said reseat body (14) is fastened to a pin (11) that is supported by bearings located in both the inlet guide (7) and the outlet guide (8). Said reseat body (14) is kept in open position by a reseat spring (16) that rests with its one end on the outlet guide (8) and with its other end on the reseat body (14) itself. At the inlet guide (7) there is arranged a spacer block (17) that acts as a stop point (18) for the reseat body (14) with the gas flow monitoring device in open position.

Dispositif de contrôle d'un écoulement de gaz dans lequel le réglage ou la modification du débit est possible sans modifications structurales, et donc aussi une fois la fabrication dudit dispositif terminée. La présente invention doit également permettre que le réglage du débit puisse être effectué seulement au moment de l'installation. A cet effet, ledit dispositif de contrôle est composé d'un boîtier (1) étanche aux gaz qui possède dans son intérieur un siège (6) de soupape pour un obturateur (14) mobile dans le boîtier (1). L'obturateur (14) est fixé sur une tige (11) montée dans un passage d'entrée (7) et dans un passage de sortie (8). Un ressort d'obturation (16), qui s'appuie d'un côté sur le passage de sortie (8) et de l'autre sur l'obturateur (14), maintient ledit obturateur en position ouverte. Sur le passage d'entrée (7) est placé un élément d'écartement (17) qui forme une butée (18) pour l'obturateur (14) dans la position ouverte du dispositif de contrôle d'écoulement de gaz.
