ABSTRACT:
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.
