Hot fluid (that is, liquid or gas) pipeline relief valve arranged downstream of a heat generator or of any other device emitting heat whether by design or accidentally, for example an air compressor, and upstream of the hot fluid circuit portion to be protected, preferably on a branch connected to an outlet or return pipe, characterised in that the opening of the body (9) of the valve connected to the pipe (8) is at least partly obstructed by a breakable bulb (19) filled with a liquid that expands with an increase in the temperature of the fluid conveyed by the pipeline, said bulb (19) being arranged inside the body (9) of the valve (7) in order to be in contact with the conveyed fluid. <IMAGE> |
