摘要

Leakage detector in valves for liquids characterized by the fact that in the detection zone coinciding with a tightness seal between the valve body and the sealing rod, there is an annular element that separates the packing into two parts, according to a transverse plane, which annular element is retained in the packing itself and has at least one radial through hole, so that a leakage of liquid originating in the reference zone, by infiltration between the above-mentioned stem and packing, is captured by the annular element and the liquid is evacuated through the radial orifices, towards the outside to show the escape of liquid and, therefore, the existence of a defect of hermeticity.
