Abstract

Improvements in safety valves for the adduction network of liquids of the type comprising a valve element maintained applied to a seat by means of a spring where the compression rate determines the threshold of opening of the valve, characterized in that the element of valve instead of being flat as it is of use, it has, on the outside of its circular contact zone with the seat, a concave conical skirt whose concavity is turned towards the seat and which it forwards, to the outside of the latter and in reverse, the jet of liquid evacuated by the valve beyond a certain pressure in order to create a dynamic reaction force that, in the opposite direction to the closing force of the calibrated spring and proportional to the evacuated discharge, consequently to the opening of the element of valve, is added to the resulting stress of the pressure of the liquid on the valve element, to compensate the growth of tension of the calibrated spring, in order to maintain the debit coefficient at its optimum value.
