Abstract:
Valve or tap for fluids, consisting of a body, a stopper in said body that rotates between an open and closed position, a control rod for said stopper equipped with a throttle or grip lever, where said throttle or grip lever is fixed to said rod by means of a fastening screw and has, on one of the parts that are concentric to said rod, two end-of-turn shoulders, set at an angle, which come to rest against a catch on one side of said body, in order to define the open and closed positions of the stopper, characterised by the fact that the throttle or grip lever (14) has, in addition, on said part with the end-of-turn shoulders, at least one blocking notch (19, 20), designed to fit tightly with the said catch (18), in order to keep the throttle or lever and, with it the stopper, in a pre-determined fixed position, either closed or open, to prevent it from turning, and by the fact that said fastening screw (15) has a special head that allows it to be screwed/unscrewed only with a specific key or tool in order to block the throttle or lever, thereby preventing tampering, at least when the stopper has to stay in a fixed position.
