Abstract

Valve for container containers of extinguishing products, which being of the type that incorporate a valvular body provided with means of attachment to the container, preferably a body neck in whose bosom plays a sealed piston capable of occupying two positions, corresponding to those of opening and closing of the valve, and in which there are two complementary sectors, one that receives permanently, through its front, the pressure of the container and another that plays in a chamber to which an overpressure supplied by any meter sends the the corresponding information per environmental, resting said piston on a calibrated rod, capable of supporting the pressure applied permanently to its front, but which is sheared by the piston itself when it accesses pressure to the auxiliary chamber, essentially characterized by the outlet of the valve is established radially, that is to say perpendicularly to the piston, having foreseen that e the oversized sector of said piston, intended to play in the overpressure chamber, is located beyond said outlet and hermetically isolated from it both in the closed situation and in the valve opening situation, all in order that the overpressure supplied to said chamber is not lost with the opening of the valve itself, with the particular feature that the calibrated retention rod for the piston which is located at the end of the body opposite to the coupling to the container and from which on it, a bushing associated with a cylindrical neck strikes the axial prolongation of said rod, following its oversized sector, it being further provided that said calibrated can be replaced by a laminar disk, also calibrated.
