Abstract

The attachment, designed to be mounted upstream of a liquid discharge valve (2) has a selective locking mechanism for the valve stem (3), made in the form of a peg (25) with an appropriate control system (28) to lock the valve stem or allow it to slide freely. The peg cooperates with a slider (15) situated immediately upstream of the valve, moving coaxially with its stem and consisting of a cylindrical core sliding in a tubular guide. The core has an annular recess (16) to receive the locking peg (25).
