摘要

New valve model for tank unloaders, characterized in that it consists essentially of a sharpened piece that is introduced into the discharge tube, inside which it bears disinfectant pins, and at the top of which a second piece provided with an orifice is threaded. the one that introduces the cord on which the actuating lever acts, having placed between both pieces a cup of flexible material of frustoconical shape, which is the one that effects the closing by the own pressure of the water whose weight it supports.
