Abstract
Válvula de alivio para el bombeo de hormigón en moldes encofrantes, concretamente para encofrados de túneles, galerías o similares, que evita que el encofrado este sometido a presiones más elevadas de la admisible. Comprendido por un sistema de seguridad y un soporte que lo une a la estructura encofrante. El sistema de seguridad contiene en un orificio (1) en la superficie de la estructura encofrante que se cierra con una placa circular (2) cuando la presión del encofrado no supera la admisible, un resorte (3) y una barra roscada (5) a una tuerca. Cuando la presión supera a la admisible, el resorte (3) se comprime y la barra roscada (5) desciende junto con la placa circular (2), dejando una abertura por la que saldrá el hormigón, aliviando y alertando de una presión superior a la admisible no deseada.
