Abstract

La valvula de corredera de la invencion comprende una corredera, la cual se monta en una manera que le permite moverse transversalmente al canal de pasaje. Esta valvula se proporciona con un diseno simetrico con lo cual permite que la presion prevaleciendo en el canal de pasaje alcance un lado de la corredera mediante conductos adecuados, con lo cual el otro lado no se sujeta a cualquier presion o solamente a una presion baja constante. Un resorte de presion trabaja contrario a la presion y mantiene a la corredera en la posicion abierta. En el caso de que la presion de fluido prevalezca, la corredera se desplaza hacia la posicion de bloqueo en la cual permanece hasta que la presion cae por debajo del limite de cambio una vez mas.
