Abstract

Se proporciona una válvula de doble retención que incluye una válvula de retención de entrada en línea y una válvula de retención de salida, que cooperan para evitar el contraflujo de fluido a través de la válvula. La válvula de retención también incluye por lo menos una ventilación que permite drenar el fluido atrapado dentro de la válvula de retención, evitando así el congelamiento de la válvula de retención y el hidrante al cual se interconecta. La válvula de retención proporcionada omite muchos componentes superfluos y de este modo es más pequeña y más fácil de instalar que las válvulas de retención de la técnica anterior.
