Abstract

Perfeccionamientos en válvulas de disco para sistemas de suministro de líquidos caracterizados porque se forma cada válvula por una caja hueca alargada con una parte intermedia agrandada entre una boca de entrada y un extremo y una boca de salida en el otro extremo, un asiento de válvula adyacente al conducto en el extremo inferior de la boca de entrada, un diafragma flexible dentro de la parte agrandada y cerrado periféricamente a la misma, quedando el diafragma transversal a la boca de entrada y a la boca de salida, una pluralidad de aberturas por lo menos en las partes exteriores del diafragma estando destinado el dispositivo sin perforar a cerrar de una forma saltable el paso en el asiento de la válvula separándose el dispositivo sin perforar del asiento de la válvula por lo que el líquido que fluye en la dirección de la boca de entrada a la boca de salida pasará libremente alrededor del dispositivo sin perforar, mientras que el líquido que fluye en la dirección de la boca de salida a la boca de entrada produce un movimiento del diafragma suficiente para poner en contacto el dispositivo sin perforar con el asiento de la válvula y detener el flujo del líquido cuando la presión del líquido, en la boca de salida supera a la presión en la boca de entrada al menos en 2,53 gramos/cm2.
