Abstract

Perfeccionamientos en válvulas de sobrepresión para estemples de minas hidráulicos, con un campo de presión de 200 a 600 bar para emulsión de aceite-agua como líquido de presión, en forma de un cartucho de sobrepresión recambiable con una corredera de émbolo sujeta en su situación de partida por fuerza de muelle, que presenta un taladro ciego axial que parte de lado de entrada, del que parten taladros de salida radiales hasta su contorno cilíndrico que acaban de ensanchamientos cónicos hacia el contorno ya los que se han matado las aristas, y un anillo tórico dispuesto detrás de los taladros de salida radiales, en sentido de corriente, en una ranura anular de la superficie de guía cilíndrica para esta corredera de émbolo, que circunda herméticamente a la corredera de émbolo, caracterizados porque la superficie exterior cilíndrica de la corredera de émbolo, que circunda herméticamente a la corredera de émbolo, caracterizados porque la superficie exterior cilíndrica de la corredera de émbolo,presenta una rugosidad de hasta aproximadamente 1 mym, el anillo tórica consta de un caucho resistente a la hidrólisis, muy resistente al desgaste por roce y florierte con una dureza Shore de aproximadamente 90 Shore A y una elasticidad de goma de aproximadamente el 20%, el diámetro de sección del anillo tórico es aproximadamente el doble del diámetro de los taladros de salida radiales de la corredera de émbolo y el diámetro interior del anillo tórico es solo un poco menor que el diámetro de la corredera de émbolo.
