Abstract

1. Grifo con registro giratorio esférico, del tipo en el cual el registro tiene un eje en que se consigue la estanqueidad por el apoyo de un asiento desplazable en la dirección de la vena fluida, dispuesto en la parte anterior, en el sentido de la corriente , del registro, y susceptible de trabajar a altas temperaturas y sometido a fuertes presiones, caracterizado en que la parte anterior del asiento (14) forma una superficie axial de apoyo para el fluido a manera de collarín (18) sobre el cual se aplica la presión de la vena fluida con interposición de un trozo de fuelle (19) o una membrana metálica, un extremo del cual está fija con estanqueidad sobre el cuerpo (2) del grifo y cuyo otro extremo está fijado con estanqueidad sobre el asiento móvil (14), mientras que el extremo del asiento se apoya sobre el registro a través de un labio metálico (16) elásticamente deformable; hay previstos medios susceptibles de asegurar un equilibrio de la presión, a uno y otro lado del asiento, previamentea la abertura del grifo. 2. Grifo según la reivindicación 1, caracterizado en que los medios que aseguran el equilibrio de la presión a uno y otro lado del asiento, previamente a la abertura del grifo, están constituidos por un conducto by-pass (23) que desemboca por una parte en la vena fluida, anteriormente del asiento deslizable y, por otra parte en la cámara (24) existente entre el cuerpo y el asiento, estando equipado con un grufo de cierre (21). 3. Grifo según una cualquiera de las reivindicaciones 1 y 2, caracterizado en que está equipado con un asiento, en la parte posterior según el sentido del fluido (25), que comprende elementos de grafito (26), mantenido apoyados elásticamente contra el registro (4) mediante un elemento (27) en forma de toro metálico abieto en el exterior. 4. Grifo según una cualquiera de las reivindicaciones 1 a 3, caracterizado en que la sección de paso de la zona de apoyo de la parte posterior del asiento (25) sobre el registro (4) es menor que la sección depaso en la zona de apoyo de la parte anterior del asiento (14) sobre el mismo. 5. Grifo según cualquiera de las reivindicaciones 1 a 4, caracterizado en que el registro (4) comprende una labio metálico deformable (28) destinado a vener a apoyarse contra el labio deformable (16) de la parte anterior del asiento. 6. Grifo con registro giratorio esférico.
