Abstract
La presente invencion se refiere a una válvula de exceso de flujo que comprende un disco con varilla deslizable dentro de una cámara que tiene unorificio en un extremo. Esta válvula permite ajustar los umbrales de velocidad de flujo, más alláde los cuales se producirá el cierre de la válvula. Asimismoposibilita realizar ajustes precisos externamente, girando un elemento roscado que se extiende a través de la válvula, lo cual hace que un retén, que seencuentra enroscado en dicho elemento, se mueva lateralmente en el interior de la cámara. Este movimiento hace que una superficie angulada sobre el reténentre en contacto y se deslice contra una superficie angulada similar ubicada sobre el disco con varilla. A medida que el discocon varilla es impulsado endireccion al retén por accion de un resorte helicoidal, se mueve longitudinalmente dentro de la cámara, ya sea acercándose o alejándose delorificio. Al girar el elemento roscado, se ajusta con precision la distancia máxima de desplazamiento del disco con varilla, y en consecuencia, el umbralde velocidad de flujo de la válvula. Asimismo, pueden preverse medios adicionales destinados a ampliar el espectro de ajuste, sin reemplazar elresorte nimodificar el tamano del orificio, como por ejemplo separadores destinados a cambiar la tension del resorte y diversas posiciones deintroduccion del elemento de regulacion en el cuerpo de la válvula. También se incluye el método para el ajuste del umbral de velocidad de flujo, en unsistema de gas o fluido que contiene gas natural, petroleo líquido o sustancia similar, bajo presion, mediante dicha válvula.The present invention relates to an excess flow valve comprising a sliding rod disc within a chamber having a hole at one end. This valve allows you to adjust the flow rate thresholds, beyond which the valve will close. It also makes it possible to make precise adjustments externally, by turning a threaded element that extends through the valve, which makes a retainer, which is screwed onto said element, move laterally inside the chamber. This movement causes an angled surface on the retainer to contact and slide against a similar angled surface located on the rod disc. As the rod disc is driven in the direction of the retainer by the action of a coil spring, it moves longitudinally within the chamber, either approaching or moving away from the hole. By rotating the threaded element, the maximum displacement distance of the rod disc is adjusted, and consequently, the valve flow velocity threshold. Also, additional means intended to extend the adjustment spectrum can be provided, without replacing the spring or modifying the size of the orifice, such as for example spacers intended to change the spring tension and various positions of introduction of the regulating element in the valve body. Also included is the method for adjusting the flow rate threshold, in a gas or fluid system that contains natural gas, liquid petroleum or similar substance, under pressure, by means of said valve.
