Description

Sistema regulador de gas.Gas regulator system.

El presente invento se refiere a un sistema regulador de gas. Usualmente un sistema regulador de gas está integrado en un EP 1 026 446 A1.The present invention relates to a system gas regulator Usually a gas regulator system is integrated in an EP 1 026 446 A1.

Un sistema regulador de gas-aire que ajusta la velocidad de la ventilación dependiendo de las necesidades de la instalación para el calor. Como resultado, una válvula multifuncional de gas entrega la cantidad correcta de gas para el valor correcto de combustión, que es controlada por el electrodo de ionización.A gas-air regulator system which adjusts the speed of ventilation depending on the installation needs for heat. As a result, a Multifunctional gas valve delivers the correct amount of gas for the correct combustion value, which is controlled by the ionization electrode

Un sistema regulador de gas-aire del tipo descrito antes se describe en el documento EP-A-0 909 922, en el que no se define mejor una válvula moduladora. Usualmente, la válvula moduladora de gas es del tipo descrito en el documento EP-A 0 669 499. Una válvula moduladora de gas de este tipo tiene varios inconvenientes, debido principalmente a la complejidad de su construcción, la necesidad de muchas piezas, resortes, aberturas, una membrana, la necesidad de calibrar el sistema y la histéresis generada por la modulación de imán entre la corriente ascendente y la descendente. El objeto del presente invento es proporcionar un sistema de regulación de gas del tipo mencionado antes que tiene unas características estructuradas simplificadas y una precisión mejorada al modular el gas. De acuerdo con el presente invento, se realiza un sistema regulador de gas acorde con la reivindicación 1. La válvula que se propone en esta memoria está compuesta por un cuerpo, hecho normalmente de aluminio, junto con las piezas usuales para conexiones y para detectar la presión de entrada y salida, una válvula magnética de seguridad adecuada para la categoría de los requisitos de la aplicación y una segunda válvula de modulación y seguridad. Esta válvula es especial, ya que está controlada por un motor lineal de impulsos, por ejemplo 0,1 - 0,2 mm por impulso. El motor lineal abre y cierra la válvula con cada impulso recibido, y la seguridad es una característica integral: tras la orden apropiada o si no hay corriente, cierra automáticamente la válvula de gas.A gas-air regulator system of the type described above is described in the document EP-A-0 909 922, in which no better define a modulating valve. Usually the valve Gas modulator is of the type described in the document EP-A 0 669 499. A gas modulating valve This type has several drawbacks, mainly due to the complexity of its construction, the need for many pieces, springs, openings, a membrane, the need to calibrate the system and hysteresis generated by magnet modulation between the upstream and downstream. The object of the present invention is to provide a gas regulation system of the type mentioned before it has structured features simplified and improved accuracy when modulating the gas. From according to the present invention, a regulatory system of gas according to claim 1. The valve proposed in this memory is composed of a body, usually made of aluminum, together with the usual parts for connections and for detect the inlet and outlet pressure, a magnetic valve adequate security for the category of requirements of the application and a second modulation and safety valve. This valve is special because it is controlled by a linear motor of pulses, for example 0.1-0.2 mm per pulse. Linear motor open and close the valve with each impulse received, and safety It is an integral feature: after the appropriate order or if there is no current, automatically close the gas valve.

En el sistema modulador de gas-aire, un interruptor analógico diferencial detecta la cantidad de aire para la combustión y, haciendo referencia a este valor, usando la válvula anterior se puede medir compatiblemente la cantidad de gas requerida (salida térmica) sin tener que preocuparse de variables en el gas, tales como su salida térmica (para la misma familia de gases) o la presión aguas arriba. Haciendo referencia a la calidad del aire para la combustión, la cantidad de gas que se entrega por la válvula siempre cumplirá con los requisitos. El proceso de modulación es muy preciso y no hay errores debidos a la histéresis.In the modulator system of gas-air, a differential analog switch detects the amount of air for combustion and by doing reference to this value, using the previous valve can be measured compatible the amount of gas required (thermal output) without having to worry about variables in the gas, such as its output thermal (for the same family of gases) or upstream pressure. Referring to the quality of the combustion air, the amount of gas delivered by the valve will always comply with the requirements. The modulation process is very accurate and there is no Errors due to hysteresis.

Una válvula multifuncional de gas compuesta de una válvula electromagnética y una válvula de motor lineal de impulsos. Además de cumplir todos los requisitos de seguridad, modular el gas, estabilizar la presión de gas cuando la presión aguas arriba varía, regular la entrega de gas si varia el tipo de gas entre los diferentes grupos de gases en la misma familia, este sistema es también innovador porque es simple de construir, no requiere calibración y los valores límite mínimo y máximo detectados por el interruptor analógico diferencial y almacenados en la memoria del microprocesador son suficientes para entregar la cantidad correcta de gas en los valores mínimo y máximo.A multifunctional gas valve composed of an electromagnetic valve and a linear motor valve of impulses In addition to meeting all security requirements, Modulate the gas, stabilize the gas pressure when the pressure Upstream varies, regulate gas delivery if the type of gas between different groups of gases in the same family, this system is also innovative because it is simple to build, not requires calibration and the minimum and maximum limit values detected by differential analog switch and stored in memory of the microprocessor are enough to deliver the amount correct gas in the minimum and maximum values.

Esta válvula de gas está construida como la válvula anterior, excepto en que tiene un sensor de presión en la salida de la propia válvula. Este sensor es el que determina la cantidad de gas a modular, todavía por medio del motor lineal de impulsos. El sensor de presión controla la modulación en los parámetros requeridos, que son controlados, por ejemplo, por un procesador.This gas valve is built as the anterior valve, except that it has a pressure sensor in the output of the valve itself. This sensor is what determines the amount of gas to be modulated, still by means of the linear motor of impulses The pressure sensor controls the modulation in the required parameters, which are controlled, for example, by a processor.

Esta válvula también puede ser usada en calderas de succión natural (que no tienen ventilación ni un interruptor analógico diferencial). Usando la presión como parámetro de referencia, la válvula no puede regular la entrega de calor si el valor calorífico del gas varía.This valve can also be used in boilers natural suction (which have no ventilation or a switch differential analog). Using pressure as a parameter of reference, the valve cannot regulate heat delivery if the Gas calorific value varies.

Las reivindicaciones de patente de esta memoria pueden ser consideradas igual que las anteriores, con la excepción de ser capaces de regular la entrega de calor.The patent claims of this specification they can be considered the same as the previous ones, with the exception of being able to regulate heat delivery.
