Abstract
Actuation method for a valve at the time of closure, wherein the valve comprises a plug and an associated actuator. According to the invention, if the actuator detects that closure is not possible due to the presence of impurities or any other obstacle preventing the complete closure of the valve, the valve plug is retracted, thereby disengaging the valve parts, and the assembly is then reset to perform the closure again, this sequence of attempting closure and retracting the plug being repeated continuously as many times as programmed in the actuator. In addition, the magnitude of the retraction of the plug of the valve can have a value of 1 ° or more and can vary throughout the sequence, thereby removing the impurities and allowing the valve to close without the need for an operator to be involved.
Description
PROCEDIMIENTO DE ACTUACIÓN DE UNA VALVULA EN EL MOMENTO DE PROCEDURE FOR ACTUATING A VALVE AT THE TIME OF
CIERRE CLOSING
OBJETO DE LA INVENCIÓN OBJECT OF THE INVENTION
Es objeto de la presente invención, tal y como el título de la invención establece, un procedimiento de actuación de una válvula de fluidos en el momento del cierre, particularmente cuando se encuentra un problema, generalmente impurezas. It is an object of the present invention, as the title of the invention establishes, a procedure for actuating a fluid valve at the time of closure, particularly when a problem is encountered, generally impurities.
Caracteriza a la presente invención el hecho de permitir solucionar un problema de obstrucción de una válvula de forma automática y sin intervención alguna de operarios o personal de control. The present invention characterizes the fact of allowing to solve a problem of clogging a valve automatically and without any intervention of operators or control personnel.
Por lo tanto, la presente invención se circunscribe dentro del ámbito de las válvulas de fluido cualquiera que sea su tipología, y en particular dentro del ámbito del control y maniobra de las mismas. Therefore, the present invention is circumscribed within the scope of the fluid valves whatever their typology, and in particular within the scope of the control and maneuver thereof.
ANTECEDENTES DE LA INVENCIÓN BACKGROUND OF THE INVENTION
Una válvula es un instrumento de regulación y control de fluido, es decir, un dispositivo mecánico con el cual se puede iniciar, detener o regular la circulación (paso) de líquidos o gases mediante una pieza movible que abre, cierra u obstruye en forma parcial uno o más orificios o conductos. A valve is a fluid regulation and control instrument, that is, a mechanical device with which the circulation (passage) of liquids or gases can be initiated, stopped or regulated by a movable part that opens, closes or partially obstructs one or more holes or ducts.
En general las válvulas automáticas o industriales están comandadas por un actuador. Un actuador es un dispositivo capaz de transformar energía hidráulica, neumática o eléctrica en la activación de un proceso con la finalidad de generar un efecto sobre un proceso automatizado. Este recibe la orden de un regulador o controlador y en función a ella genera la orden para activar un elemento final de control, como por ejemplo una válvula. Son los elementos que influyen directamente en la señal de salida del automatismo, modificando su magnitud según las instrucciones que reciben de la unidad de control.
Los tipos de válvulas son numerosos y van desde los tipos de válvula de bola, mariposa, compuerta, de aguja, de bola. In general, automatic or industrial valves are controlled by an actuator. An actuator is a device capable of transforming hydraulic, pneumatic or electrical energy into the activation of a process in order to generate an effect on an automated process. This receives the order of a regulator or controller and based on it generates the order to activate a final control element, such as a valve. They are the elements that directly influence the output signal of the automatism, modifying its magnitude according to the instructions they receive from the control unit. The types of valves are numerous and range from the types of ball, butterfly, gate, needle, ball valve.
Sucede que durante el proceso de cierre del obturador de una válvula por parte del actuador, cuando el obturador en el movimiento de cierre se encuentra con un obstáculo, generalmente impurezas, el actuador deja de seguir accionando el obturador, dejando incompleto el proceso de cierre. Generalmente se produce un aviso en un puesto de control donde el operario a cargo del control y supervisión tiene que volver a resetear el actuador para que inicie de nuevo el cierre y si no pudiera así de esta manera lograr el cierre es preciso tener que desplazar personal de supervisión a verificar que ha pasado. It happens that during the closing process of the shutter of a valve by the actuator, when the shutter in the closing movement encounters an obstacle, generally impurities, the actuator stops operating the shutter, leaving the closing process incomplete. Generally, a warning is produced at a checkpoint where the operator in charge of the control and supervision has to reset the actuator to start the closing again and if it could not do so in this way to achieve the closing it is necessary to have to move personnel of supervision to verify what has happened.
Todo el proceso es costoso en tiempo y mano de obra necesaria para poder solucionar el problema de un cierre de una válvula por presencia de impurezas durante el proceso de cierre. The entire process is costly in time and labor needed to solve the problem of a valve closing due to the presence of impurities during the closing process.
Por lo tanto, es objeto de la presente invención desarrollar un procedimiento de actuación sobre el conjunto formado por una válvula y el actuador asociado a dicha válvula tal que se logre de forma automática, sin intervención humana alguna, la solución del problema de falta de cierre por presencia de impurezas o similares, desarrollando un procedimiento como el que a continuación se describe y queda recogido en su esencialidad en la reivindicación primera. Therefore, it is the object of the present invention to develop an actuation procedure on the assembly formed by a valve and the actuator associated with said valve such that the solution of the problem of non-closing is achieved automatically, without any human intervention. by the presence of impurities or the like, developing a method as described below and is included in its essentiality in the first claim.
DESCRIPCIÓN DE LA INVENCIÓN DESCRIPTION OF THE INVENTION
Es objeto de la presente invención un procedimiento de actuación de una válvula en el momento del cierre, donde la válvula cuenta con un actuador asociado encargado de accionar el obturador de la válvula, donde si el actuador detecta la imposibilidad de cierre por presencia de impurezas o cualquier otro obstáculo que permita el cierre completo del obturador de la válvula decide retroceder el obturador de la válvula ligeramente, lo que produce un proceso de desembrague de las piezas de la válvula procediendo de nuevo a armar de nuevo el conjunto y a continuación proceder a cerrar de nuevo, repitiéndose de forma continua esta secuencia de intento de cierre y retroceso del obturador tantas veces como se haya programado el actuador.
El orden de magnitud del retroceso del obturador una vez detectada la imposibilidad de cierre, es del orden de unos grados que puede ir desde 1o en adelante hasta la magnitud que se considere necesaria. The object of the present invention is a procedure for actuating a valve at the time of closure, where the valve has an associated actuator responsible for operating the valve plug, where if the actuator detects the impossibility of closing due to the presence of impurities or any other obstacle that allows the complete closure of the valve plug decides to retract the valve plug slightly, which results in a disengagement process of the valve parts proceeding to reassemble the assembly and then proceed to close again, repeating this sequence of attempt to close and reverse the shutter as many times as the actuator has been programmed. The order of magnitude of the recoil of the shutter once the impossibility of closing is detected, is of the order of a few degrees that can go from 1 or onwards to the magnitude that is considered necessary.
Como consecuencia de la secuencia continua de cierre y retroceso ligero repetido de forma continua se origina un movimiento continuo del fluido que fuerza a la retirada de las impurezas de la boca de obturación, logrando resolver el problema de forma automática sin intervención alguna de operarios, y sin tener que incluso tener que desplazarse hasta el lugar donde se encuentra la válvula. As a consequence of the continuous sequence of continuous closing and slight backward movement, a continuous movement of the fluid that forces the removal of the impurities from the sealing mouth is originated, managing to solve the problem automatically without any operator intervention, and without even having to travel to the place where the valve is located.

El actuador (2) es el encargado de producir y gobernar el movimiento del obturador de la válvula (1 ), que dependiendo del tipo de válvula (1 ) presentará unas características constructivas diferentes. The actuator (2) is responsible for producing and governing the movement of the valve plug (1), which depending on the type of valve (1) will have different construction characteristics.
Cuando en el proceso de cierre de una válvula (1 ), el obturador se encuentra con un problema que impide su cierre, de acuerdo a la invención, el actuador (2) se encarga de hacer retroceder al obturador en su avance ligeramente, del orden unos grados, produciendo el desembragado de todas las piezas de la válvula (1 ), para a continuación armar el conjunto y proceder al cierre, repitiendo esta secuencia de retroceso y cierre de forma continua tantas veces como haya sido programado el actuador (2). When in the process of closing a valve (1), the shutter encounters a problem that prevents its closure, according to the invention, the actuator (2) is responsible for pushing back the shutter in its advance slightly, of the order a few degrees, producing the disengagement of all the parts of the valve (1), to then assemble the assembly and proceed to closing, repeating this sequence of recoil and closing continuously as many times as the actuator (2) has been programmed.
Como se ha señalado anteriormente, el proceso de retroceso y cierre produce un efecto forzado en el fluido que en su movimiento arrastra las impurezas y los obstáculos que estuvieran impidiendo el cierre del conjunto. As noted above, the process of recoil and closure produces a forced effect on the fluid that in its movement drags away the impurities and obstacles that were preventing the closure of the assembly.
En la secuencia de retroceso del obturador y posterior cierre, la magnitud de retroceso producido durante la secuencia no tiene por qué ser siempre la misma pudiendo vahar a lo largo de todo el proceso, pudiendo ser dicha variación más o menos amplia a lo largo de toda la secuencia. In the shutter return sequence and subsequent closure, the amount of recoil produced during the sequence does not always have to be the same being able to go throughout the entire process, and said variation may be more or less wide throughout the entire process. sequence.
