DISPOSITIVO DE PRESIÓN DE CONSIGNA VARIABLE CON ACTUADOR ELECTROMECÁNICO DE EMPUJE LINEAL  VARIABLE SET PRESSURE DEVICE WITH LINEAR PUSHING ELECTROMECHANICAL ACTUATOR
DESCRIPCIÓN DESCRIPTION
OBJETO DE LA INVENCIÓN OBJECT OF THE INVENTION
Es objeto de la presente invención, tal y como el título establece, un dispositivo de presión de consigna variable con actuador electromecánico y en particular los medios de transmisión del accionamiento desde el actuador hasta una válvula pilotada o no. It is the object of the present invention, as the title states, a variable setpoint pressure device with electromechanical actuator and in particular the transmission means of the drive from the actuator to a pilot valve or not.
Caracteriza a la presente invención las especiales singularidades constructivas que presentan los medios de transmisión del accionamiento desde el actuador hasta la válvula piloto, que hacen de los mismos un conjunto desmontable y de fácil mantenimiento. It characterizes the present invention the special constructive singularities presented by the transmission means of the drive from the actuator to the pilot valve, which make them a removable and easy maintenance assembly.
Por lo tanto, la presente invención se circunscribe dentro del ámbito de las válvulas y de manera particular de entre las válvulas de control hidráulicas controladas por piloto de regulación directamente sobre las válvulas de regulación con muelle incorporado. Therefore, the present invention is circumscribed within the scope of the valves and particularly between the hydraulic control valves controlled by regulating pilot directly on the regulating valves with built-in spring.
ANTECEDENTES DE LA INVENCIÓN En el estado de la técnica las válvulas reductoras de presión se emplean para reducir la presión al mínimo necesario dentro de la red de distribución para poder permitir el aporte de agua o fluido al punto de cota más elevada más desfavorecido de la red de distribución. El hecho de tener la menor presión posible, permite reducir el timbraje de la tubería y las pérdidas de agua o fluido por fugas o pequeñas roturas de la red de abastecimiento. La técnica actual tiende a minimizar el tiempo de presión elevada y ajustar siempre a la mínima presión necesaria para cada caso de caudal demandado. A mayor caudal demandado, se necesita mayor presión, y por el contrario a menor caudal demandado se necesita menor presión. BACKGROUND OF THE INVENTION In the state of the art, pressure reducing valves are used to reduce the pressure to the minimum necessary within the distribution network in order to allow the supply of water or fluid to the highest disadvantaged elevation point of the network. of distribution. The fact of having the lowest possible pressure allows reducing the ringing of the pipe and the loss of water or fluid due to leaks or small breaks in the supply network. The current technique tends to minimize the high pressure time and always adjust to the minimum pressure necessary for each case of demand flow. At higher demand flow, more pressure is needed, and on the contrary at lower demand flow less pressure is needed.
Por ello, surgió la necesidad de poder controlar la presión de las válvulas reductoras, empleándose unos pilotos con regulación variable mediante diferente compresión de un muelle y que actúa directamente sobre las válvulas reductoras. Therefore, the need arose to be able to control the pressure of the reducing valves, using pilots with variable regulation by different compression of a spring and acting directly on the reducing valves.
El piloto es realmente una pequeña válvula reductora de presión y la válvula pilotada, es decir, controlada por el piloto, sólo modifica su posición en función de la apertura del piloto. Con este sistema de control diferido se puede regular presión en reductoras de grandes diámetros con la precisión del piloto. The pilot is really a small pressure reducing valve and the piloted valve, that is, controlled by the pilot, only modifies its position depending on the pilot's opening. With this deferred control system, pressure can be regulated on large diameter reducers with the precision of the pilot.
En las válvulas de control hidráulicas controladas por presión mediante un piloto, es dicho piloto el que establece una presión de consigna sobre la válvula de control, por lo tanto se habla de válvulas pilotadas. In pressure controlled hydraulic control valves by means of a pilot, it is said pilot that establishes a setpoint pressure on the control valve, therefore it is referred to as piloted valves.
La presión de consigna sobre las válvulas se puede cambiar de manera automática mediante una instalación de tuberías conectadas con los conductos de entrada y salida del piloto a controlar, que a su vez puede cambiar su consigna mediante un actuador. The setpoint pressure on the valves can be changed automatically by means of an installation of pipes connected with the inlet and outlet ducts of the pilot to be controlled, which in turn can change its setpoint by means of an actuator.
En la actualidad existen diferentes modos de establecer una presión de consigna en los pilotos como: Currently there are different ways to establish a setpoint pressure in pilots such as:
- Electroválvulas que actúan sobre una cámara que incide sobre un empujador como la descrita en la patente GB 2340205 A.  - Solenoid valves that act on a chamber that has an impact on a pusher as described in GB 2340205 A.
- Actuadores de multivuelta que actúan sobre un piloto. - Sistemas de leva y palanca que actúan sobre un piloto como el descrito en la patente WO2010097734 A. - Multiturn actuators acting on a pilot. - Cam and lever systems that act on a pilot as described in WO2010097734 A.
Dichos sistemas como el empleo de electroválvulas o sistemas de levas y palancas presentan aspectos susceptibles de ser mejorados, utilizando medios más precisos y económicos para establecer una presión de consigna en los pilotos, basados en motores eléctricos lineales que actúan sobre el piloto, desarrollando un dispositivo de presión de consigna con un actuador electromecánico, como el que a continuación se describe y queda recogido en su esencialidad en la reivindicación primera. Such systems such as the use of solenoid valves or cam and lever systems have aspects that can be improved, using more precise and economical means to establish a setpoint pressure in the pilots, based on linear electric motors acting on the pilot, developing a device of setpoint pressure with an electromechanical actuator, such as the one described below and is included in its essentiality in the first claim.

In a first proposed embodiment, it is achieved by means of a ball screw that transforms the actuator pusher into a rotational movement in a linear motion, which transmits it to the pilot's thrust plate.
En una segunda forma de realización, dicho adaptador comprende una palanca que en un extremo está unida de manera articular mediante un eje sobre un soporte fijado al piloto y en su otro extremo unido por medio de una ranura oblonga en cuyo interior se aloja un punto de unión del empujador o eje; contando dicha palanca con un punto intermedio de unión con un segundo empujador que transmite un desplazamiento lineal al platillo de empuje del piloto. In a second embodiment, said adapter comprises a lever that at one end is articularly connected by means of an axis on a support fixed to the pilot and at its other end joined by means of an oblong groove inside which a point of pusher or shaft joint; said lever having an intermediate point of attachment with a second pusher that transmits a linear displacement to the pilot's thrust plate.
Esta realización puede ser también mediante apoyo del actuador sobre la palanca y apoyo de la palanca sobre el empujador que actúa en el piloto, todo ello sin ranuras. This embodiment can also be by means of actuator support on the lever and support of the lever on the pusher acting on the pilot, all without slots.
