Las v\u00e1lvulas de control de presi\u00f3n diferencial, tambi\u00e9n llamadas com\u00fanmente DPCV, se instalan en sistemas de calefacci\u00f3n o refrigeraci\u00f3n para controlar la presi\u00f3n del subcircuito a un m\u00e1ximo establecido o determinado.<\/p>\n\n\n\n
Extremadamente eficiente, el DPCV est\u00e1 configurado a una presi\u00f3n diferencial m\u00e1xima que garantiza que el flujo no pueda exceder la tasa deseada. Por tanto, ayuda a reducir el consumo energ\u00e9tico y el riesgo de ruido y simplifica el proceso de puesta en marcha.<\/p>\n\n\n\n
La gama ZECO DPCV incluye tres tipos diferentes. Un tipo con \u0394pC (presi\u00f3n diferencial en todo el circuito) preestablecido, un tipo con \u0394pC ajustable y, finalmente, un tipo que es una v\u00e1lvula de equilibrio din\u00e1mico combinada y DPCV ajustable. Ofrecen una gama flexible que satisface cualquier demanda del sistema.<\/p>\n\n\n

<\/figure>\n<\/div>\n\n\nPrincipio de funcionamiento de la v\u00e1lvula de control de presi\u00f3n diferencial<\/h2>\n\n\n\n
La v\u00e1lvula de control de presi\u00f3n diferencial no necesita energ\u00eda externa. Puede ajustarse autom\u00e1ticamente bas\u00e1ndose en el cambio de presi\u00f3n del propio medio regulado, eliminar autom\u00e1ticamente el cambio de flujo causado por la presi\u00f3n residual y la fluctuaci\u00f3n de presi\u00f3n de la red de tuber\u00edas, y mantener constante la diferencia de presi\u00f3n entre la entrada y la salida del usuario. Es especialmente adecuado para sistemas de medici\u00f3n o control autom\u00e1tico dom\u00e9sticos, lo que favorece un funcionamiento estable del sistema.<\/p>\n\n\n\n
La v\u00e1lvula de control de presi\u00f3n diferencial tiene una estructura de doble disco, con una peque\u00f1a fuerza desequilibrada y una estructura compacta. Se utiliza en el sistema de agua de calefacci\u00f3n (aire acondicionado) para mantener constante la presi\u00f3n diferencial del sistema controlado. De acuerdo con el principio de funcionamiento de la v\u00e1lvula de control de presi\u00f3n diferencial, los usuarios que instalan la v\u00e1lvula de control de presi\u00f3n diferencial no instalan el dispositivo de control autom\u00e1tico. Bajo la diferencia m\u00ednima de presi\u00f3n de trabajo, cuando el di\u00e1metro de la tuber\u00eda seleccionada es demasiado grande y se reduce la resistencia, el flujo ser\u00e1 demasiado grande, lo que inevitablemente provocar\u00e1 el desequilibrio hidr\u00e1ulico de la red externa y aumentar\u00e1 el consumo de energ\u00eda.<\/p>\n\n\n\n
La v\u00e1lvula de control de presi\u00f3n diferencial se compone del cuerpo de la v\u00e1lvula, la tapa de la v\u00e1lvula, el resorte del n\u00facleo de la v\u00e1lvula, el conducto de control y el regulador de presi\u00f3n.<\/p>\n\n\n\n
La v\u00e1lvula se instala en la tuber\u00eda de retorno de la tuber\u00eda de calefacci\u00f3n y la c\u00e1mara de trabajo de la v\u00e1lvula se conecta con la tuber\u00eda de suministro de agua a trav\u00e9s de la tuber\u00eda de control. Eliminar la desviaci\u00f3n de flujo provocada por la fluctuaci\u00f3n de presi\u00f3n de la red externa. Cuando aumenta la presi\u00f3n del suministro de agua P1, aumenta la diferencia de presi\u00f3n del suministro de agua P1-P3. La membrana sensora de presi\u00f3n impulsa el n\u00facleo de la v\u00e1lvula hacia abajo para cerrar el puerto peque\u00f1o de la v\u00e1lvula, de modo que P2 aumenta, manteniendo as\u00ed el P1-P2 constante. Cuando la presi\u00f3n del suministro de agua P1 disminuye, la membrana sensora de presi\u00f3n hace que el n\u00facleo de la v\u00e1lvula se mueva hacia arriba y P2 disminuye, de modo que P1-P2 es constante. No importa c\u00f3mo cambie la presi\u00f3n en la tuber\u00eda, la v\u00e1lvula de equilibrio de presi\u00f3n diferencial din\u00e1mica puede mantener la presi\u00f3n y el flujo constantes aplicados al objeto controlado.<\/p>\n\n\n\n
Principio de funcionamiento de la v\u00e1lvula de control de presi\u00f3n diferencial autoaccionada<\/h2>\n\n\n\n
Despu\u00e9s de que la v\u00e1lvula estrangula el medio del proceso, ingresa al equipo controlado y la presi\u00f3n diferencial del equipo controlado se introduce respectivamente en las c\u00e1maras de membrana superior e inferior de la v\u00e1lvula, generando empuje en las c\u00e1maras de membrana superior e inferior y equilibrando. con la fuerza de reacci\u00f3n del resorte, para determinar la posici\u00f3n relativa del n\u00facleo de la v\u00e1lvula y el asiento de la v\u00e1lvula, mientras que la posici\u00f3n relativa del n\u00facleo de la v\u00e1lvula y el asiento de la v\u00e1lvula determina el tama\u00f1o del valor de presi\u00f3n diferencial. Cuando la presi\u00f3n diferencial controlada cambia, se destruye el equilibrio de la fuerza que impulsa el movimiento del n\u00facleo de la v\u00e1lvula, y el movimiento del n\u00facleo de la v\u00e1lvula cambia el coeficiente de resistencia de la v\u00e1lvula, es decir, el valor de la presi\u00f3n diferencial controlada se controla como el valor establecido. Este es el principio de funcionamiento de la v\u00e1lvula de control de presi\u00f3n diferencial. Cuando es necesario cambiar el valor de ajuste de la presi\u00f3n diferencial, se puede ajustar la tuerca de ajuste.<\/p>\n\n\n\n\n
