Inevitablemente encontraremos algunas fallas en el proceso de uso de la v\u00e1lvula de compuerta de acero fundido. \u00bfC\u00f3mo debemos afrontar estos fracasos? Hoy presentaremos las soluciones para solucionar fallas de la v\u00e1lvula de compuerta de acero fundido.<\/p>\n\n\n\n\n\n
El agrietamiento (o deformaci\u00f3n del fondo) de la v\u00e1lvula de compuerta de acero fundido aparece principalmente en los productos de estructura de placa paralela Z944\/Z964. Ocurre cuando la parte inferior de la placa de compuerta de la v\u00e1lvula de compuerta de acero fundido golpea directamente el cuerpo de la v\u00e1lvula. Adem\u00e1s, es muy f\u00e1cil que ocurra cuando la carrera de cierre no est\u00e1 configurada o falla el l\u00edmite debido a una mala puesta en funcionamiento de la electrov\u00e1lvula.<\/p>\n\n\n\n
Las grietas en la superficie de sellado se producen principalmente en v\u00e1lvulas de acero fundido hechas de acero aleado, que a menudo son causadas por procesos no razonables. Esto se puede evitar con una selecci\u00f3n razonable de materiales y un control razonable de los par\u00e1metros del proceso de soldadura.<\/p>\n\n\n\n
El atasco de la v\u00e1lvula de compuerta de acero fundido muestra que la compuerta est\u00e1 atascada en el lado del riel gu\u00eda de la cavidad central del cuerpo de la v\u00e1lvula, o incluso separada del v\u00e1stago de la v\u00e1lvula. Se debe principalmente a un dise\u00f1o y fabricaci\u00f3n deficientes, como el tama\u00f1o inadecuado del ancho de contacto del riel gu\u00eda y la superficie rugosa del riel gu\u00eda.<\/p>\n\n\n\n
Cuando la compuerta se atasca en el asiento de la v\u00e1lvula de compuerta de acero fundido y el v\u00e1stago de la v\u00e1lvula se levanta con fuerza, la ranura en forma de T de la compuerta a menudo se rompe o deforma para evitar el factor de "impulso anormal". La diferencia de temperatura y la fuerza de cierre son dos razones principales a las que vale la pena prestar atenci\u00f3n.<\/p>\n\n\n\n
Existe una condici\u00f3n operativa t\u00edpica de diferencia de temperatura. Si las v\u00e1lvulas de acero fundido se cierran en estado fr\u00edo y luego se abren en estado caliente, el par de cierre de la compuerta aumentar\u00e1 y provocar\u00e1 que la compuerta se acu\u00f1e debido a la expansi\u00f3n t\u00e9rmica y el alargamiento del v\u00e1stago de la v\u00e1lvula.<\/p>\n\n\n\n
Si se cierra el estado caliente y se abre el estado fr\u00edo, el ancho de la entrepierna aumentar\u00e1 debido a la deformaci\u00f3n t\u00e9rmica de los asientos de v\u00e1lvula en ambos lados. El estado fr\u00edo har\u00e1 que se encojan y se vuelvan m\u00e1s peque\u00f1os, lo que provocar\u00e1 que la puerta se acu\u00f1e. Si los dos estados anteriores van acompa\u00f1ados de una fuerte \u201cfuerza de cierre\u201d. Si el accionamiento el\u00e9ctrico no se ajusta correctamente o el mecanismo de refuerzo, como una llave o una palanca, se utiliza incorrectamente, existe una mayor posibilidad de que la compuerta de la v\u00e1lvula de compuerta de acero fundido se atasque.<\/p>\n\n\n\n

Forged valves do tend to be better for high-temperature and high-pressure applications. These types of valves are less prone to thermal fatigue because the walls are thinner compared to cast alternatives. Also, forged options have a higher mass, making them mechanically stronger.\r\n\r\n\r\n\r\n\r\n\r\nHowever, there are a few reasons why a forged ball valve may not be best for your application. First, the forging process does create limitations for valve size and shape. Forging generally works better for smaller valves and components. In addition, not every metal is suitable for forging, which limits your options for valve material.\r\n\r\n\r\n\r\n\r\nAdvantages and Disadvantages of Cast Valves\r\n\r\n\r\n\r\n\r\nCast valves are a great option where you need quick turnaround and low-cost valves, as they require less labor to produce. Also, the casting process allows for more complex shapes and valve manufacturing. You also have greater flexibility in material choice, as many types of metals are suitable for casting.\r\n\r\n\r\n\r\n\r\n\r\nWhile cast valves are quite strong and durable when you choose a high-quality manufacturer, there are still some restrictions. For example, the solidification process can create small impurities in the metal. They also are less resistant to high temperatures and pressures compared to a forged ball valve.\r\n\r\n","parent":0,"count":7,"filter":"raw"},{"term_id":3,"name":"gate valve","slug":"gate-valve","term_group":0,"term_taxonomy_id":3,"taxonomy":"post_tag","description":"","parent":0,"count":41,"filter":"raw"}],"taxonomy_info":{"category":[{"value":1928,"label":"Gate Valve"}],"post_tag":[{"value":2176,"label":"cast steel gate valve"},{"value":3268,"label":"Difference Between Cast and Forged"},{"value":3,"label":"gate valve"}]},"yoast_head":"\n
