Triple Versus de V\u00e1lvulas<\/h2>\n\n\n\n

Manual VS Autom\u00e1tica VS Termost\u00e1tica<\/span><\/h3>\n\n\n\n

V\u00e1lvulas de expansi\u00f3n en Torrington Refrigerantes<\/a><\/em><\/strong><\/p>\n\n\n\n

Toda v\u00e1lvula es empleada para regular el caudal de fluido refrigerante dentro del circuito. Hoy te invitamos a conocer este versus de v\u00e1lvulas de expansi\u00f3n.<\/em><\/strong><\/p>\n\n\n\n

Las v\u00e1lvulas de expansi\u00f3n de tipo manuales<\/span><\/h3>\n\n\n\n
\"Comparamos
V\u00e1lvula de expansi\u00f3n manual<\/strong><\/figcaption><\/figure><\/div>\n\n\n\n

Son utilizadas como v\u00e1lvulas auxiliares de regulaci\u00f3n de flujo del refrigerante, instal\u00e1ndose en una tuber\u00eda de desviaci\u00f3n. Son v\u00e1lvulas de aguja, operadas manualmente. El caudal de paso por la v\u00e1lvula depende del grado de apertura de la v\u00e1lvula y del diferencial de presi\u00f3n a trav\u00e9s del orificio de la misma.<\/p>\n\n\n\n

Las v\u00e1lvulas de expansi\u00f3n autom\u00e1ticas: AEV o AXV<\/span><\/h3>\n\n\n\n
\"Comparamos
V\u00e1lvula de expansi\u00f3n autom\u00e1tica<\/strong><\/figcaption><\/figure><\/div>\n\n\n\n

Mantienen una presi\u00f3n constante en el evaporador, inundando \u00e9ste m\u00e1s o menos, como respuesta a la carga frigor\u00edfica solicitada. La presi\u00f3n constante, caracter\u00edstica de la v\u00e1lvula, resulta de la interacci\u00f3n de dos fuerzas opuestas, es decir la presi\u00f3n de evaporaci\u00f3n y la del muelle.<\/p>\n\n\n\n

Las v\u00e1lvulas de expansi\u00f3n termost\u00e1ticas: VET<\/span><\/h3>\n\n\n\n

<\/p>\n\n\n\n

Debido a sus grandes ventajas y a su f\u00e1cil instalaci\u00f3n, esta v\u00e1lvula es quiz\u00e1 la m\u00e1s utilizada en sistemas frigor\u00edficos. Asegura que el vapor que se va formando en el evaporador se sobrecalienta hasta cierto nivel controlado. Esto permite mantener el evaporador completamente lleno de refrigerante bajo las condiciones de carga del sistema, sin peligro de paso de l\u00edquido a la tuber\u00eda de aspiraci\u00f3n. La denominaci\u00f3n “termost\u00e1tica” puede prestarse a error, puesto que el control no se hace por la temperatura del evaporador, sino por el grado de recalentamiento del gas de admisi\u00f3n que sale del evaporador.<\/p>\n\n\n\n

Hablando de v\u00e1lvulas…<\/h3>\n\n\n\n

\u00bfConoc\u00e9s a las v\u00e1lvulas pinche?<\/h4>\n\n\n\n

La v\u00e1lvula pinche nos permite realizar cargas o descargas de fluido refrigerante sin necesidad de cortar y soldar ca\u00f1os. Se utilizan tambi\u00e9n, para verificar si los equipos a diagn\u00f3sticar, tienen carga de refrigerante.<\/p>\n\n\n\n

Las nuevas v\u00e1lvulas pinches no son reutilizables, puesto que quedan como un ap\u00e9ndice de acceso a la ca\u00f1eria. Son de instalaci\u00f3n \u00fanica.<\/p>\n\n\n\n

Algunos t\u00e9cnicos recomiendan retirarlas, para evitar posibles fugas, y luego estrangular y soldar la perforaci\u00f3n del ca\u00f1o. En este caso, se debe colocar: una v\u00e1lvula con chicote de soldar o usar un chicote largo con v\u00e1lvula, para luego cortarlo y sellarlo como viene de fabrica.<\/p>\n\n\n\n
