Tem sido amplamente utilizado em petr\u00f3leo, ind\u00fastria qu\u00edmica, metalurgia, energia hidrel\u00e9trica e muitos outros campos. Entre as v\u00e1lvulas borboleta el\u00e9tricas comumente utilizadas, elas s\u00e3o divididas principalmente em v\u00e1lvulas borboleta de fixa\u00e7\u00e3o el\u00e9trica e v\u00e1lvulas borboleta de flange el\u00e9trica, que possuem caracter\u00edsticas pr\u00f3prias e desempenhos diferenciados, podendo ser utilizadas em diversos setores. Para esses dois tipos de v\u00e1lvulas, al\u00e9m da forma estrutural, se forem utilizados os mesmos par\u00e2metros, a maior diferen\u00e7a \u00e9 que a conex\u00e3o \u00e9 diferente, ou seja, a forma de instala\u00e7\u00e3o precisa depender das condi\u00e7\u00f5es de trabalho!<\/p>\n\n\n\n\n\n<h2 class=\"wp-block-heading\" id=\"h-the-difference-between-electric-wafer-butterfly-valve-and-electric-flange-butterfly-valve\">A diferen\u00e7a entre a v\u00e1lvula borboleta wafer el\u00e9trica e a v\u00e1lvula borboleta flangeada el\u00e9trica:<\/h2>\n\n\n\n<p>A espessura da v\u00e1lvula borboleta wafer el\u00e9trica \u00e9 mais fina do que a da v\u00e1lvula borboleta flangeada. N\u00e3o h\u00e1 flanges em ambas as extremidades do corpo da v\u00e1lvula e apenas alguns furos para parafusos guia. A v\u00e1lvula \u00e9 conectada ao flange na extremidade do tubo atrav\u00e9s de um conjunto de parafusos\/porcas. \u00c9 um local onde o espa\u00e7o \u00e9 relativamente estreito ou onde os tubos s\u00e3o limitados. As vantagens s\u00e3o f\u00e1cil desmontagem, baixo custo das v\u00e1lvulas e pequena ocupa\u00e7\u00e3o de espa\u00e7o, mas a desvantagem \u00e9 que h\u00e1 problema na superf\u00edcie de veda\u00e7\u00e3o, portanto duas superf\u00edcies de veda\u00e7\u00e3o devem ser removidas.<\/p>\n\n\n\n<p>O corpo da v\u00e1lvula borboleta com flange el\u00e9trico possui flanges em ambas as extremidades e \u00e9 conectado a flanges de tubo. O desempenho da veda\u00e7\u00e3o \u00e9 mais confi\u00e1vel do que a v\u00e1lvula borboleta wafer. Geralmente \u00e9 usado em \u00e1reas de grande calibre ou alta press\u00e3o, mas o custo \u00e9 relativamente alto. As v\u00e1lvulas borboleta el\u00e9tricas custam muito.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">No entanto, ainda existem alguns assuntos que precisam de aten\u00e7\u00e3o no design. <\/h2>\n\n\n\n<p>Por exemplo, os parafusos das v\u00e1lvulas s\u00e3o geralmente muito longos. Sob alta temperatura, a expans\u00e3o do parafuso pode causar vazamento, por isso n\u00e3o \u00e9 adequado para grandes di\u00e2metros em alta temperatura. Por exemplo, v\u00e1lvulas borboleta de fixa\u00e7\u00e3o n\u00e3o podem ser utilizadas no final da tubula\u00e7\u00e3o, e a jusante precisa ser desmontada, pois quando o flange a jusante for removido a v\u00e1lvula de fixa\u00e7\u00e3o cair\u00e1, que deve ser muito curta. Embora a v\u00e1lvula borboleta flangeada n\u00e3o apresente os problemas acima, o custo ser\u00e1 relativamente maior.<br><br>Como um dos principais fabricantes de v\u00e1lvulas borboleta wafer na China, a ZECO Valve est\u00e1 comprometida em fabricar v\u00e1lvulas borboleta wafer de alta qualidade.

-->\r\n\r\n<!-- wp:paragraph -->\r\n\r\nWith Centerline Butterfly Valves only two parts of the valve come in contact with the medium. This means that neither the body nor mechanical parts such as the shaft are exposed to the corrosive environment.\r\n\r\n<!-- \/wp:paragraph -->\r\n\r\n<!-- wp:paragraph -->\r\n\r\nThe only two parts in contact with the medium are the body lining and the disc.

The disc presses with uniform compression into the elastic cartridge seat over the entire circumference of the valve.\r\n\r\n<!-- \/wp:paragraph -->\r\n\r\n<!-- wp:heading {\"level\":3} -->\r\n<h3>Replaceable Seat<\/h3>\r\n<!-- \/wp:heading -->\r\n\r\n<!-- wp:paragraph -->\r\n\r\nThe replaceable seat consists of a reinforced backup ring, on which the elastomer seat material is vulcanized. When mounting the valve between the pipe flanges this stable seat cannot be deformed or displaced. The cartridge design also prevents deformation when the valve is cycled, such as stretching and bulging of the elastomer in front of the moving disc.\r\n\r\n<!-- \/wp:paragraph -->\r\n\r\n<!-- wp:paragraph -->\r\n\r\nThe fixed connection between the elastomer and the backup ring allows the use of the valve in a full vacuum and high flow velocities.
