Cuando se gira el volante en el sentido de las agujas del reloj, la rosca del v\u00e1stago se atornilla, la superficie de sellado del disco est\u00e1 en estrecho contacto con el asiento de la v\u00e1lvula y la v\u00e1lvula de globo se cierra. Cuando se gira el volante en sentido antihorario, se enrosca la rosca del v\u00e1stago, se separa la superficie de sellado del disco y el asiento de la v\u00e1lvula y se abre la v\u00e1lvula de globo.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Caracter\u00edsticas de la v\u00e1lvula de globo.<\/h2>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>Ventajas<\/strong> de v\u00e1lvula de globo<\/h3>\n\n\n\n<p>a.En comparaci\u00f3n con el\u00a0<a href=\"https:\/\/zecovalve.com\/es\/products\/valvula-de-compuerta\/\">v\u00e1lvula de compuerta<\/a>, la v\u00e1lvula de globo tiene una estructura simple con una sola superficie de sellado en el cuerpo de la v\u00e1lvula y el disco. El \u00e1rea de sellado es peque\u00f1a, no se utilizan materiales costosos y tiene un costo bajo, por lo que el proceso de fabricaci\u00f3n es relativamente bueno y su mantenimiento es sencillo.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>Desventajas<\/strong> de v\u00e1lvula de globo<\/h3>\n\n\n\n<ul class=\"wp-block-list\"><li>a. La longitud de la estructura es grande.<\/li><li>b.El par de apertura y cierre es grande y lleva tiempo abrir y cerrar. Cuando la v\u00e1lvula est\u00e1 cerrada, la direcci\u00f3n del movimiento del disco es opuesta a la direcci\u00f3n de acci\u00f3n de la presi\u00f3n del medio y se debe superar la fuerza del medio, por lo que el par de apertura y cierre es grande.<\/li><li>c.La resistencia al flujo es grande. El canal medio en el cuerpo de la v\u00e1lvula es tortuoso, la resistencia al flujo es grande y el consumo de energ\u00eda es grande. En el dispositivo hidr\u00e1ulico, la p\u00e9rdida de presi\u00f3n es particularmente evidente. Entre todos los tipos de v\u00e1lvulas de bloqueo, la v\u00e1lvula de bloqueo tiene la mayor resistencia al flujo.<\/li><li>d. La direcci\u00f3n del flujo del medio es limitada. Cuando el medio fluye a trav\u00e9s de la v\u00e1lvula de globo, solo puede fluir de abajo hacia arriba o de arriba hacia abajo en el canal del asiento de la v\u00e1lvula, por lo que el medio solo puede fluir en una direcci\u00f3n y no puede cambiar la direcci\u00f3n del flujo.<\/li><li>e. Cuando la v\u00e1lvula est\u00e1 cerrada, las part\u00edculas s\u00f3lidas del medio fluido pueden quedar atrapadas entre las superficies de sellado.<\/li><li>F.

Cuando la v\u00e1lvula est\u00e1 cerrada, se debe aplicar fuerza suficiente al disco de la v\u00e1lvula para lograr el efecto de sellado, y el sellado solo se puede realizar cuando la presi\u00f3n espec\u00edfica es suficiente.<\/p>\n\n\n\n<p>La fuerza de sellado y la presi\u00f3n media est\u00e1n en el mismo eje. Cuando el medio ingresa desde la parte inferior del disco de la v\u00e1lvula (hacia adentro y hacia afuera), el par de cierre de la v\u00e1lvula es mayor que el par de apertura debido a la direcci\u00f3n opuesta de la presi\u00f3n del medio y la fuerza de sellado, y la tensi\u00f3n m\u00e1xima En el v\u00e1stago de la v\u00e1lvula est\u00e1 la tensi\u00f3n de presi\u00f3n, por lo que debe haber suficiente resistencia y rigidez, de lo contrario el v\u00e1stago de la v\u00e1lvula se deformar\u00e1.<\/p>\n\n\n\n<p>Por lo tanto, cuando el tama\u00f1o de la v\u00e1lvula de globo es mayor que DN150 (NPS 6), para reducir el par de operaci\u00f3n de la v\u00e1lvula y reducir el di\u00e1metro del v\u00e1stago de la v\u00e1lvula, el medio generalmente fluye hacia la parte superior del disco de la v\u00e1lvula. para entrar (alto adentro y bajo afuera). En este momento, la direcci\u00f3n de la presi\u00f3n media y la fuerza de sellado es la misma. Bajo la acci\u00f3n de una presi\u00f3n media, la v\u00e1lvula se puede sellar m\u00e1s f\u00e1cilmente. El par de cierre disminuye y el par de apertura aumenta, la tensi\u00f3n m\u00e1xima sobre el v\u00e1stago de la v\u00e1lvula es la tensi\u00f3n de tracci\u00f3n y el di\u00e1metro del v\u00e1stago de la v\u00e1lvula se puede reducir en consecuencia.<\/p>\n\n\n\n<p>Cuando se abre la v\u00e1lvula de globo, cuando la altura de apertura del disco alcanza 25-30% del tama\u00f1o nominal de la v\u00e1lvula, el flujo ha alcanzado el m\u00e1ximo, es decir, la v\u00e1lvula ha alcanzado la posici\u00f3n completamente abierta, por lo que la posici\u00f3n completamente abierta de la v\u00e1lvula de globo debe determinarse seg\u00fan la carrera del disco.<\/p>\n\n\n\n<p>Cuando la v\u00e1lvula de globo se cierra y se vuelve a abrir, es similar a la v\u00e1lvula de compuerta de sellado forzado, es decir, despu\u00e9s de cerrar la v\u00e1lvula, se debe aplicar suficiente fuerza operativa en la superficie de sellado para lograr el efecto de sellado. Por lo tanto, el par de cierre de la v\u00e1lvula debe aumentarse al valor especificado en funci\u00f3n del par de funcionamiento. Cuando la v\u00e1lvula se abre nuevamente, el par de apertura de la v\u00e1lvula suele ser mayor que el par de cierre debido a la influencia de la fricci\u00f3n est\u00e1tica, la expansi\u00f3n t\u00e9rmica y otros factores, por lo que la v\u00e1lvula se puede abrir de manera confiable y debe considerarse en el dise\u00f1o.<\/p>\n\n\n\n<p>Para reducir la alta presi\u00f3n de impacto formada en la v\u00e1lvula de apertura y cierre, la v\u00e1lvula de globo debe operarse lentamente; en cierto sentido, debe tener una tasa de cambio consistente con el caudal.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">El par de funcionamiento de la v\u00e1lvula de globo tiene las siguientes caracter\u00edsticas:<\/h2>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>\u201cAberturas de entrada bajas y salidas altas\u201d<\/strong><\/h3>\n\n\n\n<p>Cuando se adopta \u201centrada baja y salida alta\u201d, la v\u00e1lvula se cierra desde la posici\u00f3n completamente abierta. La resistencia que debe superar la fuerza operativa es la resistencia a la fricci\u00f3n del v\u00e1stago y la empaquetadura y el empuje provocado por la presi\u00f3n media sobre la secci\u00f3n del disco (axial). Con la ca\u00edda del disco de la v\u00e1lvula, se forma la diferencia de presi\u00f3n entre la parte delantera y trasera del disco de la v\u00e1lvula, lo que evita que el disco de la v\u00e1lvula caiga, y la resistencia aumentar\u00e1 r\u00e1pidamente con la ca\u00edda del disco de la v\u00e1lvula. Con la v\u00e1lvula completamente cerrada, el v\u00e1stago de la v\u00e1lvula aplica una fuerza de sellado forzada y la diferencia de presi\u00f3n entre la parte delantera y trasera del disco de la v\u00e1lvula alcanza la presi\u00f3n m\u00e1xima de trabajo del medio; en este momento, el v\u00e1stago de la v\u00e1lvula soporta la m\u00e1xima par de cierre.<\/p>\n\n\n\n<p>Durante la apertura de la v\u00e1lvula, la presi\u00f3n media o el empuje causado por la diferencia de presi\u00f3n entre la parte delantera y trasera del disco es la misma que la direcci\u00f3n de cierre de la v\u00e1lvula. Sin embargo, cabe se\u00f1alar que en el momento de la apertura, el par de operaci\u00f3n de apertura puede exceder el par de cierre debido al gran par de fricci\u00f3n est\u00e1tica entre las superficies de sellado.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>\u201cAberturas de entrada altas y salida bajas\u201d<\/strong><\/h3>\n\n\n\n<p>Cuando se adopta \u201centrada alta y salida baja\u201d, la v\u00e1lvula se cierra desde la posici\u00f3n completamente abierta. Las dos fuerzas anteriores todav\u00eda son necesarias para superar la fuerza operativa. Con la disminuci\u00f3n del disco de la v\u00e1lvula, la diferencia de presi\u00f3n antes y despu\u00e9s del disco de la v\u00e1lvula conduce al cierre de la v\u00e1lvula antes de que se cierre la v\u00e1lvula.<\/p>\n\n\n\n<p>Cuando se abre la v\u00e1lvula, la situaci\u00f3n es todo lo contrario. El empuje causado por la presi\u00f3n del medio y la diferencia de presi\u00f3n entre la parte delantera y trasera del disco es opuesto a la direcci\u00f3n de apertura de la v\u00e1lvula, por lo que el par de operaci\u00f3n requerido para el proceso de apertura de la v\u00e1lvula es mucho mayor que el par de cierre.<\/p>\n\n\n\n<!-- Andy:h-related-tags -->\n<h2 id=\"h-related-tags\">Etiquetas relacionadas :<\/h2>\n<!-- \/Andy:h-related-tags -->\n\n\n\n<div class=\"re_main\">\n<a href=\"https:\/\/zecovalve.com\/es\/\">V\u00e1lvula ZECO<\/a>\n\n<\/div>\n\n\n\n<div class=\"re_main\">\n<a href=\"https:\/\/zecovalve.com\/es\/introduction-of-epdm-nbr-butterfly-valve-seat-industrial-valve-information-news-zeco-valve.html\/\">V\u00e1lvula de mariposa de NBR<\/a>\n\n<\/div>\n\n\n\n<div class=\"re_main\">\n<a href=\"https:\/\/zecovalve.com\/es\/difference-between-gate-valves-and-ball-valves.html\/\">V\u00e1lvula de compuerta frente a v\u00e1lvula de bola<\/a>\n\n<\/div>\n\n\n\n<div class=\"re_main\">\n<a href=\"https:\/\/zecovalve.com\/es\/gate-valve-problems.html\/\">Reparaci\u00f3n de v\u00e1lvulas de compuerta<\/a>\n\n<\/div>\n\n\n\n<div class=\"re_main\">\n<a href=\"https:\/\/zecovalve.com\/es\/advantages-and-disadvantages-of-globe-valves.html\/\">\u00bfQu\u00e9 es una v\u00e1lvula de globo?<\/a>\n\n<\/div>\n\n\n\n<div class=\"re_main\">\n<a href=\"https:\/\/zecovalve.com\/es\/the-function-of-globe-valve-in-pipeline-system.html\/\">\u00bfQu\u00e9 son las v\u00e1lvulas de globo?<\/a>\n\n<\/div>\n\n\n\n<div class=\"re_main\">\n<a href=\"https:\/\/zecovalve.com\/es\/producto\/manual-gate-valve\/\">v\u00e1lvula de compuerta de accionamiento manual Fabricantes<\/a>\n\n<\/div>\n\n\n\n<div class=\"re_main\">\n<a href=\"https:\/\/zecovalve.com\/es\/what-is-an-axial-flow-silent-check-valve.html\/\">Qu\u00e9 es una v\u00e1lvula antirretorno axial<\/a>\n\n<\/div>\n\n\n\n\n<div class=\"re_main\">\n<a href=\"https:\/\/zecovalve.com\/es\/difference-between-gate-valve-and-butterfly-valve.html\/\">Diferencia entre v\u00e1lvula de compuerta y v\u00e1lvula de mariposa<\/a>\n\n<\/div>\n\n\n\n<div class=\"re_main\">\n<a href=\"https:\/\/zecovalve.com\/es\/china-gate-valves-suppliersnon-rising-stem-gate-valvesks-gate-valves.html\/\">\u00bfQu\u00e9 es una v\u00e1lvula de compuerta?<\/a>\n\n<\/div>\n\n\n\n<div class=\"re_main\">\n<a href=\"https:\/\/zecovalve.com\/es\/tag\/shanghai-pressure-reducing-valve-factory\/\">F\u00e1brica de v\u00e1lvulas reductoras de presi\u00f3n de Shanghai<\/a>\n\n<\/div>","protected":false},"excerpt":{"rendered":"<p>La v\u00e1lvula de globo, tambi\u00e9n llamada v\u00e1lvula de cierre, es una de las v\u00e1lvulas m\u00e1s utilizadas.

And with their ability to start, stop, and throttle fluid flow within a pipeline, it\u2019s easy to see why.\r\n\r\n<!-- \/wp:paragraph -->\r\n\r\n<!-- wp:paragraph -->\r\n\r\nGenerally speaking, the flow of globe vales is from down to up. It means the medium will go through from the disc downside and then out by the upside. Globe valves usually adopt a compulsory sealed design, so closing the valve offer pressure to the disc against the seat. So if you want to open the valve, the globe valve disc must overcome resistance made by stem and packing friction, medium pressure will offer adverse pressure which helps open the valve. It means you can use less force than the closing valve. So the stem diameter should be larger, to avoid stem bending fault. (depending on the metal material's physical performance of the stem ). In recent years, there are more and more valve pressure seals, the medium through the upper disc to the down disc, so the close valve force is smaller than the open valve force, valve shaft diameter is allowed to be smaller.\r\n\r\n<!-- \/wp:paragraph -->\r\n\r\n<!-- wp:paragraph -->\r\n\r\nBut some opinions disagree with it, especially for a globe valve with a larger size (for example, a size bigger than DN250), the globe valve usually adopts a valve pressure seal, and considering closing valve force, it is easy to reach the seal performance. But it should take the stabilization of the valve into consideration when the valve stem diameter is smaller than the seat diameter.\r\n\r\n<!-- \/wp:paragraph -->\r\n\r\n<!-- wp:paragraph -->\r\n\r\nBut how exactly do these valves work and what\u2019s the globe valve direction flow?\r\n\r\n<!-- \/wp:paragraph -->\r\n\r\n<!-- wp:heading -->\r\n<h2>How do Globe Valves Work?<\/h2>\r\n<!-- \/wp:heading -->\r\n\r\n<!-- wp:paragraph -->\r\n\r\nA globe valve is primarily designed to stop, start and regulate flow. It is comprised of a movable disk and a stationary ring seat in a generally spherical body. The seat of a globe valve is in the middle of and parallel to the pipe, and the opening in the seat is closed off with the disk. When the handle is turned, manually or through an actuator, a disc is lowered or raised by means of the valve stem. When the disc is fully lowered, the fluid flow is shut off. When the disc is fully raised, the fluid flow is at its maximum rate. When the disc is raised to the less than maximum level, the fluid flow is regulated in proportion to the vertical travel of the disc.\r\n\r\n<!-- \/wp:paragraph -->\r\n\r\n<!-- wp:heading -->\r\n<h2 id=\"h-globe-valve-flow-direction\"><strong>Globe Valve Flow Direction<\/strong><\/h2>\r\n<!-- \/wp:heading -->\r\n\r\n<!-- wp:paragraph -->\r\n\r\n-For low-temperature applications, globe and angle valves are ordinarily installed so that pressure under the disk. This promotes easy operation, helps protect the packing, and eliminates a certain amount of erosive action to the seat and disk faces.\r\n\r\n<!-- \/wp:paragraph -->\r\n\r\n<!-- wp:paragraph -->\r\n\r\n-For high-temperature steam service, globe valves are installed so that pressure is above the disk. Otherwise, the stem will contract upon cooling and tend to lift the disk off the seat ( and leak).\r\n\r\n<!-- \/wp:paragraph -->\r\n\r\n<!-- wp:heading {\"level\":3} -->\r\n<h3>Flow to Open (FTO)<\/h3>\r\n<!-- \/wp:heading -->\r\n\r\n<!-- wp:paragraph -->\r\n\r\nAlso referred to as standard or forward flow, or in globe valves, flow under the seat. Think about when you've controlled the flow of water from a garden hose with your thumb. Your thumb acts like the face of the plug in a globe valve - flow is pushing against your thumb to open a flow path for the water.\r\n\r\n<!-- \/wp:paragraph -->\r\n\r\n<!-- wp:heading {\"level\":3} -->\r\n<h3>Flow to Close (FTC)<\/h3>\r\n<!-- \/wp:heading -->\r\n\r\n<!-- wp:paragraph -->\r\n\r\nAlso referred to as reverse flow or in globe valves, flow over the seat. Consider a drain plug in a bathtub. The flow direction is against the back or top of the plug (rather than the face) creating a tendency for the plug to close into the drain.\r\n\r\n<!-- \/wp:paragraph -->\r\n\r\n<!-- wp:image {\"align\":\"center\",\"id\":27401,\"width\":376,\"height\":387,\"sizeSlug\":\"full\",\"linkDestination\":\"none\"} -->\r\n<figure class=\"wp-block-image aligncenter size-full is-resized\"><img class=\"wp-image-27401\" src=\"https:\/\/zecovalve.com\/wp-content\/uploads\/2023\/02\/GLOBE-VALVE-FTO-FTC.png\" alt=\"\" width=\"376\" height=\"387\" \/><\/figure>\r\n<!-- \/wp:image -->\r\n\r\n<!-- wp:paragraph -->\r\n\r\n<!-- \/wp:paragraph -->\r\n\r\n<!-- wp:paragraph -->\r\n\r\n<!-- \/wp:paragraph -->","parent":0,"count":8,"filter":"raw"},{"term_id":2321,"name":"working principle of globe valve","slug":"working-principle-of-globe-valve","term_group":0,"term_taxonomy_id":2321,"taxonomy":"post_tag","description":"","parent":0,"count":1,"filter":"raw"}],"taxonomy_info":{"category":[{"value":1929,"label":"Globe Valve"}],"post_tag":[{"value":1894,"label":"Advantages and Disadvantages of Globe Valves"},{"value":1811,"label":"advantages of globe valve"},{"value":1973,"label":"China Angle Globe Valve"},{"value":1812,"label":"disadvantages of globe valve"},{"value":2320,"label":"features of globe valve"},{"value":1805,"label":"globe valve"},{"value":3671,"label":"Globe Valve Flow Direction"},{"value":2321,"label":"working principle of globe valve"}]},"yoast_head":"<!-- This site is optimized with the Yoast SEO Premium plugin v15.4 - https:\/\/yoast.com\/wordpress\/plugins\/seo\/ -->\n<title>Introduction of Globe Valve - ZECO Valve<\/title>\n<meta name=\"robots\" content=\"index, follow, max-snippet:-1, max-image-preview:large, max-video-preview:-1\" \/>\n<link rel=\"canonical\" href=\"https:\/\/zecovalve.com\/es\/introduction-of-globe-valve.html\" \/>\n<meta property=\"og:locale\" content=\"es_ES\" \/>\n<meta property=\"og:type\" content=\"article\" \/>\n<meta property=\"og:title\" content=\"Introduction of Globe Valve - ZECO Valve\" \/>\n<meta property=\"og:description\" content=\"Globe valve, also called stop valve, is one of the most widely used valves.
