V\u00e1lvula de globo de paso recto\/patr\u00f3n TEE<\/h3>\n\n\n\n
El dise\u00f1o de v\u00e1lvula en T es el tipo m\u00e1s com\u00fan de cuerpo de v\u00e1lvula, que tiene una trayectoria de flujo de entrada y salida de 180\u00b0 en la misma direcci\u00f3n y un ajuste horizontal del asiento de la v\u00e1lvula que permite que el v\u00e1stago y el disco se muevan perpendicularmente a la l\u00ednea horizontal. Este dise\u00f1o tiene un coeficiente de caudal y una ca\u00edda de presi\u00f3n bajos. Se utilizan en servicios de estrangulaci\u00f3n severos, como la derivaci\u00f3n alrededor de v\u00e1lvulas de control.Las v\u00e1lvulas de globo en T tambi\u00e9n pueden utilizarse cuando se requiere estrangulaci\u00f3n sin tener en cuenta la ca\u00edda de presi\u00f3n.<\/p>\n\n\n

V\u00e1lvula de globo tipo Y<\/h3>\n\n\n\n
El v\u00e1stago de la v\u00e1lvula de globo tipo Y forma un \u00e1ngulo con el asiento de la v\u00e1lvula, de unos 45 grados. Con una trayectoria de flujo m\u00e1s recta a plena apertura y una resistencia m\u00ednima al flujo, es la menos resistente de las v\u00e1lvulas de globo al flujo. Las superficies de sellado del asiento y la clapeta pueden soldarse con carburo y pueden dejarse abiertas durante largos periodos sin que se produzca una erosi\u00f3n grave. Cuando se utilizan en desag\u00fces que normalmente est\u00e1n cerrados, se pueden hacer pasar por una varilla para eliminar los residuos.<\/p>\n\n\n

V\u00e1lvula de globo de \u00e1ngulo<\/h3>\n\n\n\n
El dise\u00f1o de la v\u00e1lvula de globo en \u00e1ngulo es una modificaci\u00f3n de la v\u00e1lvula de cierre b\u00e1sica de 3 v\u00edas. Estas v\u00e1lvulas de globo tienen \u00e1ngulos de 90 grados en ambos extremos y el flujo de fluido s\u00f3lo da una vuelta de 90 grados, lo que permite instalarlas en \u00e1ngulo recto con el sistema de tuber\u00edas, ahorrando la necesidad de codos de 90\u00b0. Se utilizan en aplicaciones con el flujo pulsante, ya que tienen la capacidad de manejar el efecto de lodos de este tipo de flujo. Este tipo de v\u00e1lvula es el m\u00e1s adecuado para sistemas de producci\u00f3n de amon\u00edaco y para sistemas de refrigeraci\u00f3n en plantas de fertilizantes.<\/p>\n\n\n

Construcci\u00f3n de v\u00e1lvulas de globo<\/h2>\n\n\n\n
Las v\u00e1lvulas de globo est\u00e1n formadas por un cuerpo de v\u00e1lvula, un disco de v\u00e1lvula, un bonete de v\u00e1lvula y un v\u00e1stago de v\u00e1lvula. La parte de apertura y cierre de la v\u00e1lvula de globo es un disco de v\u00e1lvula en forma de obturador con una superficie de sellado plana o c\u00f3nica, que se mueve linealmente a lo largo de la l\u00ednea central del fluido. El v\u00e1stago se acciona de tipo elevador (el v\u00e1stago gira hacia arriba y hacia abajo mediante el volante, que permanece en su posici\u00f3n) y de tipo elevador giratorio (el volante y el v\u00e1stago giran y se mueven juntos hacia arriba y hacia abajo, la contratuerca se encuentra en el cuerpo de la v\u00e1lvula).<\/p>\n\n\n\n
\u00bfC\u00f3mo funcionan las v\u00e1lvulas de globo?<\/h2>\n\n\n\n
La v\u00e1lvula de globo es una v\u00e1lvula de cierre forzado en la que debe aplicarse presi\u00f3n al disco\/obturador para establecer un cierre herm\u00e9tico cuando la v\u00e1lvula est\u00e1 cerrada. Cuando el medio entra en la v\u00e1lvula por debajo de la clapeta, la resistencia que debe vencer la fuerza de accionamiento es la fricci\u00f3n del v\u00e1stago y la empaquetadura y la fuerza generada por la presi\u00f3n del medio. Cuando la fuerza para cerrar la v\u00e1lvula es mayor que la fuerza para abrirla, debe aumentarse el di\u00e1metro del v\u00e1stago para evitar su deformaci\u00f3n y flexi\u00f3n.<\/p>\n\n\n\n
Con la introducci\u00f3n de la v\u00e1lvula de globo con sello de presi\u00f3n, la direcci\u00f3n del flujo del medio en la v\u00e1lvula de globo se cambia desde encima de la aleta de la v\u00e1lvula hacia la cavidad de la v\u00e1lvula. En este caso, la presi\u00f3n del medio reducir\u00e1 la fuerza de cierre de la v\u00e1lvula y aumentar\u00e1 la fuerza de apertura de la v\u00e1lvula, por lo que el di\u00e1metro del v\u00e1stago puede reducirse en consecuencia. Al mismo tiempo, este tipo de v\u00e1lvula es relativamente estanca bajo la acci\u00f3n del medio.<\/p>\n\n\n\n
Funci\u00f3n de las v\u00e1lvulas de globo en el sistema de tuber\u00edas<\/h2>\n\n\n\n
Las v\u00e1lvulas de globo convencionales pueden actuar como aisladores y v\u00e1lvulas de estrangulaci\u00f3n. Aunque las v\u00e1lvulas de globo tienen una ca\u00edda de presi\u00f3n ligeramente superior a las v\u00e1lvulas de paso recto (como las v\u00e1lvulas de compuerta, de macho y de bola), pueden utilizarse cuando la ca\u00edda de presi\u00f3n a trav\u00e9s de la v\u00e1lvula no es un factor de control.<\/p>\n\n\n\n
Las v\u00e1lvulas de globo se utilizan ampliamente para controlar el caudal. El rango de control del caudal y la ca\u00edda de presi\u00f3n deben tenerse en cuenta al dise\u00f1ar la v\u00e1lvula para evitar fallos y garantizar un servicio satisfactorio. Las v\u00e1lvulas para servicios de estrangulaci\u00f3n de alta presi\u00f3n diferencial requieren carretes especialmente dise\u00f1ados.<\/p>\n\n\n\n
En general, la presi\u00f3n diferencial m\u00e1xima a trav\u00e9s de la clapeta de la v\u00e1lvula no debe exceder 20% de la presi\u00f3n m\u00e1xima aguas arriba o 200 psi (1380 kPa), la que sea menor. Para aplicaciones que superen estos l\u00edmites de presi\u00f3n diferencial, las v\u00e1lvulas pueden dise\u00f1arse con embellecedores especiales.<\/p>\n\n\n\n

Flow direction of Globe Valves<\/h2>\r\n\r\n\r\n\r\n\r\nFor applications with low temperatures, Globe valves are normally installed so that the pressure is under the disc. This contributes to an easy operation and helps protect the packing.\r\n\r\n\r\n\r\n\r\n\r\nFor applications with high-temperature steam service, Globe valves are installed so that the pressure is above the disk.

The disk of a Globe valve can be totally removed from the flow path or it can completely close the flow path.\r\n\r\n\r\n\r\n\r\n\r\nGET ADVANTAGES AND DISADVANTAGES OF GLOBE VALVES INFORMATION <\/strong><\/a>\r\n\r\n\r\n\r\n\r\n
Advantages and disadvantages of Globe valves<\/h2>\r\n\r\n\r\n\r\n
ADVANTAGES<\/h3>\r\n\r\n\r\n\r\n
- \r\n \t
- Good shutoff capability<\/li>\r\n \t
- Moderate to good throttling capability<\/li>\r\n \t
- Shorter stroke (compared to a gate valve)<\/li>\r\n \t
- Available in tee, wye, and angle patterns, each offering unique capabilities<\/li>\r\n \t
- Easy to machine or resurface the seats<\/li>\r\n \t
- With the disc not attached to the stem, the valve can be used as a stop-check valve<\/li>\r\n<\/ul>\r\n\r\n\r\n\r\n
DISADVANTAGES<\/h3>\r\n\r\n\r\n\r\n
- \r\n \t
- Higher pressure drop (compared to a gate valve)<\/li>\r\n \t
- Requires greater force or a larger actuator to seat the valve (with pressure under the seat)<\/li>\r\n \t
- Throttling flow under the seat and shutoff flow over the seat<\/li>\r\n<\/ul>\r\n\r\n\r\n\r\n
Flow direction of Globe Valves<\/h2>\r\n\r\n\r\n\r\n\r\nFor applications with low temperatures, Globe valves are normally installed so that the pressure is under the disc. This contributes to an easy operation and helps protect the packing.\r\n\r\n\r\n\r\n\r\n\r\nFor applications with high-temperature steam service, Globe valves are installed so that the pressure is above the disk. Otherwise, the stem will contract upon cooling and tend to lift the disk off the seat.\r\n\r\n\r\n\r\n\r\n
Typical Applications of Globe valves<\/h2>\r\n\r\n\r\n\r\n\r\nThe following are some of the typical applications of Globe valves..\r\n\r\n\r\n\r\n\r\n
- \r\n \t
- Cooling water systems where flow needs to be regulated<\/li>\r\n \t
- Fuel oil system where flow is regulated and leak tightness is of importance<\/li>\r\n \t
- High-point vents and low-point drains when leak tightness and safety are major considerations<\/li>\r\n \t
- Feedwater, chemical feed, condenser air extraction, and extraction drain systems<\/li>\r\n \t
- Boiler vents and drains, main steam vents and drains, and heater drains<\/li>\r\n \t
- Turbine seals and drains<\/li>\r\n \t
- Turbine lube oil system and others<\/li>\r\n<\/ul>\r\n","parent":0,"count":6,"filter":"raw"},{"term_id":1811,"name":"advantages of globe valve","slug":"advantages-of-globe-valve","term_group":0,"term_taxonomy_id":1811,"taxonomy":"post_tag","description":"","parent":0,"count":5,"filter":"raw"},{"term_id":1896,"name":"Disadvantages\u00a0of Globe valve","slug":"disadvantages-of-globe-valve-2","term_group":0,"term_taxonomy_id":1896,"taxonomy":"post_tag","description":"","parent":0,"count":2,"filter":"raw"},{"term_id":1805,"name":"globe valve","slug":"globe-valve","term_group":0,"term_taxonomy_id":1805,"taxonomy":"post_tag","description":"","parent":0,"count":21,"filter":"raw"},{"term_id":1898,"name":"globe valve function","slug":"globe-valve-function","term_group":0,"term_taxonomy_id":1898,"taxonomy":"post_tag","description":"","parent":0,"count":2,"filter":"raw"},{"term_id":1806,"name":"globe valves","slug":"globe-valves","term_group":0,"term_taxonomy_id":1806,"taxonomy":"post_tag","description":"","parent":0,"count":7,"filter":"raw"},{"term_id":1897,"name":"what is the purpose of globe valve in a pipeline","slug":"what-is-the-purpose-of-globe-valve-in-a-pipeline","term_group":0,"term_taxonomy_id":1897,"taxonomy":"post_tag","description":"","parent":0,"count":1,"filter":"raw"}],"taxonomy_info":{"category":[{"value":1,"label":"Uncategorized"}],"post_tag":[{"value":1894,"label":"Advantages and Disadvantages of Globe Valves"},{"value":1811,"label":"advantages of globe valve"},{"value":1896,"label":"Disadvantages\u00a0of Globe valve"},{"value":1805,"label":"globe valve"},{"value":1898,"label":"globe valve function"},{"value":1806,"label":"globe valves"},{"value":1897,"label":"what is the purpose of globe valve in a pipeline"}]},"yoast_head":"\n
