Mod\u00e8le en T\/vanne \u00e0 soupape droite<\/h3>\n\n\n\n
La conception de vanne en T est le type de corps de vanne le plus courant, qui pr\u00e9sente un chemin d'\u00e9coulement d'entr\u00e9e et de sortie de 180\u00b0 dans la m\u00eame direction et un r\u00e9glage horizontal du si\u00e8ge de vanne permettant \u00e0 la tige et au disque de se d\u00e9placer perpendiculairement \u00e0 la ligne horizontale. Cette conception a un faible coefficient de d\u00e9bit et une faible perte de charge. Ils sont utilis\u00e9s dans des services d'\u00e9tranglement s\u00e9v\u00e8res tels que le contournement autour des vannes de r\u00e9gulation. Les vannes \u00e0 soupape en T peuvent \u00e9galement \u00eatre utilis\u00e9es lorsqu'un \u00e9tranglement est requis sans tenir compte de la chute de pression.<\/p>\n\n\n

La tige du robinet \u00e0 soupape de type Y forme un angle avec le si\u00e8ge de soupape, d'environ 45 degr\u00e9s. Avec un chemin d'\u00e9coulement plus droit \u00e0 pleine ouverture et une r\u00e9sistance minimale \u00e0 l'\u00e9coulement, c'est le robinet \u00e0 soupape le moins r\u00e9sistant \u00e0 l'\u00e9coulement. Les surfaces d'\u00e9tanch\u00e9it\u00e9 du si\u00e8ge et du rabat peuvent \u00eatre soud\u00e9es avec du carbure et peuvent rester ouvertes pendant de longues p\u00e9riodes sans \u00e9rosion importante. Lorsqu'ils sont utilis\u00e9s dans des drains normalement ferm\u00e9s, ils peuvent \u00eatre pass\u00e9s \u00e0 travers une tige pour \u00e9liminer les d\u00e9bris.<\/p>\n\n\n

Vanne \u00e0 soupape coud\u00e9e<\/h3>\n\n\n\n
La conception du robinet \u00e0 soupape d'angle est une modification de la vanne d'arr\u00eat \u00e0 3 voies de base. Ces robinets \u00e0 soupape ont des angles de 90 degr\u00e9s aux deux extr\u00e9mit\u00e9s et le d\u00e9bit de fluide ne repr\u00e9sente qu'un tour de 90 degr\u00e9s, ce qui leur permet d'\u00eatre install\u00e9s \u00e0 angle droit par rapport au syst\u00e8me de tuyauterie, \u00e9vitant ainsi le besoin de coudes \u00e0 90\u00b0. Ils sont utilis\u00e9s dans les applications \u00e0 flux puls\u00e9 car ils ont la capacit\u00e9 de g\u00e9rer l\u2019effet de boue de ce type de flux. Ce type de vanne est particuli\u00e8rement adapt\u00e9 aux syst\u00e8mes de production d'ammoniac et aux syst\u00e8mes de r\u00e9frig\u00e9ration des usines d'engrais.<\/p>\n\n\n

Construction des robinets \u00e0 soupape<\/h2>\n\n\n\n
Les vannes \u00e0 soupape sont constitu\u00e9es d'un corps de vanne, d'un disque de vanne, d'un chapeau de vanne et d'une tige de vanne. La partie d'ouverture et de fermeture du robinet \u00e0 soupape est un disque de vanne en forme de bouchon avec une surface d'\u00e9tanch\u00e9it\u00e9 plate ou conique, qui se d\u00e9place lin\u00e9airement le long de la ligne centrale du fluide. La tige fonctionne en type \u00e0 levage (la tige est tourn\u00e9e de haut en bas par le volant, qui reste dans sa position) et en type \u00e0 levage rotatif (le volant et la tige tournent et montent et descendent ensemble, le contre-\u00e9crou est situ\u00e9 sur la vanne corps).<\/p>\n\n\n\n
Comment fonctionnent les vannes \u00e0 soupape ?<\/h2>\n\n\n\n
La vanne \u00e0 soupape est une vanne \u00e0 joint forc\u00e9 o\u00f9 une pression doit \u00eatre appliqu\u00e9e sur le disque\/bouchon pour \u00e9tablir un joint \u00e9tanche lorsque la vanne est ferm\u00e9e. Lorsque le fluide p\u00e9n\u00e8tre dans la vanne par le dessous du clapet, la r\u00e9sistance \u00e0 vaincre par la force de fonctionnement est le frottement de la tige et de la garniture ainsi que la force g\u00e9n\u00e9r\u00e9e par la pression du fluide. Lorsque la force n\u00e9cessaire pour fermer la vanne est sup\u00e9rieure \u00e0 la force n\u00e9cessaire pour ouvrir la vanne, le diam\u00e8tre de la tige doit \u00eatre augment\u00e9 pour \u00e9viter toute distorsion et flexion de la tige.<\/p>\n\n\n\n
Avec l'introduction du robinet \u00e0 soupape \u00e0 joint de pression, la direction du flux de fluide dans le robinet \u00e0 soupape est modifi\u00e9e du dessus du clapet de la vanne vers la cavit\u00e9 de la vanne. Dans ce cas, la pression du fluide r\u00e9duira la force de fermeture de la vanne et augmentera la force d'ouverture de la vanne, de sorte que le diam\u00e8tre de la tige puisse \u00eatre r\u00e9duit en cons\u00e9quence. En m\u00eame temps, ce type de vanne est relativement \u00e9tanche sous l'action du fluide.<\/p>\n\n\n\n
La fonction des vannes \u00e0 soupape dans le syst\u00e8me de canalisations<\/h2>\n\n\n\n
Les vannes \u00e0 soupape conventionnelles peuvent servir d'isolateurs et de vannes d'\u00e9tranglement. Bien que les vannes \u00e0 soupape aient une chute de pression l\u00e9g\u00e8rement plus \u00e9lev\u00e9e que les vannes \u00e0 passage direct (telles que les vannes \u00e0 vanne, \u00e0 boisseau et \u00e0 bille), elles peuvent \u00eatre utilis\u00e9es lorsque la chute de pression \u00e0 travers la vanne n'est pas un facteur de contr\u00f4le.<\/p>\n\n\n\n
Les vannes \u00e0 soupape sont largement utilis\u00e9es pour contr\u00f4ler le d\u00e9bit. La plage de contr\u00f4le du d\u00e9bit et la chute de pression doivent \u00eatre prises en compte lors de la conception de la vanne pour \u00e9viter toute d\u00e9faillance et garantir un service satisfaisant. Les vannes destin\u00e9es aux services d'\u00e9tranglement \u00e0 pression diff\u00e9rentielle \u00e9lev\u00e9e n\u00e9cessitent des tiroirs sp\u00e9cialement con\u00e7us.<\/p>\n\n\n\n
En g\u00e9n\u00e9ral, la pression diff\u00e9rentielle maximale \u00e0 travers le clapet de la vanne ne doit pas d\u00e9passer 20% de la pression maximale en amont ou 200 psi (1 380 kPa), selon la valeur la plus basse. Pour les applications d\u00e9passant ces limites de pression diff\u00e9rentielle, les vannes peuvent \u00eatre con\u00e7ues avec des \u00e9l\u00e9ments internes sp\u00e9ciaux.<\/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
