Qu'est-ce que la vanne de r\u00e9gulation guid\u00e9e par cage\u00a0?<\/h2>\r\n\r\n\r\n\r\n\r\nUne version plus moderne de la conception du robinet \u00e0 soupape utilise un bouchon en forme de piston \u00e0 l'int\u00e9rieur d'une cage environnante avec des orifices moul\u00e9s ou usin\u00e9s \u00e0 l'int\u00e9rieur.\r\n\r\n\r\n\r\n\r\n\r\nCes vannes \u00e0 soupape guid\u00e9es par cage \u00e9tranglent le d\u00e9bit en d\u00e9couvrant plus ou moins la zone du port dans la cage environnante lorsque le clapet monte et descend.

Compared to the stem-guided series, cage guided control valves feature larger trim sizes (available in 2\" to 10\" end connections) for higher valve coefficients (Cv). Cage guided control valves can be equipped with an optional electric drive or operated with compressed air to meet zero-emission requirements.\r\n\r\n\r\n\r\n\r\n

Un bouchon \u00e9quilibr\u00e9 comporte un ou plusieurs ports perc\u00e9s de haut en bas, permettant \u00e0 la pression du fluide de s'\u00e9galiser des deux c\u00f4t\u00e9s du bouchon. Cela permet de minimiser les forces agissant sur le bouchon qui doivent \u00eatre surmont\u00e9es par l'actionneur\u00a0:\r\n\r\n\r\n\r\n\r\n
\"\"<\/figure>\r\n\r\n\r\n\r\n\r\nLes bouchons d\u00e9s\u00e9quilibr\u00e9s g\u00e9n\u00e8rent une force \u00e9gale au produit de la pression diff\u00e9rentielle \u00e0 travers le bouchon et de la surface du bouchon (F = PA), qui peut \u00eatre assez importante dans certaines applications.\r\n\r\n\r\n\r\n\r\n\r\nLes clapets \u00e9quilibr\u00e9s ne g\u00e9n\u00e8rent pas cette m\u00eame force car ils \u00e9galisent la pression des deux c\u00f4t\u00e9s du clapet, cependant, ils pr\u00e9sentent l'inconv\u00e9nient d'un chemin de fuite suppl\u00e9mentaire lorsque la vanne est en position compl\u00e8tement ferm\u00e9e (\u00e0 travers les orifices d'\u00e9quilibrage, au-del\u00e0 du segment de piston). , et hors des ports de la cage)\u00a0:\r\n\r\n\r\n\r\n\r\n
\"\"<\/figure>\r\n\r\n\r\n\r\n\r\nAinsi, les robinets \u00e0 soupape guid\u00e9s par cage, \u00e9quilibr\u00e9s et d\u00e9s\u00e9quilibr\u00e9s, pr\u00e9sentent des caract\u00e9ristiques similaires aux robinets \u00e0 soupape \u00e0 double orifice et \u00e0 un orifice, guid\u00e9s par tige ou par orifice, et pour des raisons similaires.\r\n\r\n\r\n\r\n\r\n\r\nLes vannes \u00e0 cage \u00e9quilibr\u00e9e sont faciles \u00e0 positionner, tout comme les vannes \u00e0 si\u00e8ge \u00e0 double orifice \u00e0 guidage par tige et \u00e0 orifice.\r\n\r\n\r\n\r\n\r\n\r\nCependant, les vannes \u00e9quilibr\u00e9es guid\u00e9es par cage ont tendance \u00e0 fuir davantage lorsqu'elles sont en position ferm\u00e9e en raison d'un plus grand nombre de chemins de fuite, de la m\u00eame mani\u00e8re que les vannes \u00e0 soupape \u00e0 double orifice guid\u00e9es par tige et guid\u00e9es par orifice.\r\n\r\n\r\n\r\n\r\n

A more modern version of the globe valve design uses a piston-shaped plug inside a surrounding cage with ports cast or machined into it. These cage-guided globe valves throttle flow by uncovering more or less of the port area in the surrounding cage as the plug moves up and down. The cage also serves to guide the plug so the stem need not be subjected to lateral forces as in a stem-guided valve design. The Cage guided control valve is a balanced valve that can be used as a dump valve, pressure regulator, suction controller, recirculation valve, and plunger lift applications. Compared to the stem-guided series, cage guided control valves feature larger trim sizes (available in 2″ to 10″ end connections) for higher valve coefficients (Cv). Cage guided control valves can be equipped with an optional electric drive or operated with compressed air to meet zero-emission requirements. Structure of Cage Guided Globe Valve Cage-guided globe valves are available with both balanced and unbalanced plugs. A balanced plug has one or more ports drilled from top to bottom, allowing fluid pressure to equalize on both sides of the plug. This helps minimize the forces acting on the plug which must be overcome by the actuator: Unbalanced plugs generate a force equal to the product of the differential pressure across the plug and the plug\u2019s area (F = PA), which may be quite substantial in some applications. Balanced plugs do not generate this same force because they equalize the pressure on both sides of the plug, however, they exhibit the disadvantage of one more leak path when the valve is in the fully closed position (through the balancing ports, past the piston ring, and out the cage ports): Thus, balanced and unbalanced cage-guided globe valves exhibit similar characteristics to double ported and single-ported stem- or port-guided globe valves, and for similar reasons. Balanced cage guided valves are easy to position, just like double-ported stem-guided and port-guided globe valves. However, balanced cage-guided valves tend to leak more when in the shut position due to a greater number of leak paths, much the same as with double-ported stem-guided and port-guided globe valves. Components of Cage Guide Globe Valve Valve Trims According to the needs of the working conditions, different materials and surface hardening treatments can easily be chosen to meet the requirements of each function module of trim to improve its performance of the corrosion, cavitation, and erosion resistance, and lengthen service life. Valve body The body of LN8 series control valves consists of two passages from upper and lower, forming a shape like a letter “S”. The design of an elliptical section reduces the flow resistance and turbulent flow to keep the flow fluent. The flap in the middle of the upper passage can reduce the eddy flow and increase the flow capacity. Actuator The standard mate is a Multi-spring pneumatic diaphragm actuator, which can be used in many conditions with the features of strong output force, high reliability, long lifespan, and extensive application. The output force changes with the number of springs. The high-stress-resistant diaphragm, bearing maximum pressure of 0.5 MPa air supply, gives the control valve a reliable shutoff. This type of actuator has a long life cycle of more than 1 million times. Features of Cage Guided Control Valve Modular design concept, combining the American and Japanese schools of high-precision control and the German school of the modular concept. The cage valve inner cavity of the valve body is S-shaped distribution, smooth and without dead ends; there are guide wings inside the valve body, which can reduce the mutual force of the medium inside the valve body and reduce the occurrence of cavitation. The use of sleeve guidance, large guide diameter, smooth guidance, with good dynamic stability. The cage valve seat adopts a floating design, while the sealing surface adopts a tapered form to ensure good alignment of the sealing sub. Sleeve window control flow characteristics, flow characteristics control accurately. The structure of the inner part is balanced, allowing a large differential pressure, small operating force, and large flow capacity. Equipment, linear and quick-open flow characteristics are available. Good use in the temperature range of -80 to 593\u2103. And pipeline connection with RF, RJ, FM, and other flange types and SW, and BW welding types. The flange distance conforms to GB\/T 17213.3-2005 \/ IEC 60534-3-1:2000; or ISA S75.03-1992 standard.\" \/>\n<meta property=\"og:url\" content=\"https:\/\/zecovalve.com\/fr\/tag\/cage-guided-control-valve\" \/>\n<meta property=\"og:site_name\" content=\"ZECO Valve\" \/>\n<meta property=\"og:image\" content=\"https:\/\/zecovalve.com\/wp-content\/uploads\/2022\/08\/Control-Valve-0-1024x768.jpg\" \/>\n<meta name=\"twitter:card\" content=\"summary_large_image\" \/>\n<script type=\"application\/ld+json\" class=\"yoast-schema-graph\">{\"@context\":\"https:\/\/schema.org\",\"@graph\":[{\"@type\":\"WebSite\",\"@id\":\"https:\/\/zecovalve.com\/#website\",\"url\":\"https:\/\/zecovalve.com\/\",\"name\":\"ZECO Valve\",\"description\":\"Industrial Ball Valve, Gate Valve and Globe Valve Manufacturer\",\"potentialAction\":[{\"@type\":\"SearchAction\",\"target\":\"https:\/\/zecovalve.com\/?s={search_term_string}\",\"query-input\":\"required name=search_term_string\"}],\"inLanguage\":\"fr-FR\"},{\"@type\":\"CollectionPage\",\"@id\":\"https:\/\/zecovalve.com\/tag\/cage-guided-control-valve#webpage\",\"url\":\"https:\/\/zecovalve.com\/tag\/cage-guided-control-valve\",\"name\":\"Cage Guided Control Valve - Cage Guide Globe Valve | ZECO Valve\",\"isPartOf\":{\"@id\":\"https:\/\/zecovalve.com\/#website\"},\"breadcrumb\":{\"@id\":\"https:\/\/zecovalve.com\/tag\/cage-guided-control-valve#breadcrumb\"},\"inLanguage\":\"fr-FR\",\"potentialAction\":[{\"@type\":\"ReadAction\",\"target\":[\"https:\/\/zecovalve.com\/tag\/cage-guided-control-valve\"]}]},{\"@type\":\"BreadcrumbList\",\"@id\":\"https:\/\/zecovalve.com\/tag\/cage-guided-control-valve#breadcrumb\",\"itemListElement\":[{\"@type\":\"ListItem\",\"position\":1,\"item\":{\"@type\":\"WebPage\",\"@id\":\"https:\/\/zecovalve.com\/\",\"url\":\"https:\/\/zecovalve.com\/\",\"name\":\"Home\"}},{\"@type\":\"ListItem\",\"position\":2,\"item\":{\"@type\":\"WebPage\",\"@id\":\"https:\/\/zecovalve.com\/tag\/cage-guided-control-valve\",\"url\":\"https:\/\/zecovalve.com\/tag\/cage-guided-control-valve\",\"name\":\"Cage Guided Control Valve\"}}]}]}<\/script>\n<!-- \/ Yoast SEO Premium plugin. -->","_links":{"self":[{"href":"https:\/\/zecovalve.com\/fr\/wp-json\/wp\/v2\/tags\/3226","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/zecovalve.com\/fr\/wp-json\/wp\/v2\/tags"}],"about":[{"href":"https:\/\/zecovalve.com\/fr\/wp-json\/wp\/v2\/taxonomies\/post_tag"}],"wp:post_type":[{"href":"https:\/\/zecovalve.com\/fr\/wp-json\/wp\/v2\/posts?tags=3226"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
