Qu'est-ce qu'un robinet-vanne ?<\/h2>\r\n\r\n\r\n\r\n\r\nUn robinet-vanne, \u00e9galement connu sous le nom de vanne \u00e0 \u00e9cluse, est une vanne qui s'ouvre en soulevant une barri\u00e8re (porte) hors du trajet du fluide. Les vannes \u00e0 vanne n\u00e9cessitent tr\u00e8s peu d'espace le long de l'axe du tuyau et limitent \u00e0 peine le d\u00e9bit de fluide lorsque la vanne est compl\u00e8tement ouverte. Les faces du portail peuvent \u00eatre parall\u00e8les mais sont le plus souvent en forme de coin (afin de pouvoir exercer une pression sur la surface d'\u00e9tanch\u00e9it\u00e9).\r\n\r\n\r\n\r\n\r\n

Comment fonctionne un robinet-vanne ?<\/h2>\r\n\r\n\r\n\r\n\r\nA gate valve is a control valve that either allows media to flow through unobstructed or stops the fluid flow. The main advantage of a gate valve is the straight-through unobstructed passageway, which induces minimal pressure loss over the valve. The unobstructed bore of a gate valve also allows for a pig's passage in cleaning pipe procedures, unlike butterfly valves. However, gate valves are slower than quarter-turn valves and should only be used in the fully open or closed position, not to regulate the flow. Automated gate valves exist with either an electric or pneumatic actuator, but a manual gate valve is cost-effective since gate valves are typically used infrequently. Gate valves are also commonly referred to as sluice gate valves.\r\n\r\n\r\n\r\n\r\n

O\u00f9 sont utilis\u00e9s les robinets-vannes ?<\/h2>\r\n\r\n\r\n\r\n\r\nLes robinets-vannes sont souvent utilis\u00e9s lorsqu'une perte de pression minimale et un al\u00e9sage libre sont n\u00e9cessaires. Lorsqu'il est compl\u00e8tement ouvert, un robinet-vanne typique n'a aucune obstruction dans le chemin d'\u00e9coulement, ce qui entra\u00eene une tr\u00e8s faible perte de pression, et cette conception permet d'utiliser un racleur de nettoyage de tuyaux. Un robinet-vanne est une vanne multitours ce qui signifie que le fonctionnement de la vanne se fait au moyen d'une tige filet\u00e9e. Comme la vanne doit tourner plusieurs fois pour passer de la position ouverte \u00e0 la position ferm\u00e9e, le fonctionnement lent \u00e9vite \u00e9galement les effets de coup de b\u00e9lier.\r\n\r\n\r\n\r\n\r\n

    • Les vannes \u00e0 vanne ne sont pas bien adapt\u00e9es \u00e0 l'\u00e9tranglement (n'importe quelle position de vanne entre compl\u00e8tement ouverte et compl\u00e8tement ferm\u00e9e) car cela cr\u00e9e un \u00e9coulement turbulent et des pertes par frottement. Une vanne laiss\u00e9e en position presque ferm\u00e9e fera circuler le fluide \u00e0 une vitesse tr\u00e8s \u00e9lev\u00e9e \u00e0 travers les surfaces d'appui de la vanne, ce qui peut entra\u00eener des dommages aux surfaces (\u00ab tr\u00e9filage \u00bb) et un passage\/fuite de la vanne.<\/li>\r\n \t
    • Les vannes \u00e0 vanne cr\u00e9ent un \u00e9coulement turbulent lorsqu'elles sont \u00e9trangl\u00e9es et subissent ainsi des vibrations excessives. Cette situation doit \u00eatre \u00e9vit\u00e9e pour \u00e9viter tout dommage \u00e0 la garniture de la vanne et \u00e0 d'autres pi\u00e8ces internes.<\/li>\r\n \t
    • Par rapport \u00e0 un robinet \u00e0 soupape, les surfaces d'appui d'un robinet-vanne sont plus difficiles \u00e0 remettre \u00e0 neuf (si les anneaux de si\u00e8ge ne sont pas utilis\u00e9s)<\/li>\r\n<\/ul>\r\n","link":"https:\/\/zecovalve.com\/fr\/tag\/gate-valve-wiki","name":"Wiki sur les vannes \u00e0 guillotine","slug":"gate-valve-wiki","taxonomy":"post_tag","meta":[],"yoast_head":"\nGate Valve Wikipedia - Gate Valve Manufacturer | 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\/fr\/tag\/gate-valve-wiki\" \/>\n<meta property=\"og:locale\" content=\"fr_FR\" \/>\n<meta property=\"og:type\" content=\"article\" \/>\n<meta property=\"og:title\" content=\"Gate Valve Wikipedia - Gate Valve Manufacturer | ZECO Valve\" \/>\n<meta property=\"og:description\" content=\"GET GATE VALVE WIKI INFORMATION What is a Gate Valve? A gate valve, also known as a sluice valve, is a valve that opens by lifting a barrier (gate) out of the path of the fluid. Gate valves require very little space along the pipe axis and hardly restrict the flow of fluid when the gate is fully opened. The gate faces can be parallel but are most commonly wedge-shaped (in order to be able to apply pressure on the sealing surface). How does a Gate Valve work? A gate valve is a control valve that either allows media to flow through unobstructed or stops the fluid flow. The main advantage of a gate valve is the straight-through unobstructed passageway, which induces minimal pressure loss over the valve. The unobstructed bore of a gate valve also allows for a pig’s passage in cleaning pipe procedures, unlike butterfly valves. However, gate valves are slower than quarter-turn valves and should only be used in the fully open or closed position, not to regulate the flow. Automated gate valves exist with either an electric or pneumatic actuator, but a manual gate valve is cost-effective since gate valves are typically used infrequently. Gate valves are also commonly referred to as sluice gate valves. Where are Gate Valves Used? Gate valves are often used when minimum pressure loss and a free bore are needed. When fully open, a typical gate valve has no obstruction in the flow path resulting in a very low-pressure loss, and this design makes it possible to use a pipe-cleaning pig. A gate valve is a multiturn valve meaning that the operation of the valve is done by means of a threaded stem. As the valve has to turn multiple times to go from the open to the closed position, the slow operation also prevents water hammer effects. Advantages of Gate Valves The gate valve is very simple in design, relatively cheap, and easy to maintain. There is almost no pressure drop across the valve when the valve is in the fully open position. Replacement of the gate valve disc is usually not a difficult task. Replacement of the seat rings is usually not a difficult task. Disadvantages of Gate Valves Gate valves are not well suited to throttling (any valve position between fully open and fully closed) as this creates turbulent flow and frictional losses. A valve left in the almost closed position will cause the flowing medium to flow at a very high velocity across the valve\u2019s seating surfaces, this can lead to damage to the surfaces (\u2018wire-drawing) and passing\/leaking of the valve. Gate valves create turbulent flow when throttled and experience excessive vibration as a result. This situation should be avoided to prevent damage from occurring to the valve packing and other internal parts. Compared to a globe valve, a gate valve\u2019s seating surfaces are more difficult to refurbish (if seat rings are not used)\" \/>\n<meta property=\"og:url\" content=\"https:\/\/zecovalve.com\/fr\/tag\/gate-valve-wiki\" \/>\n<meta property=\"og:site_name\" content=\"ZECO Valve\" \/>\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\/gate-valve-wiki#webpage\",\"url\":\"https:\/\/zecovalve.com\/tag\/gate-valve-wiki\",\"name\":\"Gate Valve Wikipedia - Gate Valve Manufacturer | ZECO Valve\",\"isPartOf\":{\"@id\":\"https:\/\/zecovalve.com\/#website\"},\"breadcrumb\":{\"@id\":\"https:\/\/zecovalve.com\/tag\/gate-valve-wiki#breadcrumb\"},\"inLanguage\":\"fr-FR\",\"potentialAction\":[{\"@type\":\"ReadAction\",\"target\":[\"https:\/\/zecovalve.com\/tag\/gate-valve-wiki\"]}]},{\"@type\":\"BreadcrumbList\",\"@id\":\"https:\/\/zecovalve.com\/tag\/gate-valve-wiki#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\/gate-valve-wiki\",\"url\":\"https:\/\/zecovalve.com\/tag\/gate-valve-wiki\",\"name\":\"Gate Valve Wiki\"}}]}]}<\/script>\n<!-- \/ Yoast SEO Premium plugin. -->","_links":{"self":[{"href":"https:\/\/zecovalve.com\/fr\/wp-json\/wp\/v2\/tags\/1885","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=1885"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
