Was ist ein Absperrschieber?<\/h2>\r\n\r\n\r\n\r\n\r\nEin Schieber, auch Schleusenventil genannt, ist ein Ventil, das sich \u00f6ffnet, indem es eine Barriere (ein Tor) aus dem Weg der Fl\u00fcssigkeit hebt. Schieber ben\u00f6tigen sehr wenig Platz entlang der Rohrachse und schr\u00e4nken den Fl\u00fcssigkeitsfluss kaum ein, wenn das Tor vollst\u00e4ndig ge\u00f6ffnet ist. Die Torfl\u00e4chen k\u00f6nnen parallel sein, sind aber meistens keilf\u00f6rmig (um Druck auf die Dichtfl\u00e4che aus\u00fcben zu k\u00f6nnen).\r\n\r\n\r\n\r\n\r\n

Wie funktioniert ein Absperrventil?<\/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

Wo werden Absperrschieber eingesetzt?<\/h2>\r\n\r\n\r\n\r\n\r\nSchieberventile werden h\u00e4ufig verwendet, wenn minimaler Druckverlust und ein freier Durchgang erforderlich sind. Bei vollst\u00e4ndiger \u00d6ffnung weist ein typisches Schieberventil keine Behinderung im Str\u00f6mungsweg auf, was zu einem sehr geringen Druckverlust f\u00fchrt. Diese Konstruktion erm\u00f6glicht au\u00dferdem die Verwendung eines Rohrreinigungsmolches. Ein Schieberventil ist ein Mehrdrehventil, was bedeutet, dass die Bet\u00e4tigung des Ventils \u00fcber eine Gewindespindel erfolgt. Da sich das Ventil mehrere Male drehen muss, um von der offenen in die geschlossene Position zu gelangen, verhindert die langsame Bet\u00e4tigung auch Wasserschlageffekte.\r\n\r\n\r\n\r\n\r\n

Vorteile von Schieberventilen<\/h2>\r\n\r\n\r\n\r\n
    \r\n \t
  • Das Absperrventil ist sehr einfach aufgebaut, relativ g\u00fcnstig und leicht zu warten.<\/li>\r\n \t
  • Wenn das Ventil vollst\u00e4ndig ge\u00f6ffnet ist, tritt am Ventil nahezu kein Druckabfall auf.<\/li>\r\n \t
  • Der Austausch der Schieberscheibe ist normalerweise keine schwierige Aufgabe.<\/li>\r\n \t
  • Der Austausch der Sitzringe ist normalerweise keine schwierige Aufgabe.<\/li>\r\n<\/ul>\r\n\r\n\r\n\r\n

    Nachteile von Absperrschiebern<\/h2>\r\n\r\n\r\n\r\n
      \r\n \t
    • Schieber sind nicht gut zum Drosseln geeignet (jede Ventilposition zwischen vollst\u00e4ndig ge\u00f6ffnet und vollst\u00e4ndig geschlossen), da dies zu turbulenten Str\u00f6mungen und Reibungsverlusten f\u00fchrt. Ein Ventil in nahezu geschlossener Position f\u00fchrt dazu, dass das flie\u00dfende Medium mit sehr hoher Geschwindigkeit \u00fcber die Ventilsitzfl\u00e4chen flie\u00dft. Dies kann zu Sch\u00e4den an den Oberfl\u00e4chen (\u201eDrahtziehen\u201c) und zum Durchsickern\/Lecken des Ventils f\u00fchren.<\/li>\r\n \t
    • Schieberventile erzeugen bei Drosselung einen turbulenten Durchfluss und erleiden dadurch \u00fcberm\u00e4\u00dfige Vibrationen. Diese Situation sollte vermieden werden, um Sch\u00e4den an der Ventilpackung und anderen Innenteilen zu vermeiden.<\/li>\r\n \t
    • Im Vergleich zu einem Absperrventil sind die Sitzfl\u00e4chen eines Schieberventils schwieriger zu erneuern (wenn keine Sitzringe verwendet werden).<\/li>\r\n<\/ul>\r\n","link":"https:\/\/zecovalve.com\/de\/tag\/gate-valve-wiki","name":"Absperrschieber Wiki","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\/de\/tag\/gate-valve-wiki\" \/>\n<meta property=\"og:locale\" content=\"de_DE\" \/>\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\/de\/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\":\"de\"},{\"@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\":\"de\",\"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\/de\/wp-json\/wp\/v2\/tags\/1885","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/zecovalve.com\/de\/wp-json\/wp\/v2\/tags"}],"about":[{"href":"https:\/\/zecovalve.com\/de\/wp-json\/wp\/v2\/taxonomies\/post_tag"}],"wp:post_type":[{"href":"https:\/\/zecovalve.com\/de\/wp-json\/wp\/v2\/posts?tags=1885"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
