Die Klappe in einem R\u00fcckschlagventil \u201eschwingt\u201c vom Sitz weg, um einen Vorw\u00e4rtsfluss zu erm\u00f6glichen, und schwingt dann zur\u00fcck auf den Sitz, wenn der Fluss gestoppt wird. Im Gegensatz dazu enth\u00e4lt ein R\u00fcckschlagventil mit Federn eine Feder, die beim Schlie\u00dfen des R\u00fcckschlagventils hilft.<\/p>\n\n\n\n<p>R\u00fcckschlagventile sind in ihrer Einbaulage beschr\u00e4nkt. R\u00fcckschlagventile k\u00f6nnen nur in horizontalen Durchflussanwendungen eingebaut werden, was die Einbaulage stark einschr\u00e4nkt. Obwohl R\u00fcckschlagventile eine gr\u00f6\u00dfere Durchflusskapazit\u00e4t bieten (h\u00f6herer CV-Wert, vorausgesetzt, das Ventil ist vollst\u00e4ndig ge\u00f6ffnet), passen sie nicht immer in vorhandene Rohrleitungskonfigurationen. Federbelastete R\u00fcckschlagventile hingegen k\u00f6nnen mit der richtigen Federauswahl in jeder Durchflusslage eingebaut werden. Wenn Sie also ein Gleitsystem, einen schwierigen Raum mit herausfordernden Abmessungen oder sogar eine einzigartige Rohrleitungsrichtung haben, bietet die Wahl eines Federr\u00fcckschlagventils mit der richtigen Federeinstellung (auch Feder\u00f6ffnungsdruck genannt) mehr M\u00f6glichkeiten, die richtige L\u00f6sung f\u00fcr Ihr spezifisches Pumpensystem zu finden.<\/p>\n\n\n\n<p>Ein federbelastetes R\u00fcckschlagventil hilft, die Auswirkungen des Wasserschlags zu minimieren, w\u00e4hrend ein R\u00fcckschlagventil das Problem verschlimmern kann. Alle in einem Rohrleitungssystem vorhandenen Wasserschlageffekte k\u00f6nnen durch ein R\u00fcckschlagventil m\u00f6glicherweise verst\u00e4rkt werden. Betrachten wir dieses einfache Beispiel, um das Konzept eines Wasserschlags zu erkl\u00e4ren: Angenommen, Sie haben eine Leitung mit Wasser darin und ein R\u00fcckschlagventil. Hinter diesem R\u00fcckschlagventil befindet sich ein Kugelhahn mit Vierteldrehung (dies ist einer der am h\u00e4ufigsten verwendeten Arten von Regelventilen f\u00fcr kleinere Leitungsgr\u00f6\u00dfen). Angenommen, Wasser flie\u00dft und jemand schlie\u00dft den Kugelhahn mit Vierteldrehung abrupt. Dies kann eine Druckwelle erzeugen, die durch die Rohrleitung flie\u00dft \u2013 das ist das, was als Wasserschlag bezeichnet wird. Insbesondere bei einem R\u00fcckschlagventil bleibt die Klappe an diesem Ventil ge\u00f6ffnet, bis die Druckwelle zum R\u00fcckschlagventil zur\u00fcckkehrt. Die Druckwelle l\u00e4sst die Klappe zuschlagen, was deutlich h\u00f6rbar ist und zu \u00fcberm\u00e4\u00dfigem Verschlei\u00df des R\u00fcckschlagventils und anderer Komponenten des Rohrleitungssystems f\u00fchrt.<\/p>\n\n\n\n<p>Umgekehrt hilft ein federbelastetes R\u00fcckschlagventil, die Auswirkungen eines Wasserschlags zu minimieren und in manchen F\u00e4llen sogar zu eliminieren. Wie? Wenn wir an dieselbe Druckwelle denken, die das R\u00fcckschlagventil geschlossen hat, schlie\u00dft die Feder im Federr\u00fcckschlagventil, bevor die Druckwelle dort ankommt. Federr\u00fcckschlagventile gelten als \u201eger\u00e4uschlose R\u00fcckschlagventile\u201c, da sie eine Feder verwenden, die den Ventilkegel beim Schlie\u00dfen des R\u00fcckschlagventils unterst\u00fctzt, bevor der Fl\u00fcssigkeitsfluss umgekehrt wird.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Anwendungen von R\u00fcckschlagventilen<\/h2>\n\n\n\n<p>Ventile werden verwendet, um den R\u00fcckfluss von Medien in Rohrleitungen und Ger\u00e4ten zu verhindern. Der Druck des Mediums bewirkt ein automatisches \u00d6ffnen und Schlie\u00dfen.<\/p>\n\n\n\n<p>Bei einem R\u00fcckfluss des Mediums wird die Ventilscheibe automatisch geschlossen, um Unf\u00e4lle zu vermeiden.<\/p>\n\n\n\n<!-- Andy:h-related-tags -->\n<h2 id=\"h-related-tags\">Verwandte Tags:<\/h2>\n<!-- \/Andy:h-related-tags -->\n\n\n\n<div class=\"re_main\">\n<a

Check valves are simple devices that perform a vital function by preventing reverse flows, therefore preventing damage and ensuring efficient operations. Different types of check valves are designed for a specific application. To help you choose the right check valve for your needs, here are a few of the most common types of check valves and their recommended applications.

For a check valve to open, it must attain a minimum upstream pressure known as cracking pressure. Depending on the check valve design and size, the cracking pressure changes. When the upstream pressure reaches the cracking pressure, the valve opens allowing the fluid to enter. When the upstream pressure falls below the cracking pressure, back pressure is generated and the flow attempt to move from outlet to inlet. At this point, the check valve closes, and the flow halts. The closing mechanism of a check valve varies depending on the design and type of the valve. Spring or Gravity pressure normally assist the closing process.\r\n\r\n<!-- \/wp:paragraph -->\r\n\r\n<!-- wp:heading -->\r\n<h2>Check Valve Types<\/h2>\r\n<!-- \/wp:heading -->\r\n\r\n<!-- wp:heading {\"level\":3} -->\r\n<h3>Lift Check Valve<\/h3>\r\n<!-- \/wp:heading -->\r\n\r\n<!-- wp:paragraph -->\r\n\r\nLift-check valves feature a guided disc and a similar seating arrangement as globe valves. The disc is usually in the form of a piston or a ball. There are three body patterns (horizontal, angle, and vertical) that can be installed in horizontal or vertical lines with upward flow.\r\n\r\n<!-- \/wp:paragraph -->\r\n\r\n<!-- wp:paragraph -->\r\n\r\nWhen the flow enters below the seat, a disk is raised from the seat by the pressure of the upward flow. When the flow stops or reverses, the backflow and gravity force the disk downward to set on the seat.\r\n\r\n<!-- \/wp:paragraph -->\r\n\r\n<!-- wp:paragraph -->\r\n\r\nLift check valves are particularly suitable for high-pressure service where the velocity of flow is high. They are commonly used in high-rise buildings, industrial and power plant applications, and water and wastewater applications. They have no external moving parts and are known to be economical and reliable. Over time, these types of check valves can have high energy costs because the disc remains in the flow stream during operation.\r\n\r\n<!-- \/wp:paragraph -->\r\n\r\n<!-- wp:paragraph -->\r\n\r\nThere are two types of lift check valves:\r\n\r\n<!-- \/wp:paragraph -->\r\n\r\n<!-- wp:heading {\"level\":4} -->\r\n<h4>Piston Check Valve<\/h4>\r\n<!-- \/wp:heading -->\r\n\r\n<!-- wp:paragraph -->\r\n\r\nThis type of check valve is also known as a plug check valve. It operates by controlling the flow of fluid in a piping system utilizing the linear motion of a piston within the valve chamber. Sometimes the piston has a spring attached, which helps it stay in the closed position when not in use.\r\n\r\n<!-- \/wp:paragraph -->\r\n\r\n<!-- wp:heading {\"level\":4} -->\r\n<h4>Ball Check Valve<\/h4>\r\n<!-- \/wp:heading -->\r\n\r\n<!-- wp:paragraph -->\r\n\r\nThe ball check valve operates simply using gravity. When there is enough pressure in the flow, the ball is lifted upward, and when the pressure is decreased, the ball rolls down and closes the opening. Ball Check Valves come in a wide range of material types and style types.\r\n\r\n<!-- \/wp:paragraph -->\r\n\r\n<!-- wp:heading {\"level\":3} -->\r\n<h3>Swing Check Valve<\/h3>\r\n<!-- \/wp:heading -->\r\n\r\n<!-- wp:paragraph -->\r\n\r\nSwing Check Valves are available in straight body design and y-pattern design. The disk is suspended from the body by means of a hinge pin and seals against the seat which is integral to the body.\r\n\r\n<!-- \/wp:paragraph -->\r\n\r\n<!-- wp:paragraph -->\r\n\r\nThese valves are typically used in sizes 2 inches and over. Swing check valves can be installed in both horizontal and vertical positions. They are not suitable for pulsating flow.\r\n\r\n<!-- \/wp:paragraph -->\r\n\r\n<!-- wp:paragraph -->\r\n\r\nThe closure response of the swing check valve is slower compared to the lift check valve due to longer disc travel and inertia of the disk.\r\n\r\n<!-- \/wp:paragraph -->\r\n\r\n<!-- wp:heading {\"level\":4} -->\r\n<h4>Specifications of Swing Check Valve<\/h4>\r\n<!-- \/wp:heading -->\r\n\r\n<!-- wp:list -->\r\n<ul>\r\n \t<li>Valve Design: BS 1868 \/ API 6D<\/li>\r\n \t<li>Pressure Testing: BS 6755-I<\/li>\r\n \t<li>Face To Face: ANSI B 16.10<\/li>\r\n \t<li>Flange Drilling : ANSI B 16.5 \/ BS 10 Table \/ DIN \/ IS \/ JIS Std.<\/li>\r\n \t<li>Butt Weld End: ANSI B 16.25<\/li>\r\n \t<li>Face to Face: ANSI B 16.10<\/li>\r\n \t<li>Socket Weld End: ANSI B 16.11<\/li>\r\n \t<li>Screwed End: ANSI B 1.20.1(BSP\/NPT)<\/li>\r\n<\/ul>\r\n<!-- \/wp:list -->\r\n\r\n<!-- wp:heading {\"level\":3} -->\r\n<h3>Tilting Disc Check Valve<\/h3>\r\n<!-- \/wp:heading -->\r\n\r\n<!-- wp:paragraph -->\r\n\r\nThe tilting disc check valve is similar in appearance to an eccentric butterfly valve. The valve body is double\u2010flanged and of a short length. The disc is held in place via a shaft which is positioned eccentrically from the body centreline in both the horizontal and vertical axes.\r\n\r\n<!-- \/wp:paragraph -->\r\n\r\n<!-- wp:paragraph -->\r\n\r\nThe double eccentricity of the shaft results in the lower section of the disc occupying a greater area in the flow path. Consequently, the disc begins to open at very low flow rates. The tilting disc check valve is therefore commonly used in pumping systems with low flow rates and also for pulsating flows.\r\n\r\n<!-- \/wp:paragraph -->\r\n\r\n<!-- wp:paragraph -->\r\n\r\nDuring flow reversal, the disc closes due to gravity and the upper part of the disc above the shaft centreline pushes against the flow thus acting as a hydraulic brake that cushions the disc as it returns to the closed position. Tilting disc valves can be supplied with optional levers and weights to adjust the closing characteristics of the valve. As such, the tilting disc check valves are well suited to reduce the risk of water hammers.\r\n\r\n<!-- \/wp:paragraph -->\r\n\r\n<!-- wp:heading {\"level\":3} -->\r\n<h3>Butterfly Check Valve<\/h3>\r\n<!-- \/wp:heading -->\r\n\r\n<!-- wp:paragraph -->\r\n\r\nA butterfly check valve is known as a dual plate check valve, folding disc check valve, double-disc, or split disc check valve. As the name suggests, two halves of the disk move towards the centerline with the forward flow, and with reverse flow two halves open and rest on the seat to close the flow.\r\n\r\n<!-- \/wp:paragraph -->\r\n\r\n<!-- wp:paragraph -->\r\n\r\nThese types of check valves are good for low-pressure liquid systems as well as gas piping systems. Its lightweight and compact construction make it a preferable choice when space and convenience are important. Besides, it is 80 to 90% lighter than the conventional full-body check valve and the cost of installation and maintenance is lower compared to other types.\r\n\r\n<!-- \/wp:paragraph -->\r\n\r\n<!-- wp:heading {\"level\":3} -->\r\n<h3>Stop Check Valve<\/h3>\r\n<!-- \/wp:heading -->\r\n\r\n<!-- wp:paragraph -->\r\n\r\nStop-check valves can be used for many applications. They\u2019re designed to start, stop, and regulate the flow of materials, and they help to prevent backflow.\r\n\r\n<!-- \/wp:paragraph -->\r\n\r\n<!-- wp:paragraph -->\r\n\r\nIf the pressure in the system is too low, these valves will automatically close to prevent reverse flow. As a result, damage usually caused by backflow is prevented.\r\n\r\n<!-- \/wp:paragraph -->\r\n\r\n<!-- wp:paragraph -->\r\n\r\nstop-check-valveThese types of check valves also work with an external mechanism or an override control. With these, you can set the valve to close regardless of flow direction or pressure to ensure safe and efficient operations.\r\n\r\n<!-- \/wp:paragraph -->\r\n\r\n<!-- wp:paragraph -->\r\n\r\nGenerally, stop-check valves are used in power plants and boiler systems. They\u2019re also beneficial for petroleum production and refining, hydrocarbon processing, and high-pressure safety services.\r\n\r\n<!-- \/wp:paragraph -->\r\n\r\n<!-- wp:heading {\"level\":3} -->\r\n<h3>Diaphragm Check Valve<\/h3>\r\n<!-- \/wp:heading -->\r\n\r\n<!-- wp:paragraph -->\r\n\r\nDiaphragm check valves consist of rubber flexing diaphragms or self-centering discs for preventing backflow. When the inlet pressure is increased, the diaphragm flexes open, and flow starts. There are two types of diaphragm check valves;\r\n\r\n<!-- \/wp:paragraph -->\r\n\r\n<!-- wp:list -->\r\n<ul>\r\n \t<li>Free-floating Normally Open Valve<\/li>\r\n \t<li>Fixed Flexing Normally closed Valve<\/li>\r\n<\/ul>\r\n<!-- \/wp:list -->\r\n\r\n<!-- wp:paragraph -->\r\n\r\nIn the case of normally open diaphragm valves, no cracking pressure is required as the self-centering elastomeric diaphragm is free-floating. However, they need back pressure to close the valve. On the other hand, normally closed valves need a certain inlet pressure to overcome the elasticity of the fixed diaphragm.\r\n\r\n<!-- \/wp:paragraph -->\r\n\r\n<!-- wp:paragraph -->\r\n\r\nDue to very low cracking pressure, Diaphragm check valves find their use in low pressure and vacuum applications.\r\n\r\n<!-- \/wp:paragraph -->\r\n\r\n<!-- wp:heading {\"level\":3} -->\r\n<h3>Spring Loaded Check Valve<\/h3>\r\n<!-- \/wp:heading -->\r\n\r\n<!-- wp:paragraph -->\r\n\r\nThere are two types of Spring Loaded Check Valves; Spring Loaded in-line valves and Spring loaded Y-valves.\r\n\r\n<!-- \/wp:paragraph -->\r\n\r\n<!-- wp:heading {\"level\":4} -->\r\n<h4>Spring Loaded in-line valve<\/h4>\r\n<!-- \/wp:heading -->\r\n\r\n<!-- wp:paragraph -->\r\n\r\nIn-line valves are also known as Nozzle Check Valves or Silent Check Valves. These valves employ a centrally guided stem-disc assembly along with a compression spring. To open the valve, the flow pressure must be more than the spring force and cracking pressure. In that case, the flow pushes the disc allowing the flow. When the inlet pressure reduces, the spring pushes the disc against the orifice and shut the valve.\r\n\r\n<!-- \/wp:paragraph -->\r\n\r\n<!-- wp:heading {\"level\":4} -->\r\n<h4>Spring Loaded Y-valve<\/h4>\r\n<!-- \/wp:heading -->\r\n\r\n<!-- wp:paragraph -->\r\n\r\nThe operating principle of Spring-loaded y-check valves is similar to in-line check valves. The only difference is that the spring and movable disc are located at an angle to form a \u2018y\u2019 shape. The main advantage of Y-type check valves is that they can be inspected and serviced while the valve is still connected to the system.\r\n\r\n<!-- \/wp:paragraph -->\r\n\r\n<!-- wp:heading {\"level\":3} -->\r\n<h3>Foot Check Valve<\/h3>\r\n<!-- \/wp:heading -->\r\n\r\n<!-- wp:paragraph -->\r\n\r\nA foot valve is a check valve that has a strainer installed on the inlet side to prevent debris from entering the valve.\r\n\r\n<!-- \/wp:paragraph -->\r\n\r\n<!-- wp:heading {\"level\":3} -->\r\n<h3>Duckbill Check Valve<\/h3>\r\n<!-- \/wp:heading -->\r\n\r\n<!-- wp:paragraph -->\r\n\r\nDuckbill Check Valves are unique, one-piece, elastomeric components that enable flow to proceed through a soft tube that feeds into the downstream side of the valve wherein back pressure collapses the tube and cuts off the flow.\r\n\r\n<!-- \/wp:paragraph -->\r\n\r\n<!-- wp:heading {\"level\":3} -->\r\n<h3>Wafer Check Valve<\/h3>\r\n<!-- \/wp:heading -->\r\n\r\n<!-- wp:paragraph -->\r\n\r\nWafer check valves are very slim and compact in design and use a swinging disc to allow or block flow. They are lightweight and suitable for various applications. They are economical and are available in various sizes. The following figure shows the typical working of a Wafer Check Valve.\r\n\r\n<!-- \/wp:paragraph -->\r\n\r\n<!-- wp:paragraph -->\r\n\r\nWafer check valves are ideal for services requiring low-pressure loss as the valve operation takes place at a very low-pressure difference.\r\n\r\n<!-- \/wp:paragraph -->\r\n\r\n<!-- wp:heading {\"level\":3} -->\r\n<h3>Silent Check Valve<\/h3>\r\n<!-- \/wp:heading -->\r\n\r\n<!-- wp:paragraph -->\r\n\r\nSilent check valves are incredibly useful for water pipelines and systems. These valves are engineered to control and protect against pressure surges that can occur in water lines. They also work to prevent water hammer and reverse flow.\r\n\r\n<!-- \/wp:paragraph -->\r\n\r\n<!-- wp:paragraph -->\r\n\r\nSilent check valves are constructed with a spring-assisted disc. When the fluid pressure in the valve is higher than the cracking pressure, or the pressure needed open or close the valve, the spring lowers the disc to prevent reverse flow.\r\n\r\n<!-- \/wp:paragraph -->\r\n\r\n<!-- wp:paragraph -->\r\n\r\nThe valve is also manufactured to include a guide to keep the disc moving in vertically. This allows it to reseat properly.\r\n\r\n<!-- \/wp:paragraph -->\r\n\r\n<!-- wp:heading {\"level\":3} -->\r\n<h3>Non-slam Check Valve<\/h3>\r\n<!-- \/wp:heading -->\r\n\r\n<!-- wp:paragraph -->\r\n\r\nThe swing check valve closes abruptly because of gravity and causes a pressure surge resulting in shock waves.\r\n\r\n<!-- \/wp:paragraph -->\r\n\r\n<!-- wp:paragraph -->\r\n\r\nThese high-pressure waves cause severe stress on the piping system.\r\n\r\n<!-- \/wp:paragraph -->\r\n\r\n<!-- wp:paragraph -->\r\n\r\nThis problem can be minimized by installing a Non-Slam type check valve. Non-Slam check valves do not rely on gravity. As the upstream velocity of the fluid slows the spring assist on the valve start to close the disc.\r\n\r\n<!-- \/wp:paragraph -->\r\n\r\n<!-- wp:paragraph -->\r\n\r\nBy the time the upstream velocity comes to 0, the disc is completely closed. With the reverse flow eliminated, the force necessary to produce a water hammer on either side of the valve is substantially reduced.\r\n\r\n<!-- \/wp:paragraph -->","parent":0,"count":13,"filter":"raw"},{"term_id":2821,"name":"Types of Check Valves","slug":"types-of-check-valves","term_group":0,"term_taxonomy_id":2821,"taxonomy":"post_tag","description":"","parent":0,"count":3,"filter":"raw"},{"term_id":3551,"name":"upvc spring check valve factory","slug":"upvc-spring-check-valve-factory","term_group":0,"term_taxonomy_id":3551,"taxonomy":"post_tag","description":"","parent":0,"count":1,"filter":"raw"}],"taxonomy_info":{"category":[{"value":1,"label":"Uncategorized"}],"post_tag":[{"value":2343,"label":"check valve"},{"value":3552,"label":"ptfe seat supplier"},{"value":3553,"label":"Spring Check Valve"},{"value":3554,"label":"Spring Check Valve vs Swing Check Valve"},{"value":2820,"label":"Types of Check Valve"},{"value":2821,"label":"Types of Check Valves"},{"value":3551,"label":"upvc spring check valve factory"}]},"yoast_head":"<!-- This site is optimized with the Yoast SEO Premium plugin v15.4 - https:\/\/yoast.com\/wordpress\/plugins\/seo\/ -->\n<title>UPVC Spring Check Valve Factory - Spring Check Valve vs Swing Check 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\/zeco-valve-latest-company-news-about-bsp-end-y-type-spring-check-valve-800-psi-ss316-full-port-ptfe-seat-quality-valve-supplier.html\" \/>\n<meta property=\"og:locale\" content=\"de_DE\" \/>\n<meta property=\"og:type\" content=\"article\" \/>\n<meta property=\"og:title\" content=\"UPVC Spring Check Valve Factory - Spring Check Valve vs Swing Check Valve\" \/>\n<meta property=\"og:description\" content=\"What is a Check Valve?
