As v\u00e1lvulas de baixa tecnologia n\u00e3o mudaram muito nos \u00faltimos 100 anos, mas as v\u00e1lvulas gaveta desempenham um papel importante nos equipamentos de refinarias, f\u00e1bricas de produtos qu\u00edmicos, usinas de energia e empresas industriais em todo o mundo.<\/p>\n\n\n\n\n\n
Sendo diversificada em tamanhos de 1\/4 a 144 polegadas, a v\u00e1lvula gaveta pode ser encontrada em todas as refinarias, f\u00e1bricas de produtos qu\u00edmicos, usinas de energia e instala\u00e7\u00f5es de fabrica\u00e7\u00e3o de plantas industriais. Sua principal finalidade \u00e9 cortar o fluxo, o que lhe d\u00e1 nomes alternativos como v\u00e1lvula de \u201ccorte\u201d ou \u201cbloqueio\u201d.<\/p>\n\n\n\n
Um fluxo de m\u00eddia quase desimpedido pode ser garantido quando ele est\u00e1 ligado. Entre muitas v\u00e1lvulas gerais, apenas a v\u00e1lvula esf\u00e9rica de poro aberto pode corresponder \u00e0 v\u00e1lvula gaveta na capacidade de fluxo. O design sim\u00e9trico e a veda\u00e7\u00e3o coordenada permitem que a v\u00e1lvula gaveta interrompa o fluxo em qualquer dire\u00e7\u00e3o. Ele pode ser feito de uma variedade de materiais e pode ser transformado em uma cole\u00e7\u00e3o diversificada, desde torneiras comuns de lat\u00e3o brilhante de 1\/2 polegada encontradas nas prateleiras de lojas de ferragens at\u00e9 uma rara de alta liga encontrada em instala\u00e7\u00f5es de usinas nucleares.<\/p>\n\n\n\n
As v\u00e1lvulas gaveta n\u00e3o podem ser operadas em uma posi\u00e7\u00e3o parcialmente aberta ou usadas para fins de regula\u00e7\u00e3o devido ao potencial dano \u00e0 superf\u00edcie de assentamento. Por qu\u00ea ent\u00e3o? A raz\u00e3o s\u00e3o os arranh\u00f5es causados pelo dispositivo de desligamento (o port\u00e3o ou a cunha) balan\u00e7ando entre os dois assentos parcialmente abertos.<\/p>\n\n\n\n
Por mais semelhante que seja sua apar\u00eancia externa, sua estrutura interna \u00e9 diferente uma da outra. A maioria das v\u00e1lvulas gaveta consiste em um corpo, uma tampa e um dispositivo de desligamento (uma gaveta ou uma cunha). O dispositivo de desligamento \u00e9 conectado \u00e0 haste, que se estende atrav\u00e9s do castelo e finalmente chega ao volante ou a outros operadores de haste. Ao redor da haste, o material de veda\u00e7\u00e3o pressurizado na caixa de empanque suporta a press\u00e3o.<\/p>\n\n\n\n
Embora as v\u00e1lvulas gaveta possam ser feitas de metais que v\u00e3o do alum\u00ednio ao zirc\u00f4nio na tabela peri\u00f3dica qu\u00edmica e variedades de pl\u00e1sticos de engenharia, os mais comuns s\u00e3o a\u00e7o, ferro e bronze.<\/p>\n\n\n\n
Bronze ou lat\u00e3o possuem excelente usinabilidade com menor custo. Pela sua baixa resist\u00eancia e dureza, o bonze \u00e9 usin\u00e1vel, mas adequado apenas para aplica\u00e7\u00f5es de baixa press\u00e3o. As v\u00e1lvulas de bronze s\u00e3o usadas principalmente em tubula\u00e7\u00f5es de \u00e1gua e linhas de servi\u00e7o com press\u00f5es de 300 PSI ou menos.<\/p>\n\n\n\n
A resist\u00eancia da v\u00e1lvula de ferro est\u00e1 entre a das v\u00e1lvulas de bronze e de a\u00e7o. O ferro \u00e9 dif\u00edcil de manusear, mas o ferro fundido \u00e9 relativamente f\u00e1cil. As v\u00e1lvulas de ferro s\u00e3o geralmente feitas de dois materiais, ferro cinzento e ferro male\u00e1vel. Com uma elevada percentagem de carbono e uma excelente resist\u00eancia \u00e0 ferrugem, as v\u00e1lvulas de ferro s\u00e3o mais adequadas para aplica\u00e7\u00f5es subterr\u00e2neas do que as v\u00e1lvulas de a\u00e7o.<\/p>\n\n\n\n
Para v\u00e1lvulas industriais, os materiais de a\u00e7o variam desde o grau mais baixo \u201cWCB\u201d at\u00e9 ligas de a\u00e7o de cromo\/molibd\u00eanio. Ao contr\u00e1rio do lat\u00e3o, bronze ou ferro, a maior parte do a\u00e7o de baixa liga \u00e9 sold\u00e1vel, o que torna as v\u00e1lvulas de a\u00e7o f\u00e1ceis de serem reparadas, soldadas novamente e, em alguns casos, fabricadas. A v\u00e1lvula gaveta tamb\u00e9m pode ser feita de ligas raras, como tit\u00e2nio e zirc\u00f4nio na tabela peri\u00f3dica.<\/p>\n\n\n\n\n

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).\r\n\r\n\r\n\r\n\r\n
How does a Gate Valve work?<\/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
Where are Gate Valves Used?<\/h2>\r\n\r\n\r\n\r\n\r\nGate 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.\r\n\r\n\r\n\r\n\r\n
Advantages of Gate Valves<\/h2>\r\n\r\n\r\n\r\n
\r\n \t
Disadvantages of Gate Valves<\/h2>\r\n\r\n\r\n\r\n
\r\n \t
Construction of Gate Valves<\/h2>\r\n\r\n\r\n\r\n\r\nCommon gate valves are actuated by a threaded stem that connects the actuator (e.g. handwheel or motor) to the gate. They are characterized as having either a rising or a non-rising stem, depending on which end of the stem is threaded. Rising stems are fixed to the gate and rise and lower together as the valve is operated, providing a visual indication of valve position. The actuator is attached to a nut that is rotated around the threaded stem to move it. Non rising stem valves are fixed to, and rotate with, the actuator, and are threaded into the gate. They may have a pointer threaded onto the stem to indicate valve position since the gate's motion is concealed inside the valve. Non rising stems are used where vertical space is limited.\r\n\r\n\r\n\r\n\r\n\r\nGate valves can be actuated manually (handwheel) or electrically using a high torque motor.\r\n\r\n\r\n\r\n\r\n\r\nThe sliding gate (disc) can be wedge-shaped (tapered) or parallel-shaped. Wedge shape designs include solid, flexible, and split wedge designs.\r\n\r\n\r\n\r\n\r\n\r\nSeat rings are used to make the replacement of a worn\/leaking seat easier. Seat rings have a screw thread on the reverse side which can be screwed into the main valve body, the flat surface on the opposite side is the seating surface area that presses against the disc. If seat rings are not used, it is possible to machine a flat seat on the main valve body itself, unfortunately, this makes replacing the seat impossible and the seat can only be machined a few times before the entire valve must be replaced.\r\n\r\n\r\n\r\n\r\n\r\nGate valve bonnets are often constructed of cast iron. Cast iron is brittle and this makes the bonnet prone to cracking. Special care should be taken when handling and maintaining valves with cast iron bonnets.\r\n\r\n\r\n\r\n\r\n\r\nAs the stem penetrates through the valve bonnet, it is necessary to install a sealing gland to prevent leakage from occurring through the gap between the stem and bonnet; sealing is usually achieved using the fibrous packing material.\r\n\r\n\r\n\r\n\r\n\r\nFlanges are installed on the suction and discharge side of the valve so that piping can be easily connected.\r\n\r\n\r\n\r\n\r\n
Gate Valve Types<\/h2>\r\n\r\n\r\n\r\n\r\nThe gate comes in various designs and technologies to produce effective sealing for differing applications.\r\n\r\n\r\n\r\n\r\n\r\nKnife gate valve\r\n\r\n\r\n\r\n\r\n\r\nA knife gate valve is used for thick fluids and dry bulk solids. The gate is only one piece of metal, which is typically pointed like a knife. These valves are self-cleaning as they pass the seat rings every time they open and close.\r\n\r\n\r\n\r\n\r\n
Wedge Gate Valve<\/h3>\r\n\r\n\r\n\r\n\r\nA wedge gate valve has a gate in the shape of a wedge that sits on two inclined seats. In addition to the primary force created by fluid pressure, a high wedging force on the seats created by the stem tightening assists with the sealing. The wedge-shaped gate does not stick to the seat in case of high fluid differential pressure and has an increased service life due to less \"rubbing\" on the seats. However, wedge-shaped gate valves have an additional compression load on the seats that may result in thermal binding and restricted valve opening due to expansion.\r\n\r\n\r\n\r\n\r\n
Parallel Slide Gate Valve<\/h3>\r\n\r\n\r\n\r\n\r\nA parallel slide gate valve has a flat gate and seats parallel to it. Parallel slide gate valves use line pressure and positioning to make a tight seal. Flat gates consist of two pieces and have a spring in the middle. The spring pushes the pieces towards the seats for enhanced sealing. Due to their inherent design, parallel gate valves have a safety advantage in higher-temperature applications. Furthermore, since there is no wedging action in parallel gates, closing torques are comparatively smaller, resulting in smaller, less expensive actuators or less manual effort. Due to their sliding into position, parallel gates keep dirt away from the seating surfaces.\r\n\r\n\r\n\r\n\r\n
Slab Gate Valve<\/h3>\r\n\r\n\r\n\r\n\r\nSlab gates, also called through-conduit gate valves, are one-unit gates that include a bore-size hole. The bore is in line with the two-seat rings in the open state. This alignment creates a smooth flow with minimal turbulence. This unique design allows for minimal pressure loss in the system and is perfect for the transportation of crude oil and natural gas liquids (NGLs). The valve seats remain clean. However, the disc cavity can capture foreign material. Therefore, the cavity typically has a built-in plug for maintenance purposes of draining the accumulated foreign material.\r\n\r\n\r\n\r\n\r\n
Parallel Expanding Gate Valve<\/h3>\r\n\r\n\r\n\r\n\r\nExpanding gate valves have two slab gates matched together that provide sealing through the mechanical expansion of the gate, as seen in Figure 5. When lifted, both of the slab gate's cavities allow the media to flow. The upward force on one slab and the stoppage of the second slab, by a step in the valve body, allows for outward mechanical expansion for a proper seal. When closed, the slab gates block the media flow, and the downward force (stem) on one slab and upward force (step in valve body) allows for outward mechanical expansion for a proper seal.\r\n\r\n\r\n\r\n\r\n\r\nThese valves provide an effective seal simultaneously for both upstream and downstream seats. This seal makes them ideal for applications like isolation valves in power plants, block valves in process systems, and high-temperature valves in refineries.\r\n\r\n\r\n\r\n\r\n
Metal seated vs Resilient Seated Gate Valves<\/h2>\r\n\r\n\r\n\r\n\r\nBefore the resilient seated gate valve was introduced to the market, gate valves with a metal seated wedge were widely used. The conical wedge design and angular sealing devices of a metal seated wedge require a depression in the valve bottom to ensure a tight closure. Herewith, sand and pebbles are embedded in the bore. The pipe system will never be completely free from impurities regardless of how thoroughly the pipe is flushed upon installation or repair. Thus, any metal wedge will eventually lose its ability to be drop-tight.\r\n\r\n\r\n\r\n\r\n\r\nA resilient seated gate valve has a plain valve bottom allowing free passage for sand and pebbles in the valve. If impurities pass as the valve closes, the rubber surface will close around the impurities while the valve is closed. A high-quality rubber compound absorbs the impurities as the valve closes, and the impurities will be flushed away when the valve is opened again. The rubber surface will regain its original shape by securing a drop-tight sealing.\r\n\r\n\r\n\r\n\r\n\r\nThe vast majority of gate valves are resilient seated, however, metal seated gate valves are still requested in some markets, so they are still part of our range for water supply and wastewater treatment.\r\n\r\n","parent":0,"count":8,"filter":"raw"},{"term_id":3170,"name":"Gate Valve \u0e04\u0e37\u0e2d \u0e2d\u0e30\u0e44\u0e23","slug":"%e0%b8%84%e0%b8%b7%e0%b8%ad-%e0%b8%ad%e0%b8%b0%e0%b9%84%e0%b8%a3","term_group":0,"term_taxonomy_id":3170,"taxonomy":"post_tag","description":"\r\n\r\n\r\n\r\nGET GATE VALVE \u0e04\u0e37\u0e2d \u0e2d\u0e30\u0e44\u0e23 INFORMATION<\/strong><\/a>\r\n\r\n\r\n\r\n\r\n
