\u00bfQu\u00e9 es la v\u00e1lvula de compuerta con sello de fuelle?<\/h2>\r\n\r\n\r\n\r\n\r\nUna v\u00e1lvula de compuerta con sello de fuelle es una v\u00e1lvula especialmente dise\u00f1ada para su uso en industrias que trabajan con medios peligrosos donde incluso las fugas m\u00e1s peque\u00f1as pueden ser extremadamente cr\u00edticas. Con el crecimiento exponencial de nuevas industrias, como la qu\u00edmica y la nuclear, hay una creciente abundancia de medios inflamables, peligrosos, extremadamente venenosos y t\u00f3xicos que fluyen a trav\u00e9s de las tuber\u00edas. Esto crea un alto riesgo de fugas, explosiones y riesgos para la salud. Por lo tanto, las v\u00e1lvulas utilizadas en tales tuber\u00edas y sistemas tienen requisitos estrictos espec\u00edficos de fugas y sellado.\r\n\r\n\r\n\r\n\r\n

Construcci\u00f3n de fuelle de v\u00e1lvula de compuerta sellada con fuelle<\/h2>\r\n\r\n\r\n\r\n\r\nEl cartucho de fuelle est\u00e1 soldado tanto al casquete de la v\u00e1lvula como al v\u00e1stago de la v\u00e1lvula. El cartucho de fuelle tiene varias circunvoluciones y estas circunvoluciones se comprimen o expanden dependiendo del movimiento del v\u00e1stago de la v\u00e1lvula. (Cient\u00edficamente hablando, el fuelle se comprime cuando la v\u00e1lvula est\u00e1 en posici\u00f3n abierta y se expande cuando la v\u00e1lvula est\u00e1 en posici\u00f3n cerrada). Es importante instalar correctamente los cuerpos de las v\u00e1lvulas. El fuelle se puede sellar a las v\u00e1lvulas de dos maneras diferentes. En primer lugar, el fuelle se puede soldar al v\u00e1stago de la v\u00e1lvula en la parte superior y al cuerpo de la v\u00e1lvula en la parte inferior. En este caso, el fluido del proceso est\u00e1 contenido dentro del fuelle o, en el segundo m\u00e9todo, el fuelle est\u00e1 soldado al v\u00e1stago de la v\u00e1lvula en la parte inferior y al cuerpo en la parte superior. En este caso, el fluido de proceso est\u00e1 contenido en la regi\u00f3n anular entre el casquete de la v\u00e1lvula y el fuelle (desde el exterior).\r\n\r\n\r\n\r\n\r\n\r\nEl fuelle es un componente cr\u00edtico y forma el coraz\u00f3n de las v\u00e1lvulas de sello de fuelle. Para evitar cualquier torsi\u00f3n del fuelle, la v\u00e1lvula debe tener un v\u00e1stago con movimiento \u00fanicamente lineal. Esto se puede lograr usando la llamada tuerca de manguito en la porci\u00f3n del yugo del casquete de la v\u00e1lvula. Se coloca un volante en la tuerca de manguito que transfiere efectivamente un movimiento giratorio del volante a un movimiento lineal en el v\u00e1stago de la v\u00e1lvula.\r\n\r\n\r\n\r\n\r\n

Tipos de fuelle de v\u00e1lvula de compuerta con sello de fuelle<\/h2>\r\n\r\n\r\n\r\n\r\nThere are two main types of bellow.. the Forged Bellow and the Welded Bellow. Formed-type bellows are made by rolling a flat sheet (thin wall foil) into a tube which is then longitudinally fusion welded. This tube is subsequently mechanically or hydrostatically formed into a bellow with rounded and widely spaced folds. The welded leaf type bellow is made by welding washer-like plates of thin metal together at both the inner and outer circumference of the washers - like plates. A welded leaf bellow has more folds per unit length as compared to forged bellows. Thus, for the same stroke length, forged bellows are two to three times longer than their welded leaf counterparts.\r\n\r\n\r\n\r\n\r\n\r\nSeg\u00fan se informa, los fuelles forjados mec\u00e1nicamente fallan en puntos aleatorios, mientras que la hoja soldada generalmente falla en una soldadura o cerca de ella. Para garantizar una penetraci\u00f3n completa de los extremos del fuelle y la soldadura del collar final, es aconsejable fabricar mediante soldadura por microplasma.\r\n\r\n\r\n\r\n\r\n

Dise\u00f1o de fuelle de v\u00e1lvula de compuerta con sello de fuelle<\/h2>\r\n\r\n\r\n\r\n\r\nEl dise\u00f1o de fuelle de m\u00faltiples capas se prefiere para manejar fluidos a alta presi\u00f3n (generalmente dos o tres capas de la pared met\u00e1lica). Un fuelle de dos capas puede aumentar su clasificaci\u00f3n de presi\u00f3n de 80% a 100% en comparaci\u00f3n con un fuelle de una sola capa del mismo espesor. Alternativamente, si se utiliza un fuelle de una sola capa de un espesor equivalente a una clasificaci\u00f3n de presi\u00f3n de un fuelle de dos capas, se reduce la longitud de la carrera. Por lo tanto, un dise\u00f1o de fuelle de varias capas ofrece una clara ventaja sobre un fuelle de una sola capa. Est\u00e1 claro que el fuelle est\u00e1 sujeto a fatiga del metal y esta fatiga puede inducir fallas en la soldadura. La vida a fatiga del fuelle se ve afectada por el material de construcci\u00f3n, la t\u00e9cnica de fabricaci\u00f3n, la longitud y la frecuencia de la carrera, adem\u00e1s de los par\u00e1metros habituales como la temperatura y la presi\u00f3n del fluido.\r\n\r\n\r\n\r\n\r\n

Bellow sealed valves are used to prevent leakage of any toxic chemical into the atmosphere. The bellow can be supplied in different materials like 316Ti, 321, C276, or Alloy 625. Body material can be selected from all available materials. Leakage at various points in pipelines found in chemical plants creates emissions. All such leakage points can be detected using various methods and instruments and should be noted by the plant engineer. Critical leakage points include flanged gasket joints and the Valve\/pump gland packing, etc. Today the chemical process industry is gearing itself towards safer technology for better environmental protection and it has become every process engineer’s responsibility to design plants that limit damage to the environment through the prevention of leakage of any toxic chemicals. GET BELLOW SEAL GATE VALVE PRICE What is Bellow Seal Gate Valve? A Bellow Seal Gate Valve is a specially designed valve suitable for use in industries dealing with a hazardous medium where even minute leakages can be extremely critical. With the exponential growth of new industries such as the chemical and nuclear industries, there is a growing abundance of flammable, hazardous, extremely poisonous, and toxic media flowing through the pipelines. This creates a high risk of leakage, explosion, and health hazards. So, the valves used in such pipes and systems have specific stringent leakage and sealing requirements. Bellow Construction of Bellow Sealed Gate Valve The bellow cartridge is welded to both the Valve Bonnet and the Valve stem. The bellow cartridge has a number of convolutions and these convolutions become compressed or expanded depending upon the movement of the Valve stem. (Scientifically speaking the bellow gets compressed when the Valve is in the open position and expanded when the Valve is in the closed condition). It is important to properly install the Valve bodies. The bellow can be sealed to the Valves in two different ways. Firstly, the bellow can be welded to the Valve stem at the top and the Valve body at the bottom. In this case, the process fluid is contained inside the bellow, or in the second method the bellow is welded to the Valve stem at the bottom and the body on the top. In this case, the process fluid is contained in the annular region between the Valve Bonnet and bellow (from the outside). The bellow is a critical component and forms the heart of the bellow seal Valves. To avoid any twisting of the bellow the Valve must have a stem with linear movement only. This can be achieved using a so-called sleeve nut at the Yoke portion of the Valve Bonnet. A handwheel is fitted onto the sleeve-nut which effectively transfers a rotary motion of the handwheel into a linear motion in the Valve stem. Bellow types of Bellow Seal Gate Valve There are two main types of bellow.. the Forged Bellow and the Welded Bellow. Formed-type bellows are made by rolling a flat sheet (thin wall foil) into a tube which is then longitudinally fusion welded. This tube is subsequently mechanically or hydrostatically formed into a bellow with rounded and widely spaced folds. The welded leaf type bellow is made by welding washer-like plates of thin metal together at both the inner and outer circumference of the washers – like plates. A welded leaf bellow has more folds per unit length as compared to forged bellows. Thus, for the same stroke length, forged bellows are two to three times longer than their welded leaf counterparts. Reportedly, mechanically forged bellows fail at random spots, while the welded leaf usually fails at or near a weld. To ensure full penetration of bellow ends and end coller welding it is advisable to fabricate using micro plasma welding. Bellow Design of Bellows Seal Gate Valve The multi-ply bellow design is preferred for handling higher-pressure fluids (generally two or three plies of the metal wall). A two-ply bellow can increase its pressure rating by 80% to 100% as compared to a single ply bellow of the same thickness. Alternatively, if a single ply bellow of a thickness equivalent to a pressure rating of a two-ply bellow is used, the stroke length is reduced. Thus, a multi-ply bellow design offers a distinct advantage over a single ply bellow. It is clear that the bellow is subject to metal fatigue and this fatigue can induce weld failure. The bellow fatigue life is affected by the material of construction, fabrication technique, stroke length, and stroke frequency, in addition to the usual parameters such as fluid temperature and pressure.
