Quel est le principe de s\u00e9lection des robinets \u00e0 soupape en acier forg\u00e9 ?<\/h1>\r\n

Le principe de s\u00e9lection des robinets \u00e0 soupape en acier forg\u00e9 est le suivant\u00a0:<\/p>\r\n\r\n\r\n\r\n

    \r\n
  1. The globe valves should be used on the pipeline or device of high temperature and high pressure medium. Such as thermal power plants, nuclear power plants, high-temperature, high-pressure pipelines of petrochemical systems.<\/li>\r\n
  2. Sur le pipeline o\u00f9 la r\u00e9sistance \u00e0 l'\u00e9coulement n'est pas stricte sur le pipeline. C\u2019est-\u00e0-dire l\u2019endroit o\u00f9 la perte de pression n\u2019est pas prise en compte.<\/li>\r\n
  3. Les petites vannes peuvent \u00eatre utilis\u00e9es avec des vannes \u00e0 pointeau, des vannes d'instrument, des vannes d'\u00e9chantillonnage, des vannes manom\u00e9triques, etc.<\/li>\r\n<\/ol>\r\n\r\n\r\n\r\n

    4, il existe un r\u00e9glage du d\u00e9bit ou une r\u00e9gulation de la pression, mais la pr\u00e9cision du r\u00e9glage n'est pas \u00e9lev\u00e9e et le diam\u00e8tre du pipeline est relativement petit, comme le diam\u00e8tre nominal du pipeline \u2264 50 mm, doit \u00eatre utilis\u00e9.<\/p>\r\n\r\n\r\n\r\n

      \r\n
    1. Pour les petits engrais chimiques et les gros engrais chimiques dans la production industrielle synth\u00e9tique, des vannes d'arr\u00eat d'angle haute pression ou des vannes d'\u00e9tranglement d'angle haute pression avec une pression nominale PN160 pression nominale 16MPa ou PN320 pression nominale 32MPa doivent \u00eatre utilis\u00e9es.<\/li>\r\n
    2. Dans l'atelier de d\u00e9siliconisation et le pipeline de cok\u00e9faction facile dans la production d'alumine selon la m\u00e9thode Bayer, il est facile de s\u00e9lectionner le type DC
      globe valves valve or the DC type throttle valve with the valve body separated, the valve seat can be removed, and the carbide seal pair.<\/li>\r\n
    3. Dans les projets d'approvisionnement en eau et de chauffage dans la construction urbaine, il est connu pour passer par des canalisations plus petites, et la vanne d'arr\u00eat, la vanne d'\u00e9quilibrage ou la vanne \u00e0 piston peuvent \u00eatre utilis\u00e9es, comme la canalisation passant le nominal inf\u00e9rieur \u00e0 150 mm.<\/li>\r\n<\/ol>\r\n\r\n\r\n\r\n

      Forged steel globe valves valves pay attention to the problem of the valve in the switch position. The ball valve is normally in the open position during maintenance and maintenance. In special cases, the maintenance is turned off. Other valves cannot be discussed in terms of opening. Forged steel globe valves must be closed during maintenance to ensure that the grease fills the seal groove along the seal. If it is open, the seal grease will fall directly into the runner or valve cavity, causing waste. When the valve is greased, the problem of grease injection is often ignored. The pressure, grease injection amount and switch position are normal during the grease filling operation. However, in order to ensure the grease filling effect of the valve, it is sometimes necessary to open or close the valve to check the lubrication effect and confirm that the valve ball or the surface of the valve is evenly lubricated.<\/p>","protected":false},"excerpt":{"rendered":"
