Was ist das Auswahlprinzip f\u00fcr Absperrventile aus geschmiedetem Stahl?<\/h1>\r\n

Das Auswahlprinzip f\u00fcr Absperrventile aus geschmiedetem Stahl lautet:<\/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. An der Rohrleitung, wo der Str\u00f6mungswiderstand in der Rohrleitung nicht streng ist. Das hei\u00dft, der Ort, an dem der Druckverlust nicht ber\u00fccksichtigt wird.<\/li>\r\n
  3. Kleine Ventile k\u00f6nnen mit Nadelventilen, Instrumentenventilen, Probenahmeventilen, Manometerventilen usw. verwendet werden.<\/li>\r\n<\/ol>\r\n\r\n\r\n\r\n

    4. Es gibt eine Durchflussregelung oder Druckregelung, aber die Einstellgenauigkeit ist nicht hoch und der Rohrleitungsdurchmesser ist relativ klein, beispielsweise sollte der Nenndurchmesser einer Rohrleitung \u2264 50 mm verwendet werden.<\/p>\r\n\r\n\r\n\r\n

      \r\n
    1. F\u00fcr kleine chemische D\u00fcngemittel und gro\u00dfe chemische D\u00fcngemittel in der synthetischen Industrieproduktion sollten Hochdruck-Winkelabsperrventile oder Hochdruck-Winkeldrosselventile mit Nenndruck PN160 Nenndruck 16 MPa oder PN320 Nenndruck 32 MPa verwendet werden.<\/li>\r\n
    2. In der Desilikonisierungswerkstatt und der einfachen Verkokungspipeline bei der Herstellung von Aluminiumoxid nach dem Bayer-Verfahren ist es einfach, den DC-Typ auszuw\u00e4hlen
      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. Bei Wasserversorgungs- und Heizungsprojekten im St\u00e4dtebau ist es bekannt, kleinere Rohrleitungen zu durchlaufen, und es k\u00f6nnen Absperrventile, Ausgleichsventile oder Kolbenventile verwendet werden, beispielsweise f\u00fcr Rohrleitungen mit einem Nenndurchmesser von weniger als 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":"
