Care este principiul de selec\u021bie pentru supapele cu glob din o\u021bel forjat?<\/h1>\r\n

Principiul de selec\u021bie pentru supapele cu glob din o\u021bel forjat este:<\/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. Pe conduct\u0103 unde rezisten\u021ba la curgere nu este strict\u0103 pe conduct\u0103. Adic\u0103 locul unde nu se ia \u00een considerare pierderea de presiune.<\/li>\r\n
  3. Supapele mici pot fi utilizate cu supape cu ac, supape de instrument, supape de prelevare de probe, supape de manometru etc.<\/li>\r\n<\/ol>\r\n\r\n\r\n\r\n

    4, exist\u0103 reglarea debitului sau reglarea presiunii, dar precizia de reglare nu este mare, iar diametrul conductei este relativ mic, cum ar fi diametrul nominal de conduct\u0103 \u2264 50 mm.<\/p>\r\n\r\n\r\n\r\n

      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

      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":"
