The invention discloses a pneumatic
high pressure regulating valve. The pneumatic
high pressure regulating valve comprises an executing mechanism and a valve part which is arranged under the executing mechanism, wherein the valve part comprises a valve body; an inlet runner and an outlet runner are arranged in the valve body; and an angle formed between the inlet runner and the outlet runner is 120 degrees. The pneumatic
high pressure regulating valve disclosed by the invention has the advantages as follows: as the plurality of special structural designs are adopted, applicable
pressure difference of the valve is very high and
cavitation phenomenon is completely eliminated; sensitive action and high response speed are obtained and the pneumatic high pressure regulating valve can be freely closed and opened and can be tightly closed when meeting very high
fluid pressure difference; a side
flange and a valve cage of the specially designed valve body can be also used for guiding fluid, buffering
fluid pressure and protecting a valve core against being damaged by fluid
ablation,
flash evaporation and
cavitation; meanwhile, noises can be also reduced; simple and rapid maintenance and low cost are also obtained; the service life is obviously prolonged; and the pneumatic high pressure regulating valve is especially suitable for automatically controlling high temperature and high pressure mediums with high pressure differences and is safe and reliable in use. The pneumatic high pressure regulating valve disclosed by the invention is especially incomparable with other valves in advantages when being used for places with high pressure
urea and other easily crystallized mediums.
