Operating Principles (for IR2000)
Construction
When the setting knob is turned, the nozzle is
closed by the flapper allowing the supply air that
flows in from the upstream side to pass through the
fixed orifice and to act on diaphragm B as nozzle
back pressure, the main valve is pushed down by
the generated force and the supply pressure flows
out to the downstream side. The air pressure that
flows in acts on diaphragm C and while opposing
the force generated by diaphragm B, it also acts on
diaphragm A opposing the compression force of the
setting spring and becomes the set pressure. If the
set pressure rises too high, diaphragm A is pushed
up, the interval between the flapper and the nozzle
widens, the nozzle back pressure drops, the
balance of diaphragms B and C is broken, the main
valve closes, the exhaust valve opens and the
excess pressure from the downstream side is
discharged to the atmosphere. In this way fine
pressure
nozzle/flapper style pilot mechanism, and precise
pressure adjustment is performed.
