Operation
Take measures to prevent people from coming into direct contact with
product outlets. Failure to do so may result in burns or other injury from
the discharge of fluids.
CAUTION
(1) When condensate flows from the condensate inlet pipe through the inlet check valve
into the body of the unit, the float rises and the main valve of the trap unit is open as
shown in (A) below.
The main valve on the trap unit opens as the float rises. When P
i
> P
b
(when the
equipment pressure (P
i
) is greater than the back pressure (P
b
)), the condensate
passes through the outlet check valve and is discharged through the condensate
outlet pipe (normal trapping function).
In this case, the integrated air vent unit exhausts internal air to the outlet.
When P
i
≤
P
b
, the condensate is not discharged and collects in the body of the
unit.
(2)
When the float rises to its high level, the push rod on the snap-action unit rises
quickly, simultaneously closing the exhaust valve and opening the intake (motive
medium) valve. The pressure supplied by the motive medium causes the internal
pressure in the unit to become greater than the back pressure. The inlet check valve
closes and the outlet check valve is pushed open, thus discharging the condensate in
the unit through the outlet pipe, as shown in (B) below.
(3)
As a result of the condensate in the unit being discharged, the water level in the unit
drops and the float descends. When the float reaches its low level, the push rod on
the snap-action unit moves down quickly, simultaneously opening the exhaust valve
and closing the intake (motive medium) valve and the status reverts to that shown in
(A) below.
