Armstrong inverted bucket
steam traps only have two moving
parts - the valve lever assembly and
the bucket. That means no
fixed points, no complicated
linkages. Nothing to stick,
bind or clog.
Armstrong inverted bucket steam
traps open and close based on the
difference in density between
condensate and steam-the inverted
bucket principle. They open
and close gently, minimizing wear.
This simple fact means that inverted
buckets are subject to less wear
than some other types of traps.
In fact, as an Armstrong inverted
bucket trap wears, its tight seal
actually improves. The
ball valve and seat of the Armstrong
steam trap provide essentially line
contact resulting in a tight seal
because the entire closing force is
concentrated on one narrow seating
ring.
An Armstrong inverted bucket trap
continues to operate efficiently
with use. Gradual wear
slightly increases the diameter of
the ball valve. But the more
it wears, the tighter the seal.
The ball valve seats itself deeper
as wear increases, preserving a
tight seal. |
