Product overview
881F Inverted Bucket Steam
TrapWhen steam enters the inverted bucket, the upside-down bucket
generates upward buoyancy, and the inverted bucket is connected to the
lever to drive the valve core to close the valve. There is a small hole
on the inverted bucket, which can automatically exhaust the air, when
part of the steam is discharged from the small hole, the other part of
the steam produces condensate, the inverted bucket loses buoyancy and
sinks, and the inverted bucket is connected to the lever to drive the
valve core to open the valve. When the steam enters the inverted bucket
again, the valve closes again, circulates and drains intermittently.
How it works
Inverted (placed) bucket steam trap It is the use of condensate and
steam density difference working principle, the internal structure is
connected by the lever system to the inverted bucket, overcome the steam
pressure switch inverted bucket trap inside is an inverted bucket for
the level sensitive parts, the opening of the inverted bucket down. When
the unit is first started, air and low-temperature condensate appear in
the pipe, and the trap is fully open, the air and low-temperature
condensate are quickly discharged, and the device quickly increases the
temperature. When the steam enters the inverted barrel, the inverted
barrel generates upward buoyancy, and the inverted barrel is connected
to the lever to drive the valve core to close the valve. There is a
small hole on the inverted bucket, which can automatically exhaust air,
when a part of the steam is discharged from the small hole, the other
part of the steam produces condensate, the inverted bucket loses
buoyancy and sinks, and the inverted bucket is connected to the lever to
drive the valve core to open the valve. When the steam enters the
inverted bucket again, the valve closes again, circulates and drains
intermittently.
