How it works
The inverted bucket steam trap uses
the working principle of the density difference between condensate and
steam, the internal structure is connected by a lever system to the
inverted bucket, overcome the steam pressure switch, and the inside of
the inverted bucket trap is an inverted bucket for the level sensitive
parts, and the opening of the inverted bucket is downward. 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.
Structural features
1.
Simple structure, not easy to fail. No latch or hinge structure, no
fixed wear, good energy-saving effect. Wear-resistant chromium steel
valve seat, stainless steel structure, long service life;
2. Intermittent discharge of impurities can be washed away, no dirt accumulation, automatic air exhaust;
3. There are a variety of orifice options, under different pressures, higher drainage flow can be achieved;
4. The internal parts are all installed on the valve cover, which is convenient for maintenance.
