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.
