Inverted bucket drain valve

The inverted bucket type steam trap operates based on the density difference between condensed water and steam. Its internal structure is connected to the inverted bucket by a lever system, overcoming the steam pressure switch. The inverted bucket type steam trap has a liquid level sensitive component inside, with the opening of the inverted bucket facing downwards. When the device is just started, air and low-temperature condensed water appear in the pipeline. At this time, the drain valve is fully open, and the air and low-temperature condensed water are quickly discharged outside the valve. The temperature of the device quickly rises. When steam enters the inverted bucket, it generates upward buoyancy, and the connecting lever of the inverted bucket drives the valve core to close the valve. There is a small hole on the inverted bucket that can automatically exhaust air. When a part of the steam is discharged from the small hole and another part of the steam produces condensed water, the inverted bucket loses buoyancy and sinks downwards. The connecting lever of the inverted bucket drives the valve core to open the valve. When the steam enters the inverted bucket again, the valve closes again, and the cycle works without interruption for drainage.
