Working Principle of the high pressure Bucket Steam Trap

High Pressure Inverted Bucket Steam Trap Working Principles.

1. Steam Trap is installed between steam heating equipment and condensation return water collector. When driving, the bucket is still on the bottom and the valve is fully open. When condensation water enters into steam trap, and then flows into the bottom of bucket to fill the valve body. When it immerses the whole bucket, the condensation water will discharge into return water collector through the fully opened valve.

2. Steam goes from the bottom of bucket into the steam trap. It occupies the top of bucket and results in buoyancy. The bucket will arise, and the lever will gradullay move toward the seat till the valve is fully closed. Air and carbon dioxide is exhausted through vent hole and gathered at the top of the steam trap. The air exhausted from the vent will condensate due to the heat dissipation of steam trap

3. When the incoming condensation water fills in the bucket, the bucket will generate a pull force toward the lever. With the rising of condensation water lever, the pull force will gradually increase till it can overcome the differential pressure to open the valve.

4. When the valve starts to open, the force of differntial pressure on disc will gradually decrease. The bucket will soon descend, and the valve will fully open. The non-condensable gas gathered on the top of steam trap will be exhausted first and the condensation water will be discharged. The outflow of water from bucket will take dirt away from steam trap. With the discharge of condensation water, the steam will reenter into the steam trap and new circle begins.
