Steam Traps

Inverted bucket steam traps

The inverted bucket is the most reliable steam trap operating principle known. The heart of its simple design is a unique leverage system that multiplies the force provided by the bucket to open the valve against pressure. inverted bucket steam traps open and close based on the difference in density between condensate and steam-the inverted bucket principle. They open and close gently, minimizing wear. This simple fact means that inverted buckets are subject to less wear than some other types of traps.Inverted Bucket Steam Traps belong to the family of mechanical traps. They operate on the difference in density between steam and water.

2.Inverted bucket steam traps Working principle
Inverted bucket steam trap using the density contrast of condensate water and steam to work. The internal structure is lever system connect with inverted bucket. The inverted bucket steam trap has a down facing inverted bucket as hydraulic sensor in order to overcome the steam pressure. When the device starts, in the pipeline appears the air and the low temperature condensate water. The Inverted bucket steam trap is full opening in this time, the condensate water rapidly discharges, the temperature rises quickly. The steam enters into inverted bucket which will produce upward buoyancy and the lever impetus valve core to close the valve. It has one hole in the inverted bucket which releases the air automatelly. When a little of steam discharges from the hole, the remainder steam will form condensate water. The inverted bucket loses the buoyancy and downward, the lever impetus the valve core to open the valve. When the steam enters into the inverted bucket, the valve closed again, circulate working, interrupted draining water.

3.Water discharge capacity of the inverted bucket type steam trap.(KG/HR) when you select the model,pls take 2-3 times of safety factor into consideration.

5.The essential to order

1. According the maximum steam consuming capacity multiply the selected magnification of steam equipment (2-3 times) in order to choose the displacement of trap for the maximum condensate water capacity 
2.The maximum differential pressure of trap (The front operating pressure minus the back pressure of valve ) should be noted if has back pressure. 
3.The maximum operating temperature of the trap
4.The operating condition of the trap
5.Ends connection6.Body material
