Bucket Steam Trap

The inverted bucket is the most reliable steam trap operating principle known.

Bucket steam trap. Working of a inverted bucket steam trap. Energy efficient because it s so reliable. With check valve fitted in the inlet they can be used with superheated steam. Inverted bucket traps are the most robust type of the mechanical traps.

Startup only condensate open position. Able to resist waterhammer. As the bucket moves up and down in the condensate a linkage connected to the bucket closes or opens a discharge valve trapping the condensate or allowing it to escape. In inverted bucket steam traps the bucket within the trap is attached to a lever that opens and closes the trap valve in response to the bucket s motion.

Condensate causes the bucket to lose buoyancy and sink opening the valve and allowing the removal of the condensate. Discharge condensate as soon as it is formed unless it is desirable to use the sensible heat of the liquid condensate. The bucket trap uses an inverted bucket as a float device and a linkage connects the bucket to the valve head. A steam trap is a device used to discharge condensates and non condensable gases with a negligible consumption or loss of live steam steam traps are nothing more than automatic valves they open close or modulate automatically.

Inverted bucket traps are the most robust type of the mechanical traps. 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. Liquid expansion steam traps. Inverted bucket steam trap is a density operated steam trap which operates on the difference in density between steam and water.

When steam or air enters the bucket the bucket gains buoyancy and closes the valve. Inverted bucket steam traps. When steam or air flows into the underside of the inverted bucket and condensate surrounds it on the outside the steam causes the bucket to become buoyant and rise. Inverted bucket traps rely on the density difference between steam and water to drain condensate as it forms.

The three important functions of steam traps are. The inverted bucket within the trap will rest on the bottom of the trap body keeping the valve open and allowing condensate to be discharged figure a in the top of the bucket there is a small bleed hole which allows air to escape from inside the bucket and exit through the outlet port figure b when steam arrives through the inlet of the trap it fills the inverted.
