Bucket Steam Trap

The bucket trap uses an inverted bucket as a float device and a linkage connects the bucket to the valve head.

Bucket steam trap.

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. Startup only condensate open position. The liquid expansion steam trap employs a liquid expansion device to discharge condensate at a predefined temperature.

Inverted bucket steam traps. Inverted bucket traps are the most robust type of the mechanical traps. Liquid expansion steam traps. The three important functions of steam traps are.

With check valve fitted in the inlet they can be used with superheated steam. 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. The inverted bucket is the most reliable steam trap operating principle known. Working of a inverted bucket steam trap.

When steam or air enters the bucket the bucket gains buoyancy and closes the valve. Energy efficient because it s so reliable. Inverted bucket steam trap is a density operated steam trap which operates on the difference in density between steam and water. An inverted bucket floats in condensate that surrounds the bucket.

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. Condensate causes the bucket to lose buoyancy and sink opening the valve and allowing the removal of the condensate. 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.

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. Inverted bucket traps rely on the density difference between steam and water to drain condensate as it forms.
