Bucket Type Steam Trap Animation

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

Bucket type steam trap animation. When steam or air enters the bucket the bucket gains buoyancy and closes the valve. Initially the bucket is resting at the bottom of the steam trap and the valve seat is wide open. 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. 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.

In contrast inverted bucket type traps typically include an internal weep hole to bleed off steam or air continuously and with each cycle. An essential part of the trap is the small air vent hole in the top of the bucket. To review a specific inverted bucket steam trap select a series and go to the menu. Liquid expansion steam traps the liquid expansion steam trap employs a liquid expansion device to discharge condensate at a predefined temperature.

A steam trap should. As its name implies the mechanism consists of an inverted bucket which is attached by a lever to a valve. A steam trap is a self contained valve which automatically drains the condensate from a steam containing enclosure while remaining tight to live steam or if necessary allowing steam to flow at a controlled or adjusted rate. Condensate causes the bucket to lose buoyancy and sink opening the valve and allowing the removal of the condensate.

Discharge condensate immediately and completely. Up to 4 400 lb hr 2 000 kg hr. The inverted bucket steam trap is shown in figure 11 3 3. At star up air will enter the steam trap and will be discharged out through the bleed hole.

Figure 11 3 3 shows the method of operation. 200 series inverted bucket steam traps. Request a quote request a steam system assessment. Inverted bucket traps are the most robust type of the mechanical traps.

800 813 series inverted bucket steam traps. Most steam traps pass non condensable gases like air while remaining tight to live steam. Up to 20 000 lb hr 9 072 kg hr.
