Bucket Type Steam Trap Animation

These are mechanical type of steam traps working on the principle of buoyancy.

Bucket type steam trap animation.

Liquid expansion steam traps the liquid expansion steam trap employs a liquid expansion device to discharge condensate at a predefined temperature. Up to 4 400 lb hr 2 000 kg hr. Request a quote request a steam system assessment. The inverted bucket steam trap is shown in figure 11 3 3.

Condensate causes the bucket to lose buoyancy and sink opening the valve and allowing the removal of the condensate. An essential part of the trap is the small air vent hole in the top of the bucket. Up to 20 000 lb hr 9 072 kg hr. The weep hole is usually small enough to prevent significant steam loss but it removes only a limited amount of air which can hinder system start up or heat transfer on equipment.

In contrast inverted bucket type traps typically include an internal weep hole to bleed off steam or air continuously and with each cycle. 800 813 series inverted bucket steam traps. A steam trap should. Most steam traps pass non condensable gases like air while remaining tight to live steam.

To review a specific inverted bucket steam trap select a series and go to the menu. 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. Discharge condensate immediately and completely.

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. When steam or air enters the bucket the bucket gains buoyancy and closes the valve. Inverted bucket traps are the most robust type of the mechanical traps. Inverted bucket steam trap.

As its name implies the mechanism consists of an inverted bucket which is attached by a lever to a valve. The bucket trap uses an inverted bucket as a float device and a linkage connects the bucket to the valve head. 200 series inverted bucket steam traps.
