Discharge condensate immediately and completely. Inverted bucket traps are the most robust type of the mechanical traps. Liquid expansion steam traps the liquid expansion steam trap employs a liquid expansion device to discharge condensate at a predefined temperature. The inverted bucket steam trap is shown in figure 11 3 3.

Figure 11 3 3 shows the method of operation. Up to 4 400 lb hr 2 000 kg hr. A steam trap should. When steam or air enters the bucket the bucket gains buoyancy and closes the valve.

These are mechanical type of steam traps working on the principle of buoyancy. As its name implies the mechanism consists of an inverted bucket which is attached by a lever to a valve. At star up air will enter the steam trap and will be discharged out through the bleed hole. 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.

Inverted bucket steam trap. Most steam traps pass non condensable gases like air while remaining tight to live steam. Request a quote request a steam system assessment. 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. Condensate causes the bucket to lose buoyancy and sink opening the valve and allowing the removal of the condensate. 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. 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. 800 813 series inverted bucket steam traps.
