200 series inverted bucket steam traps.
Condensate causes the bucket to lose buoyancy and sink opening the valve and allowing the removal of the condensate.
Figure 11 3 3 shows the method of operation.
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.

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.
Discharge condensate immediately and completely.
A steam trap should.
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.
Most steam traps pass non condensable gases like air while remaining tight to live steam.
Inverted bucket traps are the most robust type of the mechanical traps.
Initially the bucket is resting at the bottom of the steam trap and the valve seat is wide open.
The bucket trap uses an inverted bucket as a float device and a linkage connects the bucket to the valve head.
The inverted bucket steam trap is shown in figure 11 3 3.
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.
An essential part of the trap is the small air vent hole in the top of the bucket.
As its name implies the mechanism consists of an inverted bucket which is attached by a lever to a valve.
When steam or air enters the bucket the bucket gains buoyancy and closes the valve.
Up to 4 400 lb hr 2 000 kg hr.
These are mechanical type of steam traps working on the principle of buoyancy.
Up to 20 000 lb hr 9 072 kg hr.
At star up air will enter the steam trap and will be discharged out through the bleed hole.
