Bucket Steam Traps

Size 1 2 to 1 bspt.

Bucket steam traps.

Air is vented through the small hole in the top of the inverted bucket. 970 and 990f series inverted bucket steam trap have replaced the 980 series. Liquid expansion steam traps the liquid expansion steam trap employs a liquid expansion device to discharge condensate at a predefined temperature. Float traps can have a mechanical linkage or can seal the trap through use of the float itself.

Temperature 0 to 220 c. Inverted bucket steam traps inverted bucket traps are the most robust type of the mechanical traps. Mechanical traps will have a bucket or float that rises and falls in relation to condensate level and this usually has a mechanical linkage attached that opens and closes the valve. Ductile iron inverted bucket steam trap with integral strainer.

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. A contrasting characteristic of both the float and thermostatic and inverted bucket is the. This simple fact means that inverted buckets are subject to less wear than some other types of traps. The orifice which is located in the upper part of the body is controlled by the vertical movement of the inverted bucket.

In this position the bucket will cause the trap valve to close. Discharge orifices must be sized by differential pressure. As with inverted bucket traps float and thermostatic traps rely on a fixed force the buoyancy of the float. Inverted bucket and float traps are examples of mechanical traps.

They are also resistant to water hammer. They open and close gently minimizing wear. The inverted bucket steam trap is very robust unaffected by corrosion and has an excellent ability to handle dirt. Armstrong inverted bucket steam traps open and close based on the difference in density between condensate and steam the inverted bucket principle.

Pressure range 0 to 16 bar. 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. Inverted bucket traps drain continuously although discharging intermittently allowing no condensate backup. Mechanical traps operate in direct relationship to condensate levels present in the body of the steam trap.

There is a vent hole in the top of the bucket that allows a small amount of the vapor to be released into.
