Thermodynamic steam trap

These traps have an inherently rugged design and are commonly used as drip traps on steam mains and supply lines. Thermodynamic disc steam traps have an intermittent, cyclical operating characteristic. Operating Mechanism of Thermodynamic Disc Traps.

This video explains how a Thermodynamic Steam Trap works. One reason for that problem is the generation and accumulation of steam condensate in the steam lines. During the initial startup cold air and Condensate lift the disc from the seat to pass radially outwards through the annular groove to the exit port (refer Figure- Sketch 1). Thermodynamic traps have only one moving part, the valve disc, which allows condensate to be discharged when present and closes tightly upon the arrival of steam.

Disc-type traps and impulse-type traps are both examples of steam traps belonging to this classification. Thermodynamic Steam Traps Steam Traps Spirax Sarco USA Thermodynamic steam traps combine reliability, simplicity and efficiency of operation. Popular traps in these categories includes the float steam trap, the thermostatic steam trap, the inverted bucket steam trap and the thermodynamic disc steam trap.

TLVs thermodynamic steam traps are all disc-type traps, which allow less steam leakage and have fewer problems with scale and build-up of dirt. Able to withstand superheat, waterhammer, corrosive condensate, freezing and vibration. The traps in the DK series are correspondingly simple in structure, feature a small, compact body and are low in cost.

The valve mechanism comprised of a disc and seat rings opens to discharge condensate for a few seconds and then closes for a generally longer period until a new discharge cycle begins. A steam trap prime missions is to remove condensate and air preventing escape of live steam from the distribution system. To close the disc inside thermodynamic steam trap, low pressure is required below the disc which is possible only if velocity of flow below the disc is high. Incoming condensate lifts the valve disk of the regulator to the open position, while steam causes it to close immediately.

These steam traps work on the basis of a simple thermodynamic principle. So thermodynamic steam traps will not work properly on very low differential pressures. Thermodynamic Trap: Kinetic Energy Operated Steam Trap Working principle of thermodynamic trap: The functioning of the thermodynamic trap can be understood from the accompanying sketch above. Almost all mariners are familiar with the problem of steam hammering that occurs in steam lines.

Which one is preferred depends on the application. With just one moving part - a hardened stainless steel disc - they give a blast discharge with clean, tight shut-off. And thats the principle behind condensation drying. Bergen Plumbing Heating Cooling - Rated based on Reviews I wanted to give a heads up that I used Bergen plumbing based on the references I.
