Thermodynamic steam traps have a unique operating principle which relies on the dynamics of water and flash steam. They are simple, robust and reliable and can operate up to very high temperatures and pressures.
We would like to share with you an insight into our steam traps and what we have to offer from the TLV steam trap range.
How our steam traps work
The bimetal air vent ring is contracted, lifting the disc of the valve seat and allowing rapid discharge of air and cold condensate.
As temperature rises in the trap, the bimetal expands and releases the disc. The disc is then forced downwards by the low-pressure area created by the rapid flow of flashing condensate/steam below the disc, and the simultaneous high pressure in the pressure chamber above it. An air jacket insulates the cap's pressure chamber from the radiant heat loss that could cause no-load actuation.
Eventually, as condensate enters the trap and the steam pressure in the pressure chamber lowers, the inlet pressure pushes the disc up and enables the discharge of condensate. Entering flashing condensate/steam then closes the trap, as in step 2.
Advantages of the Thermodynamic Steam Trap
Thermodynamic traps can operate across their entire working range without any adjustment or change of internals.
They are compact, simple, lightweight and have a large condensate capacity for their size.
Thermodynamic traps can be used on high pressure and superheated steam and are not affected by waterhammer or vibration. The all stainless steel construction offers a high degree of resistance to corrosive condensate.
As the disc is the only moving part, maintenance can easily be carried out without removing the trap from the line.
The audible 'click' which occurs as the trap opens and closes makes trap testing very straight forward.
