Thermodynamic steam trap

The thermodynamic steam traps have (English thermodynamic steam trap) as a function part comprises a valve disc which is flowing in a closed space from below.

If condensate flows through the central inlet hole, it lifts the valve disc and flows off via the annular channel and the drain hole. If all the condensate has flowed out and steam comes in, it also lifts the valve disc and, due to its low viscosity, flows out much faster. Part of the steam reaches the back of the valve disc, is slowed down there and thereby increases its static pressure. He pushes the valve disk down and closes the outlet opening so that no more steam can escape. In a short time, the steam cools down between the valve disk and the housing cap and condenses. This causes the pressure on the back of the valve disk to drop, so that inflowing condensate or incoming steam lifts the valve disk again. A new outflow or closing process begins. Thermodynamic steam traps work in the rhythm of discharge and closing cycles.
