Free Float Steam Trap working principle

Free Float Steam Trap has simple structure, only with one stainless steel hollow float ball inside.The Free Float Ball acted as both float and switch. With no vulnerable parts, it enjoys long-term service life.

Our Goole Free Float Steam Trap has automatic air vent inside, which is sensitive and is able to discharge air automatically. When the free float steam trap starts working, the air in the pipelines is discharged through automatic air vent. Then the condensed water of low temperature flows into the steam trap, with the liquid level and float ball rising, the valve open. And then the condensed water is discharged rapidly, with the steam vaporizing into the equipment, whose temperature accordingly rises. At that time, the temperature-sensing liquid in the automatic air discharging equipment expands and the equipment stops working. When being into operation, the float of the steam trap rises and falls with the liquid level of condensed water, the steam in this way is blocked and the water is discharged. The base of the free ball float steam trap always stays below the liquid leve, forming water seal, which realizes no steam leakage and excellent energy saving performance. 

The smallest working pressure of the free float steam trap is 0.01 MPa, from which to the largest working pressure, the steam trap can discharge the water in continuous way, uncontrolled by the changes of temperature and pressure.

This Free float steam trap can also discharge condensed water of saturation temperature, with smallest subcooled temperature being 0 Deg C. There's no water stored in the heating equipment, which can make the heating equipment achieve optimal efficiency of heat exchanges. Its largest rate of back pressure reaches 80%. Free Float Steam Trap is an ideal steam trap for heating equipment.
