自由浮球式蒸汽疏水阀 Free ball float tupe steam trap
机械型疏水阀 Mechanical traps
Mechanical trap is also called float trap,based on the density differences between condensed water and steam as well as the change of the liquid level of the condensed water,blocks the steam and realizes water discharge through the open or close of the valve flap driven by the lifting of the float.The mechanical trap boasts small sub-cooled temperature,uncontrolled by the working pressure and temperature changes.This type of traps can discharge the water as soon as it produced.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 80%.With high quality,it is best trap for your heating equipmens.
Mechanical traps include free-ball float traps,halfball float trap,level ball float trap and inverted bucket trap.
1.Free-ball float traps
Free-ball float traps have simple structures,with only one hollow float ball of stainless steel inside,which is both float and switch.With no vulnerable parts,it enjoys long-term service life.The traps of‘langao’have automatic air discharging fixture inside，which is sensitive and is able to discharge air automatically.When the trap starts,the air in the pipelines is discharged through automatic air discharging fixture of swties Y.Then the condensed water of low temperature flows into the 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 remperature 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 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 valve always stays below the liquid level,forming water seal,which realizes no steam leakage and excellent energy saving performance.The smallest working pressure of the trap is 0.01MPa,from which to the largest working pressure,the trap can discharge the water in continuous way,uncontrolled by the changes of temperature and pressures.This kind of trap can also discharge condensed water of saturation temperature,with smallest subcooled temperature being 0℃.There’sno 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%.With high quality,it is best trap for your heating quipments.
