自由浮球式蒸汽疏水阀 Free ball float tupe steam trap

机械型疏水阀 Mechanical traps
机械型也称浮子型，是利用凝结水与蒸汽的密度差，通过凝结水液位变化，使浮子升降带动阀瓣开启或关闭，达到阻汽排水目地。机械型疏水阀的过冷度小，不受工作压力和温度变化的影响。有水即排，加热设备里不存水，能使加热设备达到**换热效率**大背压率为80%，工作质量高，是生产工艺加热设备**的疏水阀。
机械型疏水阀有自由浮球式、自由半浮球式、杠杆浮球式、倒吊式等-----

1、自由浮球式疏水阀

自由浮球式疏水阀的结构简单，内部只有一个活动部件精细研磨的不锈钢空心浮球，既是浮子又是启闭件，无意损零件，使用寿命很长，“兰高”牌疏水阀内部带有Y系列自动排空气装置，非常灵敏，能自动排空气、工作质量高。设备刚启动工作时，管道内的空气经过Y系列自动排空气装置排出，低温凝结水进入疏水阀内，凝结水的液位上升，浮球上升，阀门开启，凝结水迅速排出，蒸汽很快进入设备，设备迅速升温，Y系列自动排空气装置的感温液体膨胀，自动排空气装置关闭。疏水阀开始正常工作，浮球随凝结水液位升降，阻汽排水。自由浮球式疏水阀的阀座总处于液位以下，形成水封，无蒸汽泄漏，节能效果好**小工作压力0.01MPa，从0.01MPa至**高使用压力范围之内不受温度和工作压力波动的影响，连续排水。能排饱和温度凝结水**小过冷度为0℃，加热设备里不存水，能使加热设备达到**换热效率。背压率大于85%，是生产工艺加热设备**的疏水阀之一。

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.
