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

機(jī)械型疏水閥 Mechanical traps
機(jī)械型也稱浮子型，是利用凝結(jié)水與蒸汽的密度差，通過凝結(jié)水液位變化，使浮子升降帶動閥瓣開啟或關(guān)閉，達(dá)到阻汽排水目地。機(jī)械型疏水閥的過冷度小，不受工作壓力和溫度變化的影響。有水即排，加熱設(shè)備里不存水，能使加熱設(shè)備達(dá)到最佳換熱效率。最大背壓率為80%，工作質(zhì)量高，是生產(chǎn)工藝加熱設(shè)備最理想的疏水閥。
機(jī)械型疏水閥有自由浮球式、自由半浮球式、杠桿浮球式、倒吊式等-----

1、自由浮球式疏水閥

自由浮球式疏水閥的結(jié)構(gòu)簡單，內(nèi)部只有一個活動部件精細(xì)研磨的不銹鋼空心浮球，既是浮子又是啟閉件，無意損零件，使用壽命很長，“蘭高”牌疏水閥內(nèi)部帶有Y系列自動排空氣裝置，非常靈敏，能自動排空氣、工作質(zhì)量高。設(shè)備剛啟動工作時，管道內(nèi)的空氣經(jīng)過Y系列自動排空氣裝置排出，低溫凝結(jié)水進(jìn)入疏水閥內(nèi)，凝結(jié)水的液位上升，浮球上升，閥門開啟，凝結(jié)水迅速排出，蒸汽很快進(jìn)入設(shè)備，設(shè)備迅速升溫，Y系列自動排空氣裝置的感溫液體膨脹，自動排空氣裝置關(guān)閉。疏水閥開始正常工作，浮球隨凝結(jié)水液位升降，阻汽排水。自由浮球式疏水閥的閥座總處于液位以下，形成水封，無蒸汽泄漏，節(jié)能效果好。最小工作壓力0.01MPa，從0.01MPa至最高使用壓力范圍之內(nèi)不受溫度和工作壓力波動的影響，連續(xù)排水。能排飽和溫度凝結(jié)水，最小過冷度為0℃，加熱設(shè)備里不存水，能使加熱設(shè)備達(dá)到最佳換熱效率。背壓率大于85%，是生產(chǎn)工藝加熱設(shè)備最理想的疏水閥之一。

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.
