    倒吊桶式蒸汽疏水閥它是利用冷凝水和蒸汽的密度差的工作原理，內部結構是由杠桿系統連接倒吊桶，克服蒸汽壓力開關倒吊桶式疏水閥內部是一個倒吊桶為液位敏感件，倒吊桶開口向下。裝置剛起動時，管道內出現空氣和低溫冷凝水，此時疏水閥是全開放，空氣和低溫冷凝水迅速排出，裝置很快提升溫度。當蒸汽進入倒吊桶內，倒吊桶產生向上浮力，倒吊桶連接杠桿帶動閥心關閉閥門。倒吊桶上開有一小孔，能自動排空氣，當一部份蒸汽從小孔排出，另一部份蒸汽產生凝結水，倒吊桶失去浮力向下沉，倒吊桶連接杠桿帶動閥心開啟閥門。當蒸汽再進入倒吊桶內，閥門再關閉，循
環工作，間斷排水
    倒吊桶式蒸汽疏水閥是機械型蒸汽疏水閥中堅固的疏水閥之一，它的優點是：不怕水擊，能連續排不冷凝氣體，抗污性能好；最高背壓≥90%，所有內件都是不銹鋼制造，耐磨損、抗腐蝕；球形閥心和閥座是線接觸，密封性能好，使用壽命長；間斷排水和連續排水，能排接近飽和溫度冷凝水，使加熱設備達到理想工作效率。倒吊桶式蒸汽疏水閥的閥座處于水密封的保護下，工作時無活蒸汽泄漏，節能效果好。
    它適用于石油、化工、印刷、造紙、制藥等工業蒸汽加熱設備和蒸汽管網的阻汽排水。

Inverted Bucket Trap 

    The interior of the inverted bucket steam trap:this valve adopts the operating principles of density difference between condensate water and steam,and the leverage system connects with inverted bucket to form its internal structure,thus controlling the open and close of the steam pressure.The interior of the inverted bucket steam trap is an inverted bucket,a liquid level sensitive part,with the bucket's opening downward.When the device just started,air and low temperature condensate water occur in the pipes,at the moment the steam trap opens thoroughly,the air and low-temperature condensate water are discharged rapidly and the temperature of the device rises immediately.When any steam enters into the inverted bucket,the bucket will obtain buoyancy and the fixed lever of the bucket drives the valve core to close the valve.There is small aperture on the inverted bucket,which can discharge air automatically.As some of steam is discharged from such aperture,while other steam produces condensate water.The inverted bucket loses the buoyancy and sinks down and its fixed lever drives the valve core to open the valve.When the steam re-enters into the bucket,the valve will close again.It repeats the said procedures to discharge water intermittently.
    The inverted bucket steam trap is one of the most solid mechanical steam traps. It has the following advantages: it is not afraid of water hammer, can continuously discharge non condensing gas, and has good anti pollution performance; the maximum back pressure is ≥ 90%, all internal parts are made of stainless steel, wear-resistant and anti-corrosion; the ball valve core and valve seat are in line contact, with good sealing performance and long service life; intermittent drainage and continuous drainage It can discharge condensate close to saturation temperature and make heating equipment reach ideal working efficiency. The valve seat of inverted bucket steam trap is under the protection of water seal, and there is no live steam leakage during operation, so the effect of energy saving is good.
    The product applies to such industrial steam heating equipment as petroleum,chemical,printing,paper making and pharmaceuticals and discharge of the steam pipe network.

優點：

1、內腔所有運動部件均為不銹鋼，耐磨損，耐腐蝕。
2、由于蒸汽不能到達被水封的閥座孔，所以無蒸汽損失，高效節能。
3、浮桶倒置，不會被破壞壓扁，不怕水擊，壽命長。
4、倒置桶頂部設有排氣孔。連續排空氣性能好，不會形成冷滯后和氣堵。
5、不受背壓的影響，在高的背壓下能很好地工作。 
6、工作可靠，只有兩個運動部件 ( 自由杠桿結構和倒置桶 ) ，故不會產生卡阻。

7、閥座與閥瓣在閥的頂部，閥瓣在開關中可以使污物通過，有良好的自我清洗性能 ，無污物困擾。

Merits

1.All moving parts of the internal cavity are made of stainless steel,capable of resistance to abrasion and erosion.
2.As the steam cannot reach the sealed aperture of the valve seat by water,the steam will not lose but has high efficiency and save energy.
3.The float bucket is located inversely.It can resist to water's strike and has long service lift.
4.The invented bucket has gas vent and performance of discharging the air continuously is excellent,without forming cool hysteresis and air blocking.
5.It is free of the affect of the back pressure and can perform well under high back pressure.
6.It has reliable operation and only two moving parts—free lever structure and inverted bucket,so no blockage is produced.

7.The valve seat and valve disc are located at the top of the valve.The valve disc allows the pollutants to pass,so it attains good self-cleaning performance,without affected by pollutants.

主要特點

1、對凝結水的發生量適應性強，既可間歇排放，又可連續排放。

2、汽水分離可靠，閥內始終處于水封狀態，有效阻止蒸汽泄露。

3、敞口型的浮子抗水擊，設有排水孔，防止氣鎖或氣堵現象。

4、用于蒸汽主管、分氣缸、熱交換器、硫化機、干燥機、空調機、醫院用汽設備等。

Main Features

1.Have strong adaptive capacity to the occurrence quantity of condensation water,namely,the ability to both intermittent and continuous discharge.

2.Reliable separation of steam and water,the inner part of the valve is always in water seal state,which can effectively prevent the leakage of steam.

3.Open mouth-shaped float resists water attack,and is equipped with a vent so as to prevent vapor lock or gas block.

4.Mainly used in the steam main pipe,sub-cylinder,heat exchanger,vulcanizing machine,dryer,air-conditioning machine,hospital steam equipment,etc.
