倒吊桶式疏水閥

INVERTED BUCKET TRAP

　　倒吊桶式疏水閥

　　倒吊桶式蒸汽疏水閥它是利用冷凝水和蒸汽密度差的工作原理，內部結構是由杠桿系統連接倒吊桶，克服 蒸汽壓力開關。內部是一個倒吊桶為液位敏感件，吊桶開口向下。裝置剛啟動時，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芯關閉閥門。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芯開啟閥門。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zui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；zui高背壓≥90%，所有內件都是不銹鋼制造，耐磨損、抗腐蝕；球形閥芯和閥座是線接觸，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*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，工作時無新鮮蒸汽泄漏，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 immediay. 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 interior of the inverted bucket steam trap is one of the most strong steam traps among mechanical steam trap, and its strength are shown as follows: can resist water hammer and drain non-condensing air continuously, with good anti-pollution performance; the maximum back pressure being ≥90%; all internal parts are made of stainless steel with anti-abrasion and anti-erosion capability; the spheric valve core and valve seat realize line contact, with excellent sealing performance and long service life; it can drain intermittently and continuously and can discharge the condensate water that is nearly at saturation temperature to offer optimal work efficiency to the heating equipment, its steam trap valve seat is protected by water sealing, so no fresh steam will leak out during the operating process to obtain good energy-saving effects.

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.

工作運轉流程圖     □空氣 ■蒸汽 ■凝結水

1、疏水閥關閉：

疏水閥初始充水后，蒸汽開始進入疏水閥并在倒吊桶頂部積聚，把倒吊桶浮起，將閥瓣推入閥座。

Steam trap closes

The steam trap is filled with water first, steam begins to enter the steam trap and accumulates at the top of the inverted bucket, and then lifts the bucket upward, the valve disc is pushed into the valve seat.

2、疏水閥開始打開：

冷凝水開始流入疏水閥，蒸汽和空氣被擠出倒吊桶，使桶漸失浮力，開始拉動閥瓣拉開閥座。

Steam trap starts to open

The condensate water starts to flow into the steam trap, steam and air are expelled from the inverted bucket, and the bucket will lose buoyancy gradually and begins to pull the valve disc to open the valve seat.

3、疏水閥排水：

當足夠的冷凝水進入疏水閥，蒸汽和空氣被擠出倒吊桶后，倒吊桶落下，將閥瓣拉離閥座，疏水閥向外推出冷凝水和空氣。

Steam trap discharge water

When adequate condensate water enters into the steam trap, steam and air are expelled from the inverted bucket, and the inverted bucket drops to pull the valve disc away from the valve seat, the steam trap drives the condensate water and air outward.

4、疏水閥關閉：

在冷凝水停止流入后，蒸汽進入疏水閥并浮起倒吊桶，迫使閥瓣插入閥座，循環重復。

Steam trap closes

When the condensate water stop flowing in, steam enters into the steam trap and drifts the inverted bucket up to force the valve disc to insert into valve seat. These procedures repeat.
