倒吊桶式疏水阀

INVERTED BUCKET TRAP

 

　　倒吊桶式疏水阀

　　倒吊桶式蒸汽疏水阀它是利用冷凝水和蒸汽密度差的工作原理，内部结构是由杠杆系统连接倒吊桶，克服 蒸汽压力开关。内部是一个倒吊桶为液位敏感件，吊桶开口向下。装置刚启动时，管道内出现空气和低温冷凝水，此时疏水阀是全开放，空气和低温 冷凝水迅速排出，装置很快提升温度。当蒸汽进入倒吊桶内，倒吊桶产生向上浮力，倒吊桶连接杠杆带动阀芯关闭阀门。倒吊桶上开有一小孔，能自动排空气，当一 部份蒸汽从小孔排出，另一部份蒸汽产生凝结水，倒吊桶失去浮力向下沉，倒吊桶连接杠杆带动阀芯开启阀门。当蒸汽再进入倒吊桶内，阀门再关闭，循环工作，间 断排水。

　　倒吊桶式蒸汽疏水阀是机械型蒸汽疏水阀中zui坚固的疏水阀之一，它的优点是：不怕水击，能连续排不冷 凝气体，抗污性能好；zui高背压≥90%，所有内件都是不锈钢制造，耐磨损、抗腐蚀；球形阀芯和阀座是线接触，密封性能好，使用寿命长；间断排水和连续排 水，能排接近饱和温度冷凝水，使加热设备达到zui佳工作效率。倒吊桶式蒸汽疏水阀的阀座处于水密封的保护下，工作时无新鲜蒸汽泄漏，节能效果好。

　　它适用于石油、化工、印刷、造纸、制药等工业蒸汽加热设备和蒸汽管网的阻汽排水。

 

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.

 

优点：

1、内腔所有运动部件均为不锈钢，耐磨损，耐腐蚀。

2、由于蒸汽不能到达被水封的阀座孔，所以无蒸汽损失，高效节能。

3、浮桶倒置，不会被破坏压扁，不怕水击，寿命长。

4、倒置桶顶部设有排气孔，连续排空气性能好，不会形成冷滞后和气堵。

5、不受背压的影响，在高的背压下能很好地工作。

6、工作可靠，只有两个运动部件 （自由杠杆结构和倒置桶 ） ，故不会产生卡阻。

7、阀座与阀瓣在阀的顶部，阀瓣在开关中可以使污物通过，有良好的自我清洗性能 ，无污物困扰。

 

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.

工作运转流程图     □空气 ■蒸汽 ■凝结水

 

1、疏水阀关闭：

疏水阀初始充水后，蒸汽开始进入疏水阀并在倒吊桶顶部积聚，把倒吊桶浮起，将阀瓣推入阀座。

 

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、疏水阀开始打开：

冷凝水开始流入疏水阀，蒸汽和空气被挤出倒吊桶，使桶渐失浮力，开始拉动阀瓣拉开阀座。

 

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、疏水阀排水：

当足够的冷凝水进入疏水阀，蒸汽和空气被挤出倒吊桶后，倒吊桶落下，将阀瓣拉离阀座，疏水阀向外推出冷凝水和空气。

 

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、疏水阀关闭：

在冷凝水停止流入后，蒸汽进入疏水阀并浮起倒吊桶，迫使阀瓣插入阀座，循环重复。

 

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.
