进口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。倒吊桶式疏水阀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。
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。
