進口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(tǒng)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，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(huán)工作，間斷排水。
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(yōu)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(jié)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(xù)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。
