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.
优点：
1、对凝结水的发生量适应性强，既可间歇排放，又可连续排放。
2、内部装有大排量的双阀座差压机和SCCV关闭系统，体积小而排量大。
3、内部零件全部采用不锈钢制造，并且安装在阀盖上维修保养极为方便。
4、背压率高（90%）。
5、汽水分离可靠（水汽经U型通道从阀下部进入），阀内始终处于水封状态，有效阻止蒸汽泄露。
6、敞口型的浮子抗水击，吊桶上设有排水孔，可有效防止蒸汽气锁、空气气堵现象（非凝结性的高温空气也排除）。7、与杠杆机构结合制造高压阀。
Merits
1.Strong adaptability to happening of condensate water,capable of intermittent or continuous discharge.
2.Equipped with double-valve pressure differentiator and SCCV shutdown system,with small size but large discharge capacity.
3.All inner parts made of stainless steel and mounted on valve covers,easy to maintain and repair.
4.High backpressure rate of 90%.
5.Reliable separation of vapor and water (vapor enters from the lower part of the valve through the U-shape passage),the inner part of the valve is in water seal state,which effectively prevents the leakage of steam.
6.Water-resistant open floater with gas vent through the bucket's vent,effective to prevent steam locking or air blocking(except the non-confensed high-temperature air).
7.Suitable to be joined with lever mechanism for producing high-pressure valve.
