倒吊桶式蒸汽疏水阀它是利用冷凝水和蒸汽的密度差的工作原理，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，倒吊桶开口向下。装置刚起动时，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心关闭阀门。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心开启阀门。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;最高背压≥90%，所有内件都是不锈钢制造，耐磨损、抗腐蚀;球形阀心和阀座是线接触，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，使加热设备达到理想工作效率。倒吊桶式蒸汽疏水阀的阀座处于水密封的保护下，工作时无活蒸汽泄漏，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 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、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.

　　主要特点

　　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、汽水分离可靠，阀内始终处于水封状态，有效阻止蒸汽泄露。

　　3、敞口型的浮子抗水击，设有排水孔，防止气锁或气堵现象。

　　4、用于蒸汽主管、分气缸、热交换器、硫化机、干燥机、空调机、医院用汽设备等。

　　Main Features

　　1.Have strong adaptive capacity to the occurrence quantity of condensation water,namely,the ability to both intermittent and continuous discharge.

　　2.Reliable separation of steam and water,the inner part of the valve is always in water seal state,which can effectively prevent the leakage of steam.

　　3.Open mouth-shaped float resists water attack,and is equipped with a vent so as to prevent vapor lock or gas block.

　　4.Mainly used in the steam main pipe,sub-cylinder,heat exchanger,vulcanizing machine,dryer,air-conditioning machine,hospital steam equipment,etc.
