进口杠杆浮球式蒸汽疏水阀，Lever ball float type steam trap是利用浮力原理和杠杆原理，通过液位的变化使浮球上升或下降，浮球驱动着杠杆使得阀瓣离开或接触阀座达到开启排水和关闭阻汽的作用。采用自动排空气阀，能自动排除不凝结气体，非常灵敏，工作质量高，使用寿命长。连续排水，有水即排，zui小过冷度为 0℃。进口杠杆浮球式蒸汽疏水阀采用两种结构方式 A：单阀座-杠杆浮球; B：双平衡阀座-杠杆浮球。
  单阀座：需要克服介质压力对阀座的作用，阀座的孔径不能很大，适用于小型设备、伴热管线，蒸汽主管等排水小的场合。阀座孔设计在凝结水水位以下，自然形成水封，水、汽自然分离，达到无蒸汽泄漏，即便没有凝结水采用球型密封的杠杆使得阀瓣紧贴阀座，达到无新鲜蒸汽的泄漏。不受凝结水量波动和温度的影响。
  双平衡阀座：该阀利用双阀孔设计，介质的压力对两个阀座作用相等，方向相反，介质压力对阀座作用相抵消，阀芯在开阀时压力相对减少，从而获得超大排量。工作时浮球随阀腔内液体位的变化而上下浮动，带动杠杆打开或关闭阀座。由于阀座孔在凝结水水位以下，形成水封，水、汽自然分离，达到无蒸汽泄漏。不受压力、温度、冷凝水流量波动的影响。
德国托克TOK品牌：用途：
杠杆浮球式蒸汽疏水阀，广泛用于工业蒸汽加热设备，各种大型热交换器及干燥机、夹套锅等，特别应用于冷凝水特大排量在的工作场合。

杠杆浮球式蒸汽疏水阀特点：
此超大排量型蒸汽疏水阀，在整个工作压力范围内无需调整和更换内件，即可充分排除大量的疑结水。排水过冷度可达0℃，特别适合用于疑结水量大的工作场合。
(A) the use of lever ball float steam trap:
Lever Ball Float Steam Traps are widely used for industrial steam heating equipment, heat exchangers and a variety of large dryers, folder jacketed kettle, etc., especially used in large displacement of water condensation in the workplace.
(B) Leverage Ball Float Steam Trap features:
This large displacement type steam trap, the entire operating pressure range without adjustment and replacement of parts, can be fully ruled out a large number of suspected knot water. Drainage undercooling up to 0 ℃, especially for a large amount of water used for suspected knot workplace.                                         
杠杆浮球式蒸汽疏水阀结构特点及工作原理： 
1、采用轧装阀机械(新SCCV开关方式)，具有优良的密封性和耐久性。
2、平衡双阀座设计，比一般的疏水阀体积小而排量大，特大排量场和更能发挥*性。
3、内装双金属片空气自动排放阀，可防止空气气堵和蒸汽汽锁。
4、采用*的U型双金属通气口，可大大缩短设备起动时间。
5、全部部件安装在阀盖上，阀无需从配管上卸下，就可维修保养，简单方便。
Lever Ball Float Steam Traps structural characteristics and working principle of:
1, using the mechanical rolling Valve (New SCCV switch mode), with excellent sealing and durability.
2, balanced two-seat design, trap size than the average small and large displacement, large displacement field and play more advantages.
3, built-in bimetal automatic air relief valve to prevent air and steam vapor lock gas block.
4, the unique U-shaped bi-metallic vent, can greatly reduce device startup time.
5, all the components installed in the valve cover, valve without removing from the piping on, you can repair and maintenance, easy and convenient.
