杠杆浮球式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
双平衡杠杆浮球式疏水阀-3C产品信息
杠杆浮球式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,最小过冷度为 0℃。杠杆浮球式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露。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,阀蕊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。


Lever-ball float trap

Lever ball float type trap employs the buoyancy principle and the lever principles:to make the ball float ascend or descend by the change in the liquid level and then the ball float drives the lever to make the valve disc from or touch the valve seat to realize drainage and closed block vapor.The product adopts the automatic air  exhaust to automatically eliminate non-condensing air.It is very precise with high operating and long service life.It can discharge whenever there is any water,and its minimum subcooled temperature is 0℃.The lever-ball float trap adopts two kinds of structure modes:A:Single valve seat-lever ball float;B:double balanced valve seat-lever ball float.

Single valve seat:it needs to overcome the operation on the valve seat by the medium pressure;the hole caliber of the valve seatcannot be too large and is applicable to such low displacement condition as mini-equipment,steam tracing pipeline and steam mainpipe.The hole of the valve seat is designed beneath the water level of the condensate water to form water sealing to keep waterapart from vapor,so as to prevent the leakage of the vapor.Though there is no condensate water that uses ball-type sealed lever tomake the valve clack tightly adhesion to the valve seat,it can prevent the fresh vapor from leakage.Further,the product is free ofthe affect of the fluctuation of the condensate water's quantity and temperature.

The double balanced valve seat:this valve is designed to have two valve openings.The pressure of the medium act against the two valve seats equally in reverse direction,so the pressure on the valve seat is offset,the valve core assumes relatively low pressure when the valve is open,in this way the overlarge displacement is obtained.During the operating process,the ball float floats with the change in liquid level of the valve cavity to make the lever open or close the valve seat.The hole of the valve seat is designed beneath the water level of the condensate water to form water sealing to keep water apart from vapor,so as to prevent the leakage of the vapor.Further,the product is free of the affect caused by the fluctuation of pressure,temperature and condensate's flow.


优点:

1、采用新型阀机构(新 SCCV 关闭方式和Z型结构),具有优良的密封性和耐久性。
2、双平衡阀座设计,比一般的疏水阀体积小而排量大,在特大排量场合更能发挥性。
3、单阀座设计可以水平或垂直安装,可以满足高背压,低排量蒸汽管线。
4、内装空气自动排放阀,可防止空气气堵和蒸汽汽锁。
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。


Merits

1.To use new-style valve mechanism (new SCCV closing mode and Z-shaped structure) to boast excellent tightness and endurance.
2.To employ double balanced valve seat design,it has smaller volume and larger displacement and can exert its advantages when needing large displacement.
3.The single valve seat model can be installed horizontally and vertically,satisfying the requirements of steam pipeline with high backpressure and low displacement.

4.The built-in automatic air exhaust can prevent air blocking and steam locking;

5.As all components are installed on the valve cover,so they can be maintained and cleaned up simply and easily without being removed from pipe arrangement.
