CS11H内螺纹自由浮球式蒸汽疏水阀利用凝结水与蒸汽的密度差,通过凝结水液位变化,使空心浮球表面贴合阀座来开启或关闭阀门,达到阻气排水的目的。该阀利用浮力原理,浮球根据凝结水量的多少随水位的变化而作升降,自动调节阀座孔的开度,连续排放凝结水。当凝结水停止进入时,浮球靠自重降到底部,关闭排水阀座。由于排水阀座孔在凝结水水位以下,水汽自然分离,形成水封,达到无蒸汽泄漏。
Structural Characteristics
- Highly precision ground stainless steel float, improved pressure strength and sealing performance, corrosion resistance.
- The parts of the action are floating balls, which work reliably and have a long service life.
- The ability to continuously discharge saturated condensate heating equipment without water buildup, resulting in high heat transfer efficiency.
- Steam pressure changes are not affected, the float can automatically adjust the opening of the drain valve seat hole, continuous operation and stable performance.
- External manual air venting device, pneumatic quickly.
- The no-load air leakage rate is less than 0.51 TP3T.
- Maximum operating back pressure 80%.
- Subcooling <5°C.
