Overview

The biggest advantage of the super large flow lever floating ball steam trap is that it is not affected by fluctuations in pressure, temperature, and condensate flow rate. It can continuously drain water and discharge as soon as there is water. The minimum subcooling degree is 0 ℃, which can achieve the best working efficiency of the heating equipment; The valve seat of the lever floating ball steam trap is always below the liquid level, forming a water seal and no steam leakage; Its minimum working pressure is 0.01Mpa, and the maximum back pressure rate is ≤ 85%; Internally equipped with an exhaust system, the most advanced Y-series membrane box components are used as automatic exhaust valves, which can automatically remove non condensable gases, are very sensitive, have high working quality, and have a long service life. This steam trap is designed with a balanced double seat structure, which can achieve small volume and large drainage capacity. It is particularly suitable for blocking steam drainage in large heating equipment and heat exchange station equipment, and is the preferred steam trap for large heating equipment.

特点

1.连续排水，有水即排，不受工况波动影响：依靠凝结水液位变化驱动浮球联动杠杆启闭阀口，以液位为唯一判定基准。凝结水进入阀体即连续排出，无间歇，排量随凝结水产生量自动调节。区别于波纹管式依靠温度感应的间歇排水方式，本阀为连续排水，可实现接近饱和温度的大排量连续排放，确保加热设备始终无积水，换热效率最大化。

2.平衡双阀座结构，小体积实现特大排量：采用平衡双阀座设计，流体作用于上下阀瓣的介质力相互抵消，大大减小阀芯启闭所需驱动力。在同等浮球浮力条件下，可提供远超常规结构的流通能力，实现小体积、大排量，特别适用于大型加热设备和换热站设备的大凝结水负荷工况。

3.阀座常浸水封，零蒸汽泄漏：阀座总处于液位以下，排水口始终被凝结水淹没形成完整水封，蒸汽无通道泄漏。区别于波纹管式依靠低温水封与阀门关闭双重阻汽，本阀依靠连续水封自然阻汽，泄漏率极低，无可见蒸汽逸出，节能效果显著。

4.最低工作压力0.01MPa，背压适应性强：超低启闭压差设计，最低工作压力可达0.01MPa，适用于低压蒸汽系统。最大背压率≤85%，在变负荷、变背压工况下仍能稳定排水，适配各类复杂蒸汽管网。

5.内置Y系列膜盒自动排气，无气堵风险：内部配备最先进的Y系列不锈钢膜盒式自动排空气阀，可灵敏、可靠地自动排出不凝结气体（空气、CO₂等），避免气堵导致排水失效。区别于波纹管式依靠定期手动排气或顶部排气阀排气的维护方式，本阀全自动排气，无需人工干预。

6.结构成熟，使用寿命长：杠杆浮球机构设计成熟可靠，浮球与杠杆均采用不锈钢材质，耐腐蚀、耐冲蚀。无薄壁感温元件、无热静力膜片，不存在波纹管疲劳断裂或感温介质泄漏等失效模式，长期运行故障率低，使用寿命远超热静力类疏水阀。

7.抗水击能力较强，适用大流量高压差场合：全不锈钢浮球与杠杆机构结构强度高，可耐受一般蒸汽水击冲击，适应大流量、高背压、负荷波动剧烈的换热工况。区别于波纹管式适用于小排量稳定工况，本阀专为大排量变负荷工况设计，排量范围广。

8.选型灵活，适配性强：标配法兰连接，可选配承插焊连接，适配不同管路要求。可根据凝结水负荷选配不同口径（DN15～DN200+），覆盖从中小型设备到大型换热站的全场景需求，安装方式以水平安装为准，确保浮球动作灵敏可靠。
