(蒸汽疏水器)进口杆杠浮球式疏水阀特点∶ Performance characteristics

内置自动排空气装置，启动迅速，无空气气堵，排除不可凝结气体性能好 RETZ Built in automatic air exhaust device, quick start, no air blockage, good performance in eliminating non condensable gas

该阀能迅速自动地连续排放饱和凝结水，保证加热设备内不会有水积聚，从而获得最高加热效率 The valve can rapidly and automatically discharge the saturated condensate continuously to ensure that there is no water accumulation in the heating equipment, so as to obtain the highest heating efficiency

排水阀座孔始终在凝结水水位以下，形成水封，工作时无新鲜蒸汽泄漏  The valve can rapidly and automatically discharge the saturated condensate continuously to ensure that there is no water accumulation in the heating equipment, so as to obtain the highest heating efficiency

单阀座杠杆浮球式蒸汽疏水阀球面密封无集中磨损，关闭阀座孔时，具有软着陆特点，提高寿命 The spherical seal of the single seat lever floating ball steam trap has no centralized wear. When the valve seat hole is closed, it has the characteristics of soft landing and improves the service life

背压率大于90%，便于凝结水回收  The back pressure rate is greater than 90%, which is convenient for condensate recovery

密封性能好，漏气率低，节能效果好 Good sealing performance, low air leakage rate and remarkable energy saving effect

安装灵活，即可立式安装，也可水平安装 Flexible installation, either vertical or horizontal
