Q41H, Q41Y metal seal valve
Product Name:
Q41H, Q41Y metal seal valve
Description:

金属硬密封法兰球阀 Q41H、Q41Y

金属硬密封球阀的特点
采用先进的球体和阀座硬化技术

金属硬密封球阀的球体与阀座完全采用金属对金属的密封方式,为了确保阀门在各种温度和压力下的可靠密封,针对用户的不同使用工况和要求,可以采用多种先进的球体和阀座的硬化技术,包括超音速喷涂、镍基喷焊、表面特殊硬化、硬质合金喷焊以及采用高强度高硬度陶瓷材料等,球体和阀座表面硬度一般可达到HRC60以上,最高可达HRC74以上。密封面材料耐温可达540℃,最高可达980℃。材料的结合强度可以达到10000PSI以上,密封面材料还具有很好的耐磨擦、耐冲击等性能。金属硬密封球阀能够适用于绝大多数的苛刻工况条件。

防止阀门在高温下的涨死

高温工况下由于热膨胀而容易引起球体与阀座的涨死,从而导致阀门无法开启。金属硬密封球阀采用了碟簧或弹簧加载的密封结构,在高温下零部件的热膨胀可以被碟簧或弹簧所吸收,故能够保证阀门在高温下不会被涨死,并能够在高温下灵活启闭。

优异的密封性能

采用独特的球体研磨工艺,通过球体与研磨器具在空间不同方位的旋转,使球体表面达到极高的圆度和光洁度,阀门的密封性能完全达到或超过标准要求。
