Q41H US standard metal hard seal ball valve
产品工作原理及用途： 金属硬密封球阀是我公司开发的高性能阀门。阀座采用弹簧加载金属密封结构，可在高温下轻松启闭。球体和阀座经过特殊硬化处理，密封面不被碰伤。球阀具有双向密封功能。中小口径采用浮球结构（DN15～200mm），大中口径采用固定球结构（DN125～500mm）。 产品结构特点： 1、金属硬密封高温球阀采用偏心结构，在关闭过程中，阀座与球体之间的比压能迅速增大，从而保证了密封副的可靠密封。当阀门打开时，阀座迅速与球体脱离，有效地减小了操作扭矩，减少了阀座表面与球体之间损坏的可能性。 2、金属硬密封浮动球阀采用弹性加载结构，正常关闭时保证球体密封面与阀座密封的接触，在高温条件下，能有效补偿内部热膨胀，避免因高温造成的阻力，适合中小口径高温应用。 3、金属硬密封高温固定球阀除了具有金属硬密封偏心球阀的偏心特点外，其他优点也都在这里，此外，它可以双向使用，并且腔内不易沉积污垢，根据用户的工况条件，还可以在腔体内设置排污口。 4、金属硬密封高温球阀球体表面经过特殊硬化处理，阀座整体采用特殊硬质材料或局部堆焊硬质材料，保证密封副之间有合适的硬度差。 5、由于球体表面经过特殊表面硬化处理，阀座堆焊硬质合金，因此在阀门启闭过程中能很好地被介质冲刷，特别适用于含有固体颗粒和磨蚀性的介质。 6、除球体表面和阀座表面经过特殊表面处理外，其他密封材料均采用柔性石墨和金属缠绕垫片，因此可以在高温、高压条件下使用，并具有防火功能。 产品性能参数： 公称压力（PN） 1.6 2.5 4.0 6.4 壳体试验压力 2.4 3.8 6.0 9.6 密封测试 1.8 25.8 4.4
