产品说明

NK44H、NK64H真空闸阀连接形式分法兰、焊接两种,驱动方式有手动、电动两种。该阀门适用于工作温度≤425℃和≤550℃,工作介质为水、蒸汽或空气的管路上,作为启闭装置;尤其适用于火电厂汽机冷凝和真空负压系统,起真空隔离密封作用。

结构特点

1、设计了真空密封结构填料室,使系统与大气隔离,具有良好的环保性能。
2、选材考究,符全国内外相关标准,材料的质量高。
3、密封副配对合理,提高了密封性能,使用寿命长。
4、启闭件采用平行闸板双向弹性密封,摩擦力小,启闭轻松,维修方便,密封可靠,性能优良。
5、阀杆经调质及表面氮化处理,有良好的抗腐蚀性、抗擦伤性和耐磨性。
6、法兰垫片采用复合材料,膨胀系数大、气密性能好、保证系统与大气隔离可靠。
