Z41H国标闸阀说明:Z41H国标闸阀,法兰闸阀,重型闸阀适用于公称压力PN1.6~16.0MPa,工作温度≤-29℃~550℃的石油、化工、水力、火力电站各种系统的管路上,切断或接通管路介质。适用介质为:水、油品、蒸气、及酸、碱、氨、尿素、含硫天然气等。操作方式有:手动、齿轮传动、电动、气动等。
Z41H国标闸阀结构特点
1、选材考究,符合国内外相关标准,材料的全面质量高。
2、符合标准的要求,密封可靠、性能优良、造型美观。
3、密封副配对合理,闸板和阀座的密封面采用不同硬度的司太立(Stellite)钴基硬质合金堆焊而成,密封可靠、硬度高、耐磨、耐高温、耐腐蚀、抗擦伤性能好、寿命长。
4、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。
5、采用楔式弹性闸板结构,中大口径设置推力轴承,磨擦力小,并配有撞击手轮,启闭轻松自如。
6、可采用各种配管法兰标准及法兰密封面形式,满足各种工程需要及用户要求。
