波纹管闸阀采用波纹管及填料双重密封结构,常用于有毒介质,易燃易爆介质,高温蒸汽,热油、氢气系统等系统中,特别适用于易燃、易爆、有毒及贵重介质的管路。波纹管密封闸阀的波纹管和阀盖和阀杆是焊接成一体的,无滑动密封结构,所以没有泄露点。阀杆上下移动时候,靠压缩波纹管而形变达到密封,不是靠相对滑动的滑动密封。密封性能远远优于普通铸钢闸阀用填料密封结构。产品广泛应用于石油、化工、制药、化肥、电力等行业。
1.波纹管密封闸阀,其关键部件金属波纹管,下端与阀杆组件采用自动滚焊焊接,上端与连接板自动滚焊接,在流体介质和大气之间形成一个金属屏障,确保阀杆零泄漏;
2.双重的密封设计(波纹管+填料)若波纹管失效,阀杆填料也会避免泄漏,并符合国际密封标准;
3.阀盖上自带有加脂接头,可直接对阀杆、螺母和轴套进行润滑,不像传统的只对螺纹加润滑油;
4.人体工程学设计手轮,使用寿命更长,操作轻松便捷,更安全可靠;
