进口加长杆波纹管截止阀是带加长阀杆的波纹管截止阀,阀杆科加长0.5-1.5M,其关键部件——金属波纹管,被密封在加长的密封空间里面,不受介质、压力和温度的影响,因此比普通的波纹管截止阀使用寿命更长。The lengthened bellows globe valve is lengthened stem with a corrugated pipe cut-off valve, valve stem, long 0.5-1.5M, its key component -- metal corrugated pipe, sealed in the elongated sealed space inside, is not affected by the medium, pressure and temperature, so than the ordinary life of bellows globe valve longer
该波纹管截止阀的密封元件——钛金,是一种耐高温、耐腐蚀的材料,加在密封处形成重密封,比传统的波纹管截止阀又多了一道密封,形成三重重密封,性能更加安全可靠、耐用。
产品特征
-撞击手轮降低驱动力矩,并可以使阀门密封得到有效保证
-推力轴承降低启闭力矩,可以减少阀杆螺母与支架的磨损
-定位块设置防止阀杆与波纹管相对转达而引起波纹管失效
-必要的波纹管波数与层数能有效地保证阀门使用寿命
-扩大过流部位能保证阀门的流通能力,并防止密封面过流位置介质流速过快,有效抑制冲蚀、空化和闪蒸
