  给大家讲一讲焊接截止阀的结构特点

  焊接截止阀具有非常可靠的切断作用

  一旦焊接截止阀的阀瓣处于开启状态,它的阀座和阀瓣的密封面之间就没有接触,具有非常可靠的切断作用,这种阀门非常适用于切断或调节介质和节流,焊接截止阀结构简单,制造和维修方便,工作行程小,开闭时间短,密封性能好,密封面间摩擦小,使用寿命长等。

  焊接截止阀的阀瓣为圆锥形,阀杆设有倒置式密封,密封性好,阀杆表面氮化,具有良好的耐腐蚀性和抗摩擦性,柔性石墨填料,密封可靠,操作灵活,启闭扭矩小。

  焊接截止阀的结构特点

  1.焊接截止阀可以无摩擦地打开和关闭,该系统的功能可以完全解决传统阀门的密封受密封面之间相互贸易摩擦影响的问题。

  2.安装结构,安装在管道上的阀门可直接在线检查和维修,可有效减少装置的停机,降低成本。

  3.单座设计,本实用新型解决了阀腔介质压力异常升高影响使用安全的问题。

  4.低扭矩设计,阀杆的特殊结构设计使得用小手就能轻松开启和关闭阀门。

  5.楔形密封系统的结构,阀门由阀杆提供的机械力密封,将球楔压在阀座上,使阀门的密封性能不受其他管道压差变化的影响,各种工况下密封材料的性能有了可靠有效的保证。

  6.密封面的自清洁结构,当球倾斜远离阀座时,它会沿流体密封面360通过均匀接地线,既排除了阀座局部侵蚀的高速流体,又冲走了积聚的密封面,从而达到自洁的目的。

  7.阀门系统直径DN50以下的阀体和阀盖为模锻件,DN65以上的阀体和阀盖为铸钢件。

  8.阀体与阀盖的连接形式有多种,如夹销连接、法兰垫片连接和自密封螺纹连接。

  9.阀座和阀瓣的密封面由钴-铬-钨硬质材料合金通过不同的等离子喷焊或堆焊制成,密封面设计成高硬度、耐磨、耐刮擦、使用寿命长。

  10.杆的材质为氮化钢,氮化硬度高,表面干燥,耐磨、耐刮、耐腐蚀,使用寿命长。
