真空阀门设计时的注意事项及结构计算方法

滚球体育app SHIJIAN:2017-4-26 14:52:08 LAIYUAN:WENZHOUNIWEIFAMEN LIULANSHU:7256

   真空阀门是真空系统的重要元件。对于构成管路一部分的阀门,其流导大小是一个重要的性能参数。对于主要用来起开关气路作用的阀门,阀板关闭的密封性能也是重要的性能参数之一。密封性能是用其漏气率来衡量的。对于主要用来调节气流大小的阀门,能够调节气流量的精度及范围,则是一项重要的性能参数。对于全金属超高真空阀门滚球体育app,每次关闭是否性能稳定?使用寿命是否长?是其主要的性能指标。

  如图6所示,阀板上的斜面沿着垫块上的斜面向左滑动、阀板与垫块被撑开而将胶圈压紧密封。和螺旋压紧类似,若斜面升角小于两者材料的摩擦角,压紧后就能实现自锁。然而对于普通钢材,摩擦角为5°43’,若要保证自锁,需斜面升角入<5°43'。假设胶圈压下量为1.5mm,则在极限情况下,上述阀板需相对于斜块向左移动15mm才行。即阀板接触到胶圈后,还要相对于胶圈横向移动15mm,显然这是不能允许的。所以这种结构要利用传动连板5转至死点来保证自锁。
