高温安全阀

  2.4先导式(脉冲式)。利用导阀与主阀连在一起,通过导阀的脉冲作用驱动主阀动作。适用于大口径、大排量及高压系统。先导式安全阀与导阀采用无缝管接通,由先导阀来感测被控压力信号并控制主阀的启闭。其动作过程是:当安全阀的阀前压力低于整定压力时,先导阀整定弹簧将阀芯推向阀座密封面,气体介质经导阀进口进入主阀阀芯上腔,使阀芯下移贴紧阀座,导阀和主阀都处于无泄漏的关闭状态;当阀前压力达到或高于整定压力时,介质压力克服整定压力,弹簧将导阀阀芯推向上移,导阀受力面积由阀芯面积转化为活塞受力面积,受力面积增加上升力增大,导阀开启。主阀阀套上腔内的气体从导阀出口排出,主阀打开,介质迅速排放,活塞行程到大位置。当介质压力排放到一定压力时,通过活塞阻尼孔的介质压力使活塞上下两端产生面积压差平衡,启闭压差由活塞上下两端面积压差平衡实现,当阀前压力降回到工作压力以下时,在较小弹簧力作用下,阀芯下移实现其密封。导阀关闭,主阀也就随之而关闭。
