安全阀的分类：
1. Hammer杠杆安全阀
重锤杠杆安全阀是使用重锤和杠杆来平衡阀门的力量。根据杠杆原则，它可以使用较小的质量锤子通过杠杆的扩大效果来获得大力，并调整安全阀的压力通过重锤的位置（或重锤的质量）的位置。
2.弹簧微型安全阀
弹簧微启用安全阀是使用压缩弹簧的力来平衡阀门上的力的力。可以通过旋转其上方的调节螺母来调节螺旋圆弹簧的压缩。使用这种结构，可以根据需要校正安全阀的压力（设置）压力。弹簧微型安全阀的结构是轻巧和紧凑的，灵敏度相对较高，并且安装位置不限。
3.脉冲安全阀
脉冲安全阀由主阀和辅助阀组成。辅助阀的脉冲作用驱动主阀运动，其结构很复杂。它通常仅适用于锅炉和压力容器，并具有大量安全泄漏。
