安全阀的分类
安全阀按不同方法的分类如下：
① 按其整体结构及加载机构的不同可分为杠杆重锤式（通常用于较低压力，一般安装在设备上）、弹黄式和控制式；
② 按阀瓣开启高度与阀流通直径之比可分为微启式、中启式和全启式安全阀； ③ 按气体排放的方式可分为全封闭式、半封闭式和敞开式；
④ 按有无背压平衡机构分为背压平衡式和常规式；
⑤ 按作用原理分为直接作用式和非直接作用式（包括先导式和带动力辅助装置的）。
1.2 安全阀选型说明
安全阀的形式和种类较多，对不同的场合，宜选用以下形式的安全阀：
① 排放气体或蒸汽时，选用全启式安全阀；
② 排放液体时，一般选用微启式安全阀；
③ 排放水蒸汽或空气时，可选用带扳手的安全阀；
④ 对设定压力大于 3mpa、温度超过 235℃ 的气体用安全阀，则应选用带散热片的安全阀，以防止泄放介质直接冲蚀弹簧；
⑤ 一般易燃、易爆或有毒的介质应选用封闭式，蒸汽或惰性气体等可以选用不封闭式；
⑥ 排放有剧毒、强腐蚀、极度危险的介质，应选用波纹管安全阀；
⑦ 高背压的场合，宜选用背压平衡式或导阀控制式安全阀。
