Abstract

一种压力卸放阀及麻醉机，压力卸放阀包括操作部(3)、阀体(11)、阀座(12)、电动控制部以及阀芯组件；操作部(3)的至少部分结构设置于阀体(11)外部；阀座(12)具有阀口(12a)；阀芯组件包括阀片(21)以及第一弹性件(22)，第一弹性件(22)能够在操作部(3)的驱动下对阀片(21)施加朝向阀口(12a)的作用力；电动控制部选择性地向阀芯组件、阀座(12)或操作部(3)输入驱动力，以改变阀片(21)与阀口(12a)之间的相互作用力。APL阀，自动状态下，电动控制部输入驱动力，阀片(21)在驱动力的作用下封闭阀口(12a)；手动状态下，电动控制部无动力输入。当麻醉机泄露自检时，通过系统程序控制电动控制部输入驱动力，APL阀由手动状态切换至自动状态，无需人工干预APL阀，实现麻醉机全自动泄露自检。
