气动阀门工作原理
气动阀门是按力矩平衡原理工作的，当通入波纹管2的信号压力P1增加时，使主杠杆3绕支点转动，使喷嘴挡板9靠近喷嘴，喷嘴背压经单向放大器8放大后，通入到执行机构薄膜室的压力增加，使阀杆向下。并带动反馈杆绕支点转动，反馈凸轮也随之作逆时针方向转动，通过滚轮使副杠杆4绕支点转动，并将反馈弹簧拉伸，弹簧对主杠杆3的拉力与信号压力用在波纹管上的力达到力矩平衡时，仪表达到平衡状态。执行机构的阀位维持在一定的开度上，一定的信号压力就对应于一定的阀位开度。以上作用方式为正作用，若要改变作用方式，只要将凸轮翻转，A向变成B向等，即可。所谓正作用，就是信号压力增加，输出压力亦增加；所谓反作用，就是信号压力增加，输出压力则减少。一台正作用执行机构只要装上反作用，就能实现反作用执行机构的动作；相反，一台反作用执行机构只要装上反作用，就能实现正作用执行机构的动作。
