原装Bihl+Wiedemann BWU1891 总线模块技术参数
冲量安全阀动作后主安全阀不动作这种现象通常被称为主安全门的拒动。主安全门拒动对运行中的锅炉来说危害是非常大的，是重大的设备隐患，严重影响设备的安全运行，一旦运行中的压力容器及管路中的介质压力超过额定值时，主安全门不动作，使设备超压运行极易造成设备损坏及重大事故。在分析主安全门拒动的原因之前，首先分析一下主安全门的动作原理。如图1，当承压容器内的压力升至冲量安全阀的整压力时，冲量安全阀动作，介质从容器内通过管路冲向主安全阀活塞室内，在活塞室内将有一个微小的扩容降压，假如此时活塞室内的压强为P1，活塞节流面积为Shs，此时作用在活塞上的f1为：f1=P1×Shs……………………假如此时承压容器内的介质的压强为P2，阀芯的面积为Sfx，则此时介质对阀芯一个向上的作用力f2为：f2=P2×Shx..............通常安全阀的活塞直径较阀芯直径大，所以式与式中Shs＞SfxP1≈P2假如将弹簧通过阀杆对阀芯向上的拉力设为f3及将运动部件与固定部件间摩擦力（主要是活塞与活塞室间的摩擦力）设为fm，则主安全门的动作的先决条件：只有作用在活塞上的作用力f1略大于作用在阀芯上使其向上的作用力f2及弹簧通过阀杆对阀芯向上的拉力f3及运动部件与固定部件间摩擦力（主要是活塞与活塞室间的摩擦力）fm之和时，即：f1＞f2+f3+fm时主安全门才能启动。

原装Bihl+Wiedemann BWU1891 总线模块技术参数
冲量安全阀动作后主安全阀不动作这种现象通常被称为主安全门的拒动。主安全门拒动对运行中的锅炉来说危害是非常大的，是重大的设备隐患，严重影响设备的安全运行，一旦运行中的压力容器及管路中的介质压力超过额定值时，主安全门不动作，使设备超压运行极易造成设备损坏及重大事故。在分析主安全门拒动的原因之前，首先分析一下主安全门的动作原理。如图1，当承压容器内的压力升至冲量安全阀的整压力时，冲量安全阀动作，介质从容器内通过管路冲向主安全阀活塞室内，在活塞室内将有一个微小的扩容降压，假如此时活塞室内的压强为P1，活塞节流面积为Shs，此时作用在活塞上的f1为：f1=P1×Shs……………………假如此时承压容器内的介质的压强为P2，阀芯的面积为Sfx，则此时介质对阀芯一个向上的作用力f2为：f2=P2×Shx..............通常安全阀的活塞直径较阀芯直径大，所以式与式中Shs＞SfxP1≈P2假如将弹簧通过阀杆对阀芯向上的拉力设为f3及将运动部件与固定部件间摩擦力（主要是活塞与活塞室间的摩擦力）设为fm，则主安全门的动作的先决条件：只有作用在活塞上的作用力f1略大于作用在阀芯上使其向上的作用力f2及弹簧通过阀杆对阀芯向上的拉力f3及运动部件与固定部件间摩擦力（主要是活塞与活塞室间的摩擦力）fm之和时，即：f1＞f2+f3+fm时主安全门才能启动。
