DB30-2-L5X/31.5 立新减压阀原厂

立新减压阀原厂DB30-2-L5X/31.5工作原理：

减压阀出厂时，调节弹簧处于未压缩状态,此时主阀瓣和副阀瓣处于关闭状态,使用时按顺时针转动调节螺钉,压缩调节弹簧,使膜瓣移顶开付阀瓣,介质由a孔通过付阀座到b孔进入活塞上方,活塞在介质压力的作用下,向下移动推动主阀瓣离开主阀座,使介质流向阀后.同时由c孔进入膜片下方,当阀后压力超过调定压力时,推动膜片上移压缩调节弹簧,付阀瓣随之向关闭方向移动,使流入活塞上方的介质减小,压力也随之下降,此时的主阀瓣在主阀瓣弹簧力的推动上下移,使主阀瓣与主阀座的间隙减小,介质流量也随之减小,使阀后压力也随之下降到新的平衡,反之当阀后压力低于调定压力时,主阀瓣与主阀座的间隙增大,介质流量也随之增加,使阀后压力也随之ZG达到新的平衡.

减压阀的安装与维护蒸汽减压阀的安装与维护应注意以下事项：

手轮、手柄及传动机构均不允许作起吊用，并严禁碰撞。

双闸板闸阀应垂直安装（即阀杆处于垂直位置 , 手轮在顶部 )。

带有旁通阀的闸阀在开启前应先打开旁通阀（以平衡进出口的压差及减小开启力 )。

带传动机构的闸阀，按产品使用说明书的规定安装。
