贺德克比例减压阀PDR08-01-C-N-200-24PG-8.8

导阀的开启都是利用**部的调节螺栓顺时针方向拧动，使弹簧缩产生的弹力，使导阀膜片向下凹陷，作用在导阀连杆上的力，使之向下位移打开导阀。当导阀开启后，上游进汽管段A腔的蒸汽通过α通道(供汽调节通道)，经过导阀进入导阀环形汽腔，由β通道直接送到下面的活塞汽缸上腔。在A腔蒸汽不断的供给下，压力持续升高，推动活塞下行打开主阀，这时蒸汽源源不断从A腔流至B腔。当下游出口管段B腔负荷满足的情况下，余多的蒸汽又使B腔内的压力不断升高。不断升高的压力通过γ通道(压力感应通道)反馈到导阀膜片下腔，使导阀膜片向上突起，克服了上部调节弹簧的压力，导阀被关小或关闭。从而，关小或关闭来自上游α通道的蒸汽源。当活塞汽缸上腔压力下降时，在下面复位弹簧的作用下，主阀被关小或关闭，这时B腔内的压力开始下降，这样周而复始达到调压的目的
