阀瓣频跳或振动：主要是由于弹簧刚度太大。应改用刚度适当的弹簧；调节圈调整不当，使回座压力过高。应重新调整调节圈位置；排放管道阻力过大，造成过大的排放背压。应减小排放管道阻力。不到规定压力开启：主要是定压不准；弹簧老化弹力下降。应适当旋紧调整螺杆或更换弹簧。R900973475DBE10-5X/200YG24K4VR900923188DBE10-5X/200YG24NK4MR900714301DBE10-5X/200YG24NK4VR900536997DBE10-5X/200YG24NZ4MR900521576DBE10-5X/200YG24Z4MR900517820DBE10-5X/200YG24Z4VR901069892DBE10-5X/315XYG24K4MR900924161DBE10-5X/315XYG24NK4MR900579202DBE10-5X/315XYG24Z4MR900916124DBE10-5X/315YG24K4MR900978551DBE10-5X/315YG24K4VR900949005DBE10-5X/315YG24NK4MR901058477DBE10-5X/315YG24NK4VR900534917DBE10-5X/315YG24NZ4MR900900524DBE10-5X/315YG24NZ4VR900528731DBE10-5X/315YG24Z4MR900533043DBE10-5X/315YG24Z4VR900704605DBE10-5X/350XYG24K4MR900967563DBE10-5X/350YG24K4MR900957752DBE10-5X/350YG24NK4MR900538008DBE10-5X/350YG24NZ4MR900539401DBE10-5X/350YG24Z4MR900926160DBE10-5X/350YG24Z4VR900916125DBE10-5X/50XYG24K4M)
