作用原理和结构说明

1、阀前进口介质压力从阀瓣和阀体密封圈开启间隙进入体腔使介质压力流满波纹管的组合箱,波纹管和弹簧因受介质压力的挤压而压缩,阀瓣随着阀杆位移,阀瓣产生对阀体密封圈的关闭,将阀前介质截止,不作阀后介质压力的补充。当阀后的介质压力降低,波纹管因受调节弹簧的径项力,使波纹管叠纹变形,阀杆将阀瓣顶开。使介质通过阀体密封圈补充阀后压力的降低。 
2、波纹管减压阀是由阀体、阀盖、阀瓣、阀体密封圈、阀杆、波纹管、调节弹簧等零件组成,体腔进口组装有阀瓣、阀体密封圈和辅弹簧,辅弹簧是保持阀瓣和阀体密封圈自动的密封,出口体腔组装弹性密封元件(波纹管)即保证阀后介质压力的泄漏和克服压力不均匀度的补偿。螺钉是调整弹簧负荷压力减压阀工作性能。
