比例式减压阀和先导式减压阀的区别是:

比例式减压阀是采用固定比例来进行减压的阀门,安装在给排水管网中,防止管道的压力过大造成爆管。主要特点是阀后压力与阀前压力呈一定比例,即当阀前压力变化时,阀后压力按比例相应变化,实现,既可减静压   又可减动压。标准压力比为2:1、3:1、4:1、5:1、3:5:2等并可根据用户的要求设计特殊比例的减压阀。

先导式减压阀是采用控制阀体内的启闭件的开度来调节介质的流量,将介质的压力降低,同时借助阀后压力的作用调节启闭件的开度,使阀后压力保持在一定范围内,在进口压力不断变化的情况下,保持出口压力在设定的范围内,保护其后的生活生产器具。本类阀门在管道中一般应当水平安装
