|
|
|
|
|
|
ZJHM精小型气动套筒调节阀，由新型的气动多弹簧执行机构和低流阻精小型套筒阀组成。
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
是符合IEC标准的新一代通用调节阀，被应用于石化，轻纺等行业中。
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
1、 采用平衡型阀芯，不平衡力下，允许压差大，操作稳定。
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
2、 阀芯导向面大，可改善由涡流和冲击引起的振荡。
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
3、 比普通的单、双座调节阀噪声降低10dB左右。
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
4、 结构简单，装拆维修方便。
