The importance of ball core for pneumatic ball valve
The author: Time:2019/11/22

        球芯对于气动球阀来说是关键件,球表面的尺寸精度达到四级,形状精度达到八级,表面粗糙度R在0.4以下。安放球芯时,必须用胶布保护其表面,严禁磕碰,否则会拉伤密封表面,造成泄漏,并降低密封润座的使用寿命。

气动球阀


       由于阀体进口处直径比球芯端面距小,因此球芯不能水平放入阀体,必须将球芯立着,让一端先进入阀体内腔,然后将球芯在阀体内腔旋转90度,使其处于水平位置。因球芯两端分别有光孔和花键孔,所以在安放球芯时,必须注意球芯与阀体装短轴、传动轴部分的位置关系。
