闸阀研磨操作技术 | 2011-1-14 8:26:00

1、闸阀研磨前必须先检查试压，确定是否能研磨修复，然后打下标记拆卸（当关闭闸板时，闸板过低、减小密封面积或密封面严重碰伤、变形均无法研磨修复，但亦可用补焊修磨）。
2、将闸板放在研磨机调整板上，旋动底板调整螺丝钉，使其研磨面呈水平位置。在研磨盘上均匀地涂上研磨砂，放在闸板或通过闸板口放进阀座的研磨面上，降下磨杆，连接三角弧形磨头，磨杆与磨盘留1~2mm的间隙，紧定磨杆套固定螺钉，按起动按钮，使磨杆按顺时针方向旋转，带动研磨盘以自身重压力作无规则的摆动。磨好一面后，用同样方法研磨另一面。
3、单闸板闸阀最好采和先研磨闸板的方法。先把阀座密封圈粗磨平整好两面，再将闸板平面均匀涂上显示剂（显示剂用红丹调机油即可），按拆卸时打上的标记，端正地放入阀座，用木柄敲打闸板上端，使闸板与阀座紧合；然后用左手将闸板往上提，用右手握锤轻轻敲击阀体，闸板便可取出；取出后根据显示出的凸起部分进行刮削；刮削要按闸板的圆周方向进行；刮削一次完毕，用棉纱擦净，再涂显示剂刮削，循环往复，直到闸板与阀座接触面分布均匀为止；最后用一块标准平面研磨盘，涂上显示剂，检查闸板顶端未参加工作的凸起部分，进行顶端刮削，待顶端与闸板成一平面后，即可进行研磨。双闸板可直接进行研磨。
4、磨料以碳化硅为宜，调剂时可用25%的机油、75%的煤油，浓度以不流失为宜。研磨时，按粗、中、细的先后顺序进行研磨。研磨时间视闸阀的好坏程度而定。
5、研磨中必须勤检查，研磨机的蜗轮转动部分，必须经常注油保持润滑。
6、研磨完毕。
