How to deal with the issue of misalignment in plug valves
Thread Content
Since work started recently, it has been found that the misalignment of the check valves is quite severe; I’m wondering if anyone has experience with this issue. How to correct it? What are the things to pay attention to in daily life?
Doesn’t anyone know? Has this kind of thing happened? I’m trying to figure it out on my own; I hope someone can tell me
We have never encountered a situation where the plug valve of the manufactured unit was out of alignment; it is necessary to investigate the causes of this misalignment and take measures to address it. Misalignment occurred during installation, and adjustment was mainly achieved by taking advantage of weld contraction – that is, a gap was created in the weld on the side with the deviation, it was polished clean, and then rewelded. The deviation was thus corrected due to weld contraction. Additionally, depending on the direction of the deviation, the gasket of the plug valve could be made thicker on one side and thinner on the other, allowing for slight adjustments to the plug valve’s installation so as to meet the alignment requirements first.
