Treatment of valve cover leakage
Thread Content
Dear experts: The valve cover is leaking oil, and it’s not possible to shut down the process immediately. Please consider whether there is any way to address this issue with the equipment； For example, with new technologies like sealant, I’m looking for recommendations. The bolts have been tightened, but it’s still leaking. ! ! !
Make a jacket that is fastened to the flange seal of the large cover with bolts
In the picture above, the positions of the valve covers vary depending on their type
Generally, leakage occurs at the gasket on the large cover, and tightening the bolts doesn’t help. It’s difficult to deal with this situation while operations must continue; one solution is to use a jacket to seal the gap around the gasket on the large cover. However, if the pressure is high, leakage will still occur at the bolts of the large cover. It’s best to fill that area with some type of setting agent
Thank you for the reply. Does the original poster have any pictures? I don’t quite understand this. Do the manufacturers that produce this have any contact information?
This requires a type of clamping sleeve made according to the diameter of the valve’s cover on site and the width of the two flanges, which is then tightened using bolts
If there is an oil leak, using steel strips to seal it is likely to be ineffective. It is recommended to use a pressure-sealing clamp, and then apply glue with a glue stick; this should be able to resolve the leak.
For making molds, injecting glue will solve the problem
