Since I haven't paid much attention to the reversing valve in the asphalt mixing plant before, I am helpless about the failure of this device. In fact, the failure of the reversing valve is not very complicated. As long as you know a little about it, you will definitely know how to deal with it?

There are also reversing valves in asphalt mixing plants, and its failures are nothing more than common problems such as untimely reversing, gas leakage, and electromagnetic pilot valves. Of course, the causes and solutions corresponding to different problem manifestations are also different. For the phenomenon of untimely reversing of the reversing valve, most of them are caused by poor lubrication of the valve, stuck or damaged springs, oil or impurities stuck in the sliding parts, etc. For this, it is necessary to check the state of the oil mist device and the viscosity of the lubricating oil. If there is a problem, the lubricating oil or other parts can be replaced. After the asphalt mixer plant has been running for a long time, its reversing valve is prone to wear of the valve core seal ring, damage to the valve stem and valve seat, which leads to gas leakage in the valve. At this time, the correct and effective way to deal with it is to replace the seal ring, valve stem and valve seat, or directly replace the reversing valve to overcome the leakage problem.
