With the development of society, the country pays more and more attention to the construction of municipal affairs. Therefore, as an important equipment in the development and construction of municipal affairs, asphalt mixing plants are becoming more and more popular and the frequency of use is increasing. Asphalt mixing plants will encounter some faults more or less during use. This article briefly introduces how to solve the fault of the reversing valve in the asphalt mixing plant.

If there is a problem with the reversing valve in the asphalt mixing plant, the manifestation is mainly that the valve cannot be reversed or the reversing action is slow. There may also be gas leakage, electromagnetic pilot valve failure, etc. Generally speaking, when encountering such a problem, the first thing to consider is to find the root cause of the fault, so that the fault can be accurately and effectively eliminated.
If the reversing valve cannot be reversed or the reversing action is relatively slow, the user can consider the reasons such as poor lubrication, spring jamming, or oil impurities jamming the sliding parts. At this time, the user can first check the oil mist device to check the working status, and then confirm the viscosity of the lubricating oil. If a problem is found or it is necessary, the lubricating oil or spring can be replaced.
Gas leakage is usually caused by the reversing valve of the asphalt mixing plant working at a high frequency for a long time, which causes wear of the valve core seal ring and other parts. If the seal is not firm, gas leakage will occur naturally. At this time, the seal ring or valve stem and other parts should be replaced.
