Ceramic double Gate discharging valve has good sealing performance, but after using it for a long time, there will be problems, how to solve it?
1.The ceramic double gate discharging valve with the gas piping system, which can blown to the valve cavity, so as to solve the problem that it is easy to accumulate dust when installing the vertical pipeline horizontally.
2.Regular checks and maintenance to avoid problems
3.When starting to use, the valve should work on the maximum opening as far as possible, so as to facilitate the removal of impurities in the pipeline, such as welding slag, iron rust, iron wire, cloth strips and so on, so as to prevent sticking.
4. In the design and manufacture, widen the sealing width of the ceramic disc , too narrow sealing surface may lead to local leakage and eventually lead to wear failure of the overall sealing surface.
5. Increase the spring preload between the two discs, so as to resist the pressure of the medium and prevent valve leakage.
