Scaling phenomenon of pneumatic ball valves in domestic sewage pipelines We see a lot of pneumatic ball valves in domestic sewage pipelines in our daily life. It can be seen that the scope of use of pneumatic ball valves in domestic sewage pipelines is very wide. Due to different media used in daily use, scaling phenomenon will inevitably occur over a long period of time. Once scaling occurs, There will be some problems in the use of the pipeline after a long time, and the service life of the pipeline will become shorter. So, how to deal with the scaling phenomenon of the pneumatic ball valve in the domestic sewage pipeline and extend the service life of the pipeline? Now let me tell you something.
The pneumatic ball valve of domestic sewage pipeline has the characteristics of thermal expansion and cold contraction, so there are several ways to deal with its scaling.
1. High pressure jet can be used. This method is suitable for pipes below medium size. Some auxiliary equipment of the pipe itself is used for descaling, and a sprinkler is used to spray water to descale.
2. The mechanical scraping method can be used. This method is suitable for the use of large pipelines. Mechanical scraping is used to scrape 100-150 meters at a time. Some pipelines have a long distance. At this time, the pipeline should be cleaned in several stages, one by one. This method must make the pipeline disconnected for implementation, and it must be able to be carried out under the condition of water cut-off.
3. A pipe washer can be used for flushing. Special tools are used to scrape off the scale in the pipeline. This method can clean the scale with different hardness, that is, it can effectively remove the scale in the pipeline, and it can also clean the newly installed drainage pipeline with high efficiency.
