The medium delivered by DN2200 electric ball valve is generally not pure drinking water. They are installed at the outlet of electric ball valve and pump to discharge sewage from the factory. For example, chemical plants sometimes discharge acid-base fluid. After a long time, there will be some dirt inside DN2200 electric ball valve. If the dirt stains on the pipe wall for a long time, it is difficult to clean, So we need to clean the dirt on the inner wall of the electric ball valve regularly. It is very difficult to clean. We need to use chemical methods to clean it. What are the main cleaning methods?
DN2200 electric ball valve, also known as pipeline compensation joint, is a new product connecting pump, valve, electric ball valve and other equipment with electric ball valve. They are connected by bolts to make them become a whole with a certain displacement. Since DN2200 electric ball valve can compensate the displacement of electric ball valve, it has become the first choice for electric ball valve to transmit and compensate the displacement. However, with the increase of service life and the difference of service environment, the DN2200 electric ball valve will scale inside, resulting in low transmission efficiency of the electric ball valve and serious blockage. The scaling phenomenon of DN2200 electric ball valve is caused by natural blockage and natural accumulation. This kind of dirt is usually removed by steel wire balls and cleaning cloth with clean water for many times.
The other is scaling caused by chemical reaction. For example, there are two main elements caused by general chemical reaction. One is iron ion, the other is calcium ion. They are the cause of scaling. So in this case, it is necessary to use some weak acid solutions to clean. Use acids, iron ions and calcium ions to start an oxidation-reduction reaction, In this way, the dirt in the DN2200 electric ball valve can be cleaned. (It should be noted that it must be weakly acidic, otherwise the service life of the electric ball valve will be affected.) The above is a brief description of the methods that can remove the dirt on the wall of DN2200 electric ball valve, and of course, there are more methods to deal with it through chemical and physical reactions.
