The medium delivered by DN2200 pneumatic ball valve is generally not pure drinking water. They are installed at the outlet of pneumatic 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 pneumatic ball valve. If the dirt stains on the pipe wall for a long time, it is difficult to clean it, So we need to clean the dirt on the inner wall of the pneumatic 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 pneumatic ball valve is also called pipeline compensation joint. It is a new product connecting pump, valve, pneumatic ball valve and other equipment with pneumatic ball valve. They are connected by bolts to make them become a whole with a certain displacement. Since DN2200 pneumatic ball valve can compensate the displacement of pneumatic ball valve, it has become the first choice for pneumatic ball valve to transmit and compensate the displacement. However, with the increase of service life and the difference of service environment, the DN2200 pneumatic ball valve will scale inside, resulting in low delivery efficiency of the pneumatic ball valve and serious blockage. The scaling of DN2200 pneumatic ball valve is caused by natural blockage and natural accumulation. This kind of dirt is usually removed by using 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 pneumatic ball valve can be cleaned. (It should be noted that it must be weakly acidic, otherwise it will affect the service life of the pneumatic ball valve.) The above is a brief description of the methods that can remove the dirt on the pipe wall of DN2200 pneumatic ball valve. Of course, there are more ways to deal with it through chemical and physical reactions. For more information, contact Dongfeng
