Why is the electric ball valve blocked. The electric ball valve can compensate the displacement of the pipeline, and now it has become the first choice for pipeline transmission to compensate the displacement. With different service environments and increasing service life, the steel electric ball valve will scale and cause serious blockage. Why is the electric ball valve blocked? When it comes to scaling of steel electric ball valves, there are generally two types of scaling: one is caused by chemical reaction, and the other is natural blockage. Generally, there are two kinds of elements caused by chemical reaction, one is iron ion, the other is calcium ion, which is often the cause of scaling. In this case, it is necessary to use some weak acid solutions to clean the acid, iron ion and calcium ion in an oxidation-reduction reaction, so that this kind of dirt can be cleaned. Remind me that it must be weakly acidic, otherwise it will affect the service life of the pipeline. Another situation is natural accumulation. This kind of dirt is usually removed by using steel wire balls and cleaning cloth with clean water for many times.
In order to avoid pipe blockage in the construction of construction and installation works, before the installation of steel electric ball valve, the pipe cavity shall be carefully dredged, debris shall be removed, and drainage fittings shall be properly used according to the specifications; When installing the steel electric ball valve, ensure that the main pipe is correctly installed with the corresponding slope, meet the design requirements and specifications, and take measures such as sealing the drain pipe orifice with cement mortar. During the use of steel expansion joint, the most common blockage is the sundries and mud thrown into the trap, or even the mortar that is easy to deposit and agglomerate. This is because during the construction, some people try to dump the cleaned mortar at will, or sweep the sediment into the floor drain when cleaning the floor. It is very difficult to clean up. The solution is to wrap or plug the reserved pipe orifice.
In order to effectively ensure that there will be no deposition and caking in the water trap, it is advisable to temporarily open the blind cover at the bottom of the trap during construction, so that mortar and other sundries cannot stay in the pipe. The blind cover can be tightened until the construction site is cleaned up, so that other foreign matters in the pipe can be found and removed in time, providing a stable working environment for the steel expansion device. Only when we take precautions at ordinary times can we minimize the probability of pipe blockage and make steel expansion joints bring convenience to people's lives in normal work.
