In order to make the copper valve better used, it needs to be well maintained, and the cleaning of its parts is particularly important. Before the valve parts are assembled, they must be polished and degreased to ensure that there are no machining burrs on the surface. After the degreasing is completed, it is necessary to pay attention to pickling and passivation, and then rinse it with pure water. Finally, dry it with a non-woven fabric. At the same time, it should be noted that the surface of the parts such as wire hair cannot be retained until there is no dirty color. Only after the parts of the copper valve are cleaned, the use will be smoother, and many problems during use can be prevented.
Bronze is rarely used in modern industry, generally only brass is used. Because bronze is not as good as brass in mechanical properties, and the price of bronze is higher than that of brass, bronze is rarely used in machinery because of its soft texture. The fineness is mainly used in machinery, such as bearing bushes, seals and other parts.
