Will rust of the electric ball valve affect the water quality? Rust of the electric ball valve pipeline will reduce the water delivery capacity, increase the power consumption, and thicken the growth ring in the electric ball valve pipeline year by year, which will not only affect the water supply quality, but also seriously affect the water flow section of the original electric ball valve pipeline, reduce the water delivery capacity, and also increase the resistance of the electric ball valve pipeline, resulting in a decrease in the water supply pressure, In order to ensure the water pressure of water supply service, high lift pump must be used to increase the water pressure, which not only wastes electric energy, but also increases the water leakage.
The corrosion in the electric ball valve pipe has an impact on the water supply quality. Due to the long-term corrosion of water, a growth ring containing various components and bacteria is formed on the inner wall of the electric ball valve pipe. Its thickness is mainly affected by the water quality, the pipe materials of the electric ball valve and the service time. The various components and bacteria contained in the rust will dissolve in the water, causing secondary pollution to the water quality Also, after the electric ball valve pipeline is scaled, the water quality is secondary polluted, so that the residual chlorine in the water is consumed by organic substances, so the total number of bacteria increases. There are pathogenic bacteria in these bacteria. There are also bacteria that can corrode the electric ball valve pipeline. Some of these various bacteria seriously affect the water quality, while others aggravate the corrosion of the electric ball valve pipeline, thus shortening the service life of the electric ball valve pipeline. In line with the enterprise principle of cooperation and dedication, and users' peace of mind, our factory devotes excellent products and perfect services to our customers with the enterprise spirit of honesty, realism and pragmatism.
