The electric ball valve has its own characteristics in material selection. The double flange electric ball valve can not only be used in the circulating water pipeline of the power plant, but also in the powder transport pipeline, waste and miscellaneous transport pipeline and lime slurry pipeline. The media used in these special pipelines are highly corrosive and require the pipeline to be highly wear-resistant. So how our company's double flange electric ball valve can do this, first of all, we should pay attention to the design, The original valve seal ring was changed to graphite flexible packing seal ring, and the guide pipe was thickened by strengthening treatment near the guide pipe of the electric ball valve. In the manufacturing process, high-precision lathe is used to form, which greatly improves the sealing of the pipeline.
The electric ball valve not only has these unique characteristics in design, but also has its own characteristics in material selection. First, high manganese wear-resistant steel is selected as the material of the inner guide sleeve. This wear-resistant plate has an ideal wear-resistant effect at - 40 ℃ to 500 ℃. The effect of using it as the guide sleeve is very obvious, The inspection results of our company's professionals in pipeline maintenance show that the annual loss of the guide sleeve is less than 5%. Our company manufactures high-quality wear-resistant guide sleeve inside the electric ball valve. According to the use environment, the wear-resistant high-quality steel plates selected are: WNM306A, WAM306B, WAM306C, WNM400A, WNM400B, WNM400C, and WNM316L with good welding performance.
