What are the conditions for stainless steel valves to be sealed?
The valve is used in the chemical system air separation equipment, and the sealing surface is mostly made of stainless steel. In the grinding process, due to improper selection of abrasive materials, the grinding method is not correct, which not only reduces the valve production efficiency, but also affects the product quality considerably. According to the characteristics of stainless steel materials, we have chosen to have strong labor intensity and wear resistance, and still affect the product quality after the abrasive grains are broken during processing. In recent years, we have studied the grinding materials, such as white corundum and chrome oxide, and the selection of grinding tools and grinding methods. The particle size is mainly selected from w40, w14, w7 and W5. Four are appropriate. Through the test, and has been promoted and applied in the actual production, it not only improves the quality of the sealing surface, but also improves the production efficiency and obtains good results.
