How to maintain the pneumatic butterfly valve?
Since the chemical corrosion of metal depends on temperature, the mechanical load of friction parts, the sulfide contained in lubricating materials and its acid resistance, the duration of contact with the medium, the catalytic effect of metal in the nitriding process, and therefore, the anti-corrosion methods (or measures) of metal valves and the application of synthetic material valves have become one of the themes of current valve research.
Corrosion prevention of metal valves can be understood as coating a protective layer (such as paint, pigment, lubricating material, etc.) on metal valves to protect them from corrosion, so that they can be manufactured, stored, transported or processed. Used. The whole process is free of corrosion. The anti-corrosion method of metal valves depends on the required protection period, transportation and storage conditions, valve structural characteristics and materials. Of course, it is appropriate to consider the economic effect of removing anti-corrosion.
