Orbital carbon steel ball valve is widely used in industry, for a medium such as water, solvents, acids and natural gas are better able to adapt to the timely was in bad working conditions can also play a great role, but no matter how good, orbital carbon steel ball valves are all need to do daily maintenance work at ordinary times, if do not maintain for a long time, the equipment is easy to appear problem. The following points is orbit type carbon steel ball Industrial Valves daily maintenance and matters needing attention. First of all, track type ball valve for maintenance and repair, lubricated regularly for ball valves, want to go to the lubricating oil once a year at least, if there is leakage, found that the valve stem so that ball valve need lubricating oil. And stem lubrication at least four times a year. The number of lubrication to be decided according to the number of equipment operation, operating the more frequent then more need lubrication. Second, check rail type carbon steel ball valve leakage situation, if the inner leakage, so will not only affect the performance of the equipment, even can bring safe hidden trouble. So the leakage situation of carbon steel ball valves should be inspected regularly, if found the leak, timely find out the reason and solve the problem, a rotary carbon steel ball valve stem packing leaking out when to add and change. Finally, if carbon steel ball valve malfunction, so be sure to look for professional maintenance personnel to handle, if maintenance also can't solve the problem, the new carbon steel ball valve to be replaced. In a word, a rotary carbon steel ball valves must be to do routine maintenance, so that to prolong the service life of equipment is very good. In addition to carbon steel ball valve must choose big manufacturer of choose and buy equipment, so that the quality is assured, have a lower chance of failure. when the choose and buy, we saw most is 'stainless steel valves, stainless steel, however there is a quality, or common used for stainless steel ball valve of stainless steel 304 stainless steel, austenitic stainless steel, etc. , which quality is better and more durable? A, austenitic stainless steel and 304 stainless steel because of the particularity and difference of application environment, so the valve material must be very exquisite, austenitic stainless steel and 304 stainless steel is more widely used in stainless steel material, the former strong toughness and plasticity, add sulfur, calcium and other elements can produce good machinability, the erosion resistance and corrosion resistance of 304 stainless steel is more outstanding, so often used for kitchen waste slag line and industrial wastewater treatment plant. Second, heat-resistant steel and low temperature resistant stainless steel ball valve working environment temperature difference can be as high as 1000 degrees Celsius, can be as low as - at low temperature 296 degrees Celsius, high temperature can reach 800 degrees Celsius, so choose what kind of material more durable stainless steel valve, but also the heat resistance and low temperature resistance. Piping system above 300 degrees Celsius is of characteristics of heat resistant steel, and steel is suitable for - at low temperature 29 and - 296 degrees Celsius, within the scope of the the - 196 to - 296 for cryogenic environment. material temperature tolerance is very important, low temperature environment material brittleness increases, volume shrinkage, easy to cause the valve leakage, therefore must according to the environmental temperature selecting suitable material of the valve. To ensure that the application of the stainless steel ball valve life, it is important to buy the most suitable for the working environment of valve, otherwise the valve pressure ability is insufficient, excessive friction force that can lead to premature failure of the valve.
