The main cause of leakage of carbon steel gate valve

valve is a steel industrial valves, are widely used in petroleum, chemical, power plants and other industriesWith automated, easy operation, long life and other advantages, but in the course of their own or because of the influence of external factors, carbon steel gate valve will leak case appearsSo, in the end is what causes carbon steel gate valve leak it? There are the following common causesCarbon steel gate valve leakagemain reasons5:01, the wedge sealing ring machining accuracy due to the low carbon steel gate valve, internal leakage occurs as long as the selected brand valve, then the general zero parts quality is good, so it will not lower the machining accuracy of the sealing ring occursa 2, resulting in the production of unstable operating conditions drain valve, valve operating environment requirements are relatively high, if the pressure and temperature environment is unstable, the variation width is too large, then the seal ring is subjected to pressure shocks large, it is easy to appear deformed, in the end will lead to valve leakage3, valve repair mass difference resulting in a drain valve, when some maintenance staff in the valve, the seal ring seal surface is not clean, the presence of impurities affect the operation of the valve, the long run will scratch the sealing surface, so that causing it to leak4, the wedge sealing ring results in corrosion media gate leakage, long-term operation of the valve, under the influence of the medium, the sealing ring susceptible to corrosion, corrosion to a certain extent, damage to the sealing ring, so that a leak in the valve case on the5, the defective valve, the valve body is present if porosity, slag inclusions, cracks, blisters and other problems, then the process is easy to use valve leakage occursIn short, carbon steel gate valve leak is a relatively common type of problem, if a leak occurs, it will endanger the safety of equipment and personnel, so to promptly identify the cause and resolve the issue
