What's the reason why carbon steel gate valve leak

by:Mech     2020-05-19
Carbon steel gate leakage is the reason why carbon steel gate Industrial Valves is a kind of industrial valves, in petroleum, chemical industry, power plant and other industries widely used. With automation, easy to operate, long life and other advantages, but in use process because of its own or external factors, the carbon steel gate Industrial Valves leakage would happen. So, exactly what causes carbon steel gate valve leakage? Basically has the following common cause. A low, wedge ring processing precision result in carbon steel gate Industrial Valves leakage occurs, want to choose the gate of the big brands, so general spare parts quality is good, also won't appear so ring processing precision is low. Second, the instability of production operating conditions lead to gate valve leakage, gate to the requirement of working environment is relatively high, if the pressure and temperature environment is unstable, change is too big, so sealing ring to withstand impact pressure is big, so it is easy to deformation of the case, in the end will lead to the valve leakage. Three, poor quality of valve repair, lead to gate valve leakage, some workers at the time of repair valve, without the ring sealing surface is clean, the existence of impurities affect the operation of the valve, the longer it will scratch sealing surface, thus leading to the valve leakage. Four wedge ring, medium corrosion lead to gate valve leakage, the valve to run for a long time, under the influence of medium, the ring is susceptible to corrosion, corrosion, sealing ring is damaged, so valve leakage. Five, the body has a defect, the body if there is a problem such as porosity, slag inclusion, crack, sand holes, then the gate valve in use process is prone to leakage. Anyhow, carbon steel gate valve leakage is a common problem, if there is a leak, would endanger the safety of the equipment and personnel, so want to timely find out the reason and solve problems.
