    carbon steel gate valve is an industrial valve, widely used in petroleum, chemical, power station and other industriesWith automation, easy operation, long service life and other advantages, but in the process of use because of their own or external factors, carbon steel gate valve will leakSo, what is the cause of the carbon steel gate valve leakage? There are several common reasonscarbon steel gate valvecarbon steel gate valve leakage main reason is five points
    1, wedge sealring ring processing accuracy is low lead to carbon steel gate valve leakage, as long as the choice of large brand of gate valve, then the general quality of spare parts are better, so that there will be no seal ring processing accuracy is low2, production operation conditions unstable lead to leakage in the gate valve, the requirements of the gate valve on the working environment is relatively high, if the pressure and temperature environment is unstable, the magnitude of change is too large, then the sealing ring to bear the impact pressure, so it is easy to deform the situation, in the end lead to valve leakage3, poor valve maintenance quality led to leakage in the valve, some staff in the repair valve, did not clean up the sealing ring sealing surface, the presence of impurities affect the operation of the valve, the long-term will scratch the sealing surface, which will lead to valve leakage4, media corrosion wedge seal ring caused the valve leakage, valve long-term operation, under the influence of the medium, the sealring ring is easy to be corroded, corrosion to a certain extent, the seal ring is damaged, so that the valve leakage5, valve body is defective, if the valve body has air holes, slag, cracks, sand eyes and other problems, then the valve in the process of use is prone to leakagein short, carbon steel valve leakage is a relatively common problem, if there is a leak, it will endanger the safety of equipment and staff, so to find out the cause and solve the problem in a timely manner
