Carbon steel gate valve 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 valve 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 valve 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 Industrial Valves leakage. Four wedge ring, medium corrosion lead to gate Industrial Valves 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 Industrial Valves 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. Nowadays, stainless steel gate valve has been widely used in industrial field, it is a very good stainless steel product, compared with those of other material advantage particularly prominent, especially on the applicability of the medium, the superiority of stainless steel gate is other materials incomparable. Of course in addition to this, advantage is mainly embodied in the following several aspects. A, stainless steel gate valves with various models of various standards, so that be able to choose the right, according to the different demand that whatever works to be able to play a good role. Second, safe and reliable stainless steel gate, is more convenient and flexible operation, also do not need too much maintenance, because the probability of failure is low. Third, the disc knife function, to eliminate clutter is brake off the medium has great benefits. Four, the structure of disc set reasonable, length is shorter, so at the time of installation, disassembly is very convenient. Five, stainless steel gate valves use is very convenient, it adopt wedge flexible disc structure, using the friction is relatively small, in the process of opening and closing is very flexible and convenient. Stainless steel gate valve, therefore, the advantage is very outstanding, but flange gate devices on the market a lot of, the product of manufacturer of different quality is different, some small manufacturers in order to save cost and choose inferior materials, the production process does not pass, so that the production of equipment in use process will appear many problems, so everyone choose stainless steel gate, where must to large producers, such problems encountered in the use process also can contact manufacturer to solve.
If you are looking for an effective and safe way to take care of cast iron valve, then flanged gate valve os&y gate valve are the best bet.
