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 Industrial Valves 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. application scope and application field is very wide, play an important in line isolation, cut-off, throttle, cut off, check, stainless steel gate is one of the most commonly used valve type, to take you simply look at the following. Why choice of choose and buy the stainless steel valve gate Industrial Valves in the choose and buy, in general, when the gate is first selection, this is because the valve performance is good, wide applicable scope, in addition to steam, chemical oil cut-off, to contain the particles are also applicable to the high viscosity fluid, has good wear resistance, durable for a long time. Gate valve, besides there is a certain bearing capacity for low vacuum and vacuum line system applies, if it is a low temperature environment, can choose special stainless steel gate at low temperature. Of course, 'preferred' valve must be in view of the general situation, according to the working environment and the actual demand, can be adjusted to choose cut-off valve, butterfly valve, etc. Gate valve how to selection of various types of stainless steel valves, type selection for most people is a difficult problem. Stainless steel gate valve for steam, oil industry, the low temperature, vacuum, and apply the general piping system, when used for the adjustment of the dielectric fluid control, including particle should choose to contain one or two scavenging hole gate, avoid particle accumulation within the valve. For high temperature and high pressure of small diameter pipeline system and the fluid resistance is not strict, how to choose cut-off valve, and the true fluid medium to high viscosity easy precipitation, including particle cut-off valve is inappropriate. Stainless steel gate of choose and buy of the key is to find a brand, for a long time to do supply gate valve manufacturers experienced, professional strong, can give you a lot of valuable Suggestions.
