Industrial use of the American standard for the safety valve is very frequent use of such safety valve has the advantages of cost-effective, wide range of effects, security and good, and in a large number, long-term use of the process, the safety valve will inevitably appear Some large and small faults, let us take a look at these failures should be how to deal with it? Such safety valves often occur above the fault can often be divided into two categories, the first type of common fault is the safety valve leakage, in the event of leakage problems, we need to immediately stop the entire machine operation, while effectively safety valve The cause of the leak to find out, the appropriate solution. In general there is leakage of gas, which are usually American standard safety valve inside the poor contact with some parts of the base, the gap in the middle, it may be some of the impurities in the production process went to the safety valve, resulting in obstacles and gaps , So as long as the cause of the problem is found, it is generally easily solved by the staff member. Another problem is that the safety valve does not work, that is to say when the valve pressure, the safety valve does not automatically open, this situation usually has more conditions, for example, some may be the life of the safety valve over Long, spool and seat may be due to problems such as oil adhesion together, so I can not work. It is also possible to set the above problems, the value of the spring pressure inside the American Standard safety valve is adjusted too large, making it the relative increase of the sensing threshold, it can not be normal induction, the best question in this regard, please professional maintenance personnel to To detect and find, targeted repair, make it back to normal.
