Problems to be paid attention to in the use process of high temperature butterfly valve

With its own unique advantages, high temperature butterfly valve has been widely used, but in the process of use, there are still a lot of problems to be paid attention to. Here we will understand the problems that should be paid attention to in the use process of high temperature butterfly valve.
1, before the use of a comprehensive inspection, check whether the butterfly valve is good, each part is connected to the position, the valve is loose, and so on, to ensure that everything is normal, can be formally used.
2, in the process of using butterfly valve, everyone should pay attention to the state of butterfly valve in time, whether there is excessive loosening, abnormal leakage, or abnormal high temperature, etc. if there is abnormal situation, it should close the valve immediately, find out the cause of the problem and use it after processing, which is also very important. The.
4, to prevent the valve closed, open drain, stagger fault, drain off. The operator should know clearly the function of each valve and the position in the process pipe to prevent misoperation, otherwise it may cause accidents such as running material, mixing, pressing and so on.
5. When the valve is leaked, the leakage position and the cause should be judged first. In general, there are two kinds of leakage and leakage. The external leakage is divided into the leakage of the packing, the valve cover, the leakage of the valve body and the leakage of the sealing surface or lining material. The operator should accurately judge that it should be solved in time and can not be solved. To repair timely treatment.
6, the valve packing gland pressure should not be too tight, the valve stem can flexibly rotate should be pressed too tightly, the stem will increase the friction, increase the operating torque. The work of the valve, generally not just replacing or adding packing, otherwise, caused by leaking medium

3, after the use is finished, we need to do the appropriate cleaning immediately. After the valve is closed, the soft cloth should be used to clean, and some impurities in the valve may be removed, and the lubricating oil is lubricated so that the next use can be better guaranteed.
