调节阀在小开度下工作的危害及解决对策

The Valve in the Small Opening Work Hazards and Countermeasures

生产过程中有时会碰到调节阀出现在小开度(比如控制在5%以下)下工作的现象,这常常是由于实际工艺参数与设计的参数不相符的缘故,调节阀如果经常工作在小开度下,不仅影响阀门的使用寿命,也给生产的自动化控制带来很大的影响,下面结合开祥精细化工的实际情况,共同探讨一下调节阀在使用过程当中出现的这种情况及其解决方法。

In the production process will sometimes encounter a small opening in the valve occurs（such as control in the following 5%） under the work of the phenomenon, it is often because of the actual process parameters and design parameters are not consistent with the reason, if the valve often work in a small opening, not only affects the service life of the valve, but also to the automation of production control of great influence, combined with our actual situation of the open auspicious fine chemical industry, and we discuss the valve appears in the use process and their solutions.
