1.jpg My story with control valves -------- The master said, “The red control valve is a pneumatic open valve, while the black control valve is a pneumatic close valve.” ”Pointing at some control valves, he guided some newly enrolled college students in getting familiar with the process flow on site. And my mind instantly returned to over twenty years ago, when I first started working at the factory. Scenes of the master taking me to learn various types of knowledge related to refining and chemical processing. “What do you think these towers and pipes look like? ”The master always wore his distinctive smile and asked me cheerfully. “Aren’t these just towers and equipment pipelines? ”I scratched my head and said foolishly to the master, “What else could they be?” ”https://timgsa.baidu.com/timg?image&quality=80&size=b9999_10000&sec=1504923645&di=b26e1fcbda30304a9f506ab557e5ecba&imgtype=jpg&er=1&src=http%3A%2F%2Fcenter.cnpc.com.cn%2Fpic%2F0%2F00%2F05%2F21%2F52156_750990.jpg The technician, looking at the various devices inside the unit, said to me with pride, \"If we compare a set of equipment to a ‘person’, then the DCS system is the nervous system of that ‘person’.\" ； Pipes and equipment are the ‘organs’ of ‘people’ ； The flowing medium is the blood of ‘humans’, the control valves are the limbs of ‘humans’, and then what is the brain of ‘humans’? ”“Could it be us operators? ”With doubts in mind, I mustered up the courage to answer in a hushed voice. “That’s right, don’t underestimate yourself – you are the brain of the device; its proper functioning depends entirely on whether your brain works well! Keep it up, I have faith in you! ”The master patted my shoulder and spoke to me earnestly! I! ? ……Brain? …… There's a bit of anxiety in my heart, along with even more competitiveness! https://timgsa.baidu.com/timg?image&quality=80&size=b9999_10000&sec=1504329167597&di=9cbd0b7f9ef4b8a706ebf3a6fdcb801f&imgtype=0&src=http%3A%2F%2Fimg1.cache.netease.com%2Fcatchpic%2FC%2FC1%2FC1577A82B42E9F5CBD9FDFD6B7786891.jpg Note: This article is part of the “My Story with Control Valves” writing contest; the image comes from the Internet, while the text is original to me.
