In a small town, there is a chemical plant. Although it is not big, it is the source of livelihood for many families in the town.
Li is a senior technician in this factory. He knows every piece of equipment well, especially those manual valves that seem ordinary but are crucial.
A sudden failure, manual valves save the day
One day, the factory received an urgent order and needed a batch of special raw materials. The whole factory entered the stocking state, but a failure occurred at the beginning of production, causing the production line to stagnate. In a critical moment, Master Li quickly closed the electric valve and turned to operate the manual valve. With the roar, the machine started to run again.
The factory director asked Li: "Why do you still keep these manual valves?" Li smiled and said: "These manual valves are my 'loyal partners'. Although simple, they can always come in handy at critical moments. You see, if it weren't for them today, our order would have been ruined."
Since then, the manual valves in the factory have never been neglected. Li not only maintains them, but also tells new employees: "Don't underestimate these manual valves, they are the 'guardians' of our factory."
Although manual valves are not as "high-end" as electric valves and pneumatic valves, they are simple, reliable and flexible, making them indispensable "saviors" at critical moments.
No matter how advanced the technology is, don't forget those obscure but always reliable "old friends". They may be inconspicuous, but they can always give you the most solid support when you need it.
