Laoshan County.
The Kyushu Institute of Physics in Dafengtai has undergone earth-shaking changes.
32 people, still 32 people.
But he is no longer that cowardly young man. After the steam engine incident, everyone seemed to grow up overnight.
After getting drunk that night, an invisible burden seemed to appear on everyone's shoulders, and the fate of the country's prosperity seemed to be on everyone's shoulders.
No one slacked off, but worked harder. I have become more motivated for this scientific research.
"Now, after this period of discussion, we have reached a definite result."
Li Zhen held a half-pencil in his ear, pointed at the drawings hanging on the blackboard and said: "Everyone's divergent thinking is really sharp. We overheated the cylinder and the steam engine had short battery life. Mingxue proposed a breakthrough." Suggestion. Next, let the famous scholars talk about the improvements of the third generation steam engine."
Ruan Mingxue stood up and looked outside the door. People stopped to watch and admire him from time to time. He was filled with unprecedented confidence:
"I suddenly had an inspiration while sleeping last night. Our current second-generation steam engines still have shortcomings, such as manual pressure reduction, cylinder overheating, loss of steam power, etc. So why don't we set a condensation slide valve on the cylinder? "
Fang Hanxian asked: "What is a condensation slide valve?"
"I don't know if you have ever noticed such a daily phenomenon. When we boil a pot of water and eat it, the water will boil and foam will appear constantly. When the pot is covered, the foam will always go out. It will overflow. If you don’t cover the pot, the cooking time will be longer.”
Liu Jinghong nodded: "Yes. That's right. When cooking noodles, the flour will interact with the water. In the boiling water state..."
Ruan Mingxue interrupted: "Listen to me. But every time the hot water in the pot boils and overflows, we only need to add a little cold water to the pot. Will the boiling phenomenon disappear immediately?"
Liu Jinghong nodded: "That's right. Because although a little cold water is small, it will cause the temperature in the pot to drop. The boiling water will stop, the bubble boiling phenomenon will disappear, and the pot full of foam will turn into clear water... Huh?"
Suddenly, Liu Jinghong was stunned. He glanced at Li Zhen, who was smiling but not smiling, and then at Ruan Mingxue, who was smiling, and exclaimed:
"Could it be that the condensation you are talking about means continuously spraying cold water to cool down the boiling boiler? As long as the boiling water in the boiler cools down, the pressure will decrease immediately? This... This will indeed save the time. The trouble with manual pressure relief. But, what is a spool valve?"
Ruan Mingxue spread out the drawing on the blackboard, only to see that what was drawn on the drawing was the shape of a cylinder. There is a hole in the cylinder, and an oval is drawn with a dotted line on the hole.
The dotted line represents the valve that blocks the stomata. The dotted line also means that the valve is removable.
And there is a connecting rod drawn on the valve. The connecting rod sticks out of the cylinder and is connected to the flywheel.
Ruan Mingxue said: "The slide valve uses the valve core that blocks the exhaust hole to slide on a sealing surface to produce the principle of opening and closing the air flow inlet and outlet. The flywheel rotates for the first half circle, the piston ejects, and the connecting rod drives the slide valve to close , the cylinder becomes a closed space. After the flywheel rotates for half a turn, the piston resets, the connecting rod drives the slide valve to open, the exhaust hole in the cylinder opens, and the pressure is discharged. This is the slide valve. With the slide valve, the steam engine is like 'Lungs', it can breathe. Not only can it exhale out to generate power, it can also inhale inward."
"The condensation slide valve I am talking about is a more efficient valve added on this basis. It uses the condensation principle. When the piston is reset, the valve opens, and the water tank connected outside the valve sprays cold water in to reduce the pressure again. Of course. , relying only on the slide valve can also solve the problem of pressure reduction. But with condensation, when the steam engine resets the piston, the instantaneous pressure reduction efficiency will be greater. In this way, the steam utilization rate of the steam engine will be higher, and the steam power It will also be stronger.”
After the words fell, there was silence in the place for a long time.
Li Zhen stood up, looked at Ruan Mingxue with an affirmative look, and clapped his hands.
'Wow!' Everyone stood up. He looked excitedly at Ruan Mingxue, who solved the steam engine problem through his dreams, and kept applauding.
'Wow, wow, wow', the applause was like thunder and lasted for a long time.
Ruan Mingxue looked at this scene, his face turned red, he lowered his head and kept talking about praise and praise.
Li Zhen stood aside, his whole body was full of peace, happy, happy!
He understood from the beginning that his purpose was to lead the country towards prosperity and rejuvenation. Instead of letting yourself become stronger alone.
He does not need to prove himself with each technological product.
He just wants to spread the seeds of academics and divergent thinking. He wants to let others understand while he himself understands.
He did it, finally did it.
After leading the Kyushu Institute of Physics for such a long time, they successfully restored the steam engine in the process of solving the working principle of the steam engine.
During this period, everyone learned too much knowledge that could not be learned in school. Law of conservation of energy, steam science, thermodynamics, mechanics.
Today, Ruan Mingxue, who was the first to show divergent thinking, has put forward radical improvements. It was an opinion that even Li Zhen had not thought of for the time being - slide valve! Condensation!
These two opinions made Li Zhen excited. Really excited, from the bottom of my heart. He seemed to see a future where this land would be filled with creative people. Rather than a group of people who follow a script...
Li Zhen knocked on the blackboard: "The slide valve theory and condensation theory proposed by Mingxue. Verify it as soon as possible. Immediately create two steam engines with the same power and the same size specifications. One steam engine uses a slide valve, and the other steam engine uses a condensation slide. valve. We need to verify whether a condensing slide valve is more efficient or a pure slide valve is more efficient. That needs to be verified."
"good!"
A group of people dispersed in excitement, found Master Wang, re-drawn the drawings, and immediately began to prepare for the test of the third generation steam engine.
And Li Zhen took Qi Lengzi and walked out of Jiuzhou Institute of Physics.
There were many people standing at the door, not the villagers of Dafengtai. The villagers of Dafengtai stood watching from a distance. Because they liked to discuss and were afraid that the sound of discussion would disturb them and others, they always watched from a distance.
And these people are brightly dressed and well-groomed. They look extremely well-educated and wealthy. In the distance behind him, there are many tough men, who should be bodyguards.
Li Zhen stood at the door and said with a smile: "Is everything okay, everyone?"
