Laoshan County.

The Kyushu Institute of Physics in Dakadai has undergone a radical change.

32 people, and still 32 people.

But he was no longer the cowardly teenager. After the steam engine incident, it seemed that overnight, everyone grew.

After getting drunk that night, an invisible burden seemed to appear on everyone's shoulders, and everyone's shoulders seemed to provoke the fate of the family and the country.

No one slackened, but worked harder. I have become more motivated by this research.

"Now, after this period of discussion, we have a definite result."

Li Zhen held half a pencil in his ear, pointed to the drawings hanging on the blackboard and said: "Everyone's divergent thinking is really very keen, we are overheated in the cylinder block, and the short battery life of the steam engine is difficult, and Mingxue has put forward a breakthrough suggestion." Next, let's talk about the improvement of the third-generation steam engine. ”

Ruan Mingxue stood up and looked at the door from time to time when people stopped to watch and admire, and the whole person was full of unprecedented confidence:

"I was awakened when I went to bed last night, and our current second-generation steam engine still has drawbacks, such as: manual decompression, overheating of the cylinder block, steam loss and other problems. So why don't we put a condensation spool valve on the cylinder? ”

Fang Hanxian asked: "What is a condensing spool valve?" ”

"I don't know if you have ever noticed such a daily phenomenon. That is, when we boil a pot of water to eat, when the water boils the noodles, the water will boil and constantly foam. Cover the pot and the foam will always overflow. If you don't cover the pot, it will take longer to cook the noodles. ”

Liu Jinghong nodded: "Yes." In this way, when the noodles are cooked, the flour will interact with the water. ...... in boiling water"

Ruan Mingxue interrupted: "You listen to me." However, whenever 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 a little cold water is less, but it will cause the temperature in the pot to drop. The boiling water will stop, the foam boiling will disappear, and the full pot of foam will turn into clear water...... Hey? ”

Suddenly, Liu Jinghong was stunned, looked at Li Zhen, who seemed to be smiling, and then at Ruan Mingxue, who was smiling, and exclaimed:

"Could it be that when you say condensation, you are constantly spraying cold water in a boiling boiler to cool it down? As soon as the boiling water of the boiler cools down, the pressure will become smaller on the spot? This...... This will indeed save you the hassle of manual decompression. But, what is a spool valve? ”

Ruan Mingxue spread out the drawings on the blackboard, but saw that the drawings were painted with the appearance of a cylinder. There was a hole in the cylinder, and an oval was drawn on it with a dotted line.

The dotted line represents the valve that is blocking the pores. The dotted line also indicates that the valve is removable.

On the valve, a connecting rod was drawn, and the connecting rod protruded out of the cylinder and was connected to the flywheel.

Nguyen Ming Thanh said: "Spool valve is the principle of using a valve core that blocks the exhaust hole and slides on a sealing surface to produce air flow inlet and outlet opening and closing. The flywheel rotates the first half of the revolution, the piston is ejected, the connecting rod drives the slide valve to close, and the cylinder becomes a closed space. The flywheel rotates the second half of the circle, the piston is reset, the connecting rod drives the slide valve to open, the exhaust hole in the cylinder is opened, and the pressure is discharged. This is the spool valve. With a spool valve, the steam engine is like a 'lung' that can breathe. Not only can it exhale out to generate power, but it can also inhale in. ”

"And what I mean by condensing spool valve is a more efficient valve added to this foundation. Utilize the principle of condensation. When the piston is reset, the valve is opened, and the water tank connected to the valve is sprayed with cold water to reduce the pressure again. Of course, spool valves alone can solve the problem of pressure reduction. But with condensation, the efficiency of that instantaneous depressurization of the steam engine will be greater when the piston is reset. In this way, the steam utilization rate of the steam engine will be higher, and the steam power will be more powerful. ”

The voice fell, and for a long time, there was silence in the field.

Li Zhen stood up, looked at Ruan Mingxue with an affirmative look, and clapped his palms.

'Bang la la-la-la looked excitedly at Ruan Mingxue, who solved the problem of the steam engine by dreaming, and applauded constantly.

The applause was thunderous and enduring.

Ruan Mingxue looked at this scene, his face turned red, and he kept saying that he had won awards with his head down.

Li Zhen stood aside, his whole body was full of Tai, relieved, relieved!

From the very beginning, he understood that his purpose was to lead the country to prosperity and rejuvenation. Rather than allowing yourself to go strong alone.

He doesn't need to prove himself with one technology after another.

He just wants to sow the seeds of scholarship and divergent thinking. He wants to make himself understand and others to understand as well.

He did it, and finally he did.

led the Kyushu Institute of Physics for such a long time, and in the process of solving the working principle of the steam engine, they successfully restored the steam engine.

During this time, everyone learned too much knowledge that they simply couldn't learn in school. Laws of conservation of energy, vapour, thermodynamics, mechanics.

Today, Ruan Mingxue, who was the first to have divergent thinking, put forward a leap forward to improve it. It's an opinion that even Li Zhen didn't expect for the time being - spool valve! Condensation!

Two points of view made Li Zhen excited. Really excited, excited from the heart. He seemed to see the future in a land full of creative people. And not a bunch of people who follow the script......

Li Zhen knocked on the blackboard: "The theory of spool valve and condensation proposed by Mingxue. Verify as soon as possible. Immediately make two steam engines of the same power and the same size. A steam engine uses a spool valve, and a steam engine uses a condensation spool valve. We need to verify whether the condensate spool valve is more efficient or the pure spool valve is more efficient. This needs to be verified. ”

"Good!"

A group of people dispersed excitedly, found Master Wang, redrew the drawings, and immediately began to prepare for the test of the third-generation steam engine.

And Li Zhen took Qi stunned and walked out of the Kyushu Institute of Physics.

There were a lot of people standing at the door, not the villagers of Dafengtai. The villagers of Dafengtai stood from a long distance and watched, because they liked to talk and were afraid that the sound of discussion would disturb them and others, so they always watched from a distance.

And these people are brightly dressed, well-dressed, and look extremely cultivated and wealthy. In the distance behind him, there are many fierce men who should be bodyguards.

Li Zhen stood at the door and said with a smile: "Is there something wrong with you?" ”
