Scholars in the courtyard

Looking at the components in front of him, Yang Xiaotao understood that this was a simulation before the formal experiment.

Data obtained through simulation, whether correct or incorrect, is equally valuable.

The structure of this shell is also constantly simulating possible situations during exploration.

Take all these situations into consideration to eliminate hidden dangers and obtain the maximum success rate.

After thinking about this, Yang Xiaotao began to calculate in his mind.

If the precision meets the requirements this time, then there is no need to say more and the task will be completed directly.

But if the requirements are not met, then continue to improve the precision? When is the end?

Manpower will eventually be exhausted.

Here, we need to have firm faith, and even more so, we need to believe in science.

After all, what is hidden here is the magic of science. If you want to release it, you must not pay attention to science.

But where is the other way?

It is obviously not possible to directly pour a whole steel plate, so it can only be manufactured.

Yang Xiaotao held his head and drew aimlessly on the paper with the pencil in his hand. From time to time he raised his head and looked out the window. The sun was so dazzling that he subconsciously ducked aside.

"Why did it break and crack?"

His head was hidden away from the sun.

Then he looked at the scorching sun, and there was a dazzling light in front of his eyes. There were still strange stains in his eyes.

"This sun is the source of light. At the moment of explosion, wasn't it just a ball?"

Light travels in a straight line.

Straight.

It bursts out from a point or mass and then shoots out in all directions.

That.

"etc."

Yang Xiaotao suddenly found a glimmer of inspiration. Although he didn't know if it was right, but if he didn't try it, who would know if it was right?

"The joint broke because the pressure inside was too great."

"Pressure, where does the pressure come from?"

"Why is there pressure?"

"Yes, it is the pressure generated by the explosion reaction."

Questions popped into my head one by one, and then they were quickly written down on paper.

Pressure in physics refers to the vertical force that occurs on the contact surfaces of two objects.

Yang Xiaotao drew many lines on the vertical force.

So what are the factors that affect stress?

Afterwards, Yang Xiaotao solemnly wrote down a formula.

A very simple pressure formula from a past life physics class.

F=PS

"Then, the pressure on the shell must be kept constant, and when the pressure gradually increases, the stress area can only be reduced."

"The question is, how to reduce the stress-bearing area?"

Yang Xiaotao tilted his head, thinking about the increasing pressure inside the container.

What structure should be used to keep the pressure area of ​​the interface to a minimum?

And pressure comes from everywhere, and the effect of that force is chaotic. Why not use internal pressure to make the joint tighter?

The two directions made Yang Xiaotao fall into deep thought.

Looking at the drawings beside him, Yang Xiaotao suddenly froze on the connection. It was simply processing two pieces of steel into a gear shape, and then meshing them together to fix them.

Including the improved accuracy now, it means improving the accuracy of the two gears and reducing the gap.

Yang Xiaotao looked at the requirements for processing the end of the steel sheet on the design drawing. Suddenly Yang Xiaotao made a strong stroke at the interface and pulled up the contact surface. It looked like an extra semicircle on the contact surface. No, it should be a pipe cone.

The protruding piece is hidden inside, so that no matter where the internal pressure comes from, only the line in frontal contact bears the strongest pressure.

Moreover, in addition to this line, when pressure from other directions acts on the cone, it will force the connection to become tighter.

Just do what comes to mind.

Yang Xiaotao found another piece of paper and modified the original workpiece drawing.

Half an hour later, Yang Xiaotao looked at the revised drawings and put down the pencil in his hand.

He felt that this method was worth a try.

After getting up, Yang Xiaotao went to Zhang Laodao's office. Seeing that there was no one in the room, Yang Xiaotao went to the workshop.

Zhang Laodao, who was walking around, originally wanted to see if Yang Xiaotao had finished it and then hand in the task tomorrow.

I tried to see if it would work this time, but I didn’t want to miss Yang Xiaotao’s shadow.

After asking Shen Rong, he heard that he had gone back to study with the drawings, but he was not reassured. He was a ninth-level engineer. Let alone level 9 here, even level 8 was at the bottom. There were a group of senior engineers, and he was a level 9 engineer. What can be seen?

Just as Zhang Dedao was about to go back, he suddenly saw Yang Xiaotao running towards this side.

"You kid, if you don't work, what are you doing?"

"I'm going to do an experiment tomorrow. If you don't want to go, tell me in advance."

Zhang Dedao came up and counted, but Yang Xiaotao ignored him and took out the drawings he drew.

"Team Leader Zhang, I modified this based on this drawing."

"Drawings? Why are you doing this? Those jobs are not enough for you."

As he spoke, Zhang Laodao picked up the drawing, then took the original drawing and compared it carefully.

At first I just looked at it, but after seeing the renderings, especially when Yang Xiaotao put the joints together, it became more intuitive.

"You did it?"

Zhang Laodao was a little surprised, because he also felt that Yang Xiaotao's design seemed more reasonable.

"Well, this is just what I thought. I don't know if it will work yet."

"Leave this here and follow me tomorrow."

"good!"

With Zhang Laodao coming forward, he is better than a newcomer like him.

Moreover, I will meet my parents tomorrow.

Although it is a bit inappropriate, it is indeed a meeting with the parents.

Sijiucheng, steel rolling mill.

Within ten workshops.

Yi Zhonghai is also making improvements to the drawings.

As an eighth-level fitter, he naturally understands drawings.

What's more, the drawings made by the technical department are simple, which is convenient for him to modify.

On the basis of the original pot lid, the edge position should be extended in a circle. As for the thickness, because the length needs to be increased, the thickness can be appropriately reduced. Anyway, it only needs to cover the rubber ring. If it is too thick, it will look unsightly.

In addition, the place where the rubber ring is installed on the pot body needs to be changed to a semi-buried type.

In the workshop, Yi Zhonghai kept writing and drawing. Guo Dabozi and others watched nervously. They did not dare to say anything and allowed Yi Zhonghai to do whatever he wanted.

Qin Huairu leaned on Guo Dapi and looked at Yi Zhonghai, writing quickly.

I am more determined mentally and must let Banggeng study hard and go to school. Even if he cannot reach the height of Yang Xiaotao in the future, he must be a capable person like the first uncle.

When the time comes, I will leave this job to Banggan and enjoy the happiness at home.

Qin Huairu was thinking about it, but she didn't notice anything strange about Guo Da Pai next to her.

At this time, Qin Huairu was not wearing much, and her proud figure was undoubtedly on display. Moreover, the smell of soap on his body was fresh, which made Guo Dapizi involuntarily look at the white snow under his neck and the conspicuous big lantern.

This little widow is delicious.

Guo Dayai stared at Qin Huairu for a while. Qin Huairu on the side finally felt something. However, his body did not dodge. Instead, he moved his shoulders without any trace, making it easier for Guo Dayi to see.

Ahem

Guo Dayao suddenly felt uncomfortable in his throat, "Comrade Qin Huairu, go get some water."

Qin Huairu was stunned for a moment, then responded, "Okay, director."

After speaking, he twisted his butt and walked out.

"By the way, I still have some sugar over there, I'll get it."

Guo Dabozi waited for a while, said to the people around him, and then left the scene.

Everyone didn't take it seriously and continued to watch Yi Zhonghai drawing pictures on the spot.

Guo Dapizi, who left the workshop, looked at Qin Huairu who was slowing down in front of him and followed him with a smile.

The two of them did not go to the office, but walked to a small warehouse.

More than ten minutes later.

When the two came back again, Qin Huairu was holding a thermos bottle and sugar in her hands, with a smile on her face, and the white snow on her neck was a little red.

Guo Dabozi on the side also had a smile on his face, with his hands behind his back, and he kept rubbing them, as if he was reminiscing about the previous touch.

After a while, Yi Zhonghai looked at the drawn sketch, which showed the dimensions and style after the transformation, as well as a series of numbers.

The surrounding assault team members came over to take a look, and Yi Zhonghai explained to them.

Everyone knew their tasks and started to pay New Year greetings.

Guo Dabozi and others made room, and everyone in the workshop who had no tasks looked on.

Yi Zhonghai and his assault team worked hard and finally finished the pressure cooker before leaving get off work.

The freshly baked pressure cooker looks no different from Yang Xiaotao's pressure cooker, but the details can still be seen.

Especially the joint between the pot lid and the pot body. The elongated pot lid wraps the pot body, and the rubber ring inside can be completely covered to ensure that there will be no air leakage.

Secondly, perhaps the pressure valve specifications in the drawings were referred to, but the quality of the pressure valve was ignored.

Yang Xiaotao considered quality at the beginning of the design. Otherwise, if the pressure cannot beat gravity, then the pressure must not rise slowly?

Moreover, Yizhonghai obviously ignored the slideway of the pressure valve.

Yang Xiaotao's slide seems to be closely connected to the pressure valve, but in order to keep the pressure valve sliding, the accuracy is very high. Yi Zhonghai and others did not just make it casually based on experience.

Amid various hidden problems, Yi Zhonghai and others did not know about it. Instead, they felt that solving the problem of the rubber ring would solve the biggest problem.

As everyone knows, ignoring these small problems will turn into big problems.

In the middle of the afternoon, the roar of the machines in the tenth workshop suddenly stopped.

"Director, fortunately, I have fulfilled my duty and done it."

Yi Zhonghai wiped the sweat from his forehead, checked it again, closed the lid of the pot tightly, and said to Guo Dabo who was eager to try.

"Master Yi, well done."

"Well done to everyone."

Guo Dapizi smiled, stepped forward and looked at the pressure cooker, nodding his head.

"Director, let's try it quickly and tell the factory the good news then."

Qin Huairu reminded from the side and handed a jar with sugar to Yi Zhonghai.

Guo Dabozi nodded immediately after hearing this.

In the end, I didn't go to the canteen. I found a stove and put coal in it at the door of the workshop to prepare for the experiment.

"Master Yi, don't worry, if this is successful, you will be responsible for the production of this pressure cooker from now on."

Guo Dabozi promised, while lowering his head and whispering, "I will submit an application to the factory, and let the factory respond to the above and let you go home."

This is what Yi Zhonghai wanted. When he heard Guo Dabozi say this, he put down the enamel jar in his hand and immediately looked grateful.

"Director, thank you very much."

Guo Dabo waved his hand, "Whatever you thank me for, it's all due to your hard work."

"Besides, you were also the victim in that matter, but"

"Forget it, let's not talk about that."

Guo didn't want to say anything more and turned to look at the pressure cooker on the stove.

A group of people gathered around, pointing.

"Do you know how to use it? Otherwise, something will happen if you don't use it."

At this time, Qin Huairu stared at the newly opened pressure cooker again and again.

After seeing the appearance of the people around him and making some mental calculations, he suddenly said, "Director, I have seen how to use this pot. Why don't you let me try it."

But it was Yang Xiaotao who often used a pressure cooker to cook things in the yard. Although Qin Huairu and the others didn't benefit from it, they never left their eyes every time they met.

So she still knows a little about the operation of the pot.

Qin Huairu took the initiative to ask for help, which made Guo Dapai put aside his worries about looking for Secretary Xiaoqiang.

After all, she is the secretary to the factory director, not his employee.

And he also wanted to create a blockbuster. When everything was done, he would tell Yang Youning as a surprise, and then hold the right to manufacture the pressure cooker in his hands.

However, when looking at Qin Huairu, Guo Dayao felt hesitant in his eyes.

If the two of them hadn't had a pleasant discussion just now, given his temperament, he would have rejected it outright.

This matter is not a trivial matter. Although their relationship is developing, they will not mess around with business matters and neglect public affairs for personal reasons.

How could he not know Qin Huairu's working status?

How can a person who works like this all day long do well?

People around him also cast suspicious glances. They knew best what Qin Huairu was capable of in this workshop.

That's a hand that makes ten workpieces and eight scraps. Is it appropriate to leave this kind of thing to her?

Besides, if this pressure cooker is completed, the participants will not be rewarded, but they will definitely be taken care of.

Qin Huairu stepped forward at this time just to grab the credit.

But as Qin Huairu said, she had at least seen how to use it, but no one else in the workshop had even seen it.

For a moment, Guo Dapai was hesitant.
