In the next week or two, Fang Bai went to T City again for the sixth TV purchase.

Refurbished second-hand TVs are selling in full swing, and more and more Wencheng people know about his stall.

His personal wealth has also accumulated to 700,000 yuan.

The number of contacts is still 7, and it is difficult to grow.

Now, Fang Bai is very much looking forward to what new changes will occur when his wealth grows to one million, and the middle finger gold finger can be upgraded again.

There is still a wealth of 300,000 yuan, and it will take a month at most!

Earning 300,000 yuan a month, he beat most of the large-scale factories in Wencheng, including Hengli Company, Boehly Company and Nanjiang Company, and the combined profits of the three companies are not as much as he earns.

If Fang Bai spends all his energy on refurbishing TV, it is okay to earn tens of millions a year, but it will be difficult to do more, and it is difficult to do it without relying on him to choose TV.

Therefore, after a certain scale, selling TV is still not comparable to these valve factories.

During this time, Fang Bai was reading books in the school in the afternoon, and his advertising words were widely circulated by students in the school, and even many students knew that this line and recording were made by Fang Bai, and more people went to his booth to listen.

In these years, this kind of novelty is still relatively rare, listening to it, funny, as long as someone promotes it, it will spread quickly.

Just like the words of Huang Xing's nephew in later generations, everyone in the country knows it.

It didn't take long for Zhan Feng to know about these things, and he specially talked to him: "Fang Bai, the booth that sells TV belongs to your family?" ”

"Teacher Zhan, I thought there was something, that's it, there's no fuss." Fang Bai really didn't want to talk about it.

"Anyway, I'm quite surprised, I remember that someone said that he knew the stall owner, or from the same village, hehe, how can you call it acquaintance!" Zhan Feng was a little strange that Fang Bai didn't tell her honestly and hid too many things.

I remember that at the beginning, the teacher in her office was talking about buying a color TV, and Fang Bai overheard it and helped them discount it.

Colleague 9% off, she 20% off!

Ouch, it made her cry of gratitude, and she was moved.

I'm embarrassed!

There are also many teachers who owe her favors and send her fruits, and they have all the good things to say.

It turns out that I helped my own TV sales!

No wonder it's so positive!

Selling himself and helping others count the money, this feeling of being a fool, Zhan Feng experienced it for the first time.

Of course, she did save a lot of money, but she was angry about Fang Bai deliberately hiding that his family sold TV.

This student is so clever that he always thought he was an honest person.

Before, when she listened to the recorded advertising words, she could tell that it was recorded by Fang Bai, but she didn't expect it to be his stall, and the student misled herself from the beginning.

"Hehe, Teacher Zhan, this seems to be fine." Fang Bai saw her gritting her teeth, but it didn't look like she was angry, she probably felt that she was being played, and she was thinking about it.

Hey, women really can't be messed with casually.

"Hehe, don't pretend to be confused for me, I'll make a lot of money by selling good things, and I'll have a monthly exam in a while, give me the first test."

Fang Bai smiled: "That's okay, the penultimate meaning." ”

Zhan Feng's eyes widened, and he emphasized sternly word by word: "It's the first in the grade!"

If you deliberately take the first place in the exam, then you go back to class and cancel the long vacation. ”

"How is it possible, which of those top students is muddy."

"I think you have the strength, you have to believe in yourself."

"Teacher Zhan, if you say that, my self-confidence can be inflated!

To be honest, in fact, I can take the Qingbei test, but for fear of scaring the school leaders, I just keep a low profile, who knows that the low-key is too much, and the test will be smashed. ”

"It's okay to give you a sweet date, you have to know how to be humble, don't talk about Qingbei, even if it is a key university at the next level, the school can treat you as an ancestor, really, go back to the classroom and read well."

"Okay, obey."

Fang Bai saluted solemnly, then turned to leave.

Zhan Feng looked at Fang Bai's back as he left, and couldn't help but smile, this student, sometimes thieves are pleasing and make people angry.

Also, I misunderstood that he was a medical finger when he left school?

Is this true or false, and is it necessary to take time off so often?

Forget it, don't dwell on this, Fang Bai's grades on a long vacation are getting better, so let him continue to ask.

Fang Bai, who left the teacher's office, breathed a sigh of relief, the psychological age of dozens of years old, sometimes pretending to be a student is very tired.

However, this is the leisurely life of a reborn person, and if you keep your face tight all day long, like an old man, how can you be happy?

On December 20, Fang Bai went to Nanjiang Company to settle the processing fee.

He first wanted to visit Huang Xing, seeing that he was not in the office, it was estimated that he was studying products in the workshop again.

When I came to the workshop, I turned around and saw Huang Xing wearing gloves to test the valve in the pressure test workshop, and there were three employees around.

"Mr. Huang, there is a new product coming out, admire."

Hearing the familiar voice, Huang Xing stood up and turned his head, saw that it was Fang Bai, beckoned to him, and replied with a smile: "Eh, yes, but there are a lot of problems, or leaks, it's too much of a toss, I don't have a clue." ”

A new product, the 6-inch 600-pound butterfly valve, is being worked on, the pressure is higher, and there are more problems.

The butterfly valve is much the same, even if it is copied from foreigners, there are still many problems when it is made, and it is not easy to find the cause of the problem.

He wished that someone would help him solve the problem now, seeing that it was Fang Bai, he felt that he had helped him once, and he must be very familiar with the butterfly valve, otherwise it would be impossible to see that there was a problem with the sealing groove, it was not something that could be blinded casually.

This is the same as a car engine failure, if you are not familiar with the car, how can you find out that it is an engine failure at a glance.

Some people can tell what the problem is just by listening to the sound of the engine.

"Fang is always a butterfly valve expert, can you help me analyze it?"

Huang Xing didn't expect Fang Bai to find out the cause of the problem, but the whole company knew about butterfly valves, except for him, there were only two technicians next to him, and the other one was a worker, let alone a worker.

It is impossible for him to consult the technical experts of other manufacturers, which involves other people's patented technology, but Fang Bai is different, he is a salesman and has cooperation with his own company.

After the product is made, he has no problem processing it if he wants.

Fang Bai glanced at a few butterfly valves on the ground and asked: "Experts can't talk about it, just have some understanding, Mr. Huang, you are an expert, but as a person in the bureau, you just happened to encounter some inspirational problems, which cannot be solved purely by technology."

Or is it a batch problem? Do you know why? ”

Huang Xing was praised and laughed, and said: "It's a batch problem, the same as the problem, I now know that it is leaking from the valve disc, I think it may be a problem with the sealing ring, or the adhesion force is not enough." ”

If the working pressure is 600 pounds, the pressure test requirement is 1.5 times, that is, 900 pounds, and the time lasts generally within three minutes.

After the valve and pipe are connected, they are immersed in water, and the pipe is ventilated, and if you see bubbles coming out of the valve, there must be a leak.

It's just that I can't see what exactly is missing.

Fang Bai squatted down to check, first did not use the gold finger test, and analyzed it with his own experience.

The technician next to him handed him a new pair of gloves, and Fang Bai first tried to close the gate after putting on the gloves.

After a while, he asked, "Is there a flashlight?" ”

"Yes, in the office, I'll get it." After the young technician finished speaking, he hurried back to the office.

Fang Bai stood up and thought about it first, Huang Xing looked at his thinking appearance, and asked curiously, "Can you see anything?" ”

"Use the elimination method, the same elimination, take a flashlight to check first."

"Hmm."

Huang Xing probably knew what he was doing with the flashlight, after the valve was closed, it shone from one side, and if there was light coming out from the other side, it must have leaked.

Of course, their direct pressure test is more accurate, and there may be leaks where there is no light.

It's just that now these butterfly valves have been removed from the pressure tester, and it is more convenient to illuminate them with a flashlight.

Moreover, even if there is a leak, I don't know which part is leaking, after all, the pressure is tested only after the valve is connected to the pipeline, and the leakage bubble alone cannot see the location of the leak, so it can only be estimated.

After a while, the technician came with a flashlight and handed it to Fang Bai.

Fang Bai turned on the flashlight switch, a beam of strong light shone out, he aimed at the valve plate to check, and everyone helped to hold the butterfly valve.

"There's light on the inner passage, it's so obvious."

Everyone also saw that Huang Xing also said "Huh" and said: "Yes, it's so obvious, no wonder it's leaking badly, there are too many bubbles during the pressure test, and I thought it was a comprehensive leak, so I can't see it." ”

Fang Bai then used the gold finger LV2 to analyze, and found that the position of the valve disc and the valve stem was red, although there was no prompt, but he quickly figured out that the gap was too large.

"Mr. Huang, it is very likely that the gap between the valve disc and the valve stem is too large, which causes the valve disc to sag or the contact is not good, try to adjust the cavity gap between the valve disc and the valve stem."

"Is the disc sagging?

Why didn't we expect that we kept changing the sealing ring, and we didn't find the right direction. After listening to Fang Bai's words, Huang Xing felt very reasonable after thinking about it for a while, and said to the two technicians, "Adjust it according to Mr. Fang's meaning and then try the leak." ”

After explaining, he remembered that Fang Bai must have something to do when he came over this time, and when he asked, it turned out that he was asking for money, said sorry, and took him back to the office.

The two technicians and workers who stayed behind looked at each other and couldn't help but praise: "Mr. Fang is really amazing, you can see the problem at a glance, and it was the same last time." ”

"Well, golden-eyed, we're looking for problems, and we don't know how to go back to the office and take a flashlight to shine it, stupid."

"If Mr. Fang is engaged in research and development, it will be amazing, but it's a pity to run the business."

"Running business makes a lot of money, but what you said is right, he is so young, this kind of person running business is purely a waste of talent, and the country also has a lot of such talents, but they are forced to go abroad if they can't play their role."

Everyone sighed, feeling that some units were just very grassy, so that real talents were lost in vain.

And those villains can be on top.
