In the general pressure cooker, the pot body and the lid are connected by buckles, and the contact points are closed with sealing rings, which is simple in structure and easy to use.
Like the one in front of him, the threaded pot lid, Li Fengman used it for the first time, and he had to admire the old blacksmith's head, full of flexibility, creating conditions when there were no conditions, and finding another way.
It's a bit of a hassle, but it's a good idea.
The wisdom of ancient craftsmen cannot be underestimated.
However, whether this threaded structure is so effective and whether it can withstand the high pressure of the gas in the pot still needs Li Fengman to do a specific verification.
Li Fengman was very careful, and after putting the iron pressure cooker on the stove, he didn't stop for long, but walked away quickly, and kept everyone around him away from the stove.
After all, it is the first time to try, no matter how exquisite the old blacksmith's craftsmanship is, it must be precautionary.
A pressure cooker is not an ordinary cooker, and if you really want to fry it, it can really kill people.
"Don't worry, old man, what I made is notoriously strong and durable, it's just to cook some meat, there won't be any problems!
There's no need for us to hide so far. ” Feng Cai saw that Li Fengman was so careful, he didn't even have the courage to stand next to him, and couldn't help but comfort him.
Because they didn't understand it before, they didn't know the specific purpose of the pressure cooker and how to use it, so Feng Cai and the others didn't test it in advance.
I just saw Li Fengman's operation, it's not just like an ordinary iron pot, adding water to cook, but the lid is more secure.
What's the danger of just cooking?
Not only Feng Cai, but also Feng Cai's apprentice, as well as Gen Fu, who was half-paralyzed, also felt that Li Fengman was making a fuss and making a fuss.
Boiling a pot of water, but people have to hide more than ten meters away, is it a little cowardly?
Li Fengman naturally saw the strange looks of several people, but he didn't explain much to them, as long as people came out, no matter what, safety first.
I have to say that the fire used for striking iron is really strong, and after a while, the outlet valve of the pressure cooker has begun to have a sizzling exhaust sound, and the water in the pot is already boiling and accumulating.
The critical moment has arrived.
As the air pressure in the pot continues to rise, the sealing connection between the lid and the pot body, as well as the exhaust pressure control performance, are subjected to real high pressure tests.
Whew!
Whew!
The air flow was rapid, and it was sprayed out of the reserved air outlets, making louder and more urgent noises.
Li Fengman's complexion changed slightly, this is not like the sound that a normal pressure cooker will make, it has only been burning for a long time, and the sound of air flow has been so loud, and it is getting more and more rapid, which shows that the air pressure in the pot is rising sharply, and the pressure limiting valve on the lid of the pot does not control the strong pressure inside.
"Something seems to be wrong, everyone be careful."
Li Fengman couldn't help but remind him, his eyes fixed on the pot body that was rapidly suffocating in the room.
As it turned out, the old blacksmith's thread sealing performance was really good, the air pressure in the pot was rising rapidly, and there was not the slightest gas leakage under the lid.
The problem now lies in the safety setting on the lid of the pot, although the pressure cooker is high, there is a limit, and it is impossible to increase the pressure indefinitely, so that no matter what the material is, it will not be able to withstand the increasing pressure inside.
Feng Cai shook his head disapprovingly and said: "Childe doesn't have to be nervous, it's just that the water is boiling and steaming, the iron pot I made is very strong, not to mention the water vapor, even if you use an axe to smash it, don't want it to be damaged for a while." ” The old blacksmith is so confident.
"I wonder how long this pot will burn?"
The old blacksmith asked Li Fengman: "If Gongzi is afraid of danger, I will ask Xiao Wu to go inside and bring out the pot in a while!"
” Xiao Wu is the little blacksmith who has been staying here to accompany him, and when he heard the old blacksmith's words, he nodded directly without the slightest hesitation.
"No problem, I'll go now!"
While speaking, the young man looked at Li Fengman's gaze with a hint of disdain, and he had already labeled Li Fengman as a pampered and cowardly in his heart, and admired and admired in his heart because of those unique iron designs, and was directly washed away by Li Fengman's timid performance.
Everyone thinks that Li Fengman is worrying about the sky, just ordinary boiling water and boiling things, where is the danger?
Li Fengman shook his head slightly, these ancients didn't know what they were facing at all, a sealed container, infinitely expanding air pressure, once it burst out, the power was about the same as a grenade, if it was close, a small piece of iron would be ejected, and whoever touched it would die.
"Don't worry."
Li Fengman stopped him and said, "This is just the beginning, under normal circumstances, you have to cook it for at least a moment, and then wait." ” It's only been a few minutes, and to let people in when they know that the pressure cooker is out of order is simply a matter of life.
Feng Cai nodded as he said, and raised his hand to stop the little apprentice who was eager to try.
Li Fengman is the customer, so naturally he has to take Li Fengman's meaning as the top, and besides, the old blacksmith is very confident in his craft, let alone boiling for a quarter of an hour, as long as the water in the pot is not dry, there will be no problem even if he cooks for a day.
"Don't stand in the doorway, we'd better all retreat behind the wall."
Li Fengman confessed again, and then he trotted to the edge of the door, using the wall as a cover, feeling safer.
"Li Gongzi, there is really no need for this......"
Feng Cai was about to open his mouth to persuade when the sound of jets in the room suddenly stopped, and he instantly felt that the surroundings were much quieter.
The old blacksmith couldn't help but look back, and his body unconsciously wanted to come to the front to see what was going on.
"What's going on?

Is the fire out or is the water already boiled dry?
The old blacksmith muttered to himself, and one foot had stepped into the door.
"Danger, come back quickly!"
Li Fengman's face changed in fright, and now there is no sound of exhaust, the pressure in the pot will definitely rise sharply, and now when he goes in, he is simply looking for death.
The old blacksmith waved his hand at Li Fengman disappreciably, "It's okay, Li Gongzi can let ...... it" Rumble!!
There was a loud bang that shook the earth, directly overpowering the old blacksmith's voice, the house shook, the ground shook, and their ears were buzzing, and they could not hear a sound.
What Li Fengman said before finally came true, and the iron pot inside was really fried!
The roof was knocked out of a circular hole by the lid of the pot, and the boiler below cracked, sparks flew, and the debris sprayed out was still painful to Feng Cai's old face even if it was ten meters away.
"How so?
It's just boiling water, so how can it be fried?
” The old blacksmith froze in place, muttering to himself.
The little apprentice beside him was already frightened, and his legs were weak and he sat on the ground.
Genfu was startled, and his hemiplegia seemed to have become more serious.
No one thought that that pressure cooker would really fry!
If Li Fengman hadn't insisted on standing outside the door just now, the three of them might have been torn apart just like that boiler, right?
