Chapter 127 Inspiration from the Pressure Cooker

When Li Jiajun rushed into the cafeteria, the Fat Master Chef in charge of cooking was holding a soup ladle, preparing to reduce the sauce for the stew in the pot.

"Sss-sss-sss—"

Driven by the steam, the pressure-limiting valve of the pressure cooker spun and danced frantically, ejecting columns of white steam and making a rapid, rhythmic sound.

Just as the Fat Master Chef was about to turn off the heat, he felt a gust of wind blow past him.

He turned his head and saw his factory director squatting by the stove, eyes wide as copper bells, staring fixedly at the rotating pressure-limiting valve, his face almost pressed against it.

"D...Director?"

The Fat Master Chef's hand shook in fright, and the ladle almost fell into the pot. "Are... are you starving? The meat isn't even tender yet..."

Li Jiajun completely ignored him.

At this moment, in his eyes, that little iron cap constantly spewing gas was no longer a mere kitchen accessory.

It was a dancer of pressure.

It was a tamer of energy.

"Better to divert than to block... better to divert than to block..."

Li Jiajun muttered to himself, his gaze gradually losing focus, and he fell into a mysterious state of epiphany.

"If the pressure is low, let it leak slowly."

"If the pressure is high, let it spray out."

"The key is to control it... to make it obedient, to make it spray out along the route and at the speed I specify..."

Ding!

[You have observed the working principle of the pressure cooker's pressure-limiting valve, combined it with fluid mechanics and precision valve control theory, and gained insight into the mystery of progressive pressure relief! You have achieved an epiphany regarding the complete process of "Three-Stage Progressive Pressure Relief Intelligent Valve Technology"!]

Boom!

Countless complex mechanical structure diagrams and fluid mechanics formulas instantly filled Li Jiajun's mind.

The problem that had originally troubled him, "how to prevent the canister from exploding," was solved.

"Hahahaha! I've got it! I've truly got it!"

Li Jiajun stood up abruptly, scaring the Fat Master Chef so much that he sat down on the floor with a thud.

"Big Hammer! Back to the office! Start the stream! I need to draw!"

Li Jiajun swept out of the cafeteria like a gust of wind, leaving the Fat Master Chef staring blankly at the still-spewing pressure cooker, speechless.

'Did the factory director... go crazy from smelting steel? He can get that happy just looking at a pressure cooker?'

...

A few minutes later, in the factory director's office.

Li Jiajun stood in front of the whiteboard, the marker in his hand moving like flying.

The camera in the livestream recorded this scene faithfully.

Above the canister body, which was full of hexagonal honeycomb structures, Li Jiajun drew another valve structure diagram that was extremely complex and precise to a maddening degree.

It didn't look like a valve for gas canisters that cost a few hundred yuan at all.

The complex flow channel design and the precision spring components looked like the core parts of some precision instrument.

"Hoo..."

After finishing the last stroke, Li Jiajun turned around, wiped the sweat from his forehead, and a gentle smile like a father looking at his newborn child appeared on his face.

"family! This is what I want to grandly introduce—the core safety guarantee of jia an no. 1!"

He held a pointer, pointed at the valve, and explained seriously:

"Everyone knows, why do gas canisters explode? Because the internal pressure is too high, or external high temperatures cause the gas to expand, eventually bursting the canister."

"However! With my Three-Stage Progressive Pressure Relief Intelligent Valve, an explosion? That is impossible!"

He held up three fingers, his tone passionate:

"I designed three lines of defense for it!"

"The first stage of pressure relief! When the pressure inside the canister slightly exceeds the limit, the micro-hole valve automatically opens, like a pressure cooker, slowly venting gas. At this time, it is gentle."

"The second stage of pressure relief! When encountering high temperatures from a fire, and the pressure rises sharply, the shape-memory alloy spring will instantly pop open, increasing the exhaust volume to rapidly reduce internal pressure. At this time, it is decisive."

Speaking of this, Li Jiajun paused, his eyes becoming fanatical, pointing to the thickest channel in the center of the valve:

"The most critical part is this third stage!"

"If an extreme situation is encountered, such as the canister being violently hit by a heavy object, or if the internal pressure instantly breaks through the critical value!"

"This main valve will instantly open completely! Utilizing a special Laval nozzle structure, it will eject the high-pressure gas from inside in an extremely stable, extremely controllable, and directional manner!"

He mimicked the action of jetting while saying excitedly:

"In this way, although the gas is gone, the canister will definitely not explode! It will only safely... er, although the commotion might be a bit loud, it is absolutely safe!"

"This is what you call—nipping a disaster in the bud! This is what you call absolute safety!"

After Li Jiajun finished speaking, he put his hands on his hips and looked at the camera with an expression begging for praise.

He felt that his design was simply perfect.

It not only solved the safety hazards but also embodied industrial aesthetics.

However, there was no "666" spam in the livestream as he had expected.

On the contrary, the comment section fell into a strange silence.

After several seconds, a few scattered comments drifted by.

"Um... Streamer, what did you just say?"

"Laval nozzle structure?"

"Instant? Stable? Controllable? Directional jetting?"

Li Jiajun looked at these comments, frowned, and unconsciously started his voice-over rant mode, muttering to the air:

"These people... did they not understand? I explained it so simply. Do they really have to make me say it more bluntly? It just means letting the gas spray out instead of letting it stay inside and explode. They don't even understand such a simple physical principle; where did their nine-year compulsory education go..."

Just as he was ranting, a long comment with a trembling tone slowly drifted across the screen, breaking the silence of the livestream:

"Streamer... I work in aerospace propulsion. The third stage of pressure relief you described just now, the stable, controllable, and directional ejection process..."

"Are you sure this is not a rocket engine nozzle?"

"If you replace the gas inside with solid fuel... after this thing is ignited, wouldn't it just take off directly?"

Once this comment appeared, the livestream instantly exploded.

"Holy crap! The person above found the truth!"

"I knew it looked familiar! What the hell kind of pressure relief valve! This is clearly a thruster!"

"Good heavens! A canister with honeycomb armor, paired with a valve with a Laval nozzle... Main Streamer, are you still saying you didn't build a missile?"

"gas canisters: I originally just wanted to cook quietly, but you insisted on making me go to the sky."

Li Jiajun looked at the screen full of "rocket," "take off," and "missile," and only felt a headache.

"Rumors! This is a rumor!"

He slammed the whiteboard in exasperation. "What kind of rocket engine? This is for safety! For pressure relief! Can't you guys have healthier thoughts? Can't you stop seeing everything as a weapon?"

"Besides, whose rocket is built with gas canisters? Can that fly? Can it fly in a straight line?"

He felt that this generation of Netizens was simply unreasonable.

To prove his innocence, and to prove that this design was a purely civilian product, Li Jiajun decided to put it into production immediately.

"I'm not wasting any more breath on you guys! Big Hammer! Prepare the materials!"

"We are going to build jia an no. 1 right now! When the time comes, I will personally demonstrate to them what safe pressure relief is!"

He angrily turned off the livestream.

But what he didn't know was that just during the livestream, in a corner thousands of miles away, a pair of eyes was staring fixedly at the valve blueprint he had drawn on the whiteboard.

The owner of those eyes, upon seeing the words "Laval nozzle," felt their breathing become rapid, as if they too had found inspiration.
