How a gas regulator works
HTML-код
- Опубликовано: 4 май 2024
- In this video we will look at the mechanism inside a pressure regulator for liquefied petroleum gases, such as natural gas and propane.
Pressure regulators are critical components used with gas appliances. They reduce the inlet pressure from high-pressure sources like tanks or pipelines to the desired lower outlet pressure suitable for applications such as heating and cooking.
They serve as essential safety devices by maintaining a steady outlet pressure to the appliance, regardless of fluctuations in the inlet pressure, and automatically cut off the gas flow when it reaches a certain pressure, preventing pressure spikes.

Holy crap. 5 minutes, no stupid sponsors, no bs. And I learned something. This is what RUclips should be. Thank you.
You are welcome 😁
Criminally underrated channel
Absolutely!
Dozens of channel with this style. Overrated if anything
Absolutely agree! He explains stuff in a was that makes so much sense to me! Great job!
The most criminally underrated channel
The arrows exist in the same 3d space and cast shadows and reflections! You madman! That's a very little detail many won't actively notice but it adds so much! These videos are great in their explaining and visuals
It really is an insane amount of detail to include. You're right, this is totally MAD yet great.
Such a beautiful simple design. I love these self regulating mechanical concoctions
I love this channel. I probably will never user this information but I can't help but to find it fascinating. Makes you appreciate the human ingenuity
Your videos are TOP NOTCH. 10/10 every time. Keep it up!
One of the best channels I've found recently
I LOVE this channel! I love knowing how every day stuff works.
Certainly earned my subscribe with this video. Thanks to the RUclips algorithm for suggesting this one.
Hank Hill approves this video.
Very well made! May I suggest a similar look at the underrated solenoid valves that live in washing machines (and many other types of equipment), that control the intake of pressurized water (or other fluids) with a minuscule force, through a clever internal arrangement.
Thank you very much
Easy to understand 👍
This is great content and and awesome channel 👏🏼🙌🏼
Love your work
Thank you.
Fantastic!
good stuff my man!
just simply amazing content
I love this channel :3
Please do the circuit breaker in the future !
1:15 not all regulators relieve/cent vent excess gas. Limited release models, as well as lockup models are readily available for different applications. They are not legal everywhere.
The vent is not required to be pointed down, the termination is. Almost all models have threaded vents. The screen comes out and you screw a pipe into it, with the screen at the new termination. This means the whole body does not need to oriented in any specific direction, and can also be inside.
I liked another video so subscribed, but I'm surprised how good you are-consistently. Thank you. #FeedTheAlgorithm
Thanks.
If you and technology connections teamed up yall could do some amazing content
You forgot to mention that the main spring is also changed to match the output level range and then you adjust the screw to match the final pressure....
The slot of the adjusting plug is fascinating to watch as it turns through the cut plane, but it would probably be more clear if you restored the plug to its full extent (not cut) for just the duration of the rotation demonstration. Just a small suggestion... the modeling, rendering, and narration are excellent as they are.
Thanks for the feedback!
Nice! Can you do hydraulic valves?
Dual regulator are also used when a considerable drop in outlet pressure needed for safe operation. Smooth flow is easier to achieve with a second stage of regulation. Sometimes more than one appliance, with different demands connected to the same source will also employ a primary regulator for high demand appliance, than step down again for the low demand unit that requires very steady flow.
4:39 dual stage regulators is for safety and control. Typically when there's a very large pressure difference and /or a very wide variability of the inlet pressure. It's one valve body, so it does not help to compensate for distance.
Multistage systems are used used when you do need to deal with distance. You have 2 or more physically separated regulators. Propane is typically 2. (no less no more, not including the appliance regulators) NG will be dozens in series at the very least, most controlled by the utility.
great content, how do you make animations? and the sound and voice?
We use Blender
Thanks!
Thank you!!
The dual-stage regulator illustration should show the second (low pressure) stage much larger than the first stage, because the lower-pressure gas is less dense so larger passages are required and the lower pressure means that more diaphragm area is required. This size difference is clearly visible in the outer case shape of typical two-stage regulators.
Nice stuff man! But please cover some electronic circuits, like the mobile charger (SMPS)
Seal Cap is being loosened and tightened same direction :( Amazing modeling and explanation as always.
Hell yes
Makes sense
🔥🔥🔥
Need a video on thermostatic valve
Is it constantly oscillating or does it settle into an equilibrium state at constant gas output?
Great video, just found your channel recently & love it, but - why the F are they reverse thread?!?!??
Is it a real person reading the script, or a computer? Both the information and description were pretty good, overall, but I’m sure you meant excess pressure, and not access pressure. I thought I was just hearing things, but it was every time, so I think the script could have done with a little proofreading first. Yes, I’m being pedantic, but getting it correct for your audience would be better. Overall, good presentation. Good graphics, and clear, understandable explanation.
Thanks for the feedback, it is a real person reading the script.
Good video. The four screws visible on the body along with the necessity for the vent to face downwards to avoid rain and debris suggests that it's possible to rotate the top half to adjust for orientation of the inlet and outlet pipes. Is that a purposeful feature?
Generally, the safety listing is invalidated when the diaphragm portion is disassembled. Not that you'd actually want to, those springs like to fly. On some models there's an additional set between the diaphragm portion and the body for this purpose. Generally, the body is NOT required to be positioned so the vent faces down. Just the termination, the vent threads weren't detailed in this video.
@@SuperS05 Cool. That's a great point about validation. Thanks for the response.
My only minor critique is it shows the plastic cap on the top with a lefthand thread, which they don't have in reality.
Yea the cap is using the same threads as the adjustment screw. So by that alone they have to be the same handed threading.
so does this regulator vent the gas to the atmosphere if there is too much pressure? I'm quite fascinated by this. I've never seen any used in residential or commercial supplies of city/natural gas/methane gas here in the UK or even in Belgium, France
What program are you using to create these models?
We use Blender
Left pressure indicator is loose 1-2 teeth according to right one.
Do scuba diving regulators for breathing gas use the same type of mechanism or a different mechanism?
Yes, although those are often dual stage. There's different lever arm and body designs but all regulators are designed in this way. Vapour requires large diaphragms, liquid regulators are more compact.
What is the diaphragm made from?
Various materials depending on the fluid and pressure. Vitron, silicone, aluminum, steel are just some examples.
iI do not understand why the outlet pressure does not equalize. I would expect the pressure within the outlet channel to exert some force on the diaphram. I seem to be the only one at 37 comments who still does not understand how stasis is achieved.
The force caused by the downstream pressure on the diaphragm is what causes the valve to close, stopping flow. This causes the lockup pressure to be higher than the operating pressure.
@@SuperS05 Thank you. I checked some other sites and now see what you wrote is what is happening. Regrettably, I did not discern that from the moving arrows in this video. Also, I had watched the video with sound off, but closed captions on, so maybe something got lost in the transcription.
@@johnlaurencepoole6408 I just went read the captions. It's auto captioned and there were a few hiccups in that portion. I can see some confusion there. 👍
Which software do you use
We use blender
I love things that talk about orifices
Access pressure? Lol. Excess pressure! 😂
natural gas is seldom delivered as a liquid to small appliances that use regulators like those depicted in this video.
Neither is propane. You use a vaporizer before passing through the second stage regulator. Often the tank itself is used as the vaporizer on residential class capacities. Propane is only stored as a liquid. (delivered as a liquid to the property not to the appliance)
Dude, VERY cool. Shabbat Shalom!
Beda sama regulator gas melon emak
Natural gas is not a liquefied petroleum gas
It can be.... Just usually only at the oversea shipping portion of the industry. I personally wouldn't include it in that category generally.
I think you mispoke or mispronounced. Excess gas, not access gas.😊
Your narrator or speech A.I. program really needs to know the difference in pronunciation between the words "excess" and "access".
