How a gas regulator works 

Holy crap. 5 minutes, no stupid sponsors, no bs. And I learned something. This is what RU-vid should be. Thank you.

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

Pretty Good Video Here are some corrections/additions: 1. Natural gas is methane and not considered a Liquified Petroleum gas. 2. Liquified Petroleum gases are: Propane, Butane, Iso Butane, etc. 3. The access cap for the regulator adjustment is righthand threaded - not left hand as was shown. 4. The gas regulator shown in the video is very basic - like the one on your gas grill. Almost all gas regulators provided by gas utility companies have a threaded vent port, so that the screen can be removed and small diameter pipe and fittings can be used to direct the vented gases outdoors (if the regulator is installed indoors) or if installed outdoors, to direct the opening down so rain does not enter the vent port. That way the regulator can be installed horizontally as well as vertically. 5. Larger gas regulators (like the one's on most homes and businesses installed by the gas utility) have interchangeable gas metering orifices and adjustment springs. Changing the gas orifice size, changes the volume of gas that can flow through the regulator, while changing the spring stiffness, changes the range of outlet pressure adjustment capability.

You are the first channel I've seen that acknowledges that the diaphragm actually flutters to maintain the outbound pressure

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

Such a beautiful simple design. I love these self regulating mechanical concoctions

Your videos are TOP NOTCH. 10/10 every time. Keep it up!

One of the best channels I've found recently

Excellent video. As long as it needs to be and no longer. No useless intro about what the video is going to contain, no history of regulators, no intrusive music and no ai Voice over. Well done mate

I LOVE this channel! I love knowing how every day stuff works.

FEELING LUCKY TO FIND ABOUT THIS CHANNEL

amazing explanation thanks for keeping it simple

Hank Hill approves this video.

good stuff my man!

Love your work

Easy to understand 👍

Certainly earned my subscribe with this video. Thanks to the RU-vid algorithm for suggesting this one.

I love this channel :3 Please do the circuit breaker in the future !

Such a simple yet ingenious design, yet the quality of the propane gas regulators in the market is infuriating. The video is amazing to the inexperienced, I admire your content. Thank you

Fantastic video!

Excellent rendering!!!!

Fantastic!

This is great content and and awesome channel 👏🏼🙌🏼

Thank you.

just simply amazing content

A great animation video about regulator working method

I liked another video so subscribed, but I'm surprised how good you are-consistently. Thank you. #FeedTheAlgorithm

Understand very easy 👍

Thanks.

Thank you very much

Man if only people realized how much it would save them in the long run to install gauges before & after devices.

Thanks!

Nice stuff man! But please cover some electronic circuits, like the mobile charger (SMPS)

Super good video! I would also like to know how an automatic changeover regulator, used when you have two propane cylinders, actually works to switch between cylinders.

🔥🔥🔥

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.

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.

great content, how do you make animations? and the sound and voice?

0:24 Right handed threads on both of those pressure gauge nipples. Kudos for that little detail!

Hell yes

Makes sense

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.

I wish you woulda shown the propane high flow cutoff system.

Can you make a video about how backflow preventors work?

If I'm not mistaken, it's the same basic design principals behind a SCUBA regulator, though it has much more pressure changes to deal with.

Seal Cap is being loosened and tightened same direction :( Amazing modeling and explanation as always.

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.

Couple points. The relief valve is a safety device in case the seat disk does not close off 100%. If it is venting at all, then a repair is in order.

Nice! Can you do hydraulic valves?

If you and technology connections teamed up yall could do some amazing content

The regulator will also blow gas out the vent if the diaphragm fails. I just had to replace the one on my camping stove, which is no doubt how this showed up in my feed after ordering from amazon.

Need a video on thermostatic valve

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....

❤❤

1:15 not all regulators relieve/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.

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.

Great video, just found your channel recently & love it, but - why the F are they reverse thread?!?!??

Is it constantly oscillating or does it settle into an equilibrium state at constant gas output?

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

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?

Do these also function as non return valves?

Question: What is access pressure? I have never heard this term before and do not understand it's purpose and use.

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.

What program are you using to create these models?

Do scuba diving regulators for breathing gas use the same type of mechanism or a different mechanism?

What is "access pressure"?

My only minor critique is it shows the plastic cap on the top with a lefthand thread, which they don't have in reality.

Left pressure indicator is loose 1-2 teeth according to right one.

What is the diaphragm made from?

Which software do you use

I love things that talk about orifices

Access pressure? Lol. Excess pressure! 😂

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.

How is that possible I can watch this video in pip?

You say axis pressure. You may need to say excess pressure. Excess is the proper word in English for too much. Beautiful drawings and animations.

I think you mean to say ‘excess’ pressure, not ‘access’ pressure. One letter but big difference.

natural gas is seldom delivered as a liquid to small appliances that use regulators like those depicted in this video.

Dude, VERY cool. Shabbat Shalom!

Don't need the background sound effects they're distracting

I’m scared of these, like what’s the chance of it not exploding? I don’t mind dying off of it but being harmed? No thanks

Beda sama regulator gas melon emak

Your narrator or speech A.I. program really needs to know the difference in pronunciation between the words "excess" and "access".

Natural gas is not a liquefied petroleum gas

I think you mispoke or mispronounced. Excess gas, not access gas.😊

You wasted half of the video, talking about the inlet and the outlet on the screen.

Thanks!
