How a gas regulator works

In this video we will look at the mechanism inside a gas pressure regulator.
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.

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.

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

[@KenFullman]

It really is an insane amount of detail to include. You're right, this is totally MAD yet great.

[@Zzrdemon6633]

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

[@SmackMyKeyboard]

Does it actually flutter? I would imagine that under normal circumstances while the gas is flowing, it would reach a steady state where the inlet hole is closed just enough to allow for some gas movement.

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.

[@JGambrosia]

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

[@JoseSilveira-newhandleforYT]

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.

[@rong1924]

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

[@michaelabiera]

Nice! Can you do hydraulic valves?

[@Pazuzu-2048]

Can you make a video about how backflow preventors work?

[@seranonimo6770]

Makes sense

[@johnchaney8727]

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.

[@ChrisToffer1]

Need a video on thermostatic valve

[@deletdis6173]

[@hornetscales8274]

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.

[@digger105337]

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.

[@brianb-p6586]

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.

[@shermanharvey9519]

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

[@Deconstructed_Animations]

We use Blender

[@LBS4]

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

[@theDane70]

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....

[@AB-vc7ox]

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.

[@mouchoirs_blancs3582]

🔥🔥🔥

[@SuperS05]

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.

[@punkdigerati]

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

[@joshdaly2343]

Do these also function as non return valves?

[@VishalDudhani]

❤❤

[@xTerminatorAndy]

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

[@brianb-p6586]

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.

[@Deconstructed_Animations]

Thanks for the feedback!

[@Gator-357]

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

[@SuperS05]

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.

[@boby115]

You are correct until we start talking about vent limiters , those need to be mounted horizontally, along with the regulator (using piping to mount the limiter horizontal is prohibited by manufacturers, such as Maxitrol).

[@SuperS05]

@@boby115 a vent limiter and vent extention are mutually exclusive. It's one or the other. Vent limiters aren't allowed here anymore.

[@stephenmeeks684]

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.

[@SmashCrunch]

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?

[@SuperS05]

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.

[@SmashCrunch]

@@SuperS05 Cool. That's a great point about validation. Thanks for the response.

[@RustyCarnahan]

What is "access pressure"?

[@cody75]

What program are you using to create these models?

[@Deconstructed_Animations]

We use Blender

[@ZetaPyro]

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

[@SuperS05]

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.

[@vivalesvegas]

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.

[@Deconstructed_Animations]

Thanks for the feedback, it is a real person reading the script.

[@yyabay]

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

[@Niightblade]

What is the diaphragm made from?

[@SuperS05]

Various materials depending on the fluid and pressure. Vitron, silicone, aluminum, steel are just some examples.

[@WorldofTech5]

Which software do you use

[@Deconstructed_Animations]

We use blender

[@daviddun1389]

I love things that talk about orifices

[@paddyglenny]

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

[@SuperS05]

Yea the cap is using the same threads as the adjustment screw. So by that alone they have to be the same handed threading.

[@dogieeu]

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

[@62Cristoforo]

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

[@videodude8137]

Access pressure? Lol. Excess pressure! 😂

[@johnlaurencepoole6408]

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.

[@SuperS05]

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.

[@johnlaurencepoole6408]

@@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.

[@SuperS05]

​@@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. 👍

[@scottprather5645]

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

[@waynepetrevan]

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

[@SuperS05]

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)

[@dogieeu]

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

[@ColCurtis]

Natural gas is not a liquefied petroleum gas

[@SuperS05]

It can be.... Just usually only at the oversea shipping portion of the industry. I personally wouldn't include it in that category generally.

[@MottyGlix]

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

[@preferredcustomer3527]

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