Suggestion. On both sides of the last tube to be inserted, cut 1/3 of the way through this tube about one quarter inch from the end. Then cut up to the first two cuts that were made, taking out the square/rectangular pieces that were made. This replaces the the nail and removes the last steps of putting the nail in and glueing it. Now all is plastic, cutting the chance of rust and damage to the check ball. Maybe the check ball could even be made out of rubber which would remove the steps of punching out the hole in a piece of rubber and glueing it to the smaller plastic tube. This replaces two items, and three steps. It also allows larger or smaller tubing to be used as long as the correct size rubber ball could be found.
Great video 👍. Just a suggestion 😊
I am trying to visualise your idea about cutting the last tube and not using a nail... wish you could make a video too.😢
@martvogt7019 You sir...are awesome in your wording. Maintaining a suggestive nature along side relaying your idea with excitement and detail, all while keeping the original idea mostly intact. Thank you sir; might be hope yet. Maybe even a light weight spring...😊
Thanks so much. Your idea gave me a start to do something a little different but I wouldn't have started with getting inspiration from your video.
Hey man, it's great! This is the simplest and the easiest way to make a check valve among all the videos up on the CZcams
Cutting Cut Thanks! indeed and it works as good
@@johnbelwell2461 what about my check valve i get it for free too czcams.com/video/D_yjwjuhUDs/video.html
Thanks for keeping it simple and easy to reproduce, great video!
No problem,glad i helped. :)
Thanks for sharing, Love the idea of making it out of everyday things. Thanks
No prob :)
Very cool I have made these out of PVC pipes before but never thought of using them this small, but it is right in line with what I have been trying to find all day on line. I need some 2 part plastic clips of liquid ports to join 2 vessels as well as a low voltage all plastic liquid pump. these are for my humanoid robotics build I have been working on for a bit now I am onto something that seems to be avoiding the big boys at the big schools and companies. If I can get the rest of the parts I will display it here so they can see my fix. keep the videos coming I will be watching.
Thanks for your input. Seems like you're having a great time with your project. :)
Excellent! Very useful!
Nice use of the hole punch!
John, you could use a set of 2-3 pistons to obtain rotation, a pressure valve to create combustion in the pistons, and woodgas to fuel the combustion, to create an engine. The gasification chamber would be heated by the charcoal made while obtaining the woodgas. The great part is that one can use many sources of fuel, from wood, to grass, from wet to dry, from big logs and coal chunks to coal dust and pellets, thus showing people how one could make an engine for all sorts of uses.
Like making a self-rotating signal light in case of emergency, which uses a tiny amount of fuel and a bearing, to rotate something around a source of light (like a flame) to be used as a signaling light, if there isn't a good enough stream of water or wind in the area at the time. Or using it to rotate a terracotta/cement/metal wheel so one can sharpen tools and sharpen rocks to make tools if&when needed.
Also, if enough fuel is present, one could possibly make an engine for movement, like a boat, or car(t). One only has to stockpile some fuel before deciding on a direction, and to make sure one has at least 2 speeds (one being reverse, recommended 1-2 for building forward momentum), and a steering system, and one can get much faster by car than by foot. If the terrain is not ideal, one could use rope and wood to make tracks for the wheels, or just make really wide wheels. A gear box is not that difficult to make, either, so one could easily reverse the direction, as well as increase the speed at the cost of carrying capacity.
The good part of that is that by making a playlist of videos showing one how to make a wood-gas engine from scraps, one can help those in need who have the time and resources to have that built, to build it. So, for example, someone in the poor parts of Africa or Asia could build a vehicle that would allow one to move goods, and by moving goods one can make a profit. For example, one could carry water and food, or cut wood, or grind wheat, or make grass pellets, or power a water pump. Using different input sizes, one could increase the speed at which the water is pumped, and if a channel/tube is made (terracotta and cement can be used, if cheap enough, and burried for lower chance of implosion) or installed, one can easily move water many kilometers instantly, so a union/group could get water inland virtually instantly, regardless of the dunes in the desert.
Heck, even a cheap PVC piping, when burried for lower chance of explosion, can easily allow water to be moved many kilometers. If needed, one could even use multiple pumps, or bigger ones, so someone can pump water for a weekly fee some part of the distance, someone else can pay that person for water pumping and be paid by others to pump the water even more, and so on. Thus, a 1m-thick water stream on the beach could be spread and end up being a 5cm-thick water stream 5000km inland, for example. Moreover, the ones maintaining the system can work legally, so there's no problem there, and the flowing water would ensure that there won't be much salt debree piling up. Also, using an archimedes screw for pumping water, one could also move fish. The speed is also a factor, since one would have to mess with the gearbox to find the best fuel-water efficiency.
I really like your idea and the nice way you wrote it. I'm not sure if i would be able to implement it,but it is a pity to not share all this nice information perhaps on a forum or something like that. You seem like you know this topic real well. Well done!
Well, the information is on the internet, but there's not one site that acts as a hub for engineering, permaculture, minimalism, and more. Well, aside from youtube.
Also, you could use stainless sheets of metal as a parabolic mirror, to reflect light on a pipe or a smaller parabolic mirror behind the pipe, which would heat up air. Having that air circulate through a loop leading to the head intake of a stirling engine would be enough to get it moving, and once moving it can power one fan for the heat intake loop and another one for the cooling intake (which can be just normal air). There could also be another loop, for burning fuel to heat the air used to transfer heat. Some use water or antifreeze, because it needs (much) lower speeds than air, and circular solar concentrators use salt, but a high-speed fan and a funnel are enough to speed up the air. But the "linear solar concentrator tube" is enough for that.
Below are 2 links to a video that shows how cheap energy can be achieved. And although it might not be as much heat as from other means, the usage of a stirling engine allows for possibly higher energy outputs, because it uses only a temperature difference to generate motion (rotary power), which is a form of energy that can be converted to electricity pretty easily. Teracotta bricks / fire bricks can be used, as well as rammed earth (5% cement and the rest dirt, packed down really well) with tubes (helix or zigzag) for transfering heat (with the same substance, but if it's not air, you would need to have a layer between the liquid and the storage medium), to be used at night (when the temperatures are lower outside, giving a higher temperature difference; also, 24/7 power generation).

I was here for the exact same reasons. Best of luck with your ventilator sir!
No problem, hope you have success with it.
Exelent work Man i congratula te
Great job...I will make this with metal for my vacuum chamber 👍👍👍
It will be better if you put the nail as close as you can to the ball so the valve close faster to not lose some gas, but dont put it too tight if not cant work
I'd give 2 thumbs up. 1 for the blues tune. Dig it.
Haha thanks!
wow ide yang bagus😊
Perfect I was looking for something like that
Glad if i helped!
great job
At 2:33 I'm pretty sure it's not supposed to spray all over the place. I had the best laugh of the week at that point. Thank you.
Hahaha yeah,it was slippery and quite hard to hold it by hand when the pressure increases.
I loved that you didn't remove that part.
Word I agree. Most people would’ve edited out the spraying water but you left it on. Shows you have enough confidence to know it works when really applied.
Awsome!!! Thanks for the idea!! I will be doing this for sure!
No problem! Glad this helped you. :)

I got a shower valve repair kit that comes with rubber rings and springs. I guess I could use that to substitute the nail and the rubber. I just need 2 tubes and super glue? The hoses are polyvinyl? Maybe theres a better glue cause super glue tends to crack and oxidize or break down under uv.
Hello. I guess if the valve repair kit comes with a pipe you can use that to make something like this and use the o-rings to substitute the rubber i used.
Best to use solid PVC pipes of any diameter with the necessary fittings to make something that looks like in this video, and as for glue, i suggest that you use PVC glue instead of superglue on hard pipes, but if you plan to use it for anything drinkable be sure all the material is food grade.
Thanks.

I need something like this for a radio controlled submarine
Gracias
I need one designed like this , but with a spring so that only slight vacuum will allow water flow out , and then seal with no vacuum in hose. (adjustable spring pressure)
recomended
thanks for technology transfer [ToT]
I want this type valve to purchase but can not find anywhere, all valves I find uses Spring or Rubber or Swing. so non of them are free flowing on one side like this one...if anyone knows where I can find it, please let me know...I know it is easy to make but I want this for my car and I do not want to gamble since it will be introduced to lot of heat cycles and oil. great vid
A small (in length) spring could be used to make the check vavle into a pressure valve. Or the use of a weight might be justified, if a spring is not available.
That is a good point. Thanks.
ooh, i like that idea for the vacuum pump i want to make. thanks.

what was the ball from? Can you use a marble or is it too heavy?
It was a ball for plastic jewelry,and yeah you can use a marble,why not? Just i think it will be too heavy for a low flow air application,for something as dense as water it should be alright in most of the cases as far as the valve is placed horizontally,or if it's having a spring behind the ball forcing it to the direction the valve works to.
so when it popped out of the water hose is this only because it was not properly secured to it?what good is this for exactly? i can not use this as a safety device like a flashback arrestor on my blow torch
Yeah, when the pressure raised it popped, indicating the flow was restricted by the valve's operation. You can use this design for everything, just make it out of copper piping, and for gas use suitable rubber that will not disintegrate from the fuel.
@@truebassB ok ty
Is it possible to avoid the nail and instead, cut the edge of the outflow-side tube into a V shape? I know it'll be effective for low-flow applications, but, not for high-flow. It depends on what it'll be used for. A low flow application is brake bleeding for example. Have you tried it with a tube that its edge is cut with V cuts all around? I'll be trying it to see if a little air or fluid can go through those teeth looking cuts. For a washer, I'll use a good quality that can resist acids and fuel. They are from the oil filter of a GLK350. Four sizes in the package. I won't use cheap washers made for water. And a 100ml syringe. Any other ideas how to avoid that nail? Maybe distort the main tubing by heating it and pressing your nails on it. Then, use that distortion as the middle of the device. Then start cutting the tubing. Hopefully the distortion won't let the ball go to the other side. Trial and error will lead to success in the end. Oh, did I forget to tell you? Your video, your thoughts, your presentation is impeccable.
What you say will work just as fine as the nail,it is how i had it made for the first time,it just could not give as much clearance as the nail for the flow to pass. Another way to avoid the nail is probably a metal mesh,but your idea about distorting the tube is interesting,especially if hard pvc pipe is used instead of flexible.
I appreciate that you like my video. :)
John's Crafting Lab You are very right about the amount of clearance and a metal mesh is a perfect solution for high pressure flow. In my case I need to make one for bleeding brakes and the force of gravity is not enough to seal the inlet. And if I hold it the other way it will never be any seal. I started by looking for marble. I took a small one out of an old swivel office chair. A stainless steel ball that was a part of chair's bearings. This is my marble now and fits nicely in a syringe (syrup for babies). Now, I'm looking for a spring to provide a tight seal independent to how the device is held. If I can't find the spring i won't continue. I'll just cover the tube with my thumb when I evacuate the brakes. Syringes are very useful to work around the car. I labelled all of them. One for only water, only oil, only brake fluid, only power steering, etc. They are 100 ml and only $3 each. That's how I added the new differential oil on my Ford Escape. And the power steering fluid on my GlK350. Also, I use a 1.5 liter syringe for oil change. I tested it on my Chrysler a month ago and I extracted a liter in about a minute. It needed modification thought. For a lazy oil change I modified a Toro leaf blower/vac to reduce it's huge opening into the size of a shop vac tube and with the help of a separate canister filled with vacuum, all the oil comes out in less than 10 minutes. I did something similar in the past with a regular shop vac and it lasted for years, but, eventually the motor gave up. Too much heat in the bucket. The Toro is air cooled because it's not inside any bucket. I'll update you later on my check valve. Before closing, I must tell you don't stop doing these videos. You'll be a huge success. Trust me. People like such videos. For example, get an empty mason jar, install 2 plumbing valves on its lid and make an oil catch can. Talk to you later.
You could glue/weld something to stop the ball from blocking the other end of the valve, while still allowing water to flow. Or just cut that end of the inner pipe into a zigzag or sinusoid pattern to allow the water flow. Did I understood the problem correctly?
Also, you could use a fan, or a fan with a funnel to pressurize the air and more easily direct it to the parts that need cooling.You can even put the engine in it's own enclosure so that the air that comes in presurized would be directed in it's way out, so as to not heat everything else around it, or just use two fan-funnel systems, one one-funnel (to push the air in the small tube) high-pressure air-push, and one two-funnel (one at each end) air-pull.
What was the rubber inner tube part for? Ohhhh, to help the ball seat airtight...okay!
oh yeah
good bro
thanks
Can I suggest an idea??? If you don't have a metal ball try using a marble.
need 2 for a test, so you can see which one it comes out of out of the 2 directions.
Can one use this to give rescue breaths?
I guess so, if you have to use one.
Question ..can water pump attached to flowing pump act as check valve..We get water from municipality for short time and we use pump attached to water pipe line to pull into water sump, my question is if the input is raised we don't get pressure. If we have same level .local plumber says the water will flow back to main line. My question is will the water pump act as check valve
If i understand this correctly, you have a water pump where you want it to act as a check valve. From what i can say, there's a good chance for the water pump to have an integrated check valve on it so it might work.
Why not krinkle cut the end of the second small tube and get rid of the nail?
It doesn't need a nail necessarily. Just slit along the outgoing tube (the side where you had stick in the nail) But maybe less flow rate.
Good point.
I like your video one thing you could do instead of putting a nail in there to leave some space simply cut the tube on that side with a 45 degree angle when you put it in and then the marble has no way of making a seal and you won't have to worry about a hole in your check valve
To tell the truth i did made some experiments with it being like that and that's the best idea, only problem is if the tube is too small like the one i've used, then its wall is going to be thick, thus limiting the flow at some extend, whereas a nail leaves the full space between free.
Although if the tube is bigger and you use, let's say a pipe and a marble, the way you say is the best way it can be made.

Yeah using metal pipes and a metal flap instead of a ball, i don't see why not, but why?
hi dear . can i ask you why you put the rubber piece there
Hello. That is placed so to act as a seal.
hmmm . thank you so much
@@hamadaplanet3151 No problem!
❤❤❤❤❤❤🌺🌺🌺🛎
What's it like in low pressure situations?
Great, as far as the flow is sufficient to operate the valve the way you made it, for example the seal at the ball plays a great role, the smoother its contact is, the less pressure and flow it will need to operate completely.
John's Crafting Lab I did My system without a valve. I wanted maximum flow.
@@petercohen3966 sounds good.
love choice of music. my wife is an engineer so i'm double turned on

Will this also work with air?
it should

Mostly.... I used water just so the demonstration is visible.

Thanks a lot.

One way air check valve make please sir.
Hello, this is one of those.
What is the material of the ball?
It can be whatever you want as long it has a smooth surface.
In Soviet Russia valve check YOU!
I think a diaphragm check valve might be easier.
пропускаєт))
you should have used the spring to push the ball
Correct,that's the ideal design,but you need a high pressure application to insure it will work,the same goes to springless design,but this needs high flow to make it work.
One could have two valves, a smaller one for lower-pressure, and a bigger one for higher-pressure.
it is not good and not strong to put the smaller pipe inside the bigger one then add super glue from the outside! You should put super glue first on the smaller pipe then insert it in the bigger one so that glue will cover a wide area between the two pipes and stay longer !! hint: you should use special super glue for rubber !
Hello. Good advise! Thanks.
no!
Bro this valu go air on this
Does not work for air. Only water
It works for any gas or fluid, as long as your build has a strict precision.

Epic fail!XD
Obviously your demonstration was a failure
And the final 30 seconds were to show....how klutzy this 'home made' craft was??
no. it was to show how well it sealed and kept water from flowing. the reason it did what it did, was because the water pressure was too high to keep the valve in place in the hose.
Total failure!!!🤣🤣😁🤪
Does this work with air?
It will work with air, but i would suggest translating this design into metal pipes, since they won't deform as easily when under great pressure so leakage will be non existent (unless you use it for extreme pressures)
@@hardcase1659 i would not use this as a flashback arrestor
@@hardcase1659 Exactly what hard case he said.
@@ARCSTREAMS The volume in the chamber is too low for any significant pressure to build up if a flashback occurred, plus the softness of the material would sooner deform and let all the excess pressure from the explosion out rather that fragment, which would not cause any harm to a person anyway unless a fragment went into their eye.
@@hardcase1659 not sure if you are talking about metal or the plastic tube in the video which is what i was referring to ,i doubt it would work properly to shut out a flash back in time ,better to not mess around for such use and get real one,,of course if i made one myself for such use it would be a bubbler with water chamber,,much safer
