Relief's in place of burst disc's?

[Mouldy]

Hi all,

Been looking at my robot and I don€™t have space to screw a relief valve into my reg (robots to small:sad and I considered this idea and didn€™t know if it was legal:

Would it be legal for me to unscrew the burst disc from my fire extinguisher and put a relief valve in its place? So the relief is constantly attached to my bottle? Just a thought...

Dave,

I strongly suggest you leave the burst disc in the extinguisher alone. Replacing the 190 bar with a 1000 psi relief valve is not wise, you could get the CO2 venting from the extinguisher on a warm day / in the car etc. There are other reasons why this is also not a good idea at all.

cant you put the valve somewhere else on the HP pipe? assuming your still using the reg i made, the compression fitting on the reg and Co2 bit both have 1/8threads. why not one remove one of the compression fittings and put in a t piece and a 1/8 to 1/4 fitting.

Oh ok Paul, Ill leave It be

Yes, im still using the reg I got from you Alan...But space inside the robot wont allow me to put it in the reg

Guess ill have to make a fitting or somthing..

Do featherweights even need a relief valves yet?

*sigh* why are LP rels really nessasairy!? I carnt see a surge of pressure going into the lp side of a setup and even if it did happen whats the worst that could happen?....A pipe comes out of a pneumatic push-fit, Am I missing the point?

what happens if the regulator blows and lets 1000psi into the system? BANG!

well.. thats why Dave suggested the fire extinguisher.. so if that does happen Alan, Daves got backups! *giggles*

*pats Dave on the shoulder for being so concerned about safety*

Dave, yes you are missing the point. This subject has been discussed on this very forum before. Perhaps you could advise me at what pressure a push-fit will fail.

Ok guys - I get the point now:sad:..

Isnt it somthing like...a 10bar pushfit will blow at 15bar? and a 12bar at 18bar etc...

Audrey, not that I need to explain myself to you, I have a lot of time for Dave and Im sure he knows it.

Thanks Paul, I know you have time for me, but I feel your comment about advise me on the push fits was harsh and sarcastic. I was not aiming any of my comments to ignore your comments, as I know you may have more knowledge on pneuamtics than I.
Thanks and sorry.

P.s. Thanks for your outburst of randomness Audrey

Dave, the question was not intended to be sarcastic and apologies if it came across that way. It was intended to encourage you to think through your argument rather than just be told no, do as you are told (which was in my opinion the Mentorn way).
