How does a burst disc pneumatic work?

[airpress]

Hi.

I've a question.(look the title of my post)
I will try to make once a other type of pneumatic.
But i dont know what size of chamber,barrel,burst disc,unions,... i would use.I will put 125 psi on it.Please give me information.


Thx,airpress.

basically you put something like aluminum foil or PET plastic in the union, then you pump in pressure into the chamber, eventually the burst disk will reach its failing point and it will burst, this gives you a full barrel sized flow, and is the fastest valve you could ever use

I dont know what an union is.
So, i can use to thin layers of metal sheet?

Spudshot:Thx for the info.

sheet metal might be too thick, if you cant get unions in belgium you can use a male and female adapter, just put aluminum foil over the male end of the fitting

Ok.
I will do it like that you said,with a male and female adaptor.
I will use an 1" chamber,i think.[/img]
