Can someone explain my regulator?

[mysterio]

I got my cornie set up through the post this morning. Looks great. Although I can't figure out how the regulator works, I'm a bit thick when it comes to these sorts of things :rolleyes:

I figured out where the gas line goes in and the opposite end screws into the cylinder. Do I just need to buy a pressure guage now? What are the other bits for?





Oh yeah... and if anyone knows where I can get a CO2 cylinder refilled cheaply in the Glasgow area let me know

I had a similar reg from norm


I was thinking that i might be able to unscrew the two brass lugs and get a couple of gauges to screw in but i'm not to sure now <_<

[mysterio]

So what can you do with it?

I was thinking that about the lugs too.

[IanRMartin]

I must admit i'm tempted to just buy a new reg with two gauges and fle-bay this one.

[IanRMartin]

After a bit of research i think the lugs are blow of valves to prevent over pressure situations, so they may not be tank pressure or delivery pressure just intermediate pressure steps in the regulator. But i don't know!

[tribs]

IRM, contact Norm. I'm sure he would replace them with something more suitable. I don't think you're that far away from him so you could arrange to meet and save on postage costs.

mysterio, is your gear from Norm too?

[mysterio]

Yeah, I emailed Norm and he says mine is set at 12 PSI. Which I reckon will be fine for my lagers if I carb them in the fridge. I suppose I would just pull the pressure release a bit when I want to serve? There's also an adjusting screw on it to increase/decrease the pressure so I can faff around with that.

It's a standard black free flow tap with about a foot of 3/16 line.

I have a similar regulator on its way with my keg (no gauge). Norm mentioned there is a screw which can adjust presssure in either direction. 10/12 PSI is a little low for my pale ale - anyone know what range this screw will adjust to in either direction?

Its going to be hard to adjust without a gauge to see how much of a pressure change there has been!

After a little more research i believe the two safty pressure valves are 1 high tank pressure and 1 low delivery pressure while i think it would be unwise to replace both with pressure gauges i don't think it is to much of a risk to replace the delivery one with a gauge.

As far as i can tell gas regulators have two thread types:
Old regs 1/4 NPT
newer regs 1/4 BSP

There are a number of places out there which will do gauges sutiable one i found is this place http://www.pressuregauge.co.uk/

They do all sorts of gauges in all sorts or ranges give them a call or check there website out they have a guage configurator.

Daab i wouldn't mind seeing that, especially as i don't know the difference

Only when you have time, no rush

[IanRMartin]

Is ID internal diameter?
Whats OD?

And when you said its measured by the ID of the associated pipe work, do you mean you would measure the Internal diameter of the nut or hole the thread screws into rather than measuring the thread its self?

Can you tell i don't under stand engineering :blink:

[IanRMartin]

QUOTE (Daft as a Brush @ Aug 18 2006, 11:17 AM)Yes...ID/OD...internal/outside diameter

You cant tell the ID from the id of a gauge as it has a restriction which is why I used the phrase associated pipe work.

In many applications lengths of pipes are threaded an each end and joined with threaded couplings, elbows, tees etc. (and also has things like pressure gauges fitted to these tees or even welded threaded nipples).

These fittings, including pressure gauges are partly refered to by the internal diameter of the pipe they are designed to screw to.

ie a 1/2" coupling (connecting piece) connects 1/2" pipe but doesnt measure 1/2"

:blink:
Surley it should be internal and external were on earth did outside come from !?

Also i have now decided i don't like egnineering its not logical

[mysterio]

Niall, Norm said the regulator goes up to 40 psi. I'm just going to play it by ear I reckon, crank it up a bit at a time (until it explodes :rolleyes: )

This cornelius keg business is getting expensive fast! Think I'll need to wait for my student loan before buying any more gadgets

[IanRMartin]

How can they state the Outside diameter of the pipe the walls could be thicker or thinner leaving the Internal diameter of the pipe the same.

Or does it mean the ID of the pipe is what you measure to give the OD of the thread??

let me put it another way taking your example you have a 1/8 NPT thread bolt what ever you want to screw into a pipe what does the .405" refer to on the pipe the internal diameter or the OD? if its the OD how do you get on with thick walled pipes??

My head hurts
