A quick few questions..

Unread postAuthor: bobsta » Sun Oct 17, 2010 7:11 am

Hey guys,

I have a couple of probably simple questions..

As you will notice I have uploaded a picture of DirtyDan's combustion cannon, i just have a few questions about it !

Ok so green 1, 2 & 3.
1. The valve to the 'propane' tank
2. The only reason I see the use for this valve is so that you can hold the pressure between valves 1 and 3 for an extended period of time and not worry about pressure in the rubber tube between valves 1 & 2.
But why wouldn't you just remove valve 2 & remove the rubber tube, and just have brass fittings from valve 1 to valve 3 ?

Wouldnt that work?

Don't worry about the Red 1 and 2. I figured that out.

Hopefully you understand me :D

You are new. Search Propane Meter and it's function should show the reason for 2 valves. Between 1 and 2 is a delivery hose. Between 2 and 3 is a calculated volume for the metering of propane.
