First Barrel Sealing Valve
Posted: Sat Mar 04, 2006 3:49 pm
Howdy folks! This was my first attempt at a Barrel Sealing Tee Valve and overall it turned out pretty nicely. I had quite a lot of difficulty getting this thing to seal air tight at first, but with some help from Izzy I was able to get this thing working. It's pretty much an exact replica of Izzy's Son of a Zonker but with my 360 Ball Valve Hopper on it. It's 1" Sch 40 with 3/4" Sch 80 barrel and hopper. I have a brass tee connecting my quick connect and blowgun to my chamber. I have 8 10-24 x 1/2" machine screws holding the end plug onto the tee. My diaphram is 3 1/16" neoprene rubber discs with no equilization hole. I have: bolt -> washer -> 3-ply diaphram -> washer -> lock washer -> nut. I can only get it up to ~70psi and I think this is beacuse my pilot valve can't dump the pressure over 70psi fast enough to actuate the diaphram. I was thinking about getting a 3/4" Watermaster or a QEV to solve this problem. Enjoy!
