Safer Tanks

I was thinking like a hose could be connected to the inner part of the tank and have something to stop the valve from flying off like a stock 98 squeegee like thing except shorter and with an opening for the CO2 to enter through.

The small rash of valves fireing off where from <Insert crude, rude, vulgar explicit words which would cause me being guested and likely IP banned, pardon me mods> techs who added anti-siphon kits and other modifications involving the removal of a valve to tanks without loctiting the valve in place and rather just screwing it on, causeing the valve to go off. I am assuming you mean something like this : ------------ \          & ;nbs p;     {   \                {---====0          & ;nbs p;     {   / ------------ / Another thing tanks have are burst disks which will break long before the tank or valve will, releasing the contents of the tank rather quickly and loudly. Keep thinking, one of the few good ideas I have seen around here lately.

how fast so the burst disks actually  come off? DO they come off? becuase if that thing is gonna burst and its gonna go flying could it not cause some major damage?

i like the idea for a safer tank. anything that has the word safe in it is a good thing to get those paintball skeptic of our backs that think we are fireing kalashnikovs at each other

YAY, It worked!

Burst disks dont "shoot out". Theres a little hole in the middle inside the hole cut through it. When pressure is exceeded the spring will give, and the air will vent through the holes.

How often does a tank valve come undone? Like twice in 15 years. You have to be pretty dumb to not notice your unscrewing ten threads length of the wrong part...

This is incorrect. A burst disk is a little metal wafer (brass?copper?) that is inside of a hollow screw, for lack of a better term. When a burst disk gives - it bursts. There is no spring or anything like that. The pin valve has a threaded hole in the side of it. The burst disk goes in this hole, then the "screw" goes over on top of it. This "screw" has a hole leading to the rear, with little holes leading out of the sides to vent the air through. I have seen them rupture, and they destroy the little wafer of metal inside. Next time you're at a proshop, ask them to see the pin valve's internals, or at least ask them to see a rupture disk for CO2.

just put some duct tape on that sucker.

First off, you've obviously not had it happen to you. I had tanks seperate two different times now. The first time I was talking to someone and unscrewing the tank. I heard the usual hiss of escaping gas and kept turning. A second or two later I had the realization that there was way too much gas venting. When I looked it had come out past the relief holes in the lower part of the valve. The second time was with a HPA tank. I started turning it at realized that there was a problem immediately. I am not a naive kid, I have a family and work in a specialty field. Secondly, from what I remember the people that got hurt were innocent bystanders. I know that a mother died in one incident. Do the uneducated deserve to hurt others? Think of how people stand when removing tanks - usually they are holding the paintgun sideways, which would make the bottle discharge into another person; not them.

Dire Wolf wrote: A while ago some CO2 tanks got recalled since the burst disc holder had no hole in it to actually relieve pressure if the disc burst. Check yours just to be sure. No hole on the side of the nut = unsafe.

Very true. Look to be sure.

Duck tape sounds pretty good to me. Use it as a mark to know if the tank started to seperate.
