if you have a QEV you would want one between the QEV and the fill valve.

no use for one in a combustion.

Uhh, yes there are uses for check valves in combustions... say you build a permanent venting system for the launcher using a mattress inflater. Connect the inflater to the check valve. When the combustion occurs, no damage occurs to the mattress inflater due to the check valve; however, the mattress inflater can still push air through the check valve to vent.

A check valve is just a valve that lets gas or liquid one way, but not the other, so the QEV won't fire when you disconnect your pump.
