I wanted to pressurize a gas tank with an Impeller Pump. I prevent back flow by adding a Fluid On/Off Valve. But after filling the tank and shutting the system off (pump and valve) the tank looses all it's pressure.
I condensed my system to a minimalistic setup and yes - there must be a bug in the new pressurize system.
The Test-setup has the following components:
- Gas Tank (small) (empty)
- On/Off Valve (between impeller pump and fluid port)
- Impeller Pump (small)
- Small Electric Motor for the pump
- Fluid Port End
- Numerical Switch Box
- Toggle Button
- Constant Number (1)
- Battery
With the Toggle Button the pump and the valve starts working, the tank gets pressurized. When switching off, pump and valve are off but the gas escape through the (closed) valve.
