(Snap-on?) Check Valve Types
(Snap-on?) Check Valve Types
(OP)
Hi,
I'm searching for a valve that has the same working principle as the ones in the water tank of Nespresso coffee machines, meaning that i can "snap" a container in its place and remove it without using additional "unlatching" operations (like in the quick release coupling, where a lock ring has to be depressed) and the valve is opened by a physical feature that displaces sealing element (not by pressure differential).
I want to incorporate the same principle in my design where the fluid tank can be connected and removed easily and quickly, but i cant find anything useful so far.
Thanks,
SD

Per ISO-4126, only the term Safety Valve is used regardless of application or design.

If you remove the locking ring then often there is a force there when needs to be accounted for.

Honestly I'm looking for anything that might give me "traction" in finding the right component.
The pressure is atmospheric, flow rate is 0.5LPM, the fluid is foam (for simplicity lets say foam from soapy water), and the tank is placed in its position (the valve engages) when its empty (the foam is added later on).
I'm guessing those are pretty benign conditions and will not present much of a challenge to any component.

Seems very coincidental...

An absolute coincidence!

A litter off the wall but you could adapt the principle behind downhole safety valves.
See https://youtu.be/BgWBXKtAFzQ
The inner tube slides up and pushes the flapper out of the way and protects it.
The negative is that you can't push against much of a pressure difference.
But it wouldn't need to click into place.
