Football Vanishing Spray/ Foam
The football vanishing spray became popular during the World Cup (although it was developed several years earlier). It is capable of marking a temporary white line on a pitch that disappears after only 1 minute.
Do you think this could be adapted to last for...
LittleInch,
Yes, that’s right, and the pump will be completely decoupled.
I believe you’re right - that trialling maybe the only option. If the device was similar to a breach loaded weapon, standard ballistic mathematics could be used to determine the pressure required to move the object...
LittleInch, thanks for taking the time to respond.
Completely legitimate questions – I’m sure you can see my lack of experience in this field. Due to its application, I’ve been intentionally vague on some details, which I know is unhelpful (IP related rather than sinister I’ll add). But if I...
danw2, thanks - looks decent! though I'm not sure how I'd incorporate a cartridge valve into the design? Plus the flow rate is quite low compared to most traditional solenoids it seems
danw2, thank you. Yes a very good suggestion. The only issue been the linkage would be crucial, and need to be under significant tension to release the ball valve quick enough to allow max flow. For a hand tool it would also add considerable uneven bulk.
EdStainless, thanks for your reply!
This particular valve was just an initial test piece, it's only rated to 12 Bar. But it is indirect so should be pilot assisted.
(From the Manufacturer: Kv-value of 2.05 m3/h, which translates to a flow rate of 34.17 l/min at a differential pressure of 1 bar...
A query I could do with some help on (most likely basic fluid dynamics but struggling!)
Situation:
An industrial tool requires a small high pressure air chamber (1000 PSI+) an electrically controlled valve (currently a solenoid but could be something else) and an outlet pipe (1/4"). The valve...
