Screw in nipple? For leg bag emptier.

well... I will correct it soon

I bought some valves on taobao as in the pic underneath. Their name in English is "DC24V normally closed drain valve". I tested them with a 24V power source and I see they work. If connecting the valve to the power source, I hear a small sound and it opens. The problem is that its hole (gap?) when opening is too small. The water can only drip a little through the valve. It might take a day to empty just 500ml. Is there anything in the valve that I can modify or adjust to increase the water flow?

@tutatu: How long time does your valve take to empty a 500ml bag.

[Burgerman]

Theres a small hole that can be drilled out a little, with care.

Or fit this instead! diaphram pump. It wont leak under gravity. You could fire urine about 3 metres... https://www.mudah.my/Electric+Fuel+Pump ... 333082.htm

http://www.nexusmodels.co.uk/kavan-elec ... -0190.html This is a gear pump. It will leak at the bottom. THIS will allow you to run the pump at the top where you sit. Just add tube. And fit under the seat or something. And fire it out of the top via a tube to wherever you want like a toilet, or your enemy...

This "diaphram pump" looks cool. Does it have a 24V one?
I am thinking about an urine gun (I have many enemies)

[Burgerman]

If you search you will likely find one. But it would likely be ok on 24v anyway. Fire further!

[snaker]

Is it this one?

probably smaller/better.

Its hard to know which are diaphram types.

Better... https://www.banggood.com/Diaphragm-Pump ... rehouse=CN

Oriffice on my valve are 1/4" or 6mm I think. I have 1.5l bag and time to take to empty it is about 2 minutes. Now I have mounted on right armrest mini taster, but it works only when I'm hold it, I hate to wait and hold pressed button for minutes - it takes for ages.


These days I will mount bluetooth relay switch, so when I'm in the hurry I can easily press in app button and continue driving

Can 12V pumps work with a 24V power source? Because I see the sellers warn buyers have to use the right power source.

Super mini pump 3--12V @£0.2.

Recommend to have a dozen of these gum sized voltage regulator boards always handy .

Are these pumps closed when not powered (like normally closed)?
Why do not they make a 24V version to ease things

[shirley_hkg]

LOOK AT THAT JET STREAM .

Powerful 12V Waterproof pump for windscreen washing .

A big revenge to enemy as BM advocated , or fun for irrigation .

[shirley_hkg]

Top gear for raising speed , if fired at the rear .

[Burgerman]

Thats a centrifugl pump. So it will allow urine to flow under gravity just like a pipe.

Diagpham pump wont flow till turned on.

Gear pump will flow a little (dribble...)

No you need 6, 9 or 2v regulator. Those are cheap.

[snaker]

Is it a diaphragm pump?

[Burgerman]

No. It has a motor. It is a gear pump.
If it has a motor AND one centre input, and one edge output pipe, its centrifugal.

[snaker]

Is this one correctly diaphragm? The title says "diaphragm" but it seems having a motor.

Theres 2 ways to work a diaphram pump. Electro magnet like a piston. Or a motor and a cam... If it has a motor it works with a cam. But you can still see its a diaphram pump from the design/shape.

Diaphram usually wont flow by gravity at low pressures. Since pressure too low to open valves. Self priming. And pulses... Lower pressures and low flow, quiet. Can pump air and uphill.

Centrifugal wont work unless full of water and will not self prime, cant do high pressures. Can do very high flow!
Gear can do very high pressures, and low flow. Self primes, dont like air much... And will allow a dribble to flow under gravity when off.

Diaphram pump.

I just fitted a pump, it work like a charm
35s to empty 500ml

Not sure I dare click it. To watch you pee!

Oh... I thought it was a vid!

[snaker]

Dont worry, it was a test with fresh water (not urine)

[Burgerman]

which pump type?

Geared or diaphram?

We need a vid!

[snaker]

It is truly diaphragm, supports 12-24V. The link of test video is above.

I tested the gun in the real life. Yesterday I went out in 8hrs, fired 5 shots, each took 10s. All were PERFECT, I got home with an empty bag

[Burgerman]

But what did you hit
