remove air from fluid?

[mecoop]

Hello-

I have an application that I think can be solved two different ways, the only problem is that I cannot seem to find any valves that do what I need them to do.

We have a fludic system that has three lines that are pumped into a single line. On occasion we have one of the three lines pulling only air. A portion of our fluid has a soap in it, and it bubbles when this happens. We need the fluids to pass through while eliminating the bubbles/air.

So I need either a valve that can allow fluids to pass through, but releases air OR a valve that only opens when a fluid passes through...I understand that this may require a sensor and and an electric valve. Please let me know if any of this is availible, or even if it exists. We are looking for this in our system with either 1/8 or 1/4 inch ID tubing. Thank you very much for your time and help.

Actually I didn't understand your application part. It is a little confusing, but there are humidity sensors you can use for measuring the fluid level OR simply you can plug two wires in the pipe, if the fluid is conductive , and use one of them as a cathode and the other as a driver for the electrical valve. There are valves in the market that works with electrical drivers. So when the fluid passes the circuit will be closed and the valve will work.

I hope this helps.

Are you sure you have the right forum? Don't you want the fluid mechanics one?

Hello Alex,
Have you thought of a vortex type valve. They are simple to fabricate. You push in the air/fluid mix tangentially at one end of a cylinder, allow it to rotate downwards towards an exit stream 180 degrees from the inlet. You then have a bleed hole at the top center of the cylinder and allow the air to release. There are valves and sensors capable of doing this as well but this is a simple method. Just a thought.

I don't quite understand the applicaton either. But with that said...

Have you thought about using an accumulator of some sort? Basically it's a reservoir or tank where the liquid may come in the top and is pulled out the bottom. With this arrangement, the liquid/soap solution may still bubble, but only non-bubbly liquid is pulled out the bottom.

Just a thought...
