Help me buy this thingy!
« on: December 03, 2014, 01:32:13 PM »
No, this is not an attempt to justify antimustachian spending!

Now that I have avoid the IMP (internet mustachian police), let me ask for your help in puchasing this "thingy".

I am looking for a type of plumbing valve that does what a tee does except that the third arm (the one pointing perpendicular to the other 2) should be a valve instead of just a tee. Even better would be a spring valve instead of a ball valve.

Is there a specific term for this type of tee/valve?

I need this to connect to a vacuum pump so that I can let air in when I need to. One arm of the tee would be connected to my pump, one to my vacuum recipient and the other to my "intake" tube.

I am looking to replace the one that I have currently because it lets air in and I lose my vacuum. The one that I have is basically a Y tee with a 45 degree with a springloaded button on top that either blocks air or lets air in when I press it. Trouble is, either the seal is gone or the spring needs to be replaced. A suggestion for where to buy a small but strong spring would also be appreciated.

So can anybody help me with this? Sorry if this is unclear, I have no idea what the technical terms are for most of what I described.

Maybe I am misunderstanding what you are looking for but would it be something like these?

It wont work with a 3 way ball valve since it only allows 2 sides of the valve to be "connected" at any which point.

I need a valve that will connect the 3 sides and let air into the other 2 sides when I want it.

Try googling manual vacuum release valve or vacuum breaker.

Could you add a drawing or schematic?  I'm not sure from your description exactly what you are trying to do here.  It does sound like a check valve might be what you are looking for but I'm not really sure based on your description.

Ok, here is my best try at a drawing.

The orange bar is the moving part that is pushed by a spring. Pressing the button allows a channel to be formed with the intake port and releases the vacuum.

For reference, this is a fairly small part, maybe 2 inches by 2 inches and goes on a fairly weak pump. I don't need anything industrial.
