spool valve connections?

Unread postAuthor: ramses » Fri Feb 13, 2009 11:36 am

I plan on making a spool valve, and I was wondering what you thought the best way to make the connections to the side of the pipe would be. It can't protrude into the the pipe at all, as that would interfere with the operation of the valve. I attached a diagram in case I am not making this clear

yeah, the copper tubes should be the same size, but I am lazy.

Build your valve with two tee fittings and then just screw the pipe onto the part perpendicular to the linear ones (I hope you get that).

actually I am considering the epoxy casting method. I get what you are trying to say with the Tees, but the holes must be in very specific places (this would be a metering spool valve).

do you think I could just JB weld tubing to the holes and the area around the holes, because otherwise a lot of epoxy would be required.

JB weld would probably be better,anything nice and thick-I've seen locktight epoxy gel.It's nice and thick and I didn't have any problems with it getting into bad areas. If anything gets into the casing then the valve is pretty much useless unless you can get all the dried epoxy out.

It's debatable in the real world no but in schools anythings a weapon. You could put a piece of paper over the holes so epoxy doesn't get in that would probably minimize the overflow...

Don't forget some schools even have wood shop and chemistry classrooms with flammable gas lines leading right up to desks!

Don't even get me fired up on that one. I was burned once last year.

You can tell how awesome a cannon is by the pressure used.

lol no, I haven't even begun to make the valve. I was wondering if I could smooth the leakage in study hall.
