Auto-pressure release valve? For storing while inflated?

[Jomama]

Shot in the dark here... wondering if any of the rafters have ever come across something like this..?

I store my boat on a trailer in the parking area all summer... I cover it with tarps and such, but still feel the need to watch the tubes constantly so they don't expand when we have consecutive days of warm sunny days... I squeeze it into the garage when I'll be away and cant do this, but its much nicer to just leave it out all summer...

So I was wondering if there are, have been, or if anyone has come up with their own... I'm thinking of some form of auto pressure relief valve that you could put on each of your valves on a raft, and have it take over the monitoring that I'm doing daily... Seems like it could be a very simple device... Just releasing air as the pressure builds in the heat of the day at some pre-set pressure....
Is this something available that I've just never come across? I cant be the first one to think of it...

Cheers, thanks in advance for any reply's...

You could use the relief valves that are often put in inflatable floors. You'd have to cut new holes for them, but that's not really hard to do. I've never seen relief valves that installed in the normal fill holes though.

Yeah Jim, its appearing its never been done, I searched around google and nothing came up except the pressure relief valve found in some inflated floors..

I'm going to pick one up and see if I can figure out a way to turn it into a "plug" that you could insert into a regular HR valve.
