[PSUBS-MAILIST] HP Stop valve for gauges.

[James Frankland <jamesf@guernseysubmarine.com>]

Hi All,

 

Can i ask people's opinion on this.  Due to an oversight on my part, i am missing a through hull for a depth gauge.

 

So, i have an idea.  I was thinking of putting the gauges on the same line as the HP air for the forward tank.  In this configuration.  See fantastic picture attached (i am at work so i only have microsoft paint).  Hope the pic makes it through.

 

The idea is i have the through hull, stop valve, t piece (or even a "Y" piece) leading to 2 x redundant chemical protected gauges on one "t" and on the other, the check valve followed by the hp air.  Easier to see in the picture. 

 

This should allow water to the gauges while not filling the whole line to the hp tank. 

The check valve is 400 bar with a cracking pressure of 5psi.

 

The only problem i can see is that when blowing air, it may interfere\damage the gauges?  Bearing in mind they are chemical protected so have a diaphram that will protect them from the water itself.

 

Unless anyone has any better ideas.  (I will have a normal diviers gauge outside, but i want proper gauges inside).

 

Thanks

James
