This shows how fire sprinklers work and just how sensitive and fast they operate when heated up.

HhappyBirthday The pipe rust and oxideis as water is in it, So as a fire sprinkler guy like me, go out every couple years and flushes the pipes with fresh water and a lot of air behind it to flush all the rust and crap that is in it. why it stinks is for the fact water sits in there with the rust =stinky water

Yeah, often the water for the sprinklers is stored in tanks on the top of the building so they can even work without power. But often the sprinklers remain unused for several years, so the water also stays there for that long.

The liquid in the tube is glycerine. It expands and shatters the glass at temperatures between 155 and 165 °F (68.333°C.) When the glass breaks it releases the copper plug, shooting water to the round piece on the end which spreads the water outward eliminating the fire.

@serenitynaturalhealth9213 10 жыл бұрын

The liquid used in glass bulb sprinklers is a non-toxic proprietary glycerin solution that that expands when heated. If you closely examine the older full size bulbs you will see that the bubble size varies with the operation temperature. It is not so easy to see on the modern 2.5 and 3mm bulbs. Also the 'glass' is normally a quartz type of glass to ensure complete disintegration of the bulb on operation.

In response to the top comment... There was a device I had seen several years ago that I am now unable to find. No joke, but I think it was called "Dam it". You would get soaked trying to use it, but the plug was on some sort of extension rod and you would wedge the plug in between the diffuser and the orifice. If it meant saving valuables from water damage because of the accidental discharge of a head, getting soaked would be the price you pay instead of waiting on the FD.

@resqjason2 11 жыл бұрын

the liquid is alcohol. there is a small bubble in the liquid that determines the temp that the head will activate. the small bubble allows for fluctuations in temp without activating. once the temp gets to the activation temp the fluid expands to a point that the bubble is absorbed and the fluid has nowhere else to expand and ruptures the glass ampule allowing the water to spray. larger bubble in the glass the higher temp of activation. the fluid is colored to indicate temp as well

+ReverendTed I think the glass is holding the copper/brass "plug", but I don't think the plug holds back the water itself, but is holding back a spring loaded valve inside. This is pure conjecture, though. Couldn't find anything about the mechanism in a quick googlesearch.

@perspectivefilm 8 жыл бұрын

if your place is a cold place, dry pipe is used to avoid freezing water inside the pipe. try to notice how many standpipes are there or siamese, so the firetrucks' pumps shall render its pressure. dunno if im correct. if a dry pipe system is in your warehouse, try to find extinguishers around there. if you have an ample # following a minimun distance between extinguishers, thats good. they followed safety precautions. but what kind of warehouse is that?

@moparedtn 7 жыл бұрын

It is fairly common in regions with freezing conditions to have either a dry pipe system or some manner of "deluge" system. In a dry pipe system, the piping is full of compressed air, which holds the clapper shut in the dry pipe valve against the water supply; when a sprinkler activates, all system air is evacuated and allows the dry pipe valve to open and flood the system. In deluge systems, the piping is actually empty. When fire is detected, the deluge valve is actuated and the system is flooded with water.

@jfbeam 7 жыл бұрын

As others have said, that's a "dry pipe" system. It should be pressurized with air (nitrogen, co2, etc.) Many times that's to avoid freezing (and rust throughs), but it's increasingly common to avoid accidents flooding the building. If you knock the head off one, you have time to abort the water phase. (of course, everywhere I've ever been, the panel to do that is in a locked room -- on a different floor. There was a car dealership locally that broke one, and it took them half an hour to find the shutoff!)
