How do steam traps work?
Answers:
1- Float and bucket: this like like your flush box on your toilet, when the condensate accumulates in the bucket, the float goes up and the pressure of the steam behind it pushes the condensate out the pisser.
2- Thermodynamic traps: this works like the thermostat on you car radiator..the condensate temperature contracts the liquide in the bellows and a pin unblocks the pisser till the condensate leaks out. The steam hits the bellows, expands it and the pin blocks the pisser.
3- Inverted bucket traps: simmilar to float and bucket but works in the opposit sense.O, thats enough for tonight. Hope you learned somthing.you can go to spyraxsarco.com and get the nitty grittys
It depends on the type of steam trap. In all of them, you want to keep the steam inside while draining out the liquid water. First, all steam traps are in low points of the system so that gravity can be used to drop the liquid out. One type of steam trap has alchohol in bellows that is attached to the stem to open and shut the valve. When liquid water is coming down the line, it cools the alchohol and opens the valve. As soon as hot steam hits the bellows, it evaporates the alchohol, expanding the bellows, and shutting the valve. Thereby keeping the steam inside.
Another valve for higher pressure systems uses surface area. When the liquid water comes down, it basically floats up the stem and opens the valve and allows water to flow out. Steam comes in, and it presses on the top of the valve (which has more surface area and can apply more force) and then shuts the valve, trapping the steam inside.
It is a lot harder to describe without pictures. But that is basically how a lot of them work.
Isn't there some clever sods, thank god we only have to work with condensing boilers. couldn't stand having to trap the steam first. Had enough steam when I traped the X wife ROFL
