After passing through the control valve, liquid chlorine

The pressure before and after the control valve for liquid chlorine is relatively high: 8 kilograms before the valve and 6.5 kilograms after it. Is this a process of throttling expansion? There is also a temperature difference in the liquid chlorine temperature before and after the control valve~ # hcbbs
If liquid chlorine is in a liquid state both before and after the valve, it is not throttling expansion but rather pressure reduction; expansion should involve a process of vaporization that absorbs heat. Such as before and after the expansion valve in a refrigeration system: liquid on the inlet side, gas on the outlet side (possibly containing undevaporated liquid droplets)
Then why is there a temperature difference before and after that valve? Where does all this heat go?
It was clearly explained upstairs – there will be no temperature difference
It seems that throttling expansion can occur only when the gas pressure decreases or the liquid turns into a gas. Let’s guess the process as described by the poster: in front of the control valve, there is liquid chlorine filling the pipe, while behind the control valve, the pipe is connected to a vaporizer or some container. In this case, the pipe behind the control valve may not also be filled with liquid, so frosting could occur in that pipe. The heat comes from the air and the condensation of water vapor in the air.
The pipe is also full after that, huh~ I guess what’s happening here is that liquid chlorine vaporizes behind the control valve; I’m not sure if that’s correct
The pipe is also full after the valve, huh~ I speculate that vaporization of liquid chlorine occurs after the control valve; it’s impossible for the pipe to be full after that point. The pressure of liquid chlorine is 8 kilograms before the control valve and 6.5 kilograms after it. If you consider the conditions under which chlorine liquefies, you’ll understand it right away: lol:lol
