May I ask, the cooling circulating water is used to regulate the temperature of the condensate; should the control valve be installed on the inlet pipe or the return pipe of the circulating water?

The cooling circulating water is used to regulate the temperature of the condensate; should the control valve be installed on the inlet pipe or the return pipe of the circulating water? Why
Don’t ask such questions right from the start – they’re too trivial. First, do some searching; these kinds of questions have been asked many times on forums, with various opinions expressed, and there is no single answer
Of course it’s backflow; if you control the inflow and keep the outlet valve of the heat exchanger fully open, it will ultimately result in the heat exchanger possibly not being filled properly with fluid, or in insufficient heat exchange
Sir, what exactly is the reason? I hope you can advise me
In a heat exchanger, as long as the water flows from lower to higher levels, isn’t it always full at both the inlet and the outlet?
Adjusting this is all for controlling the return water, right? It should be all about controlling the return water; I’ve never seen anything related to controlling the inlet water. .
Can you ensure that no bubbles are formed during the regulation process of the control valve? ?
Can’t it be set so that access is restricted in both cases? Use whichever one you prefer
Only a few senior mages know the real reason: *It is customary to install control valves on the return water pipes, in order to prevent an increase in temperature of the circulating water inside the heat exchanger, which could lead to a decrease in pressure and thus the desorption of dissolved oxygen, causing oxygen corrosion of the heat exchanger.
