Bolts on heat exchanger/safety valve
Thread Content
Ask the experts for advice: As shown in the picture, what is the inner bolt on the safety valve used for? What's your full name? What are the two bolts (1 and 2) on the heat exchanger used for? What's the scientific name?
Definitely not. What is the purpose of sewage discharge? When will the sewage be discharged?
Neither. I also want to know what it is,
Is there anyone who can reply? Thank you.
The bolts on the safety valve should be the locking screws for the internal valve seats. The plug on the heat exchanger pipe is the connection port used during pressure testing of the heat exchanger.
The safety valve is the jackscrew that locks the ring gear of the valve group inside.； Cooler 2 should be a double cooler with two cylinders indirectly balancing the pressure pipes.
Thank you, this should be the correct answer. But the heat exchanger is all on the tube side, so why are there two pressure testers?
You talked too deeply about the heat exchanger and I don’t understand it very well. Can you explain it in more detail?
