I read many posts on Haichuan regarding water-sealed safety valves, and it seemed that none of them explained things very clearly. 1. Could some expert please explain in detail the working principle of the water-sealed safety valve? Thank you! 2. The four small openings on the water-seal safety valve: one of them is for water inlet, while the other three seem to be for drainage. But what is their specific function? When is it used? Could some expert please help explain this? 3. After lifting the valve used to break the water seal at the bottom to open the valve plate, and while water is flowing, can rotating this valve downward restore the function of the water seal?
There isn’t actually much information available on DuNiang. ===================== Working principle of water-sealed safety valves: https://bbs.hcbbs.com/thread-95906-1-1.html (Source: Huahai Chuanliu – Haichuan Chemical Industry Forum)
