Are there any regulatory requirements regarding the installation of safety valves in deaerators? Original post: Since the deaerator already has a water seal, is it necessary to install an additional safety valve? https://bbs.hcbbs.com/thread-321871-1-1.html (Source: Haichuan Chemical Industry Forum)
Standard: Technical specifications for pressure deaerators in power plants – JB/T10325-2002 \"Technical specifications for boiler deaerators\". The water seal is used in atmospheric oxygenation devices, where it can serve as a overflow mechanism and a safety valve. Safety valves and electric globe valves can also be used; of course, a water seal can be installed along with a safety valve. Electric globe valves are often installed at the overflow ports of pressure deaerators, along with safety valves.
