Air-cooled tower safety valve
Thread Content
Why are two safety valves installed at the inlet of the air-cooled tower? Can’t just use one? Are we supposed to prevent everyone from jumping when the pressure is high, by having another one ready?
It is recommended to learn the principles first before focusing on other things. For example, factors such as considerations regarding the pressure relief flow rate and the diameter limitations of safety valves. These are all things that designers need to take into consideration. The operation focuses only on the principles of existing devices; one just needs to know how to use and manage them. With all due respect. If you like this kind of questions, it’s best to send a photo of the actual scene along with a screenshot of the design for comparison. Additionally, it is best to consult with the design firm regarding this issue.
All safety valve designs take into account a certain discharge volume; in other words, the device you have isn’t sufficient – what I’m dealing with here is a safety valve
This is related to the discharge volume of the safety valve; some have one and some have two, with no fixed requirement regarding the number
Some designs are made for safety reasons, with both valves in use; safety valves generally do not activate simultaneously. Even if the set pressures are the same, testing one of them to determine its activation point does not cause the system to stop operating. There are also designs that use three valves, two in use and one as a backup – it depends on the intended purpose of the design
