Can a safety valve and an exhaust pipe share the same outlet?
Thread Content
I would like to ask fellow sailors: can the safety valve on the reaction tank and the exhaust pipe share the same outlet? Now, due to an insufficient number of pipe outlets, we want to share them. I checked the relevant standards but found no requirements in this regard
It is recommended to draw a simple diagram to illustrate it.
What is not prohibited by law may be done. Should the safety valve be connected to the exhaust pipe at the inlet or at the outlet?
The inlet shares the equipment connection, while the outlet is separate
Is there any standard basis for this? The connections for the main equipment are insufficient; otherwise, this approach wouldn’t be adopted
It is acceptable if the diameter of the inlet pipe meets the discharge requirements, and it will pass the inspection by the expert team as well
When the safety valve is in discharge mode, the inlet pipe diameter only needs to meet the corresponding allowable pressure drop requirements.
It is best not to set up a common port, as it is difficult to detect leaks in the safety valve once they occur. For reference.
Conventional safety valves are sensitive to back pressure; if a common tailpipe is used, the discharge from that tailpipe may affect the proper operation of the safety valve. For bellows safety valves, they can be shared since they are not sensitive to back pressure. Conclusion: Whether to share it or not depends on evaluating whether the impact of the tail pipe’s operation on the relief valve’s discharge performance remains within an acceptable range.
