30. What are the functions of the safety valve and the manual valve/vent valve at the compressor outlet?
Literally, the effect is obvious!
A safety valve is an automatic valve that opens when the maximum operating pressure is exceeded; once it opens, gas is released into the treatment system, primarily to protect the equipment； Above the vent valve is a manual valve, which must be manually opened and closed during processes such as purging and replacement, to allow gases to be discharged into the treatment system.
A safety valve is an automatic valve installed to maintain pressure; it opens automatically when pressure exceeds a certain level and closes automatically when pressure drops. The manual valve and vent valve are provided for pressure regulation during the start-up/shutdown of the equipment as well as during normal operation. For reference.
(1) The function of the outlet safety valve is to prevent the pressure inside the compressor from exceeding the designed operating pressure； (2) The function of the manual valve and drain valve is to ensure that the centrifugal compressor can meet the requirements of the process operation during startup.
