Function of the check valve in the compressor outlet pipeline

What is the function of the check valve in the compressor outlet pipeline? Can a compressor start without a check valve in its outlet pipeline? This post was last edited by *ebinan on 2009-4-3 11:26]
I forgot to mention it – this compressor is a reciprocating single-stage compressor
Yes, the outlet valve disc of a reciprocating compressor is itself a one-way valve
To prevent high pressure from flowing back from the high-pressure pipeline at the outlet of the unit to the inlet of the unit, thereby avoiding accidents where high pressure enters the low-pressure system, check valves are usually installed behind the outlet valve. In the past, these were mostly ordinary flap-type check valves; nowadays, many units use Holberg’s disc-type check valves instead
