Abstract

A protection valve includes: an input chamber into which air is introduced; a plurality of output ports through which air is discharged; and safety valves which open in response to a pressure increase on a primary side or close in response to a pressure decrease on a secondary side, the safety valves including a safety valve PVand a safety valve PV. An air flow path from the input chamber is branched into a first branch line and a second branch line, and a time lag-creating valve having an opening pressure higher than the safety valve PVis provided at a upstream of the safety valve PVin the second branch line, so that the safety valve PVcan open with a time lag after the safety valve PVopens, regardless of the difference between the opening pressures of the safety valves PVand PV
