を特徴とする空気槽のドレン排出弁の診断装置。[Claims for Utility Model Registration] A drain discharge valve for an air tank that determines whether the operating state of the drain discharge valve is good or not for discharging the drain in the air tank storing compressed air sent from an air compressor at regular time intervals. A diagnostic device, comprising: a pressure sensor that detects the pressure in the air tank;
Pressure determination means for determining whether or not the pressure in the air tank is decreasing after a time longer than the predetermined time interval has elapsed from an arbitrary time based on the output of the pressure sensor, and when the pressure is not decreasing; , drive determining means for determining whether or not the air compressor has been driven during the predetermined period of time, and determining whether the operating state of the drain discharge valve is good or bad based on the determination result of the drive determining means. A diagnostic device for a drain discharge valve of an air tank, characterized in that:
