Air compressor soft coupling for high-pressure pipeline cleaning. The main solution is to address safety hazards in the cleaning of existing air compressor pipelines. The upper part of the check valve is connected to a snap ring through an elbow, and the other end of the elbow is connected to a short pipe C. The short pipe C is connected to a fixed frame from the outside, and the fixed frame is connected to two air injectors. The rod is symmetrically arranged along the axis of the short pipe C. The connecting rod of the air injector rod is connected to the safety ring. The soft connection device can prevent the quick coupling from falling off when the air compressor vibrates, prevent high-pressure media from entering the air compressor pipeline and damaging the air compressor, and avoid safety hazards caused by false alarms and disassembly under pressure.
