Compressor with differential pressure relief valve

The invention discloses a compressor with a differential pressure relief valve. The compressor comprises a shell, a static scroll plate, a dynamic scroll plate, a shutoff valve assembly and the differential pressure relief valve; an accommodating space is formed in the shell; a high-pressure cavity is formed between the upper end of the static scroll plate and the shell, and an exhaust duct is further arranged on the static scroll plate; the upper end of the exhaust duct communicates with the high-pressure cavity; the movable scroll plate is meshed with the static scroll plate, and a compression cavity is formed between the static scroll plate and the movable scroll plate; the compression cavity communicates with the lower end of the exhaust duct; the shutoff valve assembly is mounted at the upper end of the exhaust duct; and the differential pressure relief valve is mounted on the static scroll plate. According to the application of the compressor, by taking advantage of the differential pressure characteris
