Gas phase temperature measurement device for exhaust end of liquid injection screw compressor

The invention discloses a gas phase temperature measurement device for an exhaust end of a liquid injection screw compressor. The liquid injection screw compressor comprises a compressor body and an outlet short joint connected with an exhaust port of the compressor body. The gas phase temperature measurement device for the exhaust end of the liquid injection screw compressor comprises a temperature measurement element, a sleeve, a gas-liquid separation part and a sealing structure. The sleeve penetrates through the side wall of the outlet short joint, the bottom of the sleeve extends into a central hole of the outlet short joint, and the sleeve and the outlet short joint are connected to each other. The gas-liquid separation part is fixed at the bottom of the sleeve, the sealing structureis arranged at the top of the sleeve, a temperature measuring cavity is formed between the gas-liquid separation part and the sealing structure, and the gas-liquid separation part is used for blocking a liquid-phase medium a
