Abstract
The utility model relates to the technical field of gas pipelines, in particular to a pressure measuring instrument connector. The pressure measuring instrument connector comprises a screw cap, wherein a pressure measuring instrument connector body penetrates the screw cap, and a valve core device is transversely arranged in the middle of the pressure measuring instrument connector body and comprises a valve core body transversely arranged in the pressure measuring instrument connector. A nut is arranged at one end of the valve core body in a matched mode, and a second washer is arranged between the valve core body and the nut. The pressure measuring instrument connector can test pressure in the gas pipelines through the valve core device arranged on one side of the pressure measuring instrument connector body and regulate the tested pressure in the gas pipelines.
