The utility model relates to a pipeline connecting joint. The utility model discloses a pipeline threaded connection joint with good sealing performance. In the prior art, when two sides of a sealingring are pressed, the sealing ring is inwards sunken and deformed along the radial direction; therefore, the sealing effect is reduced and even the sealing fails. The connector comprises a male connector, a female connector and a sealing ring, a mounting groove is coaxially formed in one end of the female joint; internal threads are arranged on the inner sides of the mounting grooves; the outer diameter of the sealing ring is equal to the bottom diameter of the mounting groove; the sealing ring is coaxially accommodated at the bottom of the mounting groove; the male connector comprises a threaded end with external threads coaxially arranged on the outer side, a positioning ring is coaxially arranged on the end face of the threaded end, the outer diameter of the positioning ring is equal tothe inner diameter of the
