| description | The invention discloses a quick joint, which comprises a male joint and a female joint which are connected in an inserted mode, positioning shafts are arranged in the male joint and the female joint correspondingly, and valves are rotationally connected to the positioning shafts; and valve jacking-open structures are arranged at the positions, close to the inserted-connection ends, of the positioning shafts. The male joint and the female joint are each of an overturned-type valve structure, and under the situation of the equal maximum pipeline sectional area, the circulation cross-sectional area at the valve is increased. At the valve butting position, under the situation of the equal flow and the equal circulation cross-sectional area, the maximum sectional dimension of the quick joint isdecreased effectively, when liquid flows through the quick joint, the change of the cross-sectional area is small, and the pressure loss during liquid flowing is effectively reduced.
