とする弁機構を備えた管継手。[Claims for Utility Model Registration] A main body formed hollow and having a holding means for holding a tube inserted for connection and a valve seat provided therein; a pressing body that is loosely fitted into the main body so as to be movable back and forth a predetermined distance and is provided with a first flow path that communicates the inflow side and the outflow side of the main body; a second flow path that communicates the inflow side and the outflow side of the pressure body and has a cross-sectional area larger than the cross-sectional area of the first flow path; The tube is fitted onto the outside so as to be movable back and forth a distance, and includes a valve body that can open and close the valve seat and the inflow side of the first flow path as the pressing body moves back and forth, and the tube is not inserted into the main body. In this state, the valve body closes the valve seat and the inflow side of the first flow path, the tube is inserted into the main body, and the end of the tube pushes the pressing body a predetermined distance toward the inflow side of the main body. When moved forward, the valve body opens only the first flow path, and when the pressing body is further advanced, the valve body opens the valve seat and the first flow path. A pipe fitting equipped with a valve mechanism.
