The invention discloses a three-way valve with a socket, comprising a main body, a rotation unit, a sealing pad and a socket. The main body is provided with a water inlet and two water-dividing ports communicated with a supply water source; the sealing pad is assembled on the rotation unit; the rotation unit is rotatably assembled on the main body; and the sealing pad is driven by the relative rotation of the rotation unit and the main body to hermetically align with the water-dividing ports or communicate with the water-dividing ports in a staggered mode to realize the switching of water yielding. The socket is assembled on the main body; and the sealing pad comprises a bottom wall and a peripheral wall, wherein the peripheral wall is formed by upwards extending from the periphery of thebottom wall, the periphery wall is assembled on the rotation unit and provided with a nick for introducing the water into the sealing pad, the bottom wall corresponds to the water-dividing ports, andthe sealing performance between the bottom wall and the water-dividing ports is improved by using the water pressure and the water gravity of the sealing pad. The three-way valve with the socket comprises the following advantages of optical sealing performance, difficult generation of burrs on the sealing surface of the main body, easy control of the production and reduction of manufacture cost.
