Abstract

A three-way valve with a socket comprises a main body (100), a rotation unit (200), a seal gasket (300) and a socket (400). The main body is provided with a water inlet communicated with a water supply source and two diversion ports (151) ; the seal gasket is mounted on the rotation unit; the rotation unit is rotatablely mounted on the main body; and by means of the relative rotation between the rotation unit and the main body the seal gasket is hermetically aligned with either diversion port or communicated with either diversion port in a staggered mode to realize the switch of discharge. The socket is mounted on the main body. The seal gasket comprises a bottom wall (310) and a peripheral wall (320) which is upwardly extended from the periphery of the bottom wall. The peripheral wall is mounted on the rotation unit and provided with a notch (321) for introducing the water into the seal gasket.
