An improved faucet control valve has a valve seat, a spring, a one-piece valve stem, an expanded end, a flexible hooking portion and a control unit. The one-piece valve stem manufactured integrally enables to realize convenient manufacturing, cost reduction and structural simplification of control members. The one-piece valve stem is only required to penetrate the valve port of the valve seat from top to bottom, enabling engagement of the flexible hooking portion for simple and fast assembly.

1. An apparatus comprising: a faucet having a seat body and an outlet and at least one vertical inlet opening, said outlet being depressed onto said seat body and having a discharge pipe, the vertical inlet opening extending vertically through said seat body and said discharge pipe, said faucet having a bottom inlet and a connection pipe positioned between the vertical inlet opening and said discharge pipe; anda control valve positioned in the vertical inlet opening so as to open or close said bottom inlet and said discharge pipe, said control valve comprising: a valve seat assembled into the vertical inlet opening, said valve seat having a valve port passing vertically through a center of said valve seat and an assembly groove into a top surface of said valve seat, said assembly groove connected to said valve port, said valve seat having a through-hole formed on a peripheral wall thereof, said through-hole connected to said connection pipe and to said valve port;a spring positioned into said assembly groove of said valve seat;a one-piece valve stem limited to said valve port by penetrating said assembly groove downwardly, said valve stem having a top end and a bottom end and a peripheral wall, said valve stem having a water guide slot positioned adjacent to said bottom end of said valve stem and corresponding to said through-hole of said valve seat, said peripheral wall of said valve stem having a first seal ring in spaced relation to said water guide slot;an expanded end integrally formed with and at said top end of said valve stem, said expanded end abutting a top end of said spring;a flexible hooking portion integrally formed at said bottom end of said valve stem, said hooking portion having a groove formed at a bottom center thereof, said valve stem insertable into said valve port of said valve seat such that the flexible hooking portion is flexibly set outwardly when said valve stem penetrates downwardly toward said valve port so as to enable engagement of the valve stem, said valve stem having a second seal ring positioned on said peripheral wall thereof between said flexible hooking portion and said water guide slot; anda control unit positioned above said valve stem, said control unit suitable for operating and pressing against said expanded end so as to drive said valve stem downwardly and to force a disengagement of said flexible hooking portion and the second seal ring from said valve port of said valve seat such that said bottom inlet is connected to said water guide slot and said through hole and said connection pipe and said discharge pipe for water discharge. 2. The apparatus of claim 1, said control unit having an abutting ring and a locating ring and an actuating rod, said abutting ring positioned above said valve seat, said locating ring being screwed into the vertical inlet opening and against said abutting ring, said actuating rod secured onto said abutting ring via a pivotal shaft, said actuating rod having a pressing portion at a bottom end thereof, said actuating rod being rotatable so as to switch said pressing portion for pressing downwardly or for releasing said expanded end. 3. The apparatus of claim 1, said at least one vertical inlet opening comprising a pair of vertical inlet openings, said faucet having a cold water inlet pipe connected to a bottom of one of said pair of vertical inlet openings, said faucet having a hot water inlet pipe connected to a bottom of the other of said pair of vertical inlet openings. 4. The apparatus of claim 1, each of said first and second seal rings formed of a material selected from the group consisting of rubber, silicone and polymeric material.
