An integral valve core type cock relates to valves and comprises a body (1) and a valve core assembly, wherein a knob hole is formed in the wall of the body (1); a circular bead and a ring groove are arranged on the inner wall of the body (1); a retainer ring assembly is arranged in the ring groove; the body (1) is provided with a knob (2) in the knob hole; the valve core assembly comprises an inner valve seat (3), an outer valve seat (4), a spherical valve core (5) and a valve seat bush (6); the valve seat bush (6) is seated on the circular bead in the body (1); the inner valve seat (3) is fixed at one end where the circular bead is arranged, on the body (1) in a pipe cavity of the valve seat bush (6); the outer valve seat (4) is arranged at a port of the other end of the valve seat bush (6); an outer end face of the outer valve seat (4) is supported against the retainer ring assembly; and the spherical valve core (5) is connected with the knob (2) through a torsion member (8). The integral valve core type cock has the advantages of compact structure, favorable stability, capability of replacement for the whole set, convenience and quickness in maintenance and the like. The wall thickness of the body is uniform and the bearing capacity is strong; and cracks caused by stress concentration are avoided.
