The subject innovation relates to a door hinge capable of multi-stage hydraulic control. Piston present design is that the upward and downward movement engages the forming the exterior housing 100, with the housing projecting into the top of 100, a relative motion to the hinge axis rotation unit 200 is, and the lower portion of the hinge shaft rotation 200 in the section 300 and, as a spring (400) for controlling the spring force in the lower portion of the piston part 300, and bottom cap 120 to be assembled to the bottom surface of the housing body 110. the housing body 110 It is filled with a fluid provided in the lower cap 120 and includes a flow rate control rod portion 500 to which the fluid is formed with a passage 511 therethrough and down to move to the lower cylinder chamber (110c), and; The housing 100 when the piston the vertical movement after the lowering of the forming the upper and lower flow path (1100) 1200 on the outside of the body so as to be circulated in communication with the cylinder chamber (110c), the piston unit 300, the boss the flow guide portion 1000 hayeoseo to allow the upper and lower-side passage opening with respect to the piston in that position and so as to form; When normal and reverse rotation in the flow path guide portion 1000 is made be equipped with a flow control bolt (2000) to be the flow rate of one flow path of the flow path control.
