The invention discloses a pressure control valve for an independent hydraulic control packer. The pressure control valve comprises a central pipe, an outer sleeve, an one-way valve, and a pressure relief device. The outer side of the central pipe is sleeved with the outer sleeve in a hollow manner, and a hydraulic control oil flow annular is formed between the outer sleeve and the central pipe; anoutwardly convex annular platform is arranged on the outer wall of the upper end of the central pipe, and the upper end of the outer sleeve is connected with the outer wall of the annular platform; the annular platform is provided with a separate axial upper hydraulic oil passage, the lower end of the outer sleeve is provided with a separate axial lower hydraulic oil passage, and the upper hydraulic oil passage and the lower hydraulic oil passage are communicated with the hydraulic control oil flow annular; and a lower port of the upper hydraulic oil passage is connected with the one-way valve through which the hydraulic oil can only flow downward, and the pressure relief device is arranged on the outer wall of the central pipe. According to the pressure control valve for the independenthydraulic control packer, by adopting a built-in hydraulic oil single-fluid design, flow direction control of the hydraulic oil in hydraulic control pipelines is achieved, by adopting a double-pistonlinkage design, the opening and closing of a double wall cavity of the pressure control valve and oil pipeline passages are achieved, and demands of downhole rapid pressure relief and unsealing of a marine hydraulic control packer are met.
