Annular hydraulic double-channel control valve

The utility model discloses an annular hydraulic double-channel control valve which comprises an external mechanism and an internal mechanism. The external mechanism comprises an upper joint, an outer pipe, an outer sleeve and a lower joint which are sequentially connected from top to bottom; the internal mechanism comprises a main shaft, a spring, a door closing sleeve, an inner bushing and a sealing cylinder; the annulus hydraulic double-channel control valve is provided with an annulus oil extraction channel and a large-diameter water injection channel. An annulus oil outlet channel is formed between the control valve and the production oil pipe, during normal production, the control valve can be opened by controlling the hydraulic control pipeline on the ground in a pressing mode, and annulus oil extraction is achieved; when the oil extraction channel needs to be closed, the hydraulic control pipeline relieves pressure, the control valve is automatically closed, and forward and reverse high-pressure seali
