Abstract

The invention relates to the field of unblocking equipment, and discloses a valve unblocking device which comprises a main pipe body, and the main pipe body is provided with a connecting part used for being connected with a to-be-unblocked valve and an unblocking cavity allowing blockages in the to-be-unblocked valve to pass through. The guide pipe is provided with a blockage dredging needle penetrating through the blockage dredging cavity, the guide pipe can reciprocate relative to the main pipe body in the axial direction of the main pipe body so as to drive the blockage dredging needle to dredge the valve to be dredged, and the guide pipe and/or the main pipe body are/is provided with a sewage discharging part communicated with the blockage dredging cavity; and the driving part is arranged to be capable of being operated on the side opposite to the forming direction of the pollution discharge part so as to drive the guide pipe in the axial direction of the main pipe body. The driving part is arranged to be capable of being controlled on the side opposite to the opening direction of the sewage discharging part, and the guided blockages cannot be splashed to the body of an operator, so that the operator can conveniently clean the blockages, and the personal safety of the operator can be guaranteed.
